+1 Notes on the Free Translation Project
+***************************************
+
+Free software is going international!  The Free Translation Project is
+a way to get maintainers of free software, translators, and users all
+together, so that free software will gradually become able to speak many
+languages.  A few packages already provide translations for their
+messages.
+
+   If you found this `ABOUT-NLS' file inside a distribution, you may
+assume that the distributed package does use GNU `gettext' internally,
+itself available at your nearest GNU archive site.  But you do _not_
+need to install GNU `gettext' prior to configuring, installing or using
+this package with messages translated.
+
+   Installers will find here some useful hints.  These notes also
+explain how users should proceed for getting the programs to use the
+available translations.  They tell how people wanting to contribute and
+work on translations can contact the appropriate team.
+
+   When reporting bugs in the `intl/' directory or bugs which may be
+related to internationalization, you should tell about the version of
+`gettext' which is used.  The information can be found in the
+`intl/VERSION' file, in internationalized packages.
+
+1.1 Quick configuration advice
+==============================
+
+If you want to exploit the full power of internationalization, you
+should configure it using
+
+     ./configure --with-included-gettext
+
+to force usage of internationalizing routines provided within this
+package, despite the existence of internationalizing capabilities in the
+operating system where this package is being installed.  So far, only
+the `gettext' implementation in the GNU C library version 2 provides as
+many features (such as locale alias, message inheritance, automatic
+charset conversion or plural form handling) as the implementation here.
+It is also not possible to offer this additional functionality on top
+of a `catgets' implementation.  Future versions of GNU `gettext' will
+very likely convey even more functionality.  So it might be a good idea
+to change to GNU `gettext' as soon as possible.
+
+   So you need _not_ provide this option if you are using GNU libc 2 or
+you have installed a recent copy of the GNU gettext package with the
+included `libintl'.
+
+1.2 INSTALL Matters
+===================
+
+Some packages are "localizable" when properly installed; the programs
+they contain can be made to speak your own native language.  Most such
+packages use GNU `gettext'.  Other packages have their own ways to
+internationalization, predating GNU `gettext'.
+
+   By default, this package will be installed to allow translation of
+messages.  It will automatically detect whether the system already
+provides the GNU `gettext' functions.  If not, the included GNU
+`gettext' library will be used.  This library is wholly contained
+within this package, usually in the `intl/' subdirectory, so prior
+installation of the GNU `gettext' package is _not_ required.
+Installers may use special options at configuration time for changing
+the default behaviour.  The commands:
+
+     ./configure --with-included-gettext
+     ./configure --disable-nls
+
+will, respectively, bypass any pre-existing `gettext' to use the
+internationalizing routines provided within this package, or else,
+_totally_ disable translation of messages.
+
+   When you already have GNU `gettext' installed on your system and run
+configure without an option for your new package, `configure' will
+probably detect the previously built and installed `libintl.a' file and
+will decide to use this.  This might not be desirable.  You should use
+the more recent version of the GNU `gettext' library.  I.e. if the file
+`intl/VERSION' shows that the library which comes with this package is
+more recent, you should use
+
+     ./configure --with-included-gettext
+
+to prevent auto-detection.
+
+   The configuration process will not test for the `catgets' function
+and therefore it will not be used.  The reason is that even an
+emulation of `gettext' on top of `catgets' could not provide all the
+extensions of the GNU `gettext' library.
+
+   Internationalized packages usually have many `po/LL.po' files, where
+LL gives an ISO 639 two-letter code identifying the language.  Unless
+translations have been forbidden at `configure' time by using the
+`--disable-nls' switch, all available translations are installed
+together with the package.  However, the environment variable `LINGUAS'
+may be set, prior to configuration, to limit the installed set.
+`LINGUAS' should then contain a space separated list of two-letter
+codes, stating which languages are allowed.
+
+1.3 Using This Package
+======================
+
+As a user, if your language has been installed for this package, you
+only have to set the `LANG' environment variable to the appropriate
+`LL_CC' combination.  If you happen to have the `LC_ALL' or some other
+`LC_xxx' environment variables set, you should unset them before
+setting `LANG', otherwise the setting of `LANG' will not have the
+desired effect.  Here `LL' is an ISO 639 two-letter language code, and
+`CC' is an ISO 3166 two-letter country code.  For example, let's
+suppose that you speak German and live in Germany.  At the shell
+prompt, merely execute `setenv LANG de_DE' (in `csh'),
+`export LANG; LANG=de_DE' (in `sh') or `export LANG=de_DE' (in `bash').
+This can be done from your `.login' or `.profile' file, once and for
+all.
+
+   You might think that the country code specification is redundant.
+But in fact, some languages have dialects in different countries.  For
+example, `de_AT' is used for Austria, and `pt_BR' for Brazil.  The
+country code serves to distinguish the dialects.
+
+   The locale naming convention of `LL_CC', with `LL' denoting the
+language and `CC' denoting the country, is the one use on systems based
+on GNU libc.  On other systems, some variations of this scheme are
+used, such as `LL' or `LL_CC.ENCODING'.  You can get the list of
+locales supported by your system for your language by running the
+command `locale -a | grep '^LL''.
+
+   Not all programs have translations for all languages.  By default, an
+English message is shown in place of a nonexistent translation.  If you
+understand other languages, you can set up a priority list of languages.
+This is done through a different environment variable, called
+`LANGUAGE'.  GNU `gettext' gives preference to `LANGUAGE' over `LANG'
+for the purpose of message handling, but you still need to have `LANG'
+set to the primary language; this is required by other parts of the
+system libraries.  For example, some Swedish users who would rather
+read translations in German than English for when Swedish is not
+available, set `LANGUAGE' to `sv:de' while leaving `LANG' to `sv_SE'.
+
+   Special advice for Norwegian users: The language code for Norwegian
+bokma*l changed from `no' to `nb' recently (in 2003).  During the
+transition period, while some message catalogs for this language are
+installed under `nb' and some older ones under `no', it's recommended
+for Norwegian users to set `LANGUAGE' to `nb:no' so that both newer and
+older translations are used.
+
+   In the `LANGUAGE' environment variable, but not in the `LANG'
+environment variable, `LL_CC' combinations can be abbreviated as `LL'
+to denote the language's main dialect.  For example, `de' is equivalent
+to `de_DE' (German as spoken in Germany), and `pt' to `pt_PT'
+(Portuguese as spoken in Portugal) in this context.
+
+1.4 Translating Teams
+=====================
+
+For the Free Translation Project to be a success, we need interested
+people who like their own language and write it well, and who are also
+able to synergize with other translators speaking the same language.
+Each translation team has its own mailing list.  The up-to-date list of
+teams can be found at the Free Translation Project's homepage,
+`http://translationproject.org/', in the "Teams" area.
+
+   If you'd like to volunteer to _work_ at translating messages, you
+should become a member of the translating team for your own language.
+The subscribing address is _not_ the same as the list itself, it has
+`-request' appended.  For example, speakers of Swedish can send a
+message to `sv-request@li.org', having this message body:
+
+     subscribe
+
+   Keep in mind that team members are expected to participate
+_actively_ in translations, or at solving translational difficulties,
+rather than merely lurking around.  If your team does not exist yet and
+you want to start one, or if you are unsure about what to do or how to
+get started, please write to `coordinator@translationproject.org' to
+reach the coordinator for all translator teams.
+
+   The English team is special.  It works at improving and uniformizing
+the terminology in use.  Proven linguistic skills are praised more than
+programming skills, here.
+
+1.5 Available Packages
+======================
+
+Languages are not equally supported in all packages.  The following
+matrix shows the current state of internationalization, as of November
+2007.  The matrix shows, in regard of each package, for which languages
+PO files have been submitted to translation coordination, with a
+translation percentage of at least 50%.

+   Some counters in the preceding matrix are higher than the number of

+used for implementing regional variants of languages, or language
+dialects.
+
+   For a PO file in the matrix above to be effective, the package to
+which it applies should also have been internationalized and
+distributed as such by its maintainer.  There might be an observable
+lag between the mere existence a PO file and its wide availability in a
+distribution.

+
+1.6 Using `gettext' in new packages
+===================================
+
+If you are writing a freely available program and want to
+internationalize it you are welcome to use GNU `gettext' in your
+package.  Of course you have to respect the GNU Library General Public
+License which covers the use of the GNU `gettext' library.  This means
+in particular that even non-free programs can use `libintl' as a shared
+library, whereas only free software can use `libintl' as a static
+library or use modified versions of `libintl'.
+
+   Once the sources are changed appropriately and the setup can handle
+the use of `gettext' the only thing missing are the translations.  The
+Free Translation Project is also available for packages which are not
+developed inside the GNU project.  Therefore the information given above
+applies also for every other Free Software Project.  Contact
+`coordinator@translationproject.org' to make the `.pot' files available
+to the translation teams.

+* ABOUT BUGS
+
+Before reporting a bug, please check the list of known bugs
+and the list of oft-reported non-bugs (below).
+
+Bugs and comments may be sent to bonzini@gnu.org; please
+include in the Subject: header the first line of the output of
+``sed --version''.
+
+Please do not send a bug report like this:
+
+	[while building frobme-1.3.4] 
+	$ configure 
+	sed: file sedscr line 1: Unknown option to 's'
+
+If sed doesn't configure your favorite package, take a few extra
+minutes to identify the specific problem and make a stand-alone test
+case.
+
+A stand-alone test case includes all the data necessary to perform the
+test, and the specific invocation of sed that causes the problem.  The
+smaller a stand-alone test case is, the better.  A test case should
+not involve something as far removed from sed as ``try to configure
+frobme-1.3.4''.  Yes, that is in principle enough information to look
+for the bug, but that is not a very practical prospect.
+
+
+
+* NON-BUGS
+
+`N' command on the last line
+
+  Most versions of sed exit without printing anything when the `N'
+  command is issued on the last line of a file.  GNU sed instead
+  prints pattern space before exiting unless of course the `-n'
+  command switch has been specified.  More information on the reason
+  behind this choice can be found in the Info manual.
+
+
+regex syntax clashes (problems with backslashes)
+
+  sed uses the Posix basic regular expression syntax.  According to
+  the standard, the meaning of some escape sequences is undefined in
+  this syntax;  notable in the case of GNU sed are `\|', `\+', `\?',
+  `\`', `\'', `\<', `\>', `\b', `\B', `\w', and `\W'.
+
+  As in all GNU programs that use Posix basic regular expressions, sed
+  interprets these escape sequences as meta-characters.  So, `x\+'
+  matches one or more occurrences of `x'.   `abc\|def' matches either
+  `abc' or `def'.
+
+  This syntax may cause problems when running scripts written for other
+  seds.  Some sed programs have been written with the assumption that
+  `\|' and `\+' match the literal characters `|' and `+'.  Such scripts
+  must be modified by removing the spurious backslashes if they are to
+  be used with recent versions of sed (not only GNU sed).
+
+  On the other hand, some scripts use `s|abc\|def||g' to remove occurrences
+  of _either_ `abc' or `def'.  While this worked until sed 4.0.x, newer
+  versions interpret this as removing the string `abc|def'.  This is
+  again undefined behavior according to POSIX, but this interpretation
+  is arguably more robust: the older one, for example, required that
+  the regex matcher parsed `\/' as `/' in the common case of escaping
+  a slash, which is again undefined behavior; the new behavior avoids
+  this, and this is good because the regex matcher is only partially
+  under our control.
+
+  In addition, GNU sed supports several escape characters (some of
+  which are multi-character) to insert non-printable characters
+  in scripts (`\a', `\c', `\d', `\o', `\r', `\t', `\v', `\x').  These
+  can cause similar problems with scripts written for other seds.
+
+
+-i clobbers read-only files
+
+  In short, `sed d -i' will let one delete the contents of
+  a read-only file, and in general the `-i' option will let
+  one clobber protected files.  This is not a bug, but rather a
+  consequence of how the Unix filesystem works.
+
+  The permissions on a file say what can happen to the data
+  in that file, while the permissions on a directory say what can
+  happen to the list of files in that directory.  `sed -i'
+  will not ever open for writing  a file that is already on disk,
+  rather, it will work on a temporary file that is finally renamed
+  to the original name: if you rename or delete files, you're actually
+  modifying the contents of the directory, so the operation depends on
+  the permissions of the directory, not of the file).  For this same
+  reason, sed will not let one use `-i' on a writeable file in a
+  read-only directory, and will break hard or symbolic links when
+  `-i' is used on such a file.
+
+
+`0a' does not work (gives an error)
+
+  There is no line 0.  0 is a special address that is only used to treat
+  addresses like `0,/RE/' as active when the script starts: if you
+  write `1,/abc/d' and the first line includes the word `abc', then
+  that match would be ignored because address ranges must span at least
+  two lines (barring the end of the file); but what you probably wanted is
+  to delete every line up to the first one including `abc', and this
+  is obtained with `0,/abc/d'.
+
+
+`[a-z]' is case insensitive
+`s/.*//' does not clear pattern space
+
+  You are encountering problems with locales.  POSIX mandates that `[a-z]'
+  uses the current locale's collation order -- in C parlance, that means
+  strcoll(3) instead of strcmp(3).  Some locales have a case insensitive
+  strcoll, others don't.
+
+  Another problem is that [a-z] tries to use collation symbols.  This
+  only happens if you are on the GNU system, using GNU libc's regular
+  expression matcher instead of compiling the one supplied with GNU sed.
+  In a Danish locale, for example, the regular expression `^[a-z]$'
+  matches the string `aa', because `aa' is a single collating symbol that
+  comes after `a' and before `b'; `ll' behaves similarly in Spanish
+  locales, or `ij' in Dutch locales.
+
+  Another common localization-related problem happens if your input stream
+  includes invalid multibyte sequences.  POSIX mandates that such
+  sequences are _not_ matched by `.', so that `s/.*//' will not clear
+  pattern space as you would expect.  In fact, there is no way to clear
+  sed's buffers in the middle of the script in most multibyte locales
+  (including UTF-8 locales).  For this reason, GNU sed provides a `z'
+  command (for `zap') as an extension.
+
+  However, to work around both of these problems, which may cause bugs
+  in shell scripts, you can set the LC_ALL environment variable to `C',
+  or set the locale on a more fine-grained basis with the other LC_*
+  environment variables.

+		    GNU GENERAL PUBLIC LICENSE
+		       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+ 
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+  
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+		     END OF TERMS AND CONDITIONS
+
+	    How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+
+
+ Copyright (C) 2000, 2001, 2002, 2007, 2008 Free Software Foundation, Inc.
+     <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+0. PREAMBLE
+
+The purpose of this License is to make a manual, textbook, or other
+functional and useful document "free" in the sense of freedom: to
+assure everyone the effective freedom to copy and redistribute it,
+with or without modifying it, either commercially or noncommercially.
+Secondarily, this License preserves for the author and publisher a way
+to get credit for their work, while not being considered responsible
+for modifications made by others.
+
+This License is a kind of "copyleft", which means that derivative
+works of the document must themselves be free in the same sense.  It
+complements the GNU General Public License, which is a copyleft
+license designed for free software.
+
+We have designed this License in order to use it for manuals for free
+software, because free software needs free documentation: a free
+program should come with manuals providing the same freedoms that the
+software does.  But this License is not limited to software manuals;
+it can be used for any textual work, regardless of subject matter or
+whether it is published as a printed book.  We recommend this License
+principally for works whose purpose is instruction or reference.
+
+
+1. APPLICABILITY AND DEFINITIONS
+
+This License applies to any manual or other work, in any medium, that
+contains a notice placed by the copyright holder saying it can be
+distributed under the terms of this License.  Such a notice grants a
+world-wide, royalty-free license, unlimited in duration, to use that
+work under the conditions stated herein.  The "Document", below,
+refers to any such manual or work.  Any member of the public is a
+licensee, and is addressed as "you".  You accept the license if you
+copy, modify or distribute the work in a way requiring permission
+under copyright law.
+
+A "Modified Version" of the Document means any work containing the
+Document or a portion of it, either copied verbatim, or with
+modifications and/or translated into another language.
+
+A "Secondary Section" is a named appendix or a front-matter section of
+the Document that deals exclusively with the relationship of the
+publishers or authors of the Document to the Document's overall
+subject (or to related matters) and contains nothing that could fall
+directly within that overall subject.  (Thus, if the Document is in
+part a textbook of mathematics, a Secondary Section may not explain
+any mathematics.)  The relationship could be a matter of historical
+connection with the subject or with related matters, or of legal,
+commercial, philosophical, ethical or political position regarding
+them.
+
+The "Invariant Sections" are certain Secondary Sections whose titles
+are designated, as being those of Invariant Sections, in the notice
+that says that the Document is released under this License.  If a
+section does not fit the above definition of Secondary then it is not
+allowed to be designated as Invariant.  The Document may contain zero
+Invariant Sections.  If the Document does not identify any Invariant
+Sections then there are none.
+
+The "Cover Texts" are certain short passages of text that are listed,
+as Front-Cover Texts or Back-Cover Texts, in the notice that says that
+the Document is released under this License.  A Front-Cover Text may
+be at most 5 words, and a Back-Cover Text may be at most 25 words.
+
+A "Transparent" copy of the Document means a machine-readable copy,
+represented in a format whose specification is available to the
+general public, that is suitable for revising the document
+straightforwardly with generic text editors or (for images composed of
+pixels) generic paint programs or (for drawings) some widely available
+drawing editor, and that is suitable for input to text formatters or
+for automatic translation to a variety of formats suitable for input
+to text formatters.  A copy made in an otherwise Transparent file
+format whose markup, or absence of markup, has been arranged to thwart
+or discourage subsequent modification by readers is not Transparent.
+An image format is not Transparent if used for any substantial amount
+of text.  A copy that is not "Transparent" is called "Opaque".
+
+Examples of suitable formats for Transparent copies include plain
+ASCII without markup, Texinfo input format, LaTeX input format, SGML
+or XML using a publicly available DTD, and standard-conforming simple
+HTML, PostScript or PDF designed for human modification.  Examples of
+transparent image formats include PNG, XCF and JPG.  Opaque formats
+include proprietary formats that can be read and edited only by
+proprietary word processors, SGML or XML for which the DTD and/or
+processing tools are not generally available, and the
+machine-generated HTML, PostScript or PDF produced by some word
+processors for output purposes only.
+
+The "Title Page" means, for a printed book, the title page itself,
+plus such following pages as are needed to hold, legibly, the material
+this License requires to appear in the title page.  For works in
+formats which do not have any title page as such, "Title Page" means
+the text near the most prominent appearance of the work's title,
+preceding the beginning of the body of the text.
+
+The "publisher" means any person or entity that distributes copies of
+the Document to the public.
+
+A section "Entitled XYZ" means a named subunit of the Document whose
+title either is precisely XYZ or contains XYZ in parentheses following
+text that translates XYZ in another language.  (Here XYZ stands for a
+specific section name mentioned below, such as "Acknowledgements",
+"Dedications", "Endorsements", or "History".)  To "Preserve the Title"
+of such a section when you modify the Document means that it remains a
+section "Entitled XYZ" according to this definition.
+
+The Document may include Warranty Disclaimers next to the notice which
+states that this License applies to the Document.  These Warranty
+Disclaimers are considered to be included by reference in this
+License, but only as regards disclaiming warranties: any other
+implication that these Warranty Disclaimers may have is void and has
+no effect on the meaning of this License.
+
+2. VERBATIM COPYING
+
+You may copy and distribute the Document in any medium, either
+commercially or noncommercially, provided that this License, the
+copyright notices, and the license notice saying this License applies
+to the Document are reproduced in all copies, and that you add no
+other conditions whatsoever to those of this License.  You may not use
+technical measures to obstruct or control the reading or further
+copying of the copies you make or distribute.  However, you may accept
+compensation in exchange for copies.  If you distribute a large enough
+number of copies you must also follow the conditions in section 3.
+
+You may also lend copies, under the same conditions stated above, and
+you may publicly display copies.
+
+
+3. COPYING IN QUANTITY
+
+If you publish printed copies (or copies in media that commonly have
+printed covers) of the Document, numbering more than 100, and the
+Document's license notice requires Cover Texts, you must enclose the
+copies in covers that carry, clearly and legibly, all these Cover
+Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
+the back cover.  Both covers must also clearly and legibly identify
+you as the publisher of these copies.  The front cover must present
+the full title with all words of the title equally prominent and
+visible.  You may add other material on the covers in addition.
+Copying with changes limited to the covers, as long as they preserve
+the title of the Document and satisfy these conditions, can be treated
+as verbatim copying in other respects.
+
+If the required texts for either cover are too voluminous to fit
+legibly, you should put the first ones listed (as many as fit
+reasonably) on the actual cover, and continue the rest onto adjacent
+pages.
+
+If you publish or distribute Opaque copies of the Document numbering
+more than 100, you must either include a machine-readable Transparent
+copy along with each Opaque copy, or state in or with each Opaque copy
+a computer-network location from which the general network-using
+public has access to download using public-standard network protocols
+a complete Transparent copy of the Document, free of added material.
+If you use the latter option, you must take reasonably prudent steps,
+when you begin distribution of Opaque copies in quantity, to ensure
+that this Transparent copy will remain thus accessible at the stated
+location until at least one year after the last time you distribute an
+Opaque copy (directly or through your agents or retailers) of that
+edition to the public.
+
+It is requested, but not required, that you contact the authors of the
+Document well before redistributing any large number of copies, to
+give them a chance to provide you with an updated version of the
+Document.
+
+
+4. MODIFICATIONS
+
+You may copy and distribute a Modified Version of the Document under
+the conditions of sections 2 and 3 above, provided that you release
+the Modified Version under precisely this License, with the Modified
+Version filling the role of the Document, thus licensing distribution
+and modification of the Modified Version to whoever possesses a copy
+of it.  In addition, you must do these things in the Modified Version:
+
+A. Use in the Title Page (and on the covers, if any) a title distinct
+   from that of the Document, and from those of previous versions
+   (which should, if there were any, be listed in the History section
+   of the Document).  You may use the same title as a previous version
+   if the original publisher of that version gives permission.
+B. List on the Title Page, as authors, one or more persons or entities
+   responsible for authorship of the modifications in the Modified
+   Version, together with at least five of the principal authors of the
+   Document (all of its principal authors, if it has fewer than five),
+   unless they release you from this requirement.
+C. State on the Title page the name of the publisher of the
+   Modified Version, as the publisher.
+D. Preserve all the copyright notices of the Document.
+E. Add an appropriate copyright notice for your modifications
+   adjacent to the other copyright notices.
+F. Include, immediately after the copyright notices, a license notice
+   giving the public permission to use the Modified Version under the
+   terms of this License, in the form shown in the Addendum below.
+G. Preserve in that license notice the full lists of Invariant Sections
+   and required Cover Texts given in the Document's license notice.
+H. Include an unaltered copy of this License.
+I. Preserve the section Entitled "History", Preserve its Title, and add
+   to it an item stating at least the title, year, new authors, and
+   publisher of the Modified Version as given on the Title Page.  If
+   there is no section Entitled "History" in the Document, create one
+   stating the title, year, authors, and publisher of the Document as
+   given on its Title Page, then add an item describing the Modified
+   Version as stated in the previous sentence.
+J. Preserve the network location, if any, given in the Document for
+   public access to a Transparent copy of the Document, and likewise
+   the network locations given in the Document for previous versions
+   it was based on.  These may be placed in the "History" section.
+   You may omit a network location for a work that was published at
+   least four years before the Document itself, or if the original
+   publisher of the version it refers to gives permission.
+K. For any section Entitled "Acknowledgements" or "Dedications",
+   Preserve the Title of the section, and preserve in the section all
+   the substance and tone of each of the contributor acknowledgements
+   and/or dedications given therein.
+L. Preserve all the Invariant Sections of the Document,
+   unaltered in their text and in their titles.  Section numbers
+   or the equivalent are not considered part of the section titles.
+M. Delete any section Entitled "Endorsements".  Such a section
+   may not be included in the Modified Version.
+N. Do not retitle any existing section to be Entitled "Endorsements"
+   or to conflict in title with any Invariant Section.
+O. Preserve any Warranty Disclaimers.
+
+If the Modified Version includes new front-matter sections or
+appendices that qualify as Secondary Sections and contain no material
+copied from the Document, you may at your option designate some or all
+of these sections as invariant.  To do this, add their titles to the
+list of Invariant Sections in the Modified Version's license notice.
+These titles must be distinct from any other section titles.
+
+You may add a section Entitled "Endorsements", provided it contains
+nothing but endorsements of your Modified Version by various
+parties--for example, statements of peer review or that the text has
+been approved by an organization as the authoritative definition of a
+standard.
+
+You may add a passage of up to five words as a Front-Cover Text, and a
+passage of up to 25 words as a Back-Cover Text, to the end of the list
+of Cover Texts in the Modified Version.  Only one passage of
+Front-Cover Text and one of Back-Cover Text may be added by (or
+through arrangements made by) any one entity.  If the Document already
+includes a cover text for the same cover, previously added by you or
+by arrangement made by the same entity you are acting on behalf of,
+you may not add another; but you may replace the old one, on explicit
+permission from the previous publisher that added the old one.
+
+The author(s) and publisher(s) of the Document do not by this License
+give permission to use their names for publicity for or to assert or
+imply endorsement of any Modified Version.
+
+
+5. COMBINING DOCUMENTS
+
+You may combine the Document with other documents released under this
+License, under the terms defined in section 4 above for modified
+versions, provided that you include in the combination all of the
+Invariant Sections of all of the original documents, unmodified, and
+list them all as Invariant Sections of your combined work in its
+license notice, and that you preserve all their Warranty Disclaimers.
+
+The combined work need only contain one copy of this License, and
+multiple identical Invariant Sections may be replaced with a single
+copy.  If there are multiple Invariant Sections with the same name but
+different contents, make the title of each such section unique by
+adding at the end of it, in parentheses, the name of the original
+author or publisher of that section if known, or else a unique number.
+Make the same adjustment to the section titles in the list of
+Invariant Sections in the license notice of the combined work.
+
+In the combination, you must combine any sections Entitled "History"
+in the various original documents, forming one section Entitled
+"History"; likewise combine any sections Entitled "Acknowledgements",
+and any sections Entitled "Dedications".  You must delete all sections
+Entitled "Endorsements".
+
+
+6. COLLECTIONS OF DOCUMENTS
+
+You may make a collection consisting of the Document and other
+documents released under this License, and replace the individual
+copies of this License in the various documents with a single copy
+that is included in the collection, provided that you follow the rules
+of this License for verbatim copying of each of the documents in all
+other respects.
+
+You may extract a single document from such a collection, and
+distribute it individually under this License, provided you insert a
+copy of this License into the extracted document, and follow this
+License in all other respects regarding verbatim copying of that
+document.
+
+
+7. AGGREGATION WITH INDEPENDENT WORKS
+
+A compilation of the Document or its derivatives with other separate
+and independent documents or works, in or on a volume of a storage or
+distribution medium, is called an "aggregate" if the copyright
+resulting from the compilation is not used to limit the legal rights
+of the compilation's users beyond what the individual works permit.
+When the Document is included in an aggregate, this License does not
+apply to the other works in the aggregate which are not themselves
+derivative works of the Document.
+
+If the Cover Text requirement of section 3 is applicable to these
+copies of the Document, then if the Document is less than one half of
+the entire aggregate, the Document's Cover Texts may be placed on
+covers that bracket the Document within the aggregate, or the
+electronic equivalent of covers if the Document is in electronic form.
+Otherwise they must appear on printed covers that bracket the whole
+aggregate.
+
+
+8. TRANSLATION
+
+Translation is considered a kind of modification, so you may
+distribute translations of the Document under the terms of section 4.
+Replacing Invariant Sections with translations requires special
+permission from their copyright holders, but you may include
+translations of some or all Invariant Sections in addition to the
+original versions of these Invariant Sections.  You may include a
+translation of this License, and all the license notices in the
+Document, and any Warranty Disclaimers, provided that you also include
+the original English version of this License and the original versions
+of those notices and disclaimers.  In case of a disagreement between
+the translation and the original version of this License or a notice
+or disclaimer, the original version will prevail.
+
+If a section in the Document is Entitled "Acknowledgements",
+"Dedications", or "History", the requirement (section 4) to Preserve
+its Title (section 1) will typically require changing the actual
+title.
+
+
+9. TERMINATION
+
+You may not copy, modify, sublicense, or distribute the Document
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense, or distribute it is void, and
+will automatically terminate your rights under this License.
+
+However, if you cease all violation of this License, then your license
+from a particular copyright holder is reinstated (a) provisionally,
+unless and until the copyright holder explicitly and finally
+terminates your license, and (b) permanently, if the copyright holder
+fails to notify you of the violation by some reasonable means prior to
+60 days after the cessation.
+
+Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, receipt of a copy of some or all of the same material does
+not give you any rights to use it.
+
+
+10. FUTURE REVISIONS OF THIS LICENSE
+
+The Free Software Foundation may publish new, revised versions of the
+GNU Free Documentation License from time to time.  Such new versions
+will be similar in spirit to the present version, but may differ in
+detail to address new problems or concerns.  See
+http://www.gnu.org/copyleft/.
+
+Each version of the License is given a distinguishing version number.
+If the Document specifies that a particular numbered version of this
+License "or any later version" applies to it, you have the option of
+following the terms and conditions either of that specified version or
+of any later version that has been published (not as a draft) by the
+Free Software Foundation.  If the Document does not specify a version
+number of this License, you may choose any version ever published (not
+as a draft) by the Free Software Foundation.  If the Document
+specifies that a proxy can decide which future versions of this
+License can be used, that proxy's public statement of acceptance of a
+version permanently authorizes you to choose that version for the
+Document.
+
+11. RELICENSING
+
+"Massive Multiauthor Collaboration Site" (or "MMC Site") means any
+World Wide Web server that publishes copyrightable works and also
+provides prominent facilities for anybody to edit those works.  A
+public wiki that anybody can edit is an example of such a server.  A
+"Massive Multiauthor Collaboration" (or "MMC") contained in the site
+means any set of copyrightable works thus published on the MMC site.
+
+"CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0 
+license published by Creative Commons Corporation, a not-for-profit 
+corporation with a principal place of business in San Francisco, 
+California, as well as future copyleft versions of that license 
+published by that same organization.
+
+"Incorporate" means to publish or republish a Document, in whole or in 
+part, as part of another Document.
+
+An MMC is "eligible for relicensing" if it is licensed under this 
+License, and if all works that were first published under this License 
+somewhere other than this MMC, and subsequently incorporated in whole or 
+in part into the MMC, (1) had no cover texts or invariant sections, and 
+(2) were thus incorporated prior to November 1, 2008.
+
+The operator of an MMC Site may republish an MMC contained in the site
+under CC-BY-SA on the same site at any time before August 1, 2009,
+provided the MMC is eligible for relicensing.
+
+
+ADDENDUM: How to use this License for your documents
+
+To use this License in a document you have written, include a copy of
+the License in the document and put the following copyright and
+license notices just after the title page:
+
+    Copyright (c)  YEAR  YOUR NAME.
+    Permission is granted to copy, distribute and/or modify this document
+    under the terms of the GNU Free Documentation License, Version 1.3
+    or any later version published by the Free Software Foundation;
+    with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts.
+    A copy of the license is included in the section entitled "GNU
+    Free Documentation License".
+
+If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
+replace the "with...Texts." line with this:
+
+    with the Invariant Sections being LIST THEIR TITLES, with the
+    Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST.
+
+If you have Invariant Sections without Cover Texts, or some other
+combination of the three, merge those two alternatives to suit the
+situation.
+
+If your document contains nontrivial examples of program code, we
+recommend releasing these examples in parallel under your choice of
+free software license, such as the GNU General Public License,
+to permit their use in free software.

+
+	Change the way we treat lines which are not terminated by a newline.
+	Such lines are printed without the terminating newline (as before)
+	but as soon as more text is sent to the same output stream, the
+	missing newline is printed, so that the two lines don't concatenate.

+	line.
+	(execute_program): Commands `c' and `i' no longer call the
+	function output_line with chomped==FALSE; instead, they chomp
+	the text and call the function with chomped==TRUE.
+	(execute_program): Command `e' no longer uses output_line; it
+	calls ck_fwrite directly.  Commands `e', `L' and `=' flush
+	the output stream at the end.
+	* sed/compile.c (special_files): Use `struct output' instead of the
+	file name.
+	(get_openfile): ... special files are no longer copied to file_read

+
+2001-11-09  Paolo Bonzini  <bonzini@gnu.org>

+
+	* sed/compile.c (compile_program): Compile command `e'
+	like `c'.

+
+2001-09-05  Paolo Bonzini  <bonzini@gnu.org>
+
+	* sed/execute.c (do_subst): `baaac', if passed through
+	s/a*/x/g, gave `xbxxcx' rather than `xbxcx' (because an
+	empty string matched before the `c'.  Fixed.
+
+	* sed/execute.c: Removed mmap support, I/O is done using
+	getline (slower but more bug-proof).
+	* sed/utils.c: Likewise.

+
+2001-02-08  Paolo Bonzini  <bonzini@gnu.org>

+	* sed/execute.c (execute_program): Ditto
+
+	* sed/compile.c (compile_program): Fill in exit_status for `q' and `Q'
+	* sed/execute.c (execute_program): Return -1 for `go on', 0..255

+
+2001-01-04  Paolo Bonzini  <bonzini@gnu.org>
+
+	* testsuite/Makefile.am: Use automake's implementation
+	of `make check'.  Removed the test targets
+	* testsuite/Makefile.tests: Moved the test targets here
+	(new file).
+	* testsuite/runtest: New file
+
+	* testsuite/Makefile.tests: `khadafy' test uses EREs.
+
+	* testsuite/spencer.inp: Removed the ^* test

+	extended_regexp_flags to support Perl regular expressions.
+
+	* sed/execute.c(open_next_file): Don't mmap stdin (because
+	we cannot seek into it, so a redirected stdin's contents
+	would not be "eaten" by sed)
+
+Mon Aug 30 23:40:08 PDT 1999  Ken Pizzini <ken@gnu.org>
+
+	*** Version 3.02.80 released
+	
+	* sed/execute.c(do_subst): lib/regex.c(re_search_2) seems to
+	want one extra backreference register; humor it.
+
+	* sed/regex.c(compile_regex): work around some odd assumptions
+	that lib/regex.c(re_compile_pattern) makes about our desired
+	RE syntax.
+
+	* configure.in: tweaked version to 3.02.80; added new entries
+	to the ALL_LINGUAS definition.
+
+	* doc/sed.1, doc/sed.texi, BUGS: explicitly request the output
+	of sed --version in bug-reporting instructions.
+
+	* doc/sed.texi: the old "informal seders list" is dead; document
+	the new sed-users mailing list instead (under Other Resources).
+
+
+Thu Aug 19 23:27:54 PDT 1999  Ken Pizzini <ken@gnu.org>
+	
+	* sed/sed.h: Add explicit #include of "regex-sed.h" (rather
+	 than relying on parent file doing so); change the "cmd_regex"
+	 member of sed_cmd: make it a pointer (instead of a struct),
+	 and change its name to cmd_subst; add prototypes for newly
+	 exported functions bad_prog(), normalize_text(), compile_regex(),
+	 match_regex(), and release_regex(); drop rx_testing variable.
+
+	* sed/compile.c: move the compile_regex() function to regex.c;
+	export bad_prog() and normalize_text() functions; eliminate the
+	rx_testing debris; rename the NOLEAKS symbol to more descriptive
+	DEBUG_LEAKS; make cmd_regex to cmd_subst fixes (see above);
+	make use of newly abstracted release_regex() function.
+
+	* sed/execute.c: abstract out the regex matching to
+	regex.c:match_regex(); NOLEAKS to DEBUG_LEAKS change;
+	cmd_regex to cmd_subst structure member name change.
+
+	* sed/execute.c(do_subst): use re_registers/regoff_t instead of
+	regmatch_t to hold the backreference registers, make "offset"
+	always be relative to the beginning of the string (rather than
+	a delta from "start"), defer some matching bookkeeping (e.g.,
+	not_bol_p) to match_regex().
+
+	* sed/sed.c(main): loose rx_testing variable; NOLEAKS
+	(aka DEBUG_LEAKS) code attempting to release
+	_nl_current_default_domain is problematic, so omit it.
+
+	* sed/regex.c: new file --- abstracts out the interface to the
+	regex engine so that less conditional code is required in
+	compile.c and execute.c, and so as to make a change of engine
+	easier; implements compile_regex() (which looks an awful lot
+	like the one that used to live in compile.c), match_regex(),
+	and (if DEBUG_LEAKS is set) release_regex().
+
+Sun Apr 18 04:40:46 PDT 1999  Ken Pizzini <ken@gnu.org>
+
+	* sed/sed.c(main): conditionalize calls to setlocale() and
+	textdomain() to only occur if their support is needed/wanted.
+
+Sun Apr 18 03:01:46 PDT 1999  Ken Pizzini <ken@gnu.org>
+
+	* bootstrap.sh: "foo || bar && baz" was not grouping like I
+	expected ("foo || (bar && baz)") under at least one shell,
+	so change the test for a pre-existing config.h file to an
+	if statement.
+
+	* bootstrap.sh: added -DUSE_REGEX_GNU_H option to the
+	compiler invocation, to ensure that we get a usable
+	regex library included.
+
+Sun Apr 18 02:59:42 PDT 1999  Ken Pizzini <ken@gnu.org>
+
+	* sed/sed.h, sed/utils.c: conditionalized inclusion of <libintl.h>
+	to occur only if ENABLE_NLS is defined.
+
+Sun Apr 18 01:48:45 PDT 1999  Ken Pizzini <ken@gnu.org>
+
+	* sed/compile.c(xofa,normalize_text,convert_number): change
+	name of xofa() function to convert_number(); change semantics
+	to do all of the work of the text->number conversion.
+
+	* sed/compile.c(normalize_text): add new \dDDD decimal
+	and \oOOO octal escapes.
+
+Sun Mar 28 21:05:07 PST 1999  Ken Pizzini <ken@gnu.org>
+
+	* sed/sed.c(main): if NOLEAKS is set, free up a word that
+	the call to textdomain() allocated.
+
+	* sed/execute.c(read_file_line): plug up (minor) memory leak:
+	if buffer.alloc==0 we may have malloc()'d 1 byte anyway,
+	so be sure to FREE(buffer.text) before calling line_init();
+
+Fri Mar 26 16:52:10 PST 1999  Ken Pizzini <ken@gnu.org>
+
+	* sed/compile.c(match_slash): somewhere between 3.02
+	and 3.02a we lost the ability to use a newline as
+	the s/// delimiter; restore this ability.
+
+	* sed/compile.c(compile_regex): forget about trying
+	to cache the compiled form of the last RE --- it
+	causes more problems than its worth.  We now only
+	cache the source form.
+
+	* testsuite/help.good: update to reflect output containing
+	new options.
+
+Sun Dec  6 00:51:23 PST 1998  Ken Pizzini <ken@gnu.org>
+
+	* sed/utils.c(ck_fwrite): fix i18n bug of using a printf
+	fragment of "item%s" to handle plural text.
+
+Mon Nov 23 11:03:40 PST 1998  Ken Pizzini <ken@gnu.org>
+
+	* doc/sed.1, doc/sed.texi: ran ispell over these
+	files to catch the more obvious typos...
+
+Sun Nov  1 00:09:07 PST 1998  Ken Pizzini <ken@gnu.org>
+
+	* sed/execute.c(do_list): make a `lcmd_out_line_len'
+	(--line-length) of zero mean "infinite length",
+	i.e., "never wrap".
+
+Sat Oct 31 23:06:50 PST 1998  Ken Pizzini <ken@gnu.org>
+
+	* execute.c(match_an_address_p,process_files),
+	compile.c(compile_program): back out the "zero-address"
+	changes of 1998-09-27.  It was a neat idea, but there are
+	too many dark corners which don't work well.  The
+	special code for handling line ranges starting at
+	address zero (from 1998-08-31) are still there though:
+	this seems to work fine with no surprises.
+
+Sat Oct 31 22:18:59 PST 1998  Ken Pizzini <ken@gnu.org>
+
+	* sed/sed.c, sed/sed.h, sed/execute.c: added new
+	`lcmd_out_line_len' variable.  (Idea suggested by
+	Carlos J. G. Duarte <l38076@alfa.ist.utl.pt>.)
+	Also added ATOI macro (which uses strtoul() if available,
+	with fall-back to atoi()).
+	* sed/sed.c(main): attempt to use COLS environment variable
+	to set a reasonable `lcmd_out_line_len'; added -l/--line-length
+	command-line options to set the new `lcmd_out_line_len' flag.
+	* sed/sed.c(usage): documented new -l/--line-length options.
+	* sed/execute.c(do_list): use `lcmd_out_line_len' variable
+	instead of `LCMD_OUT_LINE_LEN'.
+	* sed/execute.c: deleted now obsolete LCMD_OUT_LINE_LEN define.
+	* configure.in: added strtoul to the AC_CHECK_FUNCS call.
+
+Sat Oct 31 21:37:17 PST 1998  Ken Pizzini <ken@gnu.org>
+
+	* sed/sed.c, sed/sed.h, sed/execute.c: added new `force_unbuffered'
+	flag.  (Idea suggested by Frank Strauss <strauss@escape.de>.)
+	* sed/sed.c(main): added -u/--unbuffered command-line options
+	to set the new `force_unbuffered' flag.
+	* sed/sed.c(usage): documented new -u/--unbuffered options.
+	* sed/execute.c: changed the name of the `is_tty' flag in struct
+	input to a more generic `no_buffering'; also removed HAVE_ISATTY
+	conditional on this member.
+	* sed/execute.c(slow_getline): removed HAVE_ISATTY conditonal
+	compilation of this function.
+	* sed/execute.c(output_line): if force_unbuffered is set,
+	then force a fflush() even if writing to stdout.
+	* sed/execute.c(open_next_file): added handling of the
+	new `force_unbuffered' flag so that slow_getline()
+	will always be used for input.
+	* sed/execute.c(read_file_line): changed the (conditionally
+	compiled) test of `input->is_tty' to (unconditionally)
+	use the new spelling `input->no_buffering'.
+
+Thu Oct 15 12:08:09 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	* configure.in: deleted AC_ARG_PROGRAM call; this is already
+	done for us by AM_INIT_AUTOMAKE, and we were winding up
+	with a doubled-transform.
+
+Sun Sep 27 01:42:42 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	* compile.c(compile_program): remove special-case code for matching
+	address range with a `0' beginning.
+
+	* compile.c(compile_address): change default addr_number to
+	be a pragmatically impossible countT value, instead of zero.
+
+	* execute.c: spell macro REGNEXEC() unconditionally instead of
+	playing with conditional definition of regnexec() macro.
+
+	* execute.c(match_an_address_p): added third argument (and changed
+	callers in match_address_p).  Added special code to ignore
+	non-numeric matches when processing "line zero".
+
+	* execute.c(process_files): added a "line zero" pass through the
+	commands script.
+
+Sun Sep 27 00:20:53 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	* compile.c(xofa,normalize_text): new functions.
+	* compile.c(compile_regex): cache last_compiled_re (with its
+	associated flags); add POSIXLY_CORRECT behavior for empty RE.
+	Make use of the new normalize_text() function.
+	* compile.c(setup_replacement): Make use of the new normalize_text()
+	function.
+
+Sat Sep 26 22:59:13 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	* lib/regex-gnu.h: added missing prototype for regncomp().
+
+Mon Sep 14 20:47:23 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	* sed/sed.c(main): use EXIT_SUCCESS instead of 0, in case
+	we are built on a system (such as VMS) where EXIT_SUCCESS
+	is distinct from 0.
+
+Wed Sep  9 22:17:28 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	* sed/Makefile.am: added -I../intl the INCLUDES line; if we are
+	building in a directory outside the source tree and the system
+	we are building on does not have a <libintl.h> header, then
+	the build was failing, because libintl.h is a build-time
+	constructed source file.
+
+	* configure.in: tweaked version to be 3.02b.
+
+Wed Sep  9 19:28:14 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	*** Version 3.02a released
+	
+	* sed/compile.c(mark_subst_opts,read_label,compile_program):
+	wherever we accept a ; as a command terminator, also allow a } or
+	a # to appear.  (This allows for less cluttered-looking scripts,
+	such as: sed '/foo/{x;G}' (instead of: sed '/foo/{x;G;}').)
+
+Wed Sep  9 18:17:07 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	* sed/compile.c(compile_regex): use regncomp() instead
+	of regcomp(), so that a script with NULs in its REs
+	will work in the expected manner.
+
+	* sed/compile.c(ADDNUL,REGNCOMP): added support macros
+	for above.
+
+	* lib/regex.c(regncomp,regcomp): added regncomp() and
+	made regcomp() a simple wrapper function.
+
+Mon Aug 31 21:48:30 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	* sed/sed.c(compile_program): if the first address of
+	a range is the number 0 (or a 0~N sequence), start
+	out in the "a1_matched" state.  This allows one
+	to match an initial chunk of a file without undue
+	convolutions for handling the case where the match
+	for the end of the sequence happens to be the first
+	line.
+
+Sun Aug 16 03:34:25 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	* sed/compile.c(snarf_char_class,match_slash): simplify
+	handling of "premature newline" error. Also, get the
+	line number right in the error message if we encounter
+	a "premature newline" during char-class snarfing.
+
+Sun Aug 16 02:59:20 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	* sed/compile.c: added N_() markers and corresponding gettext()
+	(er, _()) calls.
+
+	* Merged in i18n contribution from Erick Branderhorst
+	<Erick.Branderhorst@asml.nl>.  His ChangeLog entry
+	for the changes I've incorporated so far:
+
+1998-07-24  Erick Branderhorst  <Erick.Branderhorst@asml.nl>
+	* configure.in (ALL_LINGUAS, AM_GNU_GETTEXT): nl
+	* sed/{sed.h,utils.c}: #include <libintl.h> #define _(String)
+	gettext (String)
+	* sed/sed.c: #include <locale.h>
+	* po/POTFILES.in: sed/{compile,execute,sed,utils}.c
+	* run gettextize -f
+	* acconfig.h: #undef LOCALEDIR ENABLE_NLS HAVE_CATGETS
+	HAVE_GETTEXT HAVE_LC_MESSAGES HAVE_STPCPY
+
+Fri Aug 14 13:52:57 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	* Merged code from 3.02 with a branched development
+	tree from late May; the following (out-of-order)
+	changelog entry is from the branched tree.
+
+Sat May 30 12:23:16 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	* sed/compile.c, sed/execute.c: added (conditional on NOLEAKS macro)
+	code to free all dynamically allocated memory.
+
+	* sed/sed.c, sed/compile.c, sed/execute.c: much shuffling
+	of code --- ordered functions such that no forward
+	declarations are necessary, and placed all static prototypes
+	immediately before the actual function definition.
+	This accomplished two things: first, I find the new ordering
+	a more natural way to read the code than the previous
+	ordering, and second, the new ordering give the compiler
+	a better opportunity to discover inlining possibilities.
+	(The odd "prototype declaration+old-style definition"
+	style is used because I feel it is the least ugly way
+	of supporting K&R1 C while still getting the benefit of
+	prototypes when they are available.)
+
+	* sed/basicdefs.h: added MEMCPY() macro to hide the VCAST()s
+	that ought to be used with memcpy().
+
+	* sed/execute.c: Change calls to memcpy() to go through the
+	new MEMCPY() macro.  Various prototypes: elide variable name
+	if it does not add any human-useful documentary information
+	to the bare type.
+
+	* sed/sed.c(main): Updated calls to compile_string() to add third
+	(length) argument.  Changed call to obsolete close_all_files()
+	to a call to the new finish_program().
+
+	* sed/sed.c(map_file): Attempt to clean-up how "size" gets
+	cast and tested; remove spurious S_ISREG test (just let
+	mmap() fail if it doesn't support the underlying file type).
+
+	* sed/sed.c: Deleted old RX library stub declarations.
+
+	* sed/sed.c(map_file,unmap_file): added VCAST()s to the
+	mmap()/munmap() calls.
+
+	* sed/utils.c(ck_fclose): added support for ANSI C
+	functionality where passing a NULL argument means
+	to fclose() _all_ open streams.  (Well, almost.
+	Only closes streams which were previously ck_fopen()ed,
+	as I don't care to figure out how to autoconf-detect
+	whether fclose(NULL) is properly supported on a given
+	platform.)
+
+	* sed/sed.h: Renamed `struct text_buf' member `text_len'
+	to `text_length'.  Abstracted out `enum addr_types'
+	from `struct addr'; added new enum types num2,step,step_mod;
+	renamed mod to num_mod.  De-unionized the regex,number,
+	{modulo-offset/step} components of `struct addr', in
+	anticipation of new features.  Changed type of `a2' member
+	of `struct sed_cmd': now a pointer to save space.
+	Abstracted out `struct replacement' from `struct subst'.
+	Cleaned up declaration of `x' union of `struct addr'.
+	Fixed prototype for compile_string().  Replaced prototype
+	for old close_all_files() with one for new finish_program().
+
+	* sed/sed.h, sed/compile.c, sed/execute.c: changed to
+	simplify the data structures used for branches and
+	command blocks: simplified `struct vector'; made
+	`struct label' local to compile.c; `struct sed_cmd'
+	was modified to support a simpler design for branches
+	and blocks.
+
+	* sed/execute.c: Conditionally added ADDNUL() macro so that
+	the function call overhead is only incurred if nul_append()
+	_must_ be called.  Made some commentary edits, including
+	typo fixes.
+	* sed/execute.c(resize_line): changed semantics of "len" argument
+	from "additional length" to "target length"; made
+	INITIAL_BUFFER_SIZE a minimum allocation length.
+	* sed/execute.c(str_append): adjusted to new resize_line()
+	semantics.
+	* sed/execute.c(line_copy): use FREE()+MALLOC() instead of
+	REALLOC() to avoid unnecessary copying of old text; add the
+	"try doubling first" allocation heuristic (just like
+	resize_line() does).
+	* sed/execute.c(line_exchange): new function.
+	* sed/execute.c(nul_append): make whole function (not just its
+	body) conditional on HAVE_REGNEXEC macro; adjust to new
+	resize_line() semantics.
+	* sed/execute.c(read_mem_line): use str_append() instead if
+	custom in-line code; compensate for new default of
+	"line.chomped = 0" in read_pattern_space() by setting
+	"line.chomped = 1" where appropriate.
+	* sed/execute.c(read_file_line): use different trigger to
+	determine that "buffer" is uninitialized, and do a full
+	initialization if required; use str_append() instead of custom
+	in-line code in two places; compensate for new default of
+	"line.chomped = 0" in read_pattern_space() by setting
+	"line.chomped = 1" where appropriate.
+	* sed/execute.c(output_line): don't bother calling ck_fwrite()
+	if length==0.
+	* sed/execute.c(release_append_queue): new function.
+	* sed/execute.c(dump_append_queue): use release_append_queue()
+	instead of in-line equivalent.
+	* sed/execute.c(read_pattern_space): conditionalize call to
+	dump_append_queue() for alleged performance reasons; changed
+	default "line.chomped" value to more common "1", and added an
+	assignment of "0" where this made a difference.
+	* sed/execute.c(match_an_address_p): deleted "is_addr2_p"
+	argument; reorder cases to match order in enum declaration; add
+	cases for new "addr_is_num2", "addr_is_step", and
+	"addr_is_step_mod" address types; alter nul_append() call to be
+	through ADDNUL() macro; fix to new struct member and enum
+	spellings in (formerly addr_is_mod); addr_is_num_mod case.
+	* sed/execute.c(match_address_p): remove oblsolete third argument
+	to calls to match_address_p(); alter references to sed_cmd
+	member a2 to reflect new pointer status; add new support for
+	a2->addr_type addr_is_step and addr_is_step_mod cases.
+	* sed/execute.c(do_subst): add NOLEAKS support logic; use
+	ADDNUL() wrapper to nul_append(); simplify replacement
+	expansion by using the new "struct replacement" data structure;
+	use line_exchange() function instead of custom in-line code.
+	* sed/execute.c(process_files): added NOLEAKS code.
+	* sed/execute.c(execute_program): updated implementations
+	of the `{', `}', `:', `b', and `t' commands; modified
+	`c' command gratuituosly; fixed potential memory
+	overrun in `D' command.  Simplified how nonstandard
+	`loop increments' work.  Use line_exchange() instead of
+	custom in-line code in 'x' case.
+	* sed/execute.c[EXPERIMENTAL_DASH_N_OPTIMIZATION conditional
+	code]: various modifications intended to keep this
+	code in sync with the new changes, but the code still
+	retains its previous bugs.
+
+	* sed/compile.c: use "exit(EXIT_FAILURE) instead of "exit(1)",
+	just in case we get compiled under VMS.
+	* sed/compile.c: Change type of prog_info.base to decrease needs
+	for casting; then elimiated the casts in question ;-).
+	* sed/compile.c: Added struct sed_label (moved from sed.h, then
+	modified).
+	* sed/compile.c: Removed "readit_p" flag from struct fp_list.
+	* sed/compile.c: Added module-global "blocks" variable.
+	* sed/compile.c: Extracted more error-message constant strings
+	to named variables.
+	* sed/compile.c(check_final_program): updated to
+	reflect new data structures and use new fucntions.
+	Added call to compile_regex() to release unneeded
+	memory.
+	* sed/compile.c: deleted obsolete new_vector() function;
+	abstracted new read_label() function; abstracted new
+	release_label() function; added new `blocks' module-static
+	variable.
+	* sed/compile.c(compile_program): updated implementations
+	of the `{', `}', `:', `b', and `t' commands; modified
+	initialization from NULL vector.
+	* sed/compile.c(compile_regex): added mechanism to
+	release memory consumed by the cached `last' RE.
+	* sed/compile.c(setup_jump,setup_label): updated
+	name (from setup_jump to setup_label) and prototype;
+	changed body to reflect data structure changes.
+	* sed/compile.c: Add OPEN_BRACE and CLOSE_BRACE macros for better
+	"vi" editing behavior.
+	* sed/compile.c(compile_filename,read_filename,get_writefile):
+	Replaced function compile_filename() with more orthogonal functions
+	read_filename(), get_writefile().
+	* sed/compile.c(compile_regex): Added ability to free the remembered
+	"last RE" in compile_regex (for benifit of "NOLEAKS" code).
+	* Made adjustments dictated by the change to struct sed_cmd which made
+	the a2 member a pointer-to-addr instead of an addr.
+	* sed/compile.c(setup_jump,read_label,setup_label,release_label):
+	Added functions read_label(), setup_label(), release_label(); deleted
+	function setup_jump().
+	* sed/compile.c(new_replacement,setup_replacement,release_replacement):
+	new functions.
+	* sed/compile.c: Adjusted to new spelling of text_buf member
+	("text_length" instead of "text_len").
+	* sed/compile.c(new_vector): deleted function.  (Due to new handling
+	of blocks, only one instance remained, and that one was just as
+	clear in-lined.)
+	* sed/compile.c(compile_string): Added third argument; it now
+	takes a counted string instead of a NUL-terminated string.
+	* sed/compile.c(compile_file): added variable "map_base" to
+	compensate for new type of prog_info.base.
+	* sed/compile.c(check_final_program): reflect new style of
+	handling blocks and struct sed_label.
+	* sed/compile.c(close_all_files,finish_program): replaced function
+	close_all_files() with more generic finish_program().
+	* sed/compile.c(read_text): added new feature: if first non-blank
+	character after the {a,i,c} command character is not "\", then
+	use the trailing text on that line as the (first) line of text.
+	Also added code conditional on NO_INPUT_INDENT to support the
+	"feature" of stripping leading blanks from each input line; I
+	do not read POSIX as permitting this behavior, nor do I think
+	it is a good idea, so it is disabled by default, but some have
+	argued that this blank-stripping is the "correct" behavior, so
+	I offer them the option of building their sed that way.
+	* sed/compile.c(compile_address): added xxx,+n and xxx,~n addressing;
+	simplified code.
+	* sed/compile.c(compile_program): added BAD_PLUS error detection;
+	adjusted to new cur_cmd->a2 pointer status; added addr_is_num2
+	detection; deleted pointless "a2->addr_number < a1.addr_number"
+	check (addr_is_num2 semantics handle this just fine); updated
+	code for '{', '}', ':', 'b', and 't' to reflect new design
+	of branch handling, including making use of new functions
+	related to the new design); added support for feature already
+	mentioned in read_text() where {a,i,c} commands are able to have
+	their text start on the same line as the command; changed some
+	error messages (hopefully for the better); localized variables
+	specific to individual commands (particularly 's' and 'y');
+	made use of new setup_replacement() function in 's' command.
+
+Mon Aug 10 19:58:49 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	* doc/sed.texi, doc/sed.1: sedtut10.txt is apparently dead.
+	Deleted references to it and added a pointer to
+	http://seders.icheme.org/tutorials/.  (Pointed out by
+	Joerg Heitkoetter <joerg@de.uu.net>.)
+
+Sat Aug  8 18:11:57 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	* djgpp/config.btm: per request by Michel de Ruiter
+	 <mdruiter@cs.vu.nl>, added "%1" to "%9" parameters.
+
+Mon Aug  3 11:44:55 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	* doc/sed.texi: fix a couple of typos.  (Submitted by
+	Alan Modra <alan@spri.levels.unisa.edu.au>.)
+
+Sat Aug 01 17:49:06 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	*** Version 3.02 released
+	
+	* configure.in: Because of code change in 3.01a, bump the
+	minor revision number for the release (now 3.02).
+
+Sun Jul 26 16:07:55 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	*** Version 3.01a released
+	
+	* sed/compile.c(snarf_char_class):  the POSIX char-class
+	recognition loop forgot to update its concept of "prev"
+	as the loop progressed.
+
+	* testsuite/Makefile.am: The dependency of version.good
+	on [testsuite/]Makefile introduced in the previous
+	release was botched -- it referred to "Makefile"
+	as "$(srcdir)/Makefile, which of course doesn't work
+	if you aren't building in the source tree.
+
+	* djgpp/Makefile.am: add forgotten "config.btm" EXTRA_DIST
+	member.
+
+	* configure.in: update version.
+
+Tue Jul 21 06:04:42 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	*** Version 3.01 released
+	
+	* configure.in: mark as release version!
+
+	* Makefile.am: add BUGS and THANKS to the EXTRA_DIST target.
+
+	* testsuite/Makefile.am: add dependency of version.good
+	on [testsuite/]Makefile.
+
+Mon Jul 20 12:38:10 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	* djgpp/config.btm: New file to support the 4DOS alternative
+	to command.com.  (Sumitted by Eli Zaretskii on behalf of
+	an anonymous 4DOS user.)
+
+Fri Jul 17 00:36:34 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	*** Version 3.01-beta18 released
+	
+	* djgpp/config.sed: my "tweak" in beta17 was too
+	hastily considered.  Back it out.
+
+	* configure.in: update to beta18.
+
+Wed Jul 15 01:02:15 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	*** Version 3.01-beta17 released
+	
+        * djgpp/config.sed: tweak/simplify s,,, commands at end.
+
+	* configure.in: update to beta17.
+
+1998-07-14  Eli Zaretskii  <eliz@is.elta.co.il>
+
+	* djgpp/config.sed: Edit all the occurences of = in the context of
+	--option=value, including in the help messages, into
+	--option:value, but leave DOS-style d:/foo/bar file names intact.
+
+	* djgpp/config.bat: Use --srcdir:foo instead of --srcdir=foo.
+
+	* testsuite/Makefile.am (help, version): Remove temporary files
+	explicitly, don't use shell wildcards, so it works under DOS 8+3
+	limits.
+
+Thu Jul  9 13:06:00 PDT 1998 16:51:43 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	*** Version 3.01-beta16 released
+	
+	* djgpp/config.sed: tweak the configure script to use :
+	instead of = for --with-foo=bar option parsing, to
+	work around problems with how command.com handles =s.
+
+Wed Jul  8 16:51:43 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	* djgpp/config.bat: correct inappropriate behavior that I
+	introduced in the beta13 changes (if first argument is
+	a directory, it needs to be handled as the --srcdir).
+
+	* testsuite/version.gin, testsuite/version.good, testsuite/Makefile.am:
+	Add target to automake to automatically update version.good
+	from (new file) version.gin, instead of hand-editing the version
+	number each release.
+
+	* testsuite/Makefile.am: miscellaneous gratuitious tweakage --
+	mainly adding $(RM) commands just because I didn't like
+	leaving the tmp* files from successful runs laying about.
+	Also some editorial comments.
+
+	* configure.in: update to beta16.  Added and commented out
+	experiment with AC_OUTPUT() for testsuite/version.good.
+	Added code to properly handle bare (without =xxx)
+	"--with-regex" option.
+
+Sun Jul  5 21:02:16 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	*** Version 3.01-beta15 released
+	
+	* sed/utils.c(ck_fflush), sed/utils.h, sed/execute.c(output_line):
+	add and use new ck_fflush() function.
+
+Sun Jul  5 15:23:47 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	* sed/compile.c(bad_prog): add more detail to error
+	messages about -e strings.
+
+Sun Jul  5 14:29:45 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	* sed/compile.c(mark_subst_opts), sed/execute.c(do_subst):
+	Define better semantics for interaction of the `g' flag
+	with a numeric flag to the s/// command.  It used to
+	be that the `g' command siezed control; now the first
+	(number-1) matches are skipped and then `g' gets control
+	after that.  (It is not clear whether this is a feature
+	sneaking in during late beta, or a bug fix; the changes
+	involved were trivial, so I decided to treat it as a bug
+	fix.)
+
+	* configure.in, testsuite/version.good: update to beta15.
+
+Sat Jul  4 09:54:45 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	*** Version 3.01-beta14 released
+	
+	* sed/basicdefs.h, sed/compile.c, sed/execute.c:
+	per report by "Kaveh R. Ghazi" <ghazi@caip.rutgers.edu>,
+	copied the ISXXX macros from lib/regex.c so that
+	silly machines which require isascii() to be true
+	before the other isXXX() macros are valid will
+	still work.
+
+	* configure.in, testsuite/version.good: update to beta14.
+
+Thu Jul  2 23:46:13 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	*** Version 3.01-beta13 released
+	
+	* configure.in, acconfig.h: set USE_REGEX_GNU_H symbol if we
+	are going to be using lib/regex.c.
+
+	* lib/Makefile.am, lib/regex.h, lib/regex-gnu.h, lib/regex.c:
+	rename lib/regex.h to lib/regex-gnu.h, so that those who
+	choose to use a different regex implementation will not
+	pick-up lib/regex.h when doing "#include <regex.h>".
+
+	* sed/regex-sed.h, sed/Makefile.am, sed/compile.c, sed/execute.c,
+	sed/sed.c: create sed/regex-sed.h which acts as a switch
+	to choose either lib/regex.h or the user-supplied <regex.h>,
+	depending on the value passed to configure's --with-regex=
+	option.
+
+Thu Jul  2 17:22:31 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	* configure.in: if an alternative --with-regex= is given,
+	do an AC_CHECK_FUNCS(regnexec regexec) to ensure that
+	at least one of these functions is available.  Also,
+	parallel changes for the default case.
+
+	* sed/execute.c, acconfig.h: retire use of the WITH_REGNEXEC
+	test macro in favor of HAVE_REGNEXEC test macro created
+	by above change.
+
+	* djgpp/config.bat: Play games to handle "install-sh",
+	DOS filename restrictions, GNU makefile default rules,
+	and getting a correct run of "configure" (contributed
+	by Eli Zaretskii <eliz@is.elta.co.il>).
+
+	* djgpp/Makefile.am, testsuite/Makefile.am, testsuite/Makefile.in,
+	Makefile.am, configure.in: Various automake targets
+	(such as distcheck) failed with old configuration.
+	The simplest solution was to just add these .am
+	files.  (The testsuite/Makefile.in was just renamed to
+	testsuite/Makefile.am, then various redundant defines and
+	targets were deleted.)  (Reported by Erick Branderhorst
+	<Erick.Branderhorst@asml.nl>.)
+
+	* testsuite/dc.good, testsuite/dc.inp: per suggestion from
+	Greg Ubben <gsu@romulus.ncsc.mil>, use base 16 output to
+	exercise even more of the dc.sed script.
+
+	* configure.in, testsuite/version.good: update to beta13.
+
+Sun Jun 28 16:21:02 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	*** Version 3.01-beta12 released
+	
+	* doc/sed.texi: Avoid mixing @code and @samp markups together:
+	they look ugly in Info.  Use @url and @email instead of @example.
+	Add indexes.  (Basis of changes contributed by Eli Zaretskii.)
+
+	* djgpp/*, Makefile.am: add support for the DJGPP compiler,
+	contributed by Eli Zaretskii <eliz@is.elta.co.il>.
+
+	* dc.sed, testsuite/Makefile.in, testsuite/dc.inp, testsuite/dc.good:
+	added this remarkable script, written and contributed
+	by Greg Ubben <gsu@romulus.ncsc.mil>, both as a work of
+	art for general admiration, and also for use in regression
+	testing.
+
+	* configure.in, lib/Makefile.am: add --with-regex=regexlib
+	option, which overrides the use of lib/regex.c.
+
+	* configure.in, testsuite/version.good: update to beta12.
+
+Fri Jun 12 16:41:48 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	*** Version 3.01-beta11 released
+	
+	* sed/compile.c: add module-static variables first_script
+	(for #n change below) and pending_text (for a/c/i change
+	below).
+
+	* sed/compile.c(compile_file), sed/compile.c(compile_program):
+	Instead of having #n trigger the -n option in *any file*,
+	have #n trigger the -n option only if they are the first
+	two bytes of the first script or script-file.
+
+	* sed/compile.c(compile_string), sed/compile.c(compile_file):
+	clear the first_script variable at end of these functions.
+
+	* sed/sed.h: tease out the struct text_buf declaration from
+	struct sed_cmd, so that a pointer to such can be passed
+	to new sed/compile.c(read_text) function.
+
+	* sed/compile.c(compile_program), sed/compile.c(read_text):
+	Tease out handling of text to a/c/i commands to new
+	read_text() function.  Handle (via aid of pending_text
+	variable) texts which span more than one script/script-file
+	option.  In particular, restore the ability to have this
+	work:  sed -e '1i\' -e 'foo'
+
+	* sed/compile.c(check_final_program): close off any dangling
+	pending_text allocation.
+
+Thu Jun 11 11:17:46 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	* sed/execute.c(do_subst): fixed two bugs: s/ */X/g was failing
+	to match the final empty string after the end of the pattern
+	space; and /^foo$/s/o/x/3p was printing, despite the failure
+	to do a substition.
+
+Fri Jun  5 04:40:24 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	* configure.in: change the AC_ARG_WITH(regnexec, ...)
+	to be the more appropriate AC_ARG_ENABLE(regnexec, ...).
+
+	* configure.in, testsuite/version.good: update to beta11.
+
+Fri Jun  5 00:54:25 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	*** Version 3.01-beta10 released
+	
+	* sed/execute.c: forgot to P_() the prototype and
+	old-style the declaration for bootstrap_memchr()!
+
+Thu Jun  4 18:42:30 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	* sed/compile.c(snarf_char_class): added code to
+	recognize \n or \<newline> sequence within a
+	char-class as the newline character.
+
+Tue Jun  2 11:56:02 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	* configure.in: added check for <sys/types.h> and
+	a AC_ARG_WITH(regnexec,...) check, to simplify use
+	of other regex libraries which have regexec() but
+	not regnexec(), with the corresponding loss of
+	functionality (regexps will not work right against
+	input lines which contain NULs).
+
+	* sed/execute.c: add nul_append() function, a #define
+	for a regnexec() -> regexec() macro (conditional on
+	the lack of the WITH_REGNEXEC symbol), and a couple
+	of calls to nul_append() (in match_an_address_p()
+	and do_subst()) to permit the use of the POSIX standard
+	regexec() function call instead of the suggested
+	regnexec() call.
+
+	* sed/compile.c, sed/execute.c, sed/sed.c: check for
+	<sys/types.h> and include it (before "regex.h") if
+	available.  This makes it simpler to use the system's
+	regex library instead of the one in lib/regex.c, should
+	that be desired.
+
+Tue Jun  2 08:41:05 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	* sed/basicdefs.h: define VCAST macros to allow sed to
+	compile on systems which predate the definition
+	of "void *", and yet still get feedback about
+	stupid programming errors from systems which *do*
+	know about "void *"s.  Also define MALLOC, REALLOC,
+	MEMDUP, and FREE macros to keep under control the
+	degree of code ugliness which would otherwise be
+	introduced in making use of the VCAST macro.
+
+	* sed/compile.c, sed/execute.c, sed/sed.c, sed/utils.c:
+	pervasively use the new VCAST, MALLOC, REALLOC, MEMDUP,
+	and FREE macros wherever appropriate.
+
+	* sed/utils.c, sed/utils.h: correct type of first arguments
+	to ck_fread() and ck_fwrite() to be [const] VOID *.
+
+	* sed/basicdefs.h, sed/execute.c: protect against
+	the rumored systems which stupidly #define __STDC__ 0.
+
+	* testsuite/help.good, testsuite/Makefile.in: make
+	the ``help'' test insensitive to the spelling of
+	the executable's name.  Also, enhanced `make clean'
+	target.
+
+	* doc/sed.texi, doc/sed.1: correct documentation of `q'
+	command; fix typos.
+
+	* configure, testsuite/version.good: update to beta10.
+
+Sat May 30 17:28:00 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	*** Version 3.01-beta9 released
+	
+	* Makefile.am: make testsuite a normal SUBDIR.
+
+	* configure.in: discontinue using AC_ISC_POSIX --
+	check for -lcposix library instead; added
+	testsuite/Makefile to AC_OUTPUT list.
+
+	* lib/memmove.c(memmove): fixed wrong sense used
+	for HAVE_BCOPY test.
+
+	* sed/execute.c: checked more specifically for a version
+	of gcc which supports __attribute__ (i.e., >= 2.7).
+
+	* testsuite/*: renamed files to fit 14 char limit.
+
+	* testsuite/Makefile, testsuite/Makefile.in: Makefile
+	renamed to Makefile.in and then modified so that
+	"make -j check" from top directory will work.
+
+	* testsuite/subwrite.sed, testsuite/writeout.sed: changed
+	file name of the "w" command to be consistent with the
+	new naming used in testsuite/Makefile.in.
+
+	* doc/sed.1, doc/sed.texi: fixed some typos, formatting
+	glitches, and poor wordings.
+
+Sat May 30 04:02:29 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	* configure.in: specify that config.h is to be derived
+	from config_h.in in order to avoid the braindead
+	DOS filesystem limitations.
+
+Fri May 29 21:56:30 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	* sed/compile.c(compile_address), doc/sed.texi: gave
+	a better definition to the meaning of N~0 address
+	forms -- N~M addresses now mean that lines match
+	when there exists a non-negative x such that
+	lineno == N+x*M.
+
+Fri May 29 12:07:38 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	* sed/compile.c(compile_address),
+	sed/execute.c(match_an_address_p): update semantics of
+	N~M address form: now N is the first line which will
+	match and M is the step between succeeding matches.
+	If N<M this works out to the same as before, but the
+	new behavior for N>=M seems more useful.
+
+	* doc/sed.1, doc/sed.texi: update documentation of N~M
+	address form; added "Other Resources" node to sed.texi;
+	minor formatting changes to some items in sed.1 with
+	an eye to improving clarity.
+
+	* configure.in, testsuite/version.good: update to beta9.
+
+Sat May 23 20:04:31 HST 1998  Ken Pizzini <ken@gnu.org>
+
+	*** Version 3.01-beta8 released
+	
+	* sed/compile.c(compile_regex): forgot to make last_re be
+	a *copy* of the buffered text in today's earlier fix.
+
+	* sed/execute.c(read_file_line): EOF check was wrong --
+	it forgot to allow for the possibility that we were
+	appending to the end of the ``line'' (instead of merely
+	reading a fresh line).
+
+Sat May 23 18:07:18 HST 1998  Ken Pizzini <ken@gnu.org>
+
+	* sed/compile.c(compile_regex): don't track compiled version
+	of regex -- the modifiers may change.  Track the regex
+	source instead.  (For "last regex" (aka //) notation.)
+
+	* configure.in, testsuite/version.good: update to beta8.
+
+Sat May 23 16:07:09 HST 1998  Ken Pizzini <ken@gnu.org>
+
+	*** Version 3.01-beta7 released
+	
+	* sed/execute.c: #undef'd EXPERIMENTAL_DASH_N_OPTIMIZATION
+	because its code is buggy.
+
+Tue May 19 17:03:52 HST 1998  Ken Pizzini <ken@gnu.org>
+
+	* sed/sed.c: label rx library code as such with #ifdefs
+	(instead of just #if 0).
+
+	* sed/compile.c(compile_program): make incremental
+	improvement to the "Unknown command" error message.
+
+Sat May 16 23:16:26 HST 1998  Ken Pizzini <ken@gnu.org>
+
+	* testsuite/Makefile: simplify: get rid of automatic run
+	against system's sed; don't time by default; allow for
+	alternative comparison command.
+
+	* configure.in, testsuite/version.good: update to beta7.
+
+Wed May 13 21:44:28 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	*** Version 3.01-beta6 released
+	
+	* lib/Makefile.am: fix spelling of libsed_a_LIBADD in
+	libsed_a_DEPENDENCIES.
+
+	* configure.in, testsuite/version.good: update to beta6.
+
+Wed May 13 14:38:08 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	*** Version 3.01-beta5 released
+	
+	* sed/execute.c(do_subst): added not_bol_p variable to track when
+	we have iterated past the beginning of the pattern.
+	[Thanks to Jim Meyering <meyering@ascend.com> for the bug report.]
+
+Wed May 13 13:54:04 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	* sed/execute.c(bootstrap_memchr): new function.  When
+	bootstrapping we don't know if we are on a 64-bit machine,
+	so lib/memchr.c breaks.  Supply this (slow) implementation
+	just to get us bootstrapped.
+
+	* bootstrap.sh: add a #define BOOTSTRAP symbol; add -I.
+	for emphasis for the compiles in sed/; be explicit
+	about what files we're bothering to compile.
+
+	* configure.in, testsuite/version.good: update version
+	to beta5.
+
+Wed May 13 06:39:06 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	*** Version 3.01-beta4 released
+	
+	* rename writeout.good? to wrtout?.good and subwrite.good? to
+	subwrt?.good to comply with DOS 8+3 file name restrictions.
+	[Eli Zaretskii <eliz@is.elta.co.il> suggested this to
+	simplify DJGPP ports, and it was easy.]
+
+	* testsuite/Makefile: reflect above name changes.
+
+Wed May 12 21:09:32 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	* sed/sed.c(usage): fix non-portable omission of \n\ at end of
+	lines within long string.
+
+	* sed/sed.c(main): remove spurious argument to fprintf() in the
+	'V'ersion output.
+
+	* sed/execute.c(line_append): embed newline between the two
+	text fragments unconditionally.
+
+	* sed/execute.c(do_subst): change structure assignment to memcpy()
+	(for portability reasons).
+
+	* README.bootstrap: suggest using -w option.
+
+Tue May 12 10:02:37 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	* configure.in: use AC_REPLACE_FUNCS where appropriate.
+
+	* lib/Makefile.am: updated to reflect AC_REPLACE_FUNCS change in
+	configure.in.
+
+	* lib/memchr.c lib/memcmp.c: revert to standard GNU versions.
+
+	* lib/alloca.c: added this missing file.
+
+	* testsuite/version.good: updated for new version identifier.
+
+Mon May 11 18:50:56 PDT 1998  Ken Pizzini <ken@gnu.org>
+	
+	*** Version 3.01-beta3 released
+	
+	* sed/Makefile.am: fix INCLUDES to work right with VPATH.
+	[Thanks to Jim Meyering <meyering@ascend.com> for the bug report.]
+
+	* sed/sed.c(usage): make --help output more user-friendly?
+
+	* sed/execute.c(execute_program): fix bug in 'x' command introduced
+	in the alleged portability fix of May 9.
+
+	* configure.in: update version to 3.01-beta3.
+
+	* testsuite/version.good, testsuite/help.good: freshen with
+	latest output.
+
+Sat May  9 22:35:45 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	*** Version 3.01-beta2 released
+	
+	* sed/sed.c: add #include <sys/types.h> in HAVE_MMAP
+	block (needed on some machines).
+
+	* lib/memmove.c: #include <memory.h>, if HAVE_MEMORY_H.
+
+Sat May  9 21:29:00 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	* configure.in: remove dangling references to rx library;
+	added HEADER and FUNC checks for items used by source in
+	lib/.
+
+	* lib/ansidecl.h, lib/memcopy.h, lib/pagecopy.h, lib/string.h
+	lib/memcpy.c, lib/memmove.c: deletes these files.  There
+	are still pieces of glibc missing to support these, and
+	it isn't worth the headache right now.
+
+	* lib/memmove.c: de novo, simpler version.  Uses bcopy()
+	if available, and slow-but-simple code if not.
+
+	* lib/Makefile.am: remove references to deleted files.
+	Added forgotten reference to memcpy.c.  Re-ordered
+	SOURCE entries to reflect dependencies for systems
+	which lack ranlib.
+
+	* sed/basicdefs.h: updated to reflect above changes to lib/,
+	and experience with non-STDC compilers.
+
+	* lib/regex.c: made regerror() function publicly visible.
+
+	* lib/strerror.c: use old-style function declaration.
+
+	* sed/compile.c, sed/execute.c, sed/sed.c, sed/utils.c,
+	sed/sed.h, sed/utils.h: ensure that private definitions of
+	some symbols do not cause problems when #include'ing system
+	headers (mainly by re-ordering the #include directives).
+	(This is particularly an issue for bootstrap.sh runs.)
+
+	* sed/execute.c (execute_program): use memcpy() instead of
+	structure assingment ('x' command), for portablility to
+	old compilers.
+
+	* sed/execute.c (slow_getline): use old-style function
+	declaration, with a P_ prototype.
+
+	* sed/sed.c: change the type of the fallback MAP_FAILED
+	definition to work on archaic systems.  (Modern systems
+	should be defining it themselves, so the change from
+	void * shouldn't be a problem.)
+
+	* bootstrap.sh, README.bootstrap: actual testing of bootstrap
+	code revealed that I was too optimistic.  Redesigned and
+	replaced implementation.
+
+	* testsuite/Makefile: ignore errors from reference-implementation
+	seds that aren't up to snuff.
+
+	* testsuite/help.good, testsuite/version.good: update to
+	current version's output.
+
+Fri May  8 15:08:28 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	*** Version 3.01-beta1 released
+	
+	* sed/sed.c (main, usage): once again tweak the --help and
+	--version output to bettery comply with GNU coding standards.
+
+	* testsuite/help.good, testsuite/version.good: update to
+	reflect above change.
+
+	* doc/sed.texi: fix "Invoking" node's spelling to comply
+	with GNU standards.
+
+Fri May  8 11:43:10 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	* doc/sed.1, doc/Makefile.am: wrote (very basic) man page.
+
+Thu May  7 20:40:21 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	* lib/Makefile.am, lib/memmove.c, lib/memchr.c, lib/regex.c,
+	lib/memcpy.c, lib/regex.h, lib/memcopy.h, lib/string.h,
+	lib/pagecopy.h, lib/ansidecl.h: grab yet-another-version
+	from gnu.org for baseline and/or edit copyright boilerplate
+	using official lgpl2gpl.sed script.  Take care not to
+	loose regnexec() interface or special conditional-compilation
+	code.
+
+Wed May  6 23:35:12 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	* lib/regex.c, lib/regex.h: take from grep-2.1 distribution,
+	then trivially added the regnexec() interface.
+
+	* sed/sed.c, sed/compile.c, sed/execute.c: made modifications
+	to work with regex instead of rx.
+
+	* rx/*: deleted directory; the code is just too slow.
+	I think it will be easier to extend regex to fully
+	support POSIX.2 than to tune rx to be reasonable.
+	Even if this supposition is wrong, I'd rather make
+	the 3.01 release with the slightly deficient regex.
+
+	* Makefile.am lib/Makefile.am, sed/Makefile.am: made changes
+	related to the substitution of regex for rx.
+
+	* lib/Makefile.am, sed/Makefile.am: since regex is not a
+	``compatability'' module, changed name of library to
+	``libsed.a''.
+
+	* lib/memchr.c, lib/memcpy.c, lib/memmove.c: add conditional
+	compilation code to leave zero-sized .o file if system
+	already supports the implemented function.
+
+	* testsuite/help.good, testsuite/version.good: brought
+	up-to-date (once again).
+
+	* NEWS, ANNOUNCE: changes to reflect this batch of changes.
+
+Wed May  6 18:40:47 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	* sed/execute.c: discovered awful bug in '}' handling:
+	it could read past the end of vec (because `n' was
+	being decremented below zero)!  Needed to "continue"
+	instead of "break".
+
+Tue May  5 14:34:38 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	* doc/sed.texi, doc/version.texi: wrote some rudimentary
+	texinfo documentation.
+
+	* ANNOUNCE, NEWS, README, README.rx, Makefile.am:
+	more updates for the upcoming beta-release.
+
+	* sed/compile.c, sed/execute.c, sed/sed.c, sed/utils.c,
+	sed/sed.h, lib/strerror.c: update copyright notice text.
+
+Fri May  1 15:41:37 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	* sed/execute.c (match_an_address_p, match_address_p): if
+	the second element of an address range is a line number,
+	and that line number is *less than* (or equal to) the
+	current line number, we only match the one line (per
+	POSIX.2, section 4.55.7.1).  [Bug discovered as reported
+	in the seders mailing list FAQ.]
+
+	* AUTHORS, NEWS, acconfig.h, configure.in, doc/Makefile.am,
+	lib/Makefile.am, sed/Makefile.am, lib/README,
+	testsuite/help.good, testsuite/version.good:
+	Updated in anticipation of the 3.01-beta1 release.
+	Reorganized development source tree to make creation
+	of a distribution simpler.  Most notable changes were
+	to the various Makefile.am files and configure.in, but
+	some minor edits (such as deleting or changing #include
+	directives) have been made in many other source files.
+
+	* bootstrap.sh, README.bootstrap: created a mechanism for
+	creating sed on a system which lacks a working sed.
+
+Thu Apr 16 23:52:11 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	* sed.h, sed.c, execute.c, compile.c: did a spell-check on
+	the comments; fixed several typos.
+
+Thu Apr 16 13:43:01 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	* execute.c (do_subst): fixed bug where the "replaced" flag
+	was being set to one inappropriately when at least one
+	but fewer than sub->numb matches of the regexp were found.
+	(Thanks to Simon Taylor <staylor@hermes.iaccess.com.au>
+	for the bug report.)
+
+Wed Apr 15 11:35:31 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	* sed.h, sed.c, compile.c, execute.c: having a concern that
+	a cast was being done inappropriately, and realizing that
+	there is no quick way to locate all casts in a program, I
+	went through and marked all casts with a simple macro.
+	Now it is a simple matter to locate the casts, and it is
+	also a simple matter to turn of casts for a lint session
+	(if it should be desired).
+
+Wed Apr 15 10:29:21 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	* compile.c, sed.c: redo compile phase so that brace
+	expressions can be spread across multiple files.
+	For example:
+	  printf '{' >a; printf 'l;d' >b; printf '}' >c
+	  sed -f a -f b -f c foo
+	will now compile (and work), instead of complaining
+	about an unmatched '{'.  The mess created in compile.c
+	allowed a little simplification to the command-line
+	processing of "-e" options in sed.c.
+
+	sed.h: added (opaque) err_info member to struct vector;
+	added comments to the members of struct vector.
+
+Wed Apr 14 23:50:50 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	* sed.h, sed.c, compile.c, execute.c: added types countT and
+	flagT in order to clarify what various "int"s were doing.
+	Also makes it easy to change the type used for counts
+	(for example, to "unsigned long long") if desired, although
+	there are still some gotchas (such as the printf() format
+	for the '=' command).
+
+Tue Apr 14 17:34:54 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	* execute.c (execute_program, process_files, count_branches,
+	shrink_program): Added a first attempt at program optimization.
+	We now can quit early if we are running with the "-n"
+	and all of the commands are known to be valid only for
+	lines less than the current line.  Thus the "sed" in
+	"foo | sed -n 1,2p" will print read three lines, printint
+	the first two, and then quit, regardless of how much longer
+	"foo" might run or output.  This optimization does not buy
+	much in most cases (it sometimes even costs a little),
+	but when it does help it can help big.  The code is
+	all conditionally compiled based on the
+	EXPERIMENTAL_DASH_N_OPTIMIZATION symbol being #defined,
+	so it can be easily omitted if it causes problems.
+
+Tue Apr 14 12:25:06 PDT 1998  Ken Pizzini <ken@gnu.org>
+
+	* execute.c (test_dollar_EOF, last_file_with_data_p):
+	test_dollar_EOF() was incorrectly returning a false (0)
+	when there were unprocessed files, none of which had any
+	data (either unopenable or zero-length).  Created
+	last_file_with_data_p() to detect this situation, and
+	modified test_dollar_EOF() to make use of it.
+
+Thu Apr  2 23:02:18 PST 1998  Ken Pizzini <ken@gnu.org>
+
+	* compile.c (match_slash): match_slash() did not handle
+	[.coll.], [=equiv=], and [:class:] sequences within a
+	character class.  Added snarf_char_class() [which is a
+	remote derivative of parse_char_class() from GNU ed-0.2]
+	to deal with the details, and altered match_slash()
+	to make use of it.  Also created the trivial
+	add_then_next() to avoid clutter in snarf_char_class().
+
+Thu Apr  2 20:34:42 PST 1998  Ken Pizzini <ken@gnu.org>
+
+	* execute.c, sed.c, sed.h: There was a severe bug in
+	how the code handled "sed 5n a b" when "a" consists
+	of exactly five lines -- it behaved like "sed 5q a b"!
+
+	Rearranged where files get opened -- large scale
+	changes primarily involving main(), process_files(),
+	and read_pattern_space(), but also touching on several
+	other parts of execute.c.  The read_pattern_space()
+	function became unwieldly and parts were split into
+	open_next_file(), closedown(), read_always_fail(),
+	read_mem_line(), and read_file_line().  The
+	at_end_of_file_p() function became obsolete and was
+	eliminated; test_dollar_EOF_p() was updated.  A few
+	global and module-static variables were elminated, and
+	"struct line" was extended; comments were added to the
+	"struct line" declartation to document some important
+	dependencies in it.
+
+	I undertook the reorganization with dread, but I
+	feel that the new organization is an improvement
+	well beyond just fixing the bug that inspired it.
+
+Thu Apr  2 01:16:25 PST 1998  Ken Pizzini <ken@gnu.org>
+
+	* execute.c (read_file_line, slow_getline): the fread()
+	buffering code gives insufficient feedback to a user
+	running sed with a tty input device, so I created
+	slow_getline() for reading from a tty device.
+	Additionally, EOF detection has been made a little more
+	sensitive to avoid requiring multiple EOFs to be entered
+	from a tty.
+
+	* configure.in: added isatty() check.
+
+Wed Apr  1 11:04:30 PST 1998  Ken Pizzini <ken@gnu.org>
+
+	* configure.in (CPPFLAGS, LDFLAGS, LIBS):
+	Set to appropriate values if large file support needs
+	explicit enabling.  Code fragment taken from a 1997-10-25
+	patch to gawk by Paul Eggert <eggert@twinsun.com>
+
+Thu Aug 14 17:43:27 PDT 1997  Ken Pizzini <ken@gnu.org>
+
+	* utils.c (ck_fclose): modified to ignore NULL parameter.
+
+Thu Aug 14 12:08:45 PDT 1997  Ken Pizzini <ken@gnu.org>
+
+	* execute.c: tweaked execute_program() to eliminate
+	gratuitous "goto" usage.
+
+Thu Aug 14 11:30:04 PDT 1997  Ken Pizzini <ken@gnu.org>
+
+	* compile.c: added case-insensitive modifier ('I') to
+	address and s/// regexps.  The s/// case also accepts
+	the more popular 'i' modifier.  (The address regexp
+	cannot use 'i' as a modifier, as that conflicts with
+	the use of the 'i'nsert command.)
+
+Thu Aug 14 09:29:06 PDT 1997  Ken Pizzini <ken@gnu.org>
+
+	* compile.c: abstracted out match_slash() from the s///, y///,
+	and address-regexp special-case codes.
+
+	* execute.c: made dump_append_queue() use ck_fread() instead
+	of hand-rolled error checking.
+
+Mon Jul 28 10:50:41 PDT 1997  Ken Pizzini <ken@gnu.org>
+
+	* sed.c, sed.h, execute.c: POSIX.2, section 4.55.7, says that
+	a newline must end *every* output line.  But I think that
+	it is useful (when seding a binary file) to omit a trailing
+	newline if the input lacks one.  Thus the addition of
+	POSIXLY_CORRECT behavior.
+
+	* execute.c: however, when seding multiple files my feeling
+	is that it makes sense to have each file but the last
+	behave as-if it ended in a newline.  Modified read_pattern_space()
+	accordingly.
+
+	* utils.c: realized that add1_buffer(), for performance reasons,
+	shouldn't be calling memcpy() (indirectly via add_buffer()),
+	so rewrote it.
+
+Sat Jul 26 23:08:28 PDT 1997  Ken Pizzini <ken@gnu.org>
+
+	* execute.c: attempted to make read_pattern_space more
+	efficient for the the non-mmap() case.
+
+	* utils.c, utils.h, execute.c: new function ck_fread()
+	created and used.
+
+Sat Jul 26 20:22:14 PDT 1997  Ken Pizzini <ken@gnu.org>
+
+	* execute.c, compile.c, sed.c: abstracted the mmap()
+	interface into map_file()/unmap_file() [sed.c], and
+	changed the ad-hoc code in compile_file() [compile.c]
+	and process_file() [execute.c] to make use of the new
+	interface.
+
+Sat Jul 26 19:45:46 PDT 1997  Ken Pizzini <ken@gnu.org>
+
+	* execute.c, compile.c, configure.in: Check to see if mmap()
+	is available; if so make use of it on regular files.
+
+	* compile.c: compile_file() now closes the input file
+	when it is through!
+
+Sun Jul 20 23:57:02 PDT 1997  Ken Pizzini <ken@gnu.org>
+
+	* compile.c: modified parsing to permit whitespace in more
+	places where it makes sense;
+	added backslash escaping to the y/// command, per POSIX.
+
+	* execute.c: Merged append_pattern_space() into read_pattern_space();
+	moved body of 's' command to new function do_subst();
+	moved body of 'l' command to new function do_list();
+	changed output of 'l' command to conform to POSIX.2;
+	made line handling conform to POSIX; added output_line() function;
+	redesigned append-space algorithm; added append_queue structure and
+	the next_append_slot() and dump_append_queue() functions.
+
+	* sed.h: moved the definition of what is now struct subst
+	outside of the definition of struct sed_cmd.
+
+Sat Jul 19 16:29:09 PDT 1997  Ken Pizzini <ken@gnu.org>
+
+	* sed.c, execute.c, sed.h, Makefile.am: Separated out the
+	pieces dealing with executing the program from the top-level
+	parameter parsing and control.
+
+Sat Jul 19 01:16:35 PDT 1997  Ken Pizzini <ken@gnu.org>
+
+	* sed.c, compile.c, sed.h, Makefile.am: separate out the
+	pieces dealing with compiling the program from the pieces
+	dealing with interpreting the result.
+
+	* compile.c: add functions in_nonblank() and in_integer(),
+	and change interface to compile_address() with an eye
+	to making code clearer.
+
+Fri Jul 18 13:35:50 PDT 1997  Ken Pizzini <ken@gnu.org>
+
+	* utils.c: attempt at a quasi-unification of the
+	STDC and traditional C approaches to panic().
+
+	* sed.c: eliminate some gratuitous bit twiddling.
+	(Using flag bits can be a useful technique, but
+	this code is cleaner without them.)
+
+	* sed.c: place mutually exclusive members of struct addr
+	within a union, mainly to document the exclusivity;
+	eliminate unused structure members from struct fp_list;
+	eliminate unnecessary module-global variables;
+	remove some #if 0 code that is too odd to keep;
+	allegedly simplified the 'l' case of execute_program();
+	allegedly simplified inchar();
+	localized some static variables;
+	renamed some variables to better document their purpose;
+	removed some goto-s rendered obsolete by other changes.
+
+Thu Jul 17 15:30:44 PDT 1997  Ken Pizzini <ken@gnu.org>
+
+	* utils.c, utils.h, sed.c: added and made use of
+	ck_free() function.
+
+	* utils.c, utils.h, sed.c: changed all the *_buffer()
+	functions to take/return an incomplete type
+	"struct buffer *" instead of using VOID *.
+
+	* utils.c, utils.h, sed.c: renamed "finish_buffer()"
+	to "free_buffer()", on the premise that the new
+	name better describes the function's purpose.
+
+Wed Jul 16 13:52:14 PDT 1997  Ken Pizzini <ken@gnu.org>
+
+	* utils.c, utils.h, sed.c: added and made use of
+	ck_memdup() function.
+
+	* sed.c: protected a call to add1_buffer() in
+	compile_program() which could have tried to
+	push an EOF if a a/i/c command ended with
+	a '\', EOF sequence.
+
+	* utils.c: added sanity check to add1_buffer() so that
+	EOF will not be added to the buffer.
+
+Wed Jul 16 03:56:26 PDT 1997  Ken Pizzini <ken@gnu.org>
+
+	* configure.in, compat.h, compat.c: added memchr.
+
+	* sed.c: got rid of arbitrary NUM_FPS limit;
+	made global functions and variables "static" where appropriate;
+	make various cosmetic changes, hopefully improving readability;
+	simplified some redundant predicates;
+	simplified some code, but nothing fundamental (yet?).
+
+Wed Jul 16 00:24:54 PDT 1997  Ken Pizzini <ken@gnu.org>
+
+	* alloca.c, getopt.c, getopt.h, getopt1.c: updated from
+	versions in textutils-1.22.
+
+	* Makefile.in, Makefile.am, configure.in: put in automake support.
+
+	* basicdefs.h, compat.h, compat.c [, sed.c, utils.c]: took out
+	some very ugly compatibility #ifdefs and packaged into one
+	place.
+
+	* sed.c, utils.c: some gratuitous formatting changes.
+
+	* utils.c: changed datatype of utils_id_s in order to
+	eliminate arbitrary array size.
+
+Sun Jul 13 17:00:26 PDT 1997  Ken Pizzini <ken@gnu.org>
+
+	* sed.c, utils.c, utils.h: de-linting oriented cleanup.
+
+Sun Jul 13 00:46:48 PDT 1997  Ken Pizzini <ken@gnu.org>
+
+	* sed.c: fixed bug which caused SEGV for files missing a
+	final newline.  Corrected calls to regnexec to pass the
+	proper parameters, in the proper order.
+
+Sat Dec 30 20:16:59 1995  Tom Lord  <lord@beehive>
+
+	*** Version 3.00 released

+	* sed.c: Use posix entry points to regexp functions.
+	Fix enough bugs to pass the test-suite.
+
+....... Jason Molenda  <crash@cygnus.com>
+
+	* testsuite/: trippy test suite.

+Wed May 11 07:46:24 1994  Chip Salzenberg  (chip@fin.uucp)
+
+	*** Version 2.05 released
+	
+	* sed.c (compile_address): Recognize numeric addresses.
+	Fixes typo made during installation of "~" feature.
+
+Sat Apr 30 17:17:38 1994  Tom Lord  (lord@x1.cygnus.com)
+
+	*** Version 2.04 released
+
+	* sed.c: applied a patch from
+	 From: kap1@tao.cpe.uchicago.edu (Dietrich Kappe)
+
+	 Dietrich writes:
+
+	 As my contribution to the creeping feature creature in sed,
+	 here is a new type of address. The address has form n~m,
+	 which means "the line number is equal to n modulo m." The
+	 modifications to sed are trivial, and the general
+	 usefulness of this address should be obvious. If m is 0 or
+	 missing, 1 is used in its place (could be a bug or a
+	 feature :-).
+
+Sat Apr 30 17:17:38 1994  Tom Lord  (lord@x1.cygnus.com)
+
+	* rx.c (solve_destination): protect `solution' more carefully.
+	This is a cleanup of a patch from Kevin Buettner
+	 (kev@cujo.geg.mot.com).
+
+Sat Apr 30 17:17:38 1994  Tom Lord  (lord@x1.cygnus.com)
+
+	* rx.c: make translation tables unsigned chars
+
+	* sed.c (main): Compile accumulated -e commands as
+	soon as a -f command comes along.  This ensures that
+	the commands are executed in the right order.
+
+Mon Oct 25 14:41:47 1993  Tom Lord  (lord@rtl.cygnus.com)
+
+	* sed.c (execute_program): 'w' flushes the buffer after it
+	writes -- diagnosed by doug@research.att.com.  'r' and 'w' to
+	the same file is now supported -- hopefully even in a way that
+	satisfies Posix (it now behaves differently from some
+	/bin/sed's and the spec is hard to read so i'm not sure).
+
+	Also, 'r' of a non-existent file is now permitted.
+
+Mon Oct 11 21:06:10 1993  Tom Lord  (lord@cygnus.com)
+
+	* sed.c (execute_program): remember that 'b' and 't' are more
+	like longjmp than goto.  Patch from tom@basil.icce.rug.nl (Tom
+	R.Hageman)
+
+	* rx.c: patch from From: fin!chip@rutgers.edu (Chip
+	Salzenberg) to get rid of compiler warnings.
+
+
+Sat Aug  7 01:04:59 1993  Tom Lord  (lord@unix7.andrew.cmu.edu)
+
+	*** Version 2.03 released

+
+
+Wed Jul 21 00:28:03 1993  Tom Lord  (lord@unix8.andrew.cmu.edu)
+
+	* alloca.c: upgraded to a more recent version
+
+	* rx.c (re_search_2): prefer matches with longer

+	to low numbered subexpressions.
+

+
+Fri Jul 16 01:12:08 1993  Tom Lord  (lord@unix8.andrew.cmu.edu)

+Thu May 27 11:13:03 1993  Tom Lord  (lord@unix3.andrew.cmu.edu)
+
+	* sed.c (execute_program, match_addr): caught more cases

+
+	* sed.c (execute_program): apply gaumondp's patch

+
+	* sed.c (execute_program):
+	If a second address is a regexp, never match it on the
+	same line as the first address.
+
+	* sed.c (compile_regexp):
+	Numeric ranges  x,y s.t. y < x are now treated as x,x.
+	There was a bug in that they were being handled like x,x+1.
+
+	* sed.c (execute_program, read_pattern_space,
+	append_pattern_space) don't add newlines to lines
+	that don't have them.
+
+Wed May 19 13:34:45 1993  Tom Lord  (lord@unix9.andrew.cmu.edu)
+

+
+	* alloca.c: new (standard) file
+
+	* configure.in: AC_CONSTified
+
+	* sed.c (compile_program): properly diagnose the error of
+	a missing command (e.g. sed /x/). (thanks gaumondp)
+
+	* sed.c (compile_regexp): handle character classes correctly.
+	Thanks gaumondp@ERE.UMontreal.CA
+	and  schwab@issan.informatik.uni-dortmund.de.
+
+Thu May  6 12:37:18 1993  Tom Lord  (lord@unix10.andrew.cmu.edu)
+
+	* sed.c (compile_filename, execute_program): don't use
+	`access' or `/dev/null'.
+
+	* sed.c (execute_program): 'N' at EOF should delete the pat buf.
+
+	* sed.c (compile_filename): truncate, don't append files
+	being openned for `w' or `s///w'
+
+	* sed.c (execute_program): -n switch shouldn't effect `i' or `c'.
+
+	* sed.c (compile_program): don't compile unescaped newlines
+	into the substitution string of an `s' command (they are an error).
+
+	* sed.c (compile_regex): correctly skip over character
+	sets that contain `]'.
+
+	* sed.c (execute_program): patch from gaumondp
+	Correctly handle empty-string matches in the case of an `s'
+	command with a repeat count.
+
+	* sed.c (compile_program): patch from gaumondp@ere.UMontreal.ca.
+	Don't consume characters after the label of a `b', `t' or `:' command.
+
+	* sed.c (compile_program): unmatched open braces are an error.
+
+	* sed.c (compile_file): when consuming an initial comment,
+	count lines correctly.
+
+Wed Nov 18 02:10:58 1992  Tom Lord  (lord@unix2.andrew.cmu.edu)
+
+	* sed.c (execute_program): Made s///p print even if -n was
+	specified.
+
+	* sed.c (compile_string): Changed the type of this function to
+	fix a compile warning.
+
+Wed Nov  4 17:15:34 1992  Tom Lord  (lord@unix7.andrew.cmu.edu)
+
+	* sed.c (main): Initialize the hold area to contain "\n"
+	instead of "".  In execute_program, all lines are expected
+	to be newline terminated.  Also, if H is the first command
+	in the script, the result is a pattern buffer that begins
+	with a blank line.  Thanks to pinard@iro.umontreal.ca
+	(Francois Pinard) for pointing out this and many other bugs.
+
+	* sed.c (execute_program): Fixed a case of `D' command.
+	Thanks Chris Weber <weber@bucknell.edu>
+
+	* sed.c: added new tests of no_default_output to make -n work.
+	Thanks Andrew Herbert <andrew@werple.apana.org.au>
+
+	* sed.c, configure.in,Makefile.in: autoconfed bcopy and const.
+	Thanks "J.T. Conklin" <jtc@gain.com>
+
+	* sed.c: made prog_cur, prog_start, and prog_end unsigned so
+	that users could write  `sed -e s/�/foo/g'.
+
+Tue Oct 13 00:04:05 1992  Tom Lord  (lord@unix3.andrew.cmu.edu)
+
+	* sed.c (execute_program): fixed the cycling behavior of 'D'
+
+	* sed.c: integrated patch that closes files
+
+	* sed.c: changed regexp syntax
+
+Fri May 22 15:11:12 1992  Tom Lord  (lord at moriarty.bh.andrew.cmu.edu)
+
+	* regex.c:  this is not my change, but a pointer to the fact
+	that karl@gnu fixed some regexp bugs that were plaguing sed.
+
+Thu Apr 30 13:02:21 1992  Tom Lord  (lord at unix3.andrew.cmu.edu)
+
+	* sed.c (compile_program, execute_program)
+	subprograms are now compiled with an explicit continuation ;)
+	return_v and return_i in struct vector.  execute_program
+	no longer recurses to execute subprograms (case '{') and now
+	understands a return instruction (case '{').
+
+Tue Apr 28 17:13:04 1992  Tom Lord  (lord at unix7.andrew.cmu.edu)
+
+	* sed.c (compile_address) added \?regexp? syntax for addresses.
+
+	* sed.c (main) added {} intervals to the obscure regexp
+	syntax.
+
+	* sed.c (compile_program)  after calling compile_address,
+	normalize numeric addresses (make a2.addr_number > a1.addr_number).
+	This is necessary because line numbers must match exactly,
+	but sed does not try to match a2 until after a1 has matched,
+	yet a1,a2 where a2 <= a1 is defined to be equivelent to
+	a1,a1+1
+
+Sat Feb 29 10:55:54 1992  David J. MacKenzie  (djm@nutrimat)
+
+	* sed.c (usage): Document long options as starting with `--'.
+
+Mon Dec  9 23:56:40 1991  David J. MacKenzie  (djm at wookumz.gnu.ai.mit.edu)
+
+	* sed.c: Include sys/types.h, for new regex.h.
+
+Tue Nov  5 02:16:01 1991  David J. MacKenzie  (djm at wookumz.gnu.ai.mit.edu)
+
+	* utils.c: Change NO_VFPRINTF to VPRINTF_MISSING, for
+	compatibility with autoconf.
+
+Mon Sep  2 22:02:40 1991  David J. MacKenzie  (djm at apple-gunkies)
+
+	* sed.c (compile_regex): Treat \ as a normal character when in
+	a char class.
+
+Thu Aug  8 00:15:33 1991  David J. MacKenzie  (djm at bleen)
+
+	* Version 1.08.
+
+	* sed.c (compile_filename): If reading a file fails, read
+	/dev/null instead.  It's what Unix and POSIX do, effectively.
+
+	* sed.c (compile_regex): The 'slash' character doesn't
+	terminate the regex if it's in a character class.
+
+	* sed.c (main): If given no args, or bad option, print usage
+	message.
+	(usage): New function.
+
+	* sed.c (execute_program): Amount written for 'P' command was
+	wrong.  From stephend@ksr.com (Stephen Davis).
+
+Wed Aug  7 16:51:14 1991  David J. MacKenzie  (djm at apple-gunkies)
+
+	* sed.c (append_pattern_space): Check for buffer full before
+	instead of after writing to buffer.  Don't need to test for
+	EOF initially anymore, due to the next change.
+	(execute_program): For 'n' and 'N' commands, if eof is reached
+	in input, quit the script like Unix sed does.
+	Fix memory allocation problems for 'a' and 'r' commands.
+	(compile_program): Fix off by one error in processing comments.
+	All of the above are from Tapani Tarvainen, tarvaine@tukki.jyu.fi.
+
+	* sed.c (setup_jump): Use isblank instead of testing for ' '
+	or '\t', for POSIX locales.
+
+	* utils.c (ck_strdup): Renamed from strdup.
+	* sed.c: Change callers.
+
+	* sed.c, utils.c: Clean up declarations and includes to get
+	rid of compiler warnings.
+
+	* sed.c (main): Add long-named options.  Don't complain if -n
+	is given twice.
+
+Fri Aug  2 12:33:16 1991  David J. MacKenzie  (djm at apple-gunkies)
+
+	* configure: Support +srcdir arg.  Create config.status and
+	remove it and Makefile if interrupted while creating them.
+	* Makefile.in: Change DESTDIR to prefix.
+
+Mon Jul 15 13:07:39 1991  David J. MacKenzie  (djm at wookumz.gnu.ai.mit.edu)
+
+	* sed.c (main): Add -V option to print version number.
+	(USAGE): Mention -V.
+
+Mon Jul  8 01:42:22 1991  David J. MacKenzie  (djm at geech.gnu.ai.mit.edu)
+
+	* sed.c: Define bcopy in terms of memcpy if STDC_HEADERS as
+	well as if USG.
+	(compile_filename): Don't glob filename (for 'r' and 'w'
+	commands).  Unix sed doesn't do it and it's not very useful,
+	since it can only match 0 or 1 files.
+	(execute_program): Change '\a' to 007 since some compilers
+	don't recognize \a.
+	* utils.c: New file; code moved from sed.c.
+	* Replace Makefile with Makefile.in and configure.
+	Update README.
+
+Tue Mar 26 13:00:48 EST 1991	Jay Fenlason (hack@gnu.ai.mit.edu)
+
+	* sed.c (match_address)  Added a trivial cast for portability.

+
+Basic Installation
+==================
+
+   Briefly, the shell commands `./configure; make; make install' should
+configure, build, and install this package.  The following
+more-detailed instructions are generic; see the `README' file for
+instructions specific to this package.  Some packages provide this
+`INSTALL' file but do not implement all of the features documented
+below.  The lack of an optional feature in a given package is not
+necessarily a bug.  More recommendations for GNU packages can be found
+in *note Makefile Conventions: (standards)Makefile Conventions.
+
+   The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation.  It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions.  Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, and a
+file `config.log' containing compiler output (useful mainly for
+debugging `configure').
+
+   It can also use an optional file (typically called `config.cache'
+and enabled with `--cache-file=config.cache' or simply `-C') that saves
+the results of its tests to speed up reconfiguring.  Caching is
+disabled by default to prevent problems with accidental use of stale
+cache files.
+
+   If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release.  If you are using the cache, and at
+some point `config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+   The file `configure.ac' (or `configure.in') is used to create
+`configure' by a program called `autoconf'.  You need `configure.ac' if
+you want to change it or regenerate `configure' using a newer version
+of `autoconf'.
+
+   The simplest way to compile this package is:
+
+  1. `cd' to the directory containing the package's source code and type
+     `./configure' to configure the package for your system.
+
+     Running `configure' might take a while.  While running, it prints
+     some messages telling which features it is checking for.
+
+  2. Type `make' to compile the package.
+
+  3. Optionally, type `make check' to run any self-tests that come with
+     the package, generally using the just-built uninstalled binaries.
+
+  4. Type `make install' to install the programs and any data files and
+     documentation.  When installing into a prefix owned by root, it is
+     recommended that the package be configured and built as a regular
+     user, and only the `make install' phase executed with root
+     privileges.
+
+  5. Optionally, type `make installcheck' to repeat any self-tests, but
+     this time using the binaries in their final installed location.
+     This target does not install anything.  Running this target as a
+     regular user, particularly if the prior `make install' required
+     root privileges, verifies that the installation completed
+     correctly.
+
+  6. You can remove the program binaries and object files from the
+     source code directory by typing `make clean'.  To also remove the
+     files that `configure' created (so you can compile the package for
+     a different kind of computer), type `make distclean'.  There is
+     also a `make maintainer-clean' target, but that is intended mainly
+     for the package's developers.  If you use it, you may have to get
+     all sorts of other programs in order to regenerate files that came
+     with the distribution.
+
+  7. Often, you can also type `make uninstall' to remove the installed
+     files again.  In practice, not all packages have tested that
+     uninstallation works correctly, even though it is required by the
+     GNU Coding Standards.
+
+  8. Some packages, particularly those that use Automake, provide `make
+     distcheck', which can by used by developers to test that all other
+     targets like `make install' and `make uninstall' work correctly.
+     This target is generally not run by end users.
+
+Compilers and Options
+=====================
+
+   Some systems require unusual options for compilation or linking that
+the `configure' script does not know about.  Run `./configure --help'
+for details on some of the pertinent environment variables.
+
+   You can give `configure' initial values for configuration parameters
+by setting variables in the command line or in the environment.  Here
+is an example:
+
+     ./configure CC=c99 CFLAGS=-g LIBS=-lposix
+
+   *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+   You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory.  To do this, you can use GNU `make'.  `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script.  `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.  This
+is known as a "VPATH" build.
+
+   With a non-GNU `make', it is safer to compile the package for one
+architecture at a time in the source code directory.  After you have
+installed the package for one architecture, use `make distclean' before
+reconfiguring for another architecture.
+
+   On MacOS X 10.5 and later systems, you can create libraries and
+executables that work on multiple system types--known as "fat" or
+"universal" binaries--by specifying multiple `-arch' options to the
+compiler but only a single `-arch' option to the preprocessor.  Like
+this:
+
+     ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+                 CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+                 CPP="gcc -E" CXXCPP="g++ -E"
+
+   This is not guaranteed to produce working output in all cases, you
+may have to build one architecture at a time and combine the results
+using the `lipo' tool if you have problems.
+
+Installation Names
+==================
+
+   By default, `make install' installs the package's commands under
+`/usr/local/bin', include files under `/usr/local/include', etc.  You
+can specify an installation prefix other than `/usr/local' by giving
+`configure' the option `--prefix=PREFIX', where PREFIX must be an
+absolute file name.
+
+   You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files.  If you
+pass the option `--exec-prefix=PREFIX' to `configure', the package uses
+PREFIX as the prefix for installing programs and libraries.
+Documentation and other data files still use the regular prefix.
+
+   In addition, if you use an unusual directory layout you can give
+options like `--bindir=DIR' to specify different values for particular
+kinds of files.  Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.  In general, the
+default for these options is expressed in terms of `${prefix}', so that
+specifying just `--prefix' will affect all of the other directory
+specifications that were not explicitly provided.
+
+   The most portable way to affect installation locations is to pass the
+correct locations to `configure'; however, many packages provide one or
+both of the following shortcuts of passing variable assignments to the
+`make install' command line to change installation locations without
+having to reconfigure or recompile.
+
+   The first method involves providing an override variable for each
+affected directory.  For example, `make install
+prefix=/alternate/directory' will choose an alternate location for all
+directory configuration variables that were expressed in terms of
+`${prefix}'.  Any directories that were specified during `configure',
+but not in terms of `${prefix}', must each be overridden at install
+time for the entire installation to be relocated.  The approach of
+makefile variable overrides for each directory variable is required by
+the GNU Coding Standards, and ideally causes no recompilation.
+However, some platforms have known limitations with the semantics of
+shared libraries that end up requiring recompilation when using this
+method, particularly noticeable in packages that use GNU Libtool.
+
+   The second method involves providing the `DESTDIR' variable.  For
+example, `make install DESTDIR=/alternate/directory' will prepend
+`/alternate/directory' before all installation names.  The approach of
+`DESTDIR' overrides is not required by the GNU Coding Standards, and
+does not work on platforms that have drive letters.  On the other hand,
+it does better at avoiding recompilation issues, and works well even
+when some directory options were not specified in terms of `${prefix}'
+at `configure' time.
+
+Optional Features
+=================
+
+   If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+   Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System).  The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+   For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+   Some packages offer the ability to configure how verbose the
+execution of `make' will be.  For these packages, running `./configure
+--enable-silent-rules' sets the default to minimal output, which can be
+overridden with `make V=1'; while running `./configure
+--disable-silent-rules' sets the default to verbose, which can be
+overridden with `make V=0'.
+
+Particular systems
+==================
+
+   On HP-UX, the default C compiler is not ANSI C compatible.  If GNU
+CC is not installed, it is recommended to use the following options in
+order to use an ANSI C compiler:
+
+     ./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
+
+and if that doesn't work, install pre-built binaries of GCC for HP-UX.
+
+   HP-UX `make' updates targets which have the same time stamps as
+their prerequisites, which makes it generally unusable when shipped
+generated files such as `configure' are involved.  Use GNU `make'
+instead.
+
+   On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
+parse its `<wchar.h>' header file.  The option `-nodtk' can be used as
+a workaround.  If GNU CC is not installed, it is therefore recommended
+to try
+
+     ./configure CC="cc"
+
+and if that doesn't work, try
+
+     ./configure CC="cc -nodtk"
+
+   On Solaris, don't put `/usr/ucb' early in your `PATH'.  This
+directory contains several dysfunctional programs; working variants of
+these programs are available in `/usr/bin'.  So, if you need `/usr/ucb'
+in your `PATH', put it _after_ `/usr/bin'.
+
+   On Haiku, software installed for all users goes in `/boot/common',
+not `/usr/local'.  It is recommended to use the following options:
+
+     ./configure --prefix=/boot/common
+
+Specifying the System Type
+==========================
+
+   There may be some features `configure' cannot figure out
+automatically, but needs to determine by the type of machine the package
+will run on.  Usually, assuming the package is built to be run on the
+_same_ architectures, `configure' can figure that out, but if it prints
+a message saying it cannot guess the machine type, give it the
+`--build=TYPE' option.  TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name which has the form:
+
+     CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+     OS
+     KERNEL-OS
+
+   See the file `config.sub' for the possible values of each field.  If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+   If you are _building_ compiler tools for cross-compiling, you should
+use the option `--target=TYPE' to select the type of system they will
+produce code for.
+
+   If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with `--host=TYPE'.
+
+Sharing Defaults
+================
+
+   If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists.  Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+   Variables not defined in a site shell script can be set in the
+environment passed to `configure'.  However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost.  In order to avoid this problem, you should set
+them in the `configure' command line, using `VAR=value'.  For example:
+
+     ./configure CC=/usr/local2/bin/gcc
+
+causes the specified `gcc' to be used as the C compiler (unless it is
+overridden in the site shell script).
+
+Unfortunately, this technique does not work for `CONFIG_SHELL' due to
+an Autoconf limitation.  Until the limitation is lifted, you can use
+this workaround:
+
+     CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash
+
+`configure' Invocation
+======================
+
+   `configure' recognizes the following options to control how it
+operates.
+
+`--help'
+`-h'
+     Print a summary of all of the options to `configure', and exit.
+
+`--help=short'
+`--help=recursive'
+     Print a summary of the options unique to this package's
+     `configure', and exit.  The `short' variant lists options used
+     only in the top level, while the `recursive' variant lists options
+     also present in any nested packages.
+
+`--version'
+`-V'
+     Print the version of Autoconf used to generate the `configure'
+     script, and exit.
+
+`--cache-file=FILE'
+     Enable the cache: use and save the results of the tests in FILE,
+     traditionally `config.cache'.  FILE defaults to `/dev/null' to
+     disable caching.
+
+`--config-cache'
+`-C'
+     Alias for `--cache-file=config.cache'.
+
+`--quiet'
+`--silent'
+`-q'
+     Do not print messages saying which checks are being made.  To
+     suppress all normal output, redirect it to `/dev/null' (any error
+     messages will still be shown).
+
+`--srcdir=DIR'
+     Look for the package's source code in directory DIR.  Usually
+     `configure' can determine that directory automatically.
+
+`--prefix=DIR'
+     Use DIR as the installation prefix.  *note Installation Names::
+     for more details, including other options available for fine-tuning
+     the installation locations.
+
+`--no-create'
+`-n'
+     Run the configure checks, but stop before creating any output
+     files.
+
+`configure' also accepts some other, not widely useful, options.  Run
+`configure --help' for more details.

+Sed 4.2.2
+
+* don't misbehave (truncate input) for lines of length 2^31 and longer
+
+* fix endless loop on incomplete multibyte sequences
+
+* -u also does unbuffered input, rather than unbuffered output only
+
+* New command `F' to print current input file name
+
+* sed -i, s///w, and the `w' and `W' commands also obey the --binary option
+  (and create CR/LF-terminated files if the option is absent)
+
+* --posix fails for scripts (or fragments as passed to the -e option) that
+  end in a backslash, as they are not portable.
+
+* New option -z (--null-data) to separate lines by ASCII NUL characters.
+
+* \x26 (and similar escaped sequences) produces a literal & in the
+  replacement argument of the s/// command, rather than including the
+  matched text.
+
+----------------------------------------------------------------------------
+Sed 4.2.1
+
+* fix parsing of s/[[[[[[[[[]//
+
+* security contexts are preserved by -i too under SELinux
+
+* temporary files for sed -i are not made group/world-readable until
+  they are complete
+
+----------------------------------------------------------------------------
+Sed 4.2
+
+* now released under GPLv3
+
+* added a new extension `z` to clear pattern space even in the presence
+of invalid multibyte sequences
+
+* a preexisting GNU gettext installation is needed in order to compile
+GNU sed with NLS support
+
+* new option --follow-symlinks, available when editing a file in-place.
+This option may not be available on some systems (in this case, the
+option will *not* be a no-op; it will be completely unavailable).
+In the future, the option may be added as a no-op on systems without
+symbolic links at all, since in this case a no-op is effectively
+indistinguishable from a correct implementation.
+
+* hold-space is reset between different files in -i and -s modes.
+
+* multibyte processing fixed
+
+* the following GNU extensions are turned off by --posix: options [iImMsSxX]
+in the `s' command, address kinds `FIRST~STEP' and `ADDR1,+N' and `ADDR1,~N',
+line address 0, `e' or `z' commands, text between an `a' or `c' or `i'
+command and the following backslash, arguments to the `l' command.
+--posix disables all extensions to regular expressions.
+
+* fixed bug in 'i\' giving a segmentation violation if given alone.
+
+* much improved portability
+
+* much faster in UTF-8 locales
+
+* will correctly replace ACLs when using -i
+
+* will now accept NUL bytes for `.'
+
+----------------------------------------------------------------------------
+Sed 4.1.5
+
+* fix parsing of a negative character class not including a closed bracket,
+  like [^]] or [^]a-z].
+
+* fix parsing of [ inside an y command, like y/[/A/.
+
+* output the result of commands a, r, R when a q command is found.
+
+----------------------------------------------------------------------------
+Sed 4.1.4
+
+* \B correctly means "not on a word boundary" rather than "inside a word"
+
+* bugfixes for platform without internationalization
+
+* more thorough testing framework for tarballs (`make full-distcheck')
+
+----------------------------------------------------------------------------
+Sed 4.1.3
+
+* regex addresses do not use leftmost-longest matching.  In other words,
+  /.\+/ only looks for a single character, and does not try to find as
+  many of them as possible like it used to do.
+
+* added a note to BUGS and the manual about changed interpretation
+  of `s|abc\|def||', and about localization issues.
+
+* fixed --disable-nls build problems on Solaris.
+
+* fixed `make check' in non-English locales.
+
+* `make check' tests the regex library by default if the included regex
+  is used (regex tests had to be enabled separately up to now).
+
+----------------------------------------------------------------------------
+Sed 4.1.2
+
+* fix bug in 'y' command in multi-byte character sets
+
+* fix severe bug in parsing of ranges with an embedded open bracket
+
+* fix off-by-one error when printing a "bad command" error
+
+----------------------------------------------------------------------------
+Sed 4.1.1
+
+* preserve permissions of in-place edited files
+
+* yield an error when running -i on terminals or other non regular files
+
+* do not interpret - as stdin when running in in-place editing mode
+
+* fix bug that prevented 's' command modifiers from working
+
+----------------------------------------------------------------------------
+Sed 4.1
+
+* // matches the last regular expression even in POSIXLY_CORRECT mode.
+
+* change the way we treat lines which are not terminated by a newline.
+Such lines are printed without the terminating newline (as before)
+but as soon as more text is sent to the same output stream, the
+missing newline is printed, so that the two lines don't concatenate.
+The behavior is now independent from POSIXLY_CORRECT because POSIX
+actually has undefined behavior in this case, and the new implementation
+arguably gives the ``least expected surprise''.  Thanks to Stepan
+Kasal for the implementation.
+
+* documentation improvements, with updated references to the POSIX.2
+specification
+
+* error messages on I/O errors are better, and -i does not leave temporary
+files around (e.g. when running ``sed -i'' on a directory).
+
+* escapes are accepted in the y command (for example: y/o/\n/ transforms
+o's into newlines)
+
+* -i option tries to set the owner and group to the same as the input file
+
+* `L' command is deprecated and will be removed in sed 4.2.
+
+* line number addresses are processed differently -- this is supposedly
+conformant to POSIX and surely more idiot-proof.  Line number addresses
+are not affected by jumping around them: they are activated and
+deactivated exactly where the script says, while previously
+    5,8b
+    1,5d
+would actually delete lines 1,2,3,4 and 9 (!).
+
+* multibyte characters are taken in consideration to compute the
+operands of s and y, provided you set LC_CTYPE correctly.  They are
+also considered by \l, \L, \u, \U, \E.
+
+* [\n] matches either backslash or 'n' when POSIXLY_CORRECT.
+
+* new option --posix, disables all GNU extensions.  POSIXLY_CORRECT only
+disables GNU extensions that violate the POSIX standard.
+
+* options -h and -V are not supported anymore, use --help and --version.
+
+* removed documentation for \s and \S which worked incorrectly
+
+* restored correct behavior for \w and \W: match [[:alnum:]_] and
+[^[:alnum:]_] (they used to match [[:alpha:]_] and [^[:alpha:]_]
+
+* the special address 0 can only be used in 0,/RE/ or 0~STEP addresses;
+other cases give an error (you are hindering portability for no reason
+if specifying 0,N and you are giving a dead command if specifying 0
+alone).
+
+* when a \ is used to escape the character that would terminate an operand
+of the s or y commands, the backslash is removed before the regex is
+compiled.  This is left undefined by POSIX; this behavior makes `s+x\+++g'
+remove occurrences of `x+', consistently with `s/x\///g'.  (However, if
+you enjoy yourself trying `s*x\***g', sed will use the `x*' regex, and you
+won't be able to pass down `x\*' while using * as the delimiter; ideas on
+how to simplify the parser in this respect, and/or gain more coherent
+semantics, are welcome).
+
+
+----------------------------------------------------------------------------
+Sed 4.0.9
+
+* 0 address behaves correctly in single-file (-i and -s) mode.
+
+* documentation improvements.
+
+* tested with many hosts and compilers.
+
+* updated regex matcher from upstream, with many bugfixes and speedups.
+
+* the `N' command's feature that is detailed in the BUGS file was disabled
+by the first change below in sed 4.0.8.  The behavior has now been
+restored, and is only enabled if POSIXLY_CORRECT behavior is not
+requested.
+
+----------------------------------------------------------------------------
+Sed 4.0.8
+
+* fix `sed n' printing the last line twice.
+
+* fix incorrect error message for invalid character classes.
+
+* fix segmentation violation with repeated empty subexpressions.
+
+* fix incorrect parsing of ^ after escaped (.
+
+* more comprehensive test suite (and with many expected failures...)
+

+Sed 4.0.7

+* fixed bug in s///Np: was printing even if less than N matches were
+found.
+
+* fixed infinite loop on s///N when LHS matched a null string and
+there were not enough matches in pattern space
+
+* behavior of s///N is consistent with s///g when the LHS can match
+a null string (and the infinite loop did not happen :-)
+
+* updated some translations
+
+----------------------------------------------------------------------------
+Sed 4.0.6
+
+* added parameter to `v' for the version of sed that is expected.
+
+* configure switch --without-included-regex to use the system regex matcher
+
+* fix for -i option under Cygwin
+
+----------------------------------------------------------------------------
+Sed 4.0.5
+
+* portability fixes
+
+* improvements to some error messages (e.g. y/abc/defg/ incorrectly said
+`excess characters after command' instead of `y arguments have different
+lengths')
+
+* `a', `i', `l', `L', `r' accept two addresses except in POSIXLY_CORRECT
+mode.  Only `q' and `Q' do not accept two addresses in standard (GNU) mode.
+
+----------------------------------------------------------------------------
+Sed 4.0.4
+
+* documentation fixes
+
+* update regex matcher
+
+----------------------------------------------------------------------------
+Sed 4.0.3
+
+* fix packaging problem (two missing translation catalogs)
+
+----------------------------------------------------------------------------
+Sed 4.0.2
+
+* more translations
+
+* fix build problems (vpath builds and bootstrap builds)
+
+----------------------------------------------------------------------------
+Sed 4.0.1
+
+* Remove last vestiges of super-sed
+
+* man page automatically built
+
+* more translations provided
+
+* portability improvements
+
+----------------------------------------------------------------------------
+Sed 4.0
+
+* Update regex matcher
+
+----------------------------------------------------------------------------
+Sed 3.96
+
+* `y' command supports multibyte character sets
+
+* Update regex matcher
+
+----------------------------------------------------------------------------
+Sed 3.95
+
+* `R' command reads a single line from a file.
+
+* CR-LF pairs are always ignored under Windows, even if (under Cygwin)
+a disk is mounted as binary.
+
+* More attention to errors on stdout
+
+* New `W' command to write first line of pattern space to a file
+
+* Can customize line wrap width on single `l' commands
+
+* `L' command formats and reflows paragraphs like `fmt' does.
+
+* The test suite makefiles are better organized (this change is
+transparent however).
+
+* Compiles and bootstraps out-of-the-box under MinGW32 and Cygwin.
+
+* Optimizes cases when pattern space is truncated at its start or at
+its end by `D' or by a substitution command with an empty RHS.
+For example scripts like this,
+
+    seq 1 10000 | tr \\n \  | ./sed ':a; s/^[0-9][0-9]* //; ta'
+
+whose behavior was quadratic with previous versions of sed, have
+now linear behavior.
+
+* New command `e' to pipe the output of a command into the output
+of sed.
+
+* New option `e' to pass the output of the `s' command through the
+Bourne shell and get the result into pattern space.
+
+* Switched to obstacks in the parser -- less memory-related bugs
+(there were none AFAIK but you never know) and less memory usage.
+
+* New option -i, to support in-place editing a la Perl.  Usually one
+had to use ed or, for more complex tasks, resort to Perl; this is
+not necessary anymore.
+
+* Dumped buffering code.  The performance loss is 10%, but it caused
+bugs in systems with CRLF termination.  The current solution is
+not definitive, though.
+
+* Bug fix: Made the behavior of s/A*/x/g (i.e. `s' command with a
+possibly empty LHS) more consistent:
+
+       pattern               GNU sed 3.x       GNU sed 4.x
+        B                      xBx               xBx
+        BC                     xBxCx             xBxCx
+        BAC                    xBxxCx            xBxCx
+        BAAC                   xBxxCx            xBxCx
+
+* Bug fix: the // empty regular expressions now refers to the last
+regular expression that was matched, rather than to the last
+regular expression that was compiled.  This richer behavior seems
+to be the correct one (albeit neither one is POSIXLY_CORRECT).
+
+* Check for invalid backreferences in the RHS of the `s' command
+(e.g. s/1234/\1/)
+
+* Support for \[lLuUE] in the RHS of the `s' command like in Perl.
+
+* New regular expression matcher
+
+* Bug fix: if a file was redirected to be stdin, sed did not consume
+it.  So
+      (sed d; sed G) < TESTFILE
+
+double-spaced TESTFILE, while the equivalent `useless use of cat'
+      cat TESTFILE | (sed d; sed G)
+
+printed nothing (which is the correct behavior).  A test for this
+bug was added to the test suite.
+
+* The documentation is now much better, with a few examples provided,
+and a thorough description of regular expressions.  The manual often
+refers to "GNU extensions", but if they are described here they are
+specific to this version.
+
+* Documented command-line option:
+  -r, --regexp-extended
+    Use extended regexps -- e.g. (abc+) instead of \(abc\+\)
+
+* Added feature to the `w' command and to the `w' option of the `s'
+command: if the file name is /dev/stderr, it means the standard
+error (inspired by awk); and similarly for /dev/stdout.  This is
+disabled if POSIXLY_CORRECT is set.
+
+* Added `m' and `M' modifiers to `s' command for multi-line
+matching (Perl-style); in addresses, only `M' works.
+
+* Added `Q' command for `silent quit'; added ability to pass
+an exit code from a sed script to the caller.
+
+* Added `T' command for `branch if failed'.
+
+* Added `v' command, which is a do-nothing intended to fail on
+seds that do not support GNU sed 4.0's extensions.
+
+----------------------------------------------------------------------------
+Sed 3.02.80
+
+* Started new version nomenclature for pre-3.03 releases.  (I'm being
+pessimistic in assuming that .90 won't give me enough breathing room.)
+
+* Bug fixes: the regncomp()/regnexec() interfaces proved to be inadequate to
+properly handle expressions such as "s/\</#/g".  Re-abstracted the regex
+code in the sed/ tree, and now use the re_search_2() interface to the GNU
+regex routines.  This change also fixed a bug where /./ did not match the
+NUL character.  Had the glibc folk fix a bug in lib/regex.c where
+'s/0*\([0-9][0-9]\)/X\1X/' failed to match on input "002".
+
+* Added new command-line options:
+  -u, --unbuffered
+    Do not attempt to read-ahead more than required; do not buffer stdout.
+  -l N, --line-length=N
+    Specify the desired line-wrap length for the `l' command.
+    A length of "0" means "never wrap".
+
+* New internationalization translations added: fr ru de it el sk pt_BR sv
+(plus nl from 3.02a).
+
+* The s/// command now understands the following escapes
+(in both halves):
+	\a	an "alert" (BEL)
+	\f	a form-feed
+	\n	a newline
+	\r	a carriage-return
+	\t	a horizontal tab
+	\v	a vertical tab
+	\oNNN	a character with the octal value NNN
+	\dNNN	a character with the decimal value NNN
+	\xNN	a character with the hexadecimal value NN
+This behavior is disabled if POSIXLY_CORRECT is set, at least for the
+time being (until I can be convinced that this behavior does not violate
+the POSIX standard).  (Incidentally, \b (backspace) was omitted because
+of the conflict with the existing "word boundary" meaning. \ooo octal
+format was omitted because of the conflict with backreference syntax.)
+
+* If POSIXLY_CORRECT is set, the empty RE // now is the null match
+instead of "repeat the last REmatch".  As far as I can tell
+this behavior is mandated by POSIX, but it would break too many
+legacy sed scripts to blithely change GNU sed's default behavior.
+
+----------------------------------------------------------------------------
+Sed 3.02a
+
+* Added internationalization support, and an initial (already out of date)
+set of Dutch message translations (both provided by Erick Branderhorst).
+
+* Added support for scripts like:
+ sed -e 1ifoo -e '$abar'
+(note no need for \ <newline> after a, i, and c commands).
+Also, conditionally (on NO_INPUT_INDENT) added
+experimental support for skipping leading whitespace on
+each {a,i,c} input line.
+
+* Added addressing of the form:
+ /foo/,+5 p (print from foo to 5th line following)
+ /foo/,~5 p (print from foo to next line whose line number is a multiple of 5)
+The first address of these can be any of the previously existing
+addressing types; the +N and ~N forms are only allowed as the
+second address of a range.
+
+* Added support for pseudo-address "0" as the first address in an
+address-range, simplifying scripts which happen to match the end
+address on the first line of input.  For example, a script
+which deletes all lines from the beginning of the file to the
+first line which contains "foo" is now simply "sed 0,/foo/d",
+whereas before one had to go through contortions to deal with
+the possibility that "foo" might appear on the first line of
+the input.
+
+* Made NUL characters in regexps work "correctly" --- i.e., a NUL
+in a RE matches a NUL; it does not prematurely terminate the RE.
+(This only works in -f scripts, as the POSIX.1 exec*() interface
+only passes NUL-terminated strings, and so sed will only be able
+to see up to the first NUL in any -e scriptlet.)
+
+* Wherever a `;' is accepted as a command terminator, also allow a `}'
+or a `#' to appear.  (This allows for less cluttered-looking scripts.)
+
+* Lots of internal changes that are only relevant to source junkies
+and development testing.  Some of which might cause imperceptible
+performance improvements.
+
+----------------------------------------------------------------------------
+Sed 3.02
+
+* Fixed a bug in the parsing of character classes (e.g., /[[:space:]]/).
+Corrected an omission in djgpp/Makefile.am and an improper dependency
+in testsuite/Makefile.am.
+
+----------------------------------------------------------------------------
+Sed 3.01
+
+* This version of sed mainly contains bug fixes and portability
+enhancements, plus performance enhancements related to sed's handling
+of input files.  Due to excess performance penalties, I have reverted
+(relative to 3.00) to using regex.c instead of the rx package for
+regular expression handling, at the expense of losing true POSIX.2
+BRE compatibility.  However, performance related to regular expression
+handling *still* needs a fair bit of work.
+
+* One new feature has been added: regular expressions may be followed
+with an "I" directive ("i" was taken [the "i"nsert command]) to
+indicate that the regexp should be matched in a case-insensitive
+manner.  Also of note are a new organization to the source code,
+new documentation, and a new maintainer.
+
+----------------------------------------------------------------------------
+Sed 3.0
+
+* This version of sed passes the new test-suite donated by
+Jason Molenda.
+
+* Overall performance has been improved in the following sense: Sed 3.0
+is often slightly slower than sed 2.05.  On a few scripts, though, sed
+2.05 was so slow as to be nearly useless or to use up unreasonable
+amounts of memory.  These problems have been fixed and in such cases,
+sed 3.0 should have acceptable performance.

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
+# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory.  The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run.  This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+#    fails when called from a subdirectory if $ac_aux_dir is relative

+#    fails if $ac_aux_dir is absolute,
+#    fails when called from a subdirectory in a VPATH build with
+#          a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir.  In an in-source build this is usually
+# harmless because $srcdir is '.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,

+# This will work as long as MISSING is not called from configure, because

+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.

+/* _GL_WARN_ON_USE (function, "literal string") issues a declaration
+   for FUNCTION which will then trigger a compiler warning containing
+   the text of "literal string" anywhere that function is called, if
+   supported by the compiler.  If the compiler does not support this
+   feature, the macro expands to an unused extern declaration.
+
+   This macro is useful for marking a function as a potential
+   portability trap, with the intent that "literal string" include
+   instructions on the replacement function that should be used
+   instead.  However, one of the reasons that a function is a
+   portability trap is if it has the wrong signature.  Declaring
+   FUNCTION with a different signature in C is a compilation error, so
+   this macro must use the same type as any existing declaration so
+   that programs that avoid the problematic FUNCTION do not fail to
+   compile merely because they included a header that poisoned the
+   function.  But this implies that _GL_WARN_ON_USE is only safe to
+   use if FUNCTION is known to already have a declaration.  Use of
+   this macro implies that there must not be any other macro hiding
+   the declaration of FUNCTION; but undefining FUNCTION first is part
+   of the poisoning process anyway (although for symbols that are
+   provided only via a macro, the result is a compilation error rather
+   than a warning containing "literal string").  Also note that in
+   C++, it is only safe to use if FUNCTION has no overloads.
+
+   For an example, it is possible to poison 'getline' by:
+   - adding a call to gl_WARN_ON_USE_PREPARE([[#include <stdio.h>]],
+     [getline]) in configure.ac, which potentially defines
+     HAVE_RAW_DECL_GETLINE
+   - adding this code to a header that wraps the system <stdio.h>:
+     #undef getline
+     #if HAVE_RAW_DECL_GETLINE
+     _GL_WARN_ON_USE (getline, "getline is required by POSIX 2008, but"
+       "not universally present; use the gnulib module getline");
+     #endif
+
+   It is not possible to directly poison global variables.  But it is
+   possible to write a wrapper accessor function, and poison that
+   (less common usage, like &environ, will cause a compilation error
+   rather than issue the nice warning, but the end result of informing
+   the developer about their portability problem is still achieved):
+   #if HAVE_RAW_DECL_ENVIRON
+   static char ***rpl_environ (void) { return &environ; }
+   _GL_WARN_ON_USE (rpl_environ, "environ is not always properly declared");

+
+Run each Texinfo or LaTeX FILE through TeX in turn until all
+cross-references are resolved, building all indices.  The directory
+containing each FILE is searched for included files.  The suffix of FILE
+is used to determine its language (LaTeX or Texinfo).
+
+Makeinfo is used to perform Texinfo macro expansion before running TeX
+when needed.
+
+Operation modes:
+  -b, --batch         no interaction
+  -c, --clean         remove all auxiliary files
+  -D, --debug         turn on shell debugging (set -x)
+  -h, --help          display this help and exit successfully
+  -o, --output=OFILE  leave output in OFILE (implies --clean);
+                      Only one input FILE may be specified in this case
+  -q, --quiet         no output unless errors (implies --batch)
+  -s, --silent        same as --quiet
+  -v, --version       display version information and exit successfully
+  -V, --verbose       report on what is done
+
+TeX tuning:
+  -@                   use @input instead of \input; for preloaded Texinfo
+  -e, -E, --expand     force macro expansion using makeinfo
+  -I DIR               search DIR for Texinfo files
+  -l, --language=LANG  specify the LANG of FILE (LaTeX or Texinfo)
+  -p, --pdf            use pdftex or pdflatex for processing
+  -t, --texinfo=CMD    insert CMD after @setfilename in copy of input file
+                       multiple values accumulate
+
+The values of the BIBTEX, LATEX (or PDFLATEX), MAKEINDEX, MAKEINFO,
+TEX (or PDFTEX), and TEXINDEX environment variables are used to run

+%
+% Please try the latest version of texinfo.tex before submitting bug
+% reports; you can get the latest version from:
+%   http://ftp.gnu.org/gnu/texinfo/ (the Texinfo release area), or
+%   http://ftpmirror.gnu.org/texinfo/ (same, via a mirror), or
+%   http://www.gnu.org/software/texinfo/ (the Texinfo home page)
+% The texinfo.tex in any given distribution could well be out

+%
+% Send bug reports to bug-texinfo@gnu.org.  Please include including a

+%
+% To process a Texinfo manual with TeX, it's most reliable to use the
+% texi2dvi shell script that comes with the distribution.  For a simple
+% manual foo.texi, however, you can get away with this:
+%   tex foo.texi
+%   texindex foo.??
+%   tex foo.texi
+%   tex foo.texi
+%   dvips foo.dvi -o  # or whatever; this makes foo.ps.
+% The extra TeX runs get the cross-reference information correct.
+% Sometimes one run after texindex suffices, and sometimes you need more
+% than two; texi2dvi does it as many times as necessary.
+%
+% It is possible to adapt texinfo.tex for other languages, to some
+% extent.  You can get the existing language-specific files from the
+% full Texinfo distribution.

+% @multitable macros
+% Amy Hendrickson, 8/18/94, 3/6/96
+%
+% @multitable ... @end multitable will make as many columns as desired.
+% Contents of each column will wrap at width given in preamble.  Width
+% can be specified either with sample text given in a template line,
+% or in percent of \hsize, the current width of text on page.
+
+% Table can continue over pages but will only break between lines.
+
+% To make preamble:
+%
+% Either define widths of columns in terms of percent of \hsize:
+%   @multitable @columnfractions .25 .3 .45
+%   @item ...
+%
+%   Numbers following @columnfractions are the percent of the total
+%   current hsize to be used for each column. You may use as many
+%   columns as desired.
+
+
+% Or use a template:
+%   @multitable {Column 1 template} {Column 2 template} {Column 3 template}
+%   @item ...
+%   using the widest term desired in each column.
+
+% Each new table line starts with @item, each subsequent new column
+% starts with @tab. Empty columns may be produced by supplying @tab's
+% with nothing between them for as many times as empty columns are needed,
+% ie, @tab@tab@tab will produce two empty columns.
+
+% @item, @tab do not need to be on their own lines, but it will not hurt
+% if they are.
+
+% Sample multitable:
+
+%   @multitable {Column 1 template} {Column 2 template} {Column 3 template}
+%   @item first col stuff @tab second col stuff @tab third col
+%   @item
+%   first col stuff
+%   @tab
+%   second col stuff
+%   @tab
+%   third col
+%   @item first col stuff @tab second col stuff
+%   @tab Many paragraphs of text may be used in any column.
+%
+%         They will wrap at the width determined by the template.
+%   @item@tab@tab This will be in third column.
+%   @end multitable
+
+% Default dimensions may be reset by user.
+% @multitableparskip is vertical space between paragraphs in table.
+% @multitableparindent is paragraph indent in table.
+% @multitablecolmargin is horizontal space to be left between columns.
+% @multitablelinespace is space to leave between table items, baseline
+%                                                            to baseline.

+@node Introduction
+@chapter Introduction
+
+@cindex Stream editor
+@command{sed} is a stream editor.
+A stream editor is used to perform basic text
+transformations on an input stream
+(a file or input from a pipeline).
+While in some ways similar to an editor which
+permits scripted edits (such as @command{ed}),
+@command{sed} works by making only one pass over the
+input(s), and is consequently more efficient.
+But it is @command{sed}'s ability to filter text in a pipeline
+which particularly distinguishes it from other types of
+editors.
+
+
+@node Invoking sed
+@chapter Invocation
+
+Normally @command{sed} is invoked like this:
+
+@example
+sed SCRIPT INPUTFILE...
+@end example
+
+The full format for invoking @command{sed} is:
+
+@example
+sed OPTIONS... [SCRIPT] [INPUTFILE...]
+@end example
+
+If you do not specify @var{INPUTFILE}, or if @var{INPUTFILE} is @file{-},
+@command{sed} filters the contents of the standard input.  The @var{script}
+is actually the first non-option parameter, which @command{sed} specially
+considers a script and not an input file if (and only if) none of the
+other @var{options} specifies a script to be executed, that is if neither
+of the @option{-e} and @option{-f} options is specified.
+
+@command{sed} may be invoked with the following command-line options:
+
+@table @code
+@item --version
+@opindex --version
+@cindex Version, printing
+Print out the version of @command{sed} that is being run and a copyright notice,
+then exit.
+
+@item --help
+@opindex --help
+@cindex Usage summary, printing
+Print a usage message briefly summarizing these command-line options
+and the bug-reporting address,
+then exit.
+
+@item -n
+@itemx --quiet
+@itemx --silent
+@opindex -n
+@opindex --quiet
+@opindex --silent
+@cindex Disabling autoprint, from command line
+By default, @command{sed} prints out the pattern space
+at the end of each cycle through the script (@pxref{Execution Cycle, ,
+How @code{sed} works}).
+These options disable this automatic printing,
+and @command{sed} only produces output when explicitly told to
+via the @code{p} command.
+
+@item -e @var{script}
+@itemx --expression=@var{script}
+@opindex -e
+@opindex --expression
+@cindex Script, from command line
+Add the commands in @var{script} to the set of commands to be
+run while processing the input.
+
+@item -f @var{script-file}
+@itemx --file=@var{script-file}
+@opindex -f
+@opindex --file
+@cindex Script, from a file
+Add the commands contained in the file @var{script-file}
+to the set of commands to be run while processing the input.
+
+@item -i[@var{SUFFIX}]
+@itemx --in-place[=@var{SUFFIX}]
+@opindex -i
+@opindex --in-place
+@cindex In-place editing, activating
+@cindex @value{SSEDEXT}, in-place editing
+This option specifies that files are to be edited in-place.
+@value{SSED} does this by creating a temporary file and
+sending output to this file rather than to the standard
+output.@footnote{This applies to commands such as @code{=},
+@code{a}, @code{c}, @code{i}, @code{l}, @code{p}.  You can
+still write to the standard output by using the @code{w}
+@cindex @value{SSEDEXT}, @file{/dev/stdout} file
+or @code{W} commands together with the @file{/dev/stdout}
+special file}.
+
+This option implies @option{-s}.
+
+When the end of the file is reached, the temporary file is
+renamed to the output file's original name.  The extension,
+if supplied, is used to modify the name of the old file
+before renaming the temporary file, thereby making a backup
+copy@footnote{Note that @value{SSED} creates the backup
+file whether or not any output is actually changed.}).
+
+@cindex In-place editing, Perl-style backup file names
+This rule is followed: if the extension doesn't contain a @code{*},
+then it is appended to the end of the current filename as a
+suffix; if the extension does contain one or more @code{*}
+characters, then @emph{each} asterisk is replaced with the
+current filename.  This allows you to add a prefix to the
+backup file, instead of (or in addition to) a suffix, or
+even to place backup copies of the original files into another
+directory (provided the directory already exists).
+
+If no extension is supplied, the original file is
+overwritten without making a backup.
+
+@item -l @var{N}
+@itemx --line-length=@var{N}
+@opindex -l
+@opindex --line-length
+@cindex Line length, setting
+Specify the default line-wrap length for the @code{l} command.
+A length of 0 (zero) means to never wrap long lines.  If
+not specified, it is taken to be 70.
+
+@item --posix
+@opindex --posix
+@cindex @value{SSEDEXT}, disabling
+@value{SSED} includes several extensions to @acronym{POSIX}
+sed.  In order to simplify writing portable scripts, this
+option disables all the extensions that this manual documents,
+including additional commands.
+@cindex @code{POSIXLY_CORRECT} behavior, enabling
+Most of the extensions accept @command{sed} programs that
+are outside the syntax mandated by @acronym{POSIX}, but some
+of them (such as the behavior of the @command{N} command

+When such a distinction is made---as is the case for MS-DOS, Windows,

+on the command line is a symbolic link, @command{sed} will

+@cindex Script structure
+A @command{sed} program consists of one or more @command{sed} commands,
+passed in by one or more of the
+@option{-e}, @option{-f}, @option{--expression}, and @option{--file}
+options, or the first non-option argument if zero of these
+options are used.
+This document will refer to ``the'' @command{sed} script;
+this is understood to mean the in-order catenation
+of all of the @var{script}s and @var{script-file}s passed in.
+
+Commands within a @var{script} or @var{script-file} can be
+separated by semicolons (@code{;}) or newlines (ASCII 10).
+Some commands, due to their syntax, cannot be followed by semicolons
+working as command separators and thus should be terminated
+with newlines or be placed at the end of a @var{script} or @var{script-file}.
+Commands can also be preceded with optional non-significant
+whitespace characters.
+
+Each @code{sed} command consists of an optional address or
+address range, followed by a one-character command name
+and any additional command-specific code.

+@section How @command{sed} Works
+
+@cindex Buffer spaces, pattern and hold
+@cindex Spaces, pattern and hold
+@cindex Pattern space, definition
+@cindex Hold space, definition
+@command{sed} maintains two data buffers: the active @emph{pattern} space,
+and the auxiliary @emph{hold} space. Both are initially empty.
+
+@command{sed} operates by performing the following cycle on each
+line of input: first, @command{sed} reads one line from the input
+stream, removes any trailing newline, and places it in the pattern space.
+Then commands are executed; each command can have an address associated
+to it: addresses are a kind of condition code, and a command is only
+executed if the condition is verified before the command is to be
+executed.
+
+When the end of the script is reached, unless the @option{-n} option
+is in use, the contents of pattern space are printed out to the output
+stream, adding back the trailing newline if it was removed.@footnote{Actually,
+if @command{sed} prints a line without the terminating newline, it will
+nevertheless print the missing newline as soon as more text is sent to
+the same output stream, which gives the ``least expected surprise''
+even though it does not make commands like @samp{sed -n p} exactly
+identical to @command{cat}.} Then the next cycle starts for the next
+input line.
+
+Unless special commands (like @samp{D}) are used, the pattern space is
+deleted between two cycles. The hold space, on the other hand, keeps
+its data between cycles (see commands @samp{h}, @samp{H}, @samp{x},
+@samp{g}, @samp{G} to move data between both buffers).
+
+
+@node Addresses
+@section Selecting lines with @command{sed}
+@cindex Addresses, in @command{sed} scripts
+@cindex Line selection
+@cindex Selecting lines to process
+
+Addresses in a @command{sed} script can be in any of the following forms:
+@table @code
+@item @var{number}
+@cindex Address, numeric
+@cindex Line, selecting by number
+Specifying a line number will match only that line in the input.
+(Note that @command{sed} counts lines continuously across all input files
+unless @option{-i} or @option{-s} options are specified.)
+
+@item @var{first}~@var{step}
+@cindex @acronym{GNU} extensions, @samp{@var{n}~@var{m}} addresses
+This @acronym{GNU} extension matches every @var{step}th line
+starting with line @var{first}.
+In particular, lines will be selected when there exists
+a non-negative @var{n} such that the current line-number equals
+@var{first} + (@var{n} * @var{step}).
+Thus, to select the odd-numbered lines,
+one would use @code{1~2};
+to pick every third line starting with the second, @samp{2~3} would be used;
+to pick every fifth line starting with the tenth, use @samp{10~5};
+and @samp{50~0} is just an obscure way of saying @code{50}.
+
+@item $
+@cindex Address, last line
+@cindex Last line, selecting
+@cindex Line, selecting last
+This address matches the last line of the last file of input, or
+the last line of each file when the @option{-i} or @option{-s} options
+are specified.
+
+@item /@var{regexp}/
+@cindex Address, as a regular expression
+@cindex Line, selecting by regular expression match
+This will select any line which matches the regular expression @var{regexp}.
+If @var{regexp} itself includes any @code{/} characters,
+each must be escaped by a backslash (@code{\}).
+
+@cindex empty regular expression
+@cindex @value{SSEDEXT}, modifiers and the empty regular expression
+The empty regular expression @samp{//} repeats the last regular
+expression match (the same holds if the empty regular expression is
+passed to the @code{s} command).  Note that modifiers to regular expressions
+are evaluated when the regular expression is compiled, thus it is invalid to
+specify them together with the empty regular expression.
+
+@item \%@var{regexp}%
+(The @code{%} may be replaced by any other single character.)
+
+@cindex Slash character, in regular expressions
+This also matches the regular expression @var{regexp},
+but allows one to use a different delimiter than @code{/}.
+This is particularly useful if the @var{regexp} itself contains
+a lot of slashes, since it avoids the tedious escaping of every @code{/}.
+If @var{regexp} itself includes any delimiter characters,
+each must be escaped by a backslash (@code{\}).
+
+@item /@var{regexp}/I
+@itemx \%@var{regexp}%I
+@cindex @acronym{GNU} extensions, @code{I} modifier
+@ifset PERL
+@cindex Perl-style regular expressions, case-insensitive
+@end ifset
+The @code{I} modifier to regular-expression matching is a @acronym{GNU}
+extension which causes the @var{regexp} to be matched in
+a case-insensitive manner.
+

+@itemx \%@var{regexp}%M
+@cindex @value{SSEDEXT}, @code{M} modifier
+@ifset PERL
+@cindex Perl-style regular expressions, multiline
+@end ifset
+The @code{M} modifier to regular-expression matching is a @value{SSED}
+extension which directs @value{SSED} to match the regular expression
+in @cite{multi-line} mode.  The modifier causes @code{^} and @code{$} to
+match respectively (in addition to the normal behavior) the empty string
+after a newline, and the empty string before a newline.  There are
+special character sequences
+@ifset PERL
+(@code{\A} and @code{\Z} in Perl mode, @code{\`} and @code{\'}
+in basic or extended regular expression modes)
+@end ifset
+@ifclear PERL
+(@code{\`} and @code{\'})
+@end ifclear
+which always match the beginning or the end of the buffer.
+In addition,
+@ifset PERL
+just like in Perl mode without the @code{S} modifier,
+@end ifset
+the period character does not match a new-line character in
+multi-line mode.
+
+@ifset PERL
+@item /@var{regexp}/S
+@itemx \%@var{regexp}%S
+@cindex @value{SSEDEXT}, @code{S} modifier
+@cindex Perl-style regular expressions, single line
+The @code{S} modifier to regular-expression matching is only valid
+in Perl mode and specifies that the dot character (@code{.}) will
+match the newline character too.  @code{S} stands for @cite{single-line}.
+@end ifset
+
+@ifset PERL
+@item /@var{regexp}/X
+@itemx \%@var{regexp}%X
+@cindex @value{SSEDEXT}, @code{X} modifier
+@cindex Perl-style regular expressions, extended
+The @code{X} modifier to regular-expression matching is also
+valid in Perl mode only.  If it is used, whitespace in the
+pattern (other than in a character class) and
+characters between a @kbd{#} outside a character class and the
+next newline character are ignored. An escaping backslash
+can be used to include a whitespace or @kbd{#} character as part
+of the pattern.
+@end ifset
+@end table
+
+If no addresses are given, then all lines are matched;
+if one address is given, then only lines matching that
+address are matched.
+
+@cindex Range of lines
+@cindex Several lines, selecting
+An address range can be specified by specifying two addresses
+separated by a comma (@code{,}).  An address range matches lines
+starting from where the first address matches, and continues
+until the second address matches (inclusively).
+
+If the second address is a @var{regexp}, then checking for the
+ending match will start with the line @emph{following} the
+line which matched the first address: a range will always
+span at least two lines (except of course if the input stream
+ends).
+
+If the second address is a @var{number} less than (or equal to)
+the line matching the first address, then only the one line is
+matched.

+@cindex @acronym{GNU} extensions, @var{addr1},+@var{N} addressing
+@cindex @acronym{GNU} extensions, @var{addr1},~@var{N} addressing
+@value{SSED} also supports some special two-address forms; all these
+are @acronym{GNU} extensions:
+@table @code
+@item 0,/@var{regexp}/
+A line number of @code{0} can be used in an address specification like
+@code{0,/@var{regexp}/} so that @command{sed} will try to match
+@var{regexp} in the first input line too.  In other words,
+@code{0,/@var{regexp}/} is similar to @code{1,/@var{regexp}/},
+except that if @var{addr2} matches the very first line of input the
+@code{0,/@var{regexp}/} form will consider it to end the range, whereas
+the @code{1,/@var{regexp}/} form will match the beginning of its range and
+hence make the range span up to the @emph{second} occurrence of the
+regular expression.
+
+Note that this is the only place where the @code{0} address makes
+sense; there is no 0-th line and commands which are given the @code{0}
+address in any other way will give an error.
+
+@item @var{addr1},+@var{N}
+Matches @var{addr1} and the @var{N} lines following @var{addr1}.
+
+@item @var{addr1},~@var{N}
+Matches @var{addr1} and the lines following @var{addr1}
+until the next line whose input line number is a multiple of @var{N}.
+@end table
+
+@cindex Excluding lines
+@cindex Selecting non-matching lines
+Appending the @code{!} character to the end of an address
+specification negates the sense of the match.
+That is, if the @code{!} character follows an address range,
+then only lines which do @emph{not} match the address range
+will be selected.
+This also works for singleton addresses,
+and, perhaps perversely, for the null address.
+
+
+@node Regular Expressions
+@section Overview of Regular Expression Syntax
+
+To know how to use @command{sed}, people should understand regular
+expressions (@dfn{regexp} for short).  A regular expression
+is a pattern that is matched against a
+subject string from left to right.  Most characters are
+@dfn{ordinary}: they stand for
+themselves in a pattern, and match the corresponding characters
+in the subject.  As a trivial example, the pattern
+
+@example
+The quick brown fox
+@end example
+
+@noindent
+matches a portion of a subject string that is identical to
+itself.  The power of regular expressions comes from the
+ability to include alternatives and repetitions in the pattern.
+These are encoded in the pattern by the use of @dfn{special characters},
+which do not stand for themselves but instead
+are interpreted in some special way.  Here is a brief description
+of regular expression syntax as used in @command{sed}.
+
+@table @code
+@item @var{char}
+A single ordinary character matches itself.
+
+@item *
+@cindex @acronym{GNU} extensions, to basic regular expressions
+Matches a sequence of zero or more instances of matches for the
+preceding regular expression, which must be an ordinary character, a
+special character preceded by @code{\}, a @code{.}, a grouped regexp
+(see below), or a bracket expression.  As a @acronym{GNU} extension, a
+postfixed regular expression can also be followed by @code{*}; for
+example, @code{a**} is equivalent to @code{a*}.  @acronym{POSIX}
+1003.1-2001 says that @code{*} stands for itself when it appears at
+the start of a regular expression or subexpression, but many
+non@acronym{GNU} implementations do not support this and portable
+scripts should instead use @code{\*} in these contexts.
+
+@item \+
+@cindex @acronym{GNU} extensions, to basic regular expressions
+As @code{*}, but matches one or more.  It is a @acronym{GNU} extension.
+
+@item \?
+@cindex @acronym{GNU} extensions, to basic regular expressions
+As @code{*}, but only matches zero or one.  It is a @acronym{GNU} extension.
+
+@item \@{@var{i}\@}
+As @code{*}, but matches exactly @var{i} sequences (@var{i} is a
+decimal integer; for portability, keep it between 0 and 255
+inclusive).
+
+@item \@{@var{i},@var{j}\@}
+Matches between @var{i} and @var{j}, inclusive, sequences.
+
+@item \@{@var{i},\@}
+Matches more than or equal to @var{i} sequences.
+
+@item \(@var{regexp}\)
+Groups the inner @var{regexp} as a whole, this is used to: 
+
+@itemize @bullet
+@item
+@cindex @acronym{GNU} extensions, to basic regular expressions
+Apply postfix operators, like @code{\(abcd\)*}:
+this will search for zero or more whole sequences 
+of @samp{abcd}, while @code{abcd*} would search
+for @samp{abc} followed by zero or more occurrences
+of @samp{d}.  Note that support for @code{\(abcd\)*} is
+required by @acronym{POSIX} 1003.1-2001, but many non-@acronym{GNU}
+implementations do not support it and hence it is not universally
+portable.         
+
+@item
+Use back references (see below).
+@end itemize
+
+@item .
+Matches any character, including newline.
+
+@item ^
+Matches the null string at beginning of the pattern space, i.e. what
+appears after the circumflex must appear at the beginning of the
+pattern space.
+
+In most scripts, pattern space is initialized to the content of each
+line (@pxref{Execution Cycle, , How @code{sed} works}).  So, it is a
+useful simplification to think of @code{^#include} as matching only
+lines where @samp{#include} is the first thing on line---if there are
+spaces before, for example, the match fails.  This simplification is
+valid as long as the original content of pattern space is not modified,
+for example with an @code{s} command.
+
+@code{^} acts as a special character only at the beginning of the
+regular expression or subexpression (that is, after @code{\(} or
+@code{\|}).  Portable scripts should avoid @code{^} at the beginning of
+a subexpression, though, as @acronym{POSIX} allows implementations that
+treat @code{^} as an ordinary character in that context.
+
+@item $
+It is the same as @code{^}, but refers to end of pattern space.
+@code{$} also acts as a special character only at the end
+of the regular expression or subexpression (that is, before @code{\)}
+or @code{\|}), and its use at the end of a subexpression is not
+portable.
+
+
+@item [@var{list}]
+@itemx [^@var{list}]
+Matches any single character in @var{list}: for example,
+@code{[aeiou]} matches all vowels.  A list may include
+sequences like @code{@var{char1}-@var{char2}}, which
+matches any character between (inclusive) @var{char1}
+and @var{char2}.
+
+A leading @code{^} reverses the meaning of @var{list}, so that
+it matches any single character @emph{not} in @var{list}.  To include
+@code{]} in the list, make it the first character (after
+the @code{^} if needed), to include @code{-} in the list,
+make it the first or last; to include @code{^} put
+it after the first character.
+
+@cindex @code{POSIXLY_CORRECT} behavior, bracket expressions
+The characters @code{$}, @code{*}, @code{.}, @code{[}, and @code{\}
+are normally not special within @var{list}.  For example, @code{[\*]}
+matches either @samp{\} or @samp{*}, because the @code{\} is not
+special here.  However, strings like @code{[.ch.]}, @code{[=a=]}, and
+@code{[:space:]} are special within @var{list} and represent collating
+symbols, equivalence classes, and character classes, respectively, and
+@code{[} is therefore special within @var{list} when it is followed by
+@code{.}, @code{=}, or @code{:}.  Also, when not in
+@env{POSIXLY_CORRECT} mode, special escapes like @code{\n} and
+@code{\t} are recognized within @var{list}.  @xref{Escapes}.
+
+@item @var{regexp1}\|@var{regexp2}
+@cindex @acronym{GNU} extensions, to basic regular expressions
+Matches either @var{regexp1} or @var{regexp2}.  Use
+parentheses to use complex alternative regular expressions.
+The matching process tries each alternative in turn, from
+left to right, and the first one that succeeds is used.
+It is a @acronym{GNU} extension.
+
+@item @var{regexp1}@var{regexp2}
+Matches the concatenation of @var{regexp1} and @var{regexp2}.
+Concatenation binds more tightly than @code{\|}, @code{^}, and
+@code{$}, but less tightly than the other regular expression
+operators.
+
+@item \@var{digit}
+Matches the @var{digit}-th @code{\(@dots{}\)} parenthesized
+subexpression in the regular expression.  This is called a @dfn{back
+reference}.  Subexpressions are implicity numbered by counting
+occurrences of @code{\(} left-to-right.
+
+@item \n
+Matches the newline character.
+
+@item \@var{char}
+Matches @var{char}, where @var{char} is one of @code{$},
+@code{*}, @code{.}, @code{[}, @code{\}, or @code{^}.
+Note that the only C-like
+backslash sequences that you can portably assume to be
+interpreted are @code{\n} and @code{\\}; in particular
+@code{\t} is not portable, and matches a @samp{t} under most
+implementations of @command{sed}, rather than a tab character.
+
+@end table
+
+@cindex Greedy regular expression matching
+Note that the regular expression matcher is greedy, i.e., matches
+are attempted from left to right and, if two or more matches are
+possible starting at the same character, it selects the longest.
+
+@noindent
+Examples:
+@table @samp
+@item abcdef
+Matches @samp{abcdef}.
+
+@item a*b
+Matches zero or more @samp{a}s followed by a single
+@samp{b}.  For example, @samp{b} or @samp{aaaaab}. 
+
+@item a\?b
+Matches @samp{b} or @samp{ab}.
+
+@item a\+b\+
+Matches one or more @samp{a}s followed by one or more
+@samp{b}s: @samp{ab} is the shortest possible match, but
+other examples are @samp{aaaab} or @samp{abbbbb} or
+@samp{aaaaaabbbbbbb}.
+
+@item .*
+@itemx .\+
+These two both match all the characters in a string;
+however, the first matches every string (including the empty
+string), while the second matches only strings containing
+at least one character.
+
+@item ^main.*(.*)
+This matches a string starting with @samp{main},
+followed by an opening and closing
+parenthesis.  The @samp{n}, @samp{(} and @samp{)} need not
+be adjacent.
+
+@item ^#
+This matches a string beginning with @samp{#}.
+
+@item \\$
+This matches a string ending with a single backslash.  The
+regexp contains two backslashes for escaping.
+
+@item \$
+Instead, this matches a string consisting of a single dollar sign,
+because it is escaped.
+
+@item [a-zA-Z0-9]
+In the C locale, this matches any @acronym{ASCII} letters or digits.
+
+@item [^ @kbd{tab}]\+
+(Here @kbd{tab} stands for a single tab character.)
+This matches a string of one or more
+characters, none of which is a space or a tab.
+Usually this means a word.
+
+@item ^\(.*\)\n\1$
+This matches a string consisting of two equal substrings separated by
+a newline.
+
+@item .\@{9\@}A$
+This matches nine characters followed by an @samp{A}.
+
+@item ^.\@{15\@}A
+This matches the start of a string that contains 16 characters,
+the last of which is an @samp{A}.

+@end table
+
+@node The "s" Command
+@section The @code{s} Command
+
+The syntax of the @code{s} (as in substitute) command is
+@samp{s/@var{regexp}/@var{replacement}/@var{flags}}.  The @code{/}
+characters may be uniformly replaced by any other single
+character within any given @code{s} command.  The @code{/}
+character (or whatever other character is used in its stead)
+can appear in the @var{regexp} or @var{replacement}
+only if it is preceded by a @code{\} character.
+
+The @code{s} command is probably the most important in @command{sed}
+and has a lot of different options.  Its basic concept is simple:
+the @code{s} command attempts to match the pattern
+space against the supplied @var{regexp}; if the match is
+successful, then that portion of the pattern
+space which was matched is replaced with @var{replacement}.
+
+@cindex Backreferences, in regular expressions
+@cindex Parenthesized substrings
+The @var{replacement} can contain @code{\@var{n}} (@var{n} being
+a number from 1 to 9, inclusive) references, which refer to
+the portion of the match which is contained between the @var{n}th
+@code{\(} and its matching @code{\)}.
+Also, the @var{replacement} can contain unescaped @code{&}
+characters which reference the whole matched portion
+of the pattern space.
+@cindex @value{SSEDEXT}, case modifiers in @code{s} commands
+Finally, as a @value{SSED} extension, you can include a
+special sequence made of a backslash and one of the letters
+@code{L}, @code{l}, @code{U}, @code{u}, or @code{E}.
+The meaning is as follows:
+
+@table @code
+@item \L
+Turn the replacement
+to lowercase until a @code{\U} or @code{\E} is found,
+
+@item \l
+Turn the
+next character to lowercase,
+
+@item \U
+Turn the replacement to uppercase
+until a @code{\L} or @code{\E} is found,
+
+@item \u
+Turn the next character
+to uppercase,
+
+@item \E
+Stop case conversion started by @code{\L} or @code{\U}.
+@end table
+
+When the @code{g} flag is being used, case conversion does not
+propagate from one occurrence of the regular expression to
+another.  For example, when the following command is executed
+with @samp{a-b-} in pattern space:
+@example
+s/\(b\?\)-/x\u\1/g
+@end example
+
+@noindent
+the output is @samp{axxB}.  When replacing the first @samp{-},
+the @samp{\u} sequence only affects the empty replacement of
+@samp{\1}.  It does not affect the @code{x} character that is
+added to pattern space when replacing @code{b-} with @code{xB}.
+
+On the other hand, @code{\l} and @code{\u} do affect the remainder
+of the replacement text if they are followed by an empty substitution.
+With @samp{a-b-} in pattern space, the following command:
+@example
+s/\(b\?\)-/\u\1x/g
+@end example
+
+@noindent
+will replace @samp{-} with @samp{X} (uppercase) and @samp{b-} with
+@samp{Bx}.  If this behavior is undesirable, you can prevent it by
+adding a @samp{\E} sequence---after @samp{\1} in this case.
+
+To include a literal @code{\}, @code{&}, or newline in the final
+replacement, be sure to precede the desired @code{\}, @code{&},
+or newline in the @var{replacement} with a @code{\}.
+
+@findex s command, option flags
+@cindex Substitution of text, options
+The @code{s} command can be followed by zero or more of the
+following @var{flags}:

+@table @code
+@item g
+@cindex Global substitution
+@cindex Replacing all text matching regexp in a line
+Apply the replacement to @emph{all} matches to the @var{regexp},
+not just the first.

+@cindex Replacing only @var{n}th match of regexp in a line
+Only replace the @var{number}th match of the @var{regexp}.
+
+@cindex @acronym{GNU} extensions, @code{g} and @var{number} modifier interaction in @code{s} command
+@cindex Mixing @code{g} and @var{number} modifiers in the @code{s} command
+Note: the @sc{posix} standard does not specify what should happen
+when you mix the @code{g} and @var{number} modifiers,
+and currently there is no widely agreed upon meaning
+across @command{sed} implementations.
+For @value{SSED}, the interaction is defined to be:
+ignore matches before the @var{number}th,
+and then match and replace all matches from
+the @var{number}th on.
+
+@item p
+@cindex Text, printing after substitution
+If the substitution was made, then print the new pattern space.
+
+Note: when both the @code{p} and @code{e} options are specified,
+the relative ordering of the two produces very different results.
+In general, @code{ep} (evaluate then print) is what you want,
+but operating the other way round can be useful for debugging.
+For this reason, the current version of @value{SSED} interprets
+specially the presence of @code{p} options both before and after
+@code{e}, printing the pattern space before and after evaluation,
+while in general flags for the @code{s} command show their
+effect just once.  This behavior, although documented, might
+change in future versions.
+
+@item w @var{file-name}
+@cindex Text, writing to a file after substitution
+@cindex @value{SSEDEXT}, @file{/dev/stdout} file
+@cindex @value{SSEDEXT}, @file{/dev/stderr} file
+If the substitution was made, then write out the result to the named file.
+As a @value{SSED} extension, two special values of @var{file-name} are
+supported: @file{/dev/stderr}, which writes the result to the standard
+error, and @file{/dev/stdout}, which writes to the standard
+output.@footnote{This is equivalent to @code{p} unless the @option{-i}
+option is being used.}
+
+@item e
+@cindex Evaluate Bourne-shell commands, after substitution
+@cindex Subprocesses
+@cindex @value{SSEDEXT}, evaluating Bourne-shell commands
+@cindex @value{SSEDEXT}, subprocesses
+This command allows one to pipe input from a shell command
+into pattern space.  If a substitution was made, the command
+that is found in pattern space is executed and pattern space
+is replaced with its output.  A trailing newline is suppressed;
+results are undefined if the command to be executed contains
+a @sc{nul} character.  This is a @value{SSED} extension.

+@end ifset
+The @code{M} modifier to regular-expression matching is a @value{SSED}
+extension which directs @value{SSED} to match the regular expression
+in @cite{multi-line} mode.  The modifier causes @code{^} and @code{$} to
+match respectively (in addition to the normal behavior) the empty string
+after a newline, and the empty string before a newline.  There are
+special character sequences
+@ifset PERL
+(@code{\A} and @code{\Z} in Perl mode, @code{\`} and @code{\'}
+in basic or extended regular expression modes)
+@end ifset
+@ifclear PERL
+(@code{\`} and @code{\'})

+which always match the beginning or the end of the buffer.
+In addition,

+Queue the lines of text which follow this command
+(each but the last ending with a @code{\},

+
+Escape sequences in @var{text} are processed, so you should
+use @code{\\} in @var{text} to print a single backslash.
+
+As a @acronym{GNU} extension, if between the @code{a} and the newline there is
+other than a whitespace-@code{\} sequence, then the text of this line,
+starting at the first non-whitespace character after the @code{a},
+is taken as the first line of the @var{text} block.
+(This enables a simplification in scripting a one-line add.)

+
+The file will be created (or truncated) before the first input line is

+@node Extended Commands
+@section Commands Specific to @value{SSED}
+
+These commands are specific to @value{SSED}, so you
+must use them with care and only when you are sure that
+hindering portability is not evil.  They allow you to check
+for @value{SSED} extensions or to do tasks that are required
+quite often, yet are unsupported by standard @command{sed}s.
+
+@table @code
+@item e [@var{command}]
+@findex e (evaluate) command
+@cindex Evaluate Bourne-shell commands
+@cindex Subprocesses
+@cindex @value{SSEDEXT}, evaluating Bourne-shell commands
+@cindex @value{SSEDEXT}, subprocesses
+This command allows one to pipe input from a shell command
+into pattern space.  Without parameters, the @code{e} command
+executes the command that is found in pattern space and
+replaces the pattern space with the output; a trailing newline
+is suppressed.
+
+If a parameter is specified, instead, the @code{e} command
+interprets it as a command and sends its output to the output stream.
+The command can run across multiple lines, all but the last ending with
+a back-slash.
+
+In both cases, the results are undefined if the command to be
+executed contains a @sc{nul} character.
+
+Note that, unlike the @code{r} command, the output of the command will
+be printed immediately; the @code{r} command instead delays the output
+to the end of the current cycle.
+
+@item F
+@findex F (File name) command
+@cindex Printing file name
+@cindex File name, printing
+Print out the file name of the current input file (with a trailing
+newline).
+
+@item L @var{n}

+@cindex Reformat pattern space
+@cindex Reformatting paragraphs
+@cindex @value{SSEDEXT}, reformatting paragraphs
+@cindex @value{SSEDEXT}, @code{L} command
+This @value{SSED} extension fills and joins lines in pattern space
+to produce output lines of (at most) @var{n} characters, like
+@code{fmt} does; if @var{n} is omitted, the default as specified
+on the command line is used.  This command is considered a failed
+experiment and unless there is enough request (which seems unlikely)
+will be removed in future versions.
+
+@ignore
+Blank lines, spaces between words, and indentation are
+preserved in the output; successive input lines with different
+indentation are not joined; tabs are expanded to 8 columns.
+
+If the pattern space contains multiple lines, they are joined, but
+since the pattern space usually contains a single line, the behavior
+of a simple @code{L;d} script is the same as @samp{fmt -s} (i.e.,
+it does not join short lines to form longer ones).
+
+@var{n} specifies the desired line-wrap length; if omitted,
+the default as specified on the command line is used.
+@end ignore

+
+@findex Q (silent Quit) command
+@cindex @value{SSEDEXT}, quitting silently
+@cindex @value{SSEDEXT}, returning an exit code
+@cindex Quitting
+This command is the same as @code{q}, but will not print the
+contents of pattern space.  Like @code{q}, it provides the
+ability to return an exit code to the caller.
+
+This command can be useful because the only alternative ways
+to accomplish this apparently trivial function are to use
+the @option{-n} option (which can unnecessarily complicate
+your script) or resorting to the following snippet, which
+wastes time by reading the whole file without any visible effect:
+
+@example
+:eat
+$d       @i{@r{Quit silently on the last line}}
+N        @i{@r{Read another line, silently}}
+g        @i{@r{Overwrite pattern space each time to save memory}}
+b eat
+@end example
+
+@item R @var{filename}
+@findex R (read line) command
+@cindex Read text from a file
+@cindex @value{SSEDEXT}, reading a file a line at a time
+@cindex @value{SSEDEXT}, @code{R} command
+@cindex @value{SSEDEXT}, @file{/dev/stdin} file
+Queue a line of @var{filename} to be read and
+inserted into the output stream at the end of the current cycle,
+or when the next input line is read.
+Note that if @var{filename} cannot be read, or if its end is
+reached, no line is appended, without any error indication.
+
+As with the @code{r} command, the special value @file{/dev/stdin}
+is supported for the file name, which reads a line from the
+standard input.
+
+@item T @var{label}
+@findex T (test and branch if failed) command
+@cindex @value{SSEDEXT}, branch if @code{s///} failed
+@cindex Branch to a label, if @code{s///} failed
+@cindex Conditional branch
+Branch to @var{label} only if there have been no successful
+@code{s}ubstitutions since the last input line was read or
+conditional branch was taken. The @var{label} may be omitted,
+in which case the next cycle is started.
+
+@item v @var{version}
+@findex v (version) command
+@cindex @value{SSEDEXT}, checking for their presence
+@cindex Requiring @value{SSED}
+This command does nothing, but makes @command{sed} fail if
+@value{SSED} extensions are not supported, simply because other
+versions of @command{sed} do not implement it.  In addition, you
+can specify the version of @command{sed} that your script
+requires, such as @code{4.0.5}.  The default is @code{4.0}
+because that is the first version that implemented this command.
+
+This command enables all @value{SSEDEXT} even if
+@env{POSIXLY_CORRECT} is set in the environment.
+
+@item W @var{filename}
+@findex W (write first line) command
+@cindex Write first line to a file
+@cindex @value{SSEDEXT}, writing first line to a file
+Write to the given filename the portion of the pattern space up to
+the first newline.  Everything said under the @code{w} command about
+file handling holds here too.
+
+@item z
+@findex z (Zap) command
+@cindex @value{SSEDEXT}, emptying pattern space
+@cindex Emptying pattern space
+This command empties the content of pattern space.  It is
+usually the same as @samp{s/.*//}, but is more efficient
+and works in the presence of invalid multibyte sequences
+in the input stream.  @sc{posix} mandates that such sequences
+are @emph{not} matched by @samp{.}, so that there is no portable
+way to clear @command{sed}'s buffers in the middle of the
+script in most multibyte locales (including UTF-8 locales).

+@node Escapes
+@section @acronym{GNU} Extensions for Escapes in Regular Expressions
+
+@cindex @acronym{GNU} extensions, special escapes
+Until this chapter, we have only encountered escapes of the form
+@samp{\^}, which tell @command{sed} not to interpret the circumflex
+as a special character, but rather to take it literally.  For
+example, @samp{\*} matches a single asterisk rather than zero
+or more backslashes.
+
+@cindex @code{POSIXLY_CORRECT} behavior, escapes
+This chapter introduces another kind of escape@footnote{All
+the escapes introduced here are @acronym{GNU}
+extensions, with the exception of @code{\n}.  In basic regular
+expression mode, setting @code{POSIXLY_CORRECT} disables them inside
+bracket expressions.}---that
+is, escapes that are applied to a character or sequence of characters
+that ordinarily are taken literally, and that @command{sed} replaces
+with a special character.  This provides a way
+of encoding non-printable characters in patterns in a visible manner.
+There is no restriction on the appearance of non-printing characters
+in a @command{sed} script but when a script is being prepared in the
+shell or by text editing, it is usually easier to use one of
+the following escape sequences than the binary character it
+represents:
+
+The list of these escapes is:
+
+@table @code
+@item \a
+Produces or matches a @sc{bel} character, that is an ``alert'' (@sc{ascii} 7).
+
+@item \f
+Produces or matches a form feed (@sc{ascii} 12).
+
+@item \n
+Produces or matches a newline (@sc{ascii} 10).
+
+@item \r
+Produces or matches a carriage return (@sc{ascii} 13).
+
+@item \t
+Produces or matches a horizontal tab (@sc{ascii} 9).
+
+@item \v
+Produces or matches a so called ``vertical tab'' (@sc{ascii} 11).
+
+@item \c@var{x}
+Produces or matches @kbd{@sc{Control}-@var{x}}, where @var{x} is
+any character.  The precise effect of @samp{\c@var{x}} is as follows:
+if @var{x} is a lower case letter, it is converted to upper case.
+Then bit 6 of the character (hex 40) is inverted.  Thus @samp{\cz} becomes
+hex 1A, but @samp{\c@{} becomes hex 3B, while @samp{\c;} becomes hex 7B.
+
+@item \d@var{xxx}
+Produces or matches a character whose decimal @sc{ascii} value is @var{xxx}.
+
+@item \o@var{xxx}
+@ifset PERL
+@item \@var{xxx}
+@end ifset
+Produces or matches a character whose octal @sc{ascii} value is @var{xxx}.
+@ifset PERL
+The syntax without the @code{o} is active in Perl mode, while the one
+with the @code{o} is active in the normal or extended @sc{posix} regular
+expression modes.
+@end ifset
+
+@item \x@var{xx}
+Produces or matches a character whose hexadecimal @sc{ascii} value is @var{xx}.
+@end table
+
+@samp{\b} (backspace) was omitted because of the conflict with
+the existing ``word boundary'' meaning.
+
+Other escapes match a particular character class and are valid only in
+regular expressions:
+
+@table @code
+@item \w
+Matches any ``word'' character.  A ``word'' character is any
+letter or digit or the underscore character.
+
+@item \W
+Matches any ``non-word'' character.
+
+@item \b
+Matches a word boundary; that is it matches if the character
+to the left is a ``word'' character and the character to the
+right is a ``non-word'' character, or vice-versa.
+
+@item \B
+Matches everywhere but on a word boundary; that is it matches
+if the character to the left and the character to the right
+are either both ``word'' characters or both ``non-word''
+characters.
+
+@item \`
+Matches only at the start of pattern space.  This is different
+from @code{^} in multi-line mode.
+
+@item \'
+Matches only at the end of pattern space.  This is different
+from @code{$} in multi-line mode.
+
+@ifset PERL
+@item \G
+Match only at the start of pattern space or, when doing a global
+substitution using the @code{s///g} command and option, at
+the end-of-match position of the prior match.  For example,
+@samp{s/\Ga/Z/g} will change an initial run of @code{a}s to
+a run of @code{Z}s

+@node Centering lines
+@section Centering Lines
+
+This script centers all lines of a file on a 80 columns width.
+To change that width, the number in @code{\@{@dots{}\@}} must be
+replaced, and the number of added spaces also must be changed.
+
+Note how the buffer commands are used to separate parts in
+the regular expressions to be matched---this is a common
+technique.
+
+@c start-------------------------------------------
+@example
+#!/usr/bin/sed -f
+
+# Put 80 spaces in the buffer
+1 @{
+  x
+  s/^$/          /
+  s/^.*$/&&&&&&&&/
+  x
+@}
+
+# del leading and trailing spaces
+y/@kbd{tab}/ /
+s/^ *//
+s/ *$//
+
+# add a newline and 80 spaces to end of line
+G
+
+# keep first 81 chars (80 + a newline)
+s/^\(.\@{81\@}\).*$/\1/
+
+# \2 matches half of the spaces, which are moved to the beginning
+s/^\(.*\)\n\(.*\)\2/\2\1/
+@end example
+@c end---------------------------------------------
+
+@node Increment a number
+@section Increment a Number
+
+This script is one of a few that demonstrate how to do arithmetic
+in @command{sed}.  This is indeed possible,@footnote{@command{sed} guru Greg
+Ubben wrote an implementation of the @command{dc} @sc{rpn} calculator!
+It is distributed together with sed.} but must be done manually.
+
+To increment one number you just add 1 to last digit, replacing
+it by the following digit.  There is one exception: when the digit
+is a nine the previous digits must be also incremented until you
+don't have a nine.
+
+This solution by Bruno Haible is very clever and smart because
+it uses a single buffer; if you don't have this limitation, the
+algorithm used in @ref{cat -n, Numbering lines}, is faster.
+It works by replacing trailing nines with an underscore, then
+using multiple @code{s} commands to increment the last digit,
+and then again substituting underscores with zeros.
+
+@c start-------------------------------------------
+@example
+#!/usr/bin/sed -f
+
+/[^0-9]/ d
+
+# replace all trailing 9s by _ (any other character except digits, could
+# be used)
+:d
+s/9\(_*\)$/_\1/
+td
+
+# incr last digit only.  The first line adds a most-significant
+# digit of 1 if we have to add a digit.

+@node Rename files to lower case
+@section Rename Files to Lower Case
+
+This is a pretty strange use of @command{sed}.  We transform text, and
+transform it to be shell commands, then just feed them to shell.
+Don't worry, even worse hacks are done when using @command{sed}; I have
+seen a script converting the output of @command{date} into a @command{bc}
+program!
+
+The main body of this is the @command{sed} script, which remaps the name
+from lower to upper (or vice-versa) and even checks out 
+if the remapped name is the same as the original name.
+Note how the script is parameterized using shell
+variables and proper quoting.

+
+@node Reverse chars of lines
+@section Reverse Characters of Lines
+
+This script can be used to reverse the position of characters
+in lines.  The technique moves two characters at a time, hence
+it is faster than more intuitive implementations.
+
+Note the @code{tx} command before the definition of the label.
+This is often needed to reset the flag that is tested by
+the @code{t} command.
+
+Imaginative readers will find uses for this script.  An example
+is reversing the output of @command{banner}.@footnote{This requires
+another script to pad the output of banner; for example
+
+@example
+#! /bin/sh
+
+banner -w $1 $2 $3 $4 |
+  sed -e :a -e '/^.\@{0,'$1'\@}$/ @{ s/$/ /; ba; @}' |

+
+@node tac
+@section Reverse Lines of Files
+
+This one begins a series of totally useless (yet interesting)
+scripts emulating various Unix commands.  This, in particular,
+is a @command{tac} workalike.
+
+Note that on implementations other than @acronym{GNU} @command{sed}
+@ifset PERL
+and @value{SSED}
+@end ifset
+this script might easily overflow internal buffers.
+
+@c start-------------------------------------------
+@example
+#!/usr/bin/sed -nf
+
+# reverse all lines of input, i.e. first line became last, ...
+
+# from the second line, the buffer (which contains all previous lines)
+# is *appended* to current line, so, the order will be reversed
+1! G
+
+# on the last line we're done -- print everything
+$ p
+
+# store everything on the buffer again
+h
+@end example
+@c end---------------------------------------------
+
+@node cat -n
+@section Numbering Lines
+
+This script replaces @samp{cat -n}; in fact it formats its output
+exactly like @acronym{GNU} @command{cat} does.
+
+Of course this is completely useless and for two reasons:  first,
+because somebody else did it in C, second, because the following
+Bourne-shell script could be used for the same purpose and would
+be much faster:
+
+@c start-------------------------------------------
+@example
+#! /bin/sh
+sed -e "=" $@@ | sed -e '
+  s/^/      /
+  N
+  s/^ *\(......\)\n/\1  /
+'
+@end example
+@c end---------------------------------------------
+
+It uses @command{sed} to print the line number, then groups lines two
+by two using @code{N}.  Of course, this script does not teach as much as
+the one presented below.
+
+The algorithm used for incrementing uses both buffers, so the line
+is printed as soon as possible and then discarded.  The number
+is split so that changing digits go in a buffer and unchanged ones go
+in the other; the changed digits are modified in a single step
+(using a @code{y} command).  The line number for the next line
+is then composed and stored in the hold space, to be used in the
+next iteration.
+
+@c start-------------------------------------------
+@example
+#!/usr/bin/sed -nf
+
+# Prime the pump on the first line
+x
+/^$/ s/^.*$/1/
+
+# Add the correct line number before the pattern
+G
+h
+
+# Format it and print it
+s/^/      /
+s/^ *\(......\)\n/\1  /p
+
+# Get the line number from hold space; add a zero
+# if we're going to add a digit on the next line
+g
+s/\n.*$//
+/^9*$/ s/^/0/
+
+# separate changing/unchanged digits with an x

+x
+
+# keep unchanged digits in pattern space
+s/x.*$//

+# compose the new number, remove the newline implicitly added by G

+@end example
+@c end---------------------------------------------

+@node wc -c
+@section Counting Characters
+
+This script shows another way to do arithmetic with @command{sed}.
+In this case we have to add possibly large numbers, so implementing
+this by successive increments would not be feasible (and possibly
+even more complicated to contrive than this script).
+
+The approach is to map numbers to letters, kind of an abacus
+implemented with @command{sed}.  @samp{a}s are units, @samp{b}s are
+tens and so on: we simply add the number of characters
+on the current line as units, and then propagate the carry
+to tens, hundreds, and so on.
+
+As usual, running totals are kept in hold space.
+
+On the last line, we convert the abacus form back to decimal.
+For the sake of variety, this is done with a loop rather than
+with some 80 @code{s} commands@footnote{Some implementations
+have a limit of 199 commands per script}: first we
+convert units, removing @samp{a}s from the number; then we
+rotate letters so that tens become @samp{a}s, and so on
+until no more letters remain.
+
+@c start-------------------------------------------
+@example
+#!/usr/bin/sed -nf
+
+# Add n+1 a's to hold space (+1 is for the newline)
+s/./a/g
+H
+x
+s/\n/a/

+@node wc -w
+@section Counting Words
+
+This script is almost the same as the previous one, once each
+of the words on the line is converted to a single @samp{a}
+(in the previous script each letter was changed to an @samp{a}).
+
+It is interesting that real @command{wc} programs have optimized
+loops for @samp{wc -c}, so they are much slower at counting
+words rather than characters.  This script's bottleneck,
+instead, is arithmetic, and hence the word-counting one
+is faster (it has to manage smaller numbers).
+
+Again, the common parts are not commented to show the importance
+of commenting @command{sed} scripts.

+@section Counting Lines
+
+No strange things are done now, because @command{sed} gives us

+@example
+#!/usr/bin/sed -nf
+$=
+@end example
+@c end---------------------------------------------
+
+@node head
+@section Printing the First Lines
+
+This script is probably the simplest useful @command{sed} script.
+It displays the first 10 lines of input; the number of displayed
+lines is right before the @code{q} command.
+
+@c start-------------------------------------------
+@example
+#!/usr/bin/sed -f
+10q
+@end example
+@c end---------------------------------------------
+
+@node tail
+@section Printing the Last Lines
+
+Printing the last @var{n} lines rather than the first is more complex
+but indeed possible.  @var{n} is encoded in the second line, before
+the bang character.
+
+This script is similar to the @command{tac} script in that it keeps the
+final output in the hold space and prints it at the end:
+
+@c start-------------------------------------------
+@example
+#!/usr/bin/sed -nf
+
+1! @{; H; g; @}
+1,10 !s/[^\n]*\n//
+$p
+h
+@end example
+@c end---------------------------------------------
+
+Mainly, the scripts keeps a window of 10 lines and slides it
+by adding a line and deleting the oldest (the substitution command
+on the second line works like a @code{D} command but does not
+restart the loop).
+
+The ``sliding window'' technique is a very powerful way to write
+efficient and complex @command{sed} scripts, because commands like
+@code{P} would require a lot of work if implemented manually.
+
+To introduce the technique, which is fully demonstrated in the
+rest of this chapter and is based on the @code{N}, @code{P}
+and @code{D} commands, here is an implementation of @command{tail}
+using a simple ``sliding window.''
+
+This looks complicated but in fact the working is the same as
+the last script: after we have kicked in the appropriate number
+of lines, however, we stop using the hold space to keep inter-line
+state, and instead use @code{N} and @code{D} to slide pattern
+space by one line:
+
+@c start-------------------------------------------
+@example
+#!/usr/bin/sed -f
+
+1h
+2,10 @{; H; g; @}
+$q
+1,9d
+N
+D
+@end example
+@c end---------------------------------------------
+
+Note how the first, second and fourth line are inactive after
+the first ten lines of input.  After that, all the script does
+is: exiting on the last line of input, appending the next input
+line to pattern space, and removing the first line.

+This is an example of the art of using the @code{N}, @code{P}
+and @code{D} commands, probably the most difficult to master.
+
+@c start-------------------------------------------
+@example
+#!/usr/bin/sed -f
+h
+
+:b
+# On the last line, print and exit
+$b
+N
+/^\(.*\)\n\1$/ @{
+    # The two lines are identical.  Undo the effect of
+    # the n command.
+    g
+    bb
+@}
+
+# If the @code{N} command had added the last line, print and exit
+$b
+
+# The lines are different; print the first and go
+# back working on the second.
+P
+D
+@end example
+@c end---------------------------------------------
+
+As you can see, we mantain a 2-line window using @code{P} and @code{D}.
+This technique is often used in advanced @command{sed} scripts.
+
+@node uniq -d
+@section Print Duplicated Lines of Input
+
+This script prints only duplicated lines, like @samp{uniq -d}.
+
+@c start-------------------------------------------
+@example
+#!/usr/bin/sed -nf
+
+$b
+N
+/^\(.*\)\n\1$/ @{
+    # Print the first of the duplicated lines
+    s/.*\n//
+    p
+
+    # Loop until we get a different line
+    :b
+    $b
+    N
+    /^\(.*\)\n\1$/ @{
+        s/.*\n//
+        bb
+    @}
+@}
+
+# The last line cannot be followed by duplicates
+$b
+
+# Found a different one.  Leave it alone in the pattern space
+# and go back to the top, hunting its duplicates
+D
+@end example
+@c end---------------------------------------------
+
+@node uniq -u
+@section Remove All Duplicated Lines
+
+This script prints only unique lines, like @samp{uniq -u}.
+
+@c start-------------------------------------------
+@example
+#!/usr/bin/sed -f
+
+# Search for a duplicate line --- until that, print what you find.
+$b
+N
+/^\(.*\)\n\1$/ ! @{
+    P
+    D
+@}
+
+:c
+# Got two equal lines in pattern space.  At the
+# end of the file we simply exit
+$d
+
+# Else, we keep reading lines with @code{N} until we
+# find a different one
+s/.*\n//
+N
+/^\(.*\)\n\1$/ @{
+    bc
+@}
+
+# Remove the last instance of the duplicate line
+# and go back to the top
+D
+@end example
+@c end---------------------------------------------
+
+@node cat -s
+@section Squeezing Blank Lines
+
+As a final example, here are three scripts, of increasing complexity
+and speed, that implement the same function as @samp{cat -s}, that is
+squeezing blank lines.
+
+The first leaves a blank line at the beginning and end if there are
+some already.
+
+@c start-------------------------------------------
+@example
+#!/usr/bin/sed -f
+
+# on empty lines, join with next
+# Note there is a star in the regexp
+:x
+/^\n*$/ @{
+N
+bx
+@}
+
+# now, squeeze all '\n', this can be also done by:
+# s/^\(\n\)*/\1/
+s/\n*/\
+/
+@end example
+@c end---------------------------------------------
+
+This one is a bit more complex and removes all empty lines
+at the beginning.  It does leave a single blank line at end
+if one was there.
+
+@c start-------------------------------------------
+@example
+#!/usr/bin/sed -f
+
+# delete all leading empty lines
+1,/^./@{
+/./!d
+@}
+
+# on an empty line we remove it and all the following
+# empty lines, but one
+:x
+/./!@{
+N
+s/^\n$//
+tx
+@}
+@end example
+@c end---------------------------------------------
+
+This removes leading and trailing blank lines.  It is also the
+fastest.  Note that loops are completely done with @code{n} and
+@code{b}, without relying on @command{sed} to restart the
+the script automatically at the end of a line.
+
+@c start-------------------------------------------
+@example
+#!/usr/bin/sed -nf
+
+# delete all (leading) blanks
+/./!d
+
+# get here: so there is a non empty
+:x
+# print it
+p
+# get next
+n
+# got chars? print it again, etc... 
+/./bx
+
+# no, don't have chars: got an empty line
+:z
+# get next, if last line we finish here so no trailing
+# empty lines are written
+n
+# also empty? then ignore it, and get next... this will
+# remove ALL empty lines
+/./!bz
+
+# all empty lines were deleted/ignored, but we have a non empty.  As
+# what we want to do is to squeeze, insert a blank line artificially
+i\
+
+bx
+@end example

+@node Limitations
+@chapter @value{SSED}'s Limitations and Non-limitations
+
+@cindex @acronym{GNU} extensions, unlimited line length
+@cindex Portability, line length limitations
+For those who want to write portable @command{sed} scripts,
+be aware that some implementations have been known to
+limit line lengths (for the pattern and hold spaces)
+to be no more than 4000 bytes.
+The @sc{posix} standard specifies that conforming @command{sed}
+implementations shall support at least 8192 byte line lengths.
+@value{SSED} has no built-in limit on line length;
+as long as it can @code{malloc()} more (virtual) memory,
+you can feed or construct lines as long as you like.
+
+However, recursion is used to handle subpatterns and indefinite
+repetition.  This means that the available stack space may limit
+the size of the buffer that can be processed by certain patterns.
+
+@ifset PERL
+There are some size limitations in the regular expression
+matcher but it is hoped that they will never in practice
+be relevant.  The maximum length of a compiled pattern
+is 65539 (sic) bytes.  All values in repeating quantifiers
+must be less than 65536.  The maximum nesting depth of
+all parenthesized subpatterns, including capturing and
+non-capturing subpatterns@footnote{The
+distinction is meaningful when referring to Perl-style
+regular expressions.}, assertions, and other types of
+subpattern, is 200.
+
+Also, @value{SSED} recognizes the @sc{posix} syntax
+@code{[.@var{ch}.]} and @code{[=@var{ch}=]}
+where @var{ch} is a ``collating element'', but these
+are not supported, and an error is given if they are
+encountered.
+
+Here are a few distinctions between the real Perl-style
+regular expressions and those that @option{-R} recognizes.
+
+@enumerate
+@item
+Lookahead assertions do not allow repeat quantifiers after them
+Perl permits them, but they do not mean what you
+might think. For example, @samp{(?!a)@{3@}} does not assert that the
+next three characters are not @samp{a}. It just asserts three times that the
+next character is not @samp{a} --- a waste of time and nothing else.
+
+@item
+Capturing subpatterns that occur inside  negative  lookahead
+head  assertions  are  counted,  but  their  entries are counted
+as empty in the second half of an @code{s} command.
+Perl sets its numerical variables from any such patterns
+that are matched before the assertion fails to match
+something (thereby succeeding), but only if the negative
+lookahead assertion contains just one branch.
+
+@item
+The following Perl escape sequences are not supported:
+@samp{\l}, @samp{\u}, @samp{\L}, @samp{\U}, @samp{\E},
+@samp{\Q}. In fact these are implemented by Perl's general
+string-handling and are not part of its pattern matching engine.
+
+@item
+The Perl @samp{\G} assertion is not supported as it is not
+relevant to single pattern matches.
+
+@item
+Fairly obviously, @value{SSED} does not support the @samp{(?@{code@})}
+and @samp{(?p@{code@})} constructions. However, there is some experimental
+support for recursive patterns using the non-Perl item @samp{(?R)}.
+
+@item
+There are at the time of writing some oddities in Perl
+5.005_02 concerned with the settings of captured strings
+when part of a pattern is repeated. For example, matching
+@samp{aba} against the pattern @samp{/^(a(b)?)+$/} sets
+@samp{$2}@footnote{@samp{$2} would be @samp{\2} in @value{SSED}.}
+to the value @samp{b}, but matching @samp{aabbaa}
+against @samp{/^(aa(bb)?)+$/} leaves @samp{$2}
+unset.  However, if the pattern is changed to
+@samp{/^(aa(b(b))?)+$/} then @samp{$2} (and @samp{$3}) are set.
+In Perl 5.004 @samp{$2} is set in both cases, and that is also
+true of @value{SSED}.
+
+@item
+Another as yet unresolved discrepancy is that in Perl
+5.005_02 the pattern @samp{/^(a)?(?(1)a|b)+$/} matches
+the string @samp{a}, whereas in @value{SSED} it does not.
+However, in both Perl and @value{SSED} @samp{/^(a)?a/} matched
+against @samp{a} leaves $1 unset.

+of your report if at all possible.
+
+Please do not send a bug report like this:
+
+@example
+@i{@i{@r{while building frobme-1.3.4}}}
+$ configure 
+@error{} sed: file sedscr line 1: Unknown option to 's'
+@end example
+
+If @value{SSED} doesn't configure your favorite package, take a
+few extra minutes to identify the specific problem and make a stand-alone
+test case.  Unlike other programs such as C compilers, making such test
+cases for @command{sed} is quite simple.
+
+A stand-alone test case includes all the data necessary to perform the
+test, and the specific invocation of @command{sed} that causes the problem.
+The smaller a stand-alone test case is, the better.  A test case should
+not involve something as far removed from @command{sed} as ``try to configure
+frobme-1.3.4''.  Yes, that is in principle enough information to look
+for the bug, but that is not a very practical prospect.
+
+Here are a few commonly reported bugs that are not bugs.
+
+@table @asis
+@item @code{N} command on the last line
+@cindex Portability, @code{N} command on the last line
+@cindex Non-bugs, @code{N} command on the last line
+
+Most versions of @command{sed} exit without printing anything when
+the @command{N} command is issued on the last line of a file.
+@value{SSED} prints pattern space before exiting unless of course
+the @command{-n} command switch has been specified.  This choice is
+by design.
+
+For example, the behavior of
+@example
+sed N foo bar
+@end example
+@noindent
+would depend on whether foo has an even or an odd number of
+lines@footnote{which is the actual ``bug'' that prompted the
+change in behavior}.  Or, when writing a script to read the
+next few lines following a pattern match, traditional
+implementations of @code{sed} would force you to write
+something like
+@example
+/foo/@{ $!N; $!N; $!N; $!N; $!N; $!N; $!N; $!N; $!N @}
+@end example
+@noindent
+instead of just
+@example
+/foo/@{ N;N;N;N;N;N;N;N;N; @}
+@end example
+
+@cindex @code{POSIXLY_CORRECT} behavior, @code{N} command
+In any case, the simplest workaround is to use @code{$d;N} in
+scripts that rely on the traditional behavior, or to set
+the @code{POSIXLY_CORRECT} variable to a non-empty value.
+
+@item Regex syntax clashes (problems with backslashes)
+@cindex @acronym{GNU} extensions, to basic regular expressions
+@cindex Non-bugs, regex syntax clashes
+@command{sed} uses the @sc{posix} basic regular expression syntax.  According to
+the standard, the meaning of some escape sequences is undefined in
+this syntax;  notable in the case of @command{sed} are @code{\|},
+@code{\+}, @code{\?}, @code{\`}, @code{\'}, @code{\<},
+@code{\>}, @code{\b}, @code{\B}, @code{\w}, and @code{\W}.
+
+As in all @acronym{GNU} programs that use @sc{posix} basic regular
+expressions, @command{sed} interprets these escape sequences as special
+characters.  So, @code{x\+} matches one or more occurrences of @samp{x}.
+@code{abc\|def} matches either @samp{abc} or @samp{def}.
+
+This syntax may cause problems when running scripts written for other
+@command{sed}s.  Some @command{sed} programs have been written with the
+assumption that @code{\|} and @code{\+} match the literal characters
+@code{|} and @code{+}.  Such scripts must be modified by removing the
+spurious backslashes if they are to be used with modern implementations
+of @command{sed}, like
+@ifset PERL
+@value{SSED} or
+@end ifset
+@acronym{GNU} @command{sed}.
+
+On the other hand, some scripts use s|abc\|def||g to remove occurrences
+of @emph{either} @code{abc} or @code{def}.  While this worked until
+@command{sed} 4.0.x, newer versions interpret this as removing the
+string @code{abc|def}.  This is again undefined behavior according to
+@acronym{POSIX}, and this interpretation is arguably more robust: older
+@command{sed}s, for example, required that the regex matcher parsed
+@code{\/} as @code{/} in the common case of escaping a slash, which is
+again undefined behavior; the new behavior avoids this, and this is good
+because the regex matcher is only partially under our control.
+
+@cindex @acronym{GNU} extensions, special escapes
+In addition, this version of @command{sed} supports several escape characters
+(some of which are multi-character) to insert non-printable characters
+in scripts (@code{\a}, @code{\c}, @code{\d}, @code{\o}, @code{\r},
+@code{\t}, @code{\v}, @code{\x}).  These can cause similar problems
+with scripts written for other @command{sed}s.
+
+@item @option{-i} clobbers read-only files
+@cindex In-place editing
+@cindex @value{SSEDEXT}, in-place editing
+@cindex Non-bugs, in-place editing
+
+In short, @samp{sed -i} will let you delete the contents of
+a read-only file, and in general the @option{-i} option
+(@pxref{Invoking sed, , Invocation}) lets you clobber
+protected files.  This is not a bug, but rather a consequence
+of how the Unix filesystem works.
+
+The permissions on a file say what can happen to the data
+in that file, while the permissions on a directory say what can
+happen to the list of files in that directory.  @samp{sed -i}
+will not ever open for writing  a file that is already on disk.
+Rather, it will work on a temporary file that is finally renamed
+to the original name: if you rename or delete files, you're actually
+modifying the contents of the directory, so the operation depends on
+the permissions of the directory, not of the file.  For this same
+reason, @command{sed} does not let you use @option{-i} on a writeable file
+in a read-only directory, and will break hard or symbolic links when
+@option{-i} is used on such a file.
+
+@item @code{0a} does not work (gives an error)
+@cindex @code{0} address
+@cindex @acronym{GNU} extensions, @code{0} address
+@cindex Non-bugs, @code{0} address
+
+There is no line 0.  0 is a special address that is only used to treat
+addresses like @code{0,/@var{RE}/} as active when the script starts: if
+you write @code{1,/abc/d} and the first line includes the word @samp{abc},
+then that match would be ignored because address ranges must span at least
+two lines (barring the end of the file); but what you probably wanted is
+to delete every line up to the first one including @samp{abc}, and this
+is obtained with @code{0,/abc/d}.
+
+@ifclear PERL
+@item @code{[a-z]} is case insensitive
+@cindex Non-bugs, localization-related
+
+You are encountering problems with locales.  POSIX mandates that @code{[a-z]}
+uses the current locale's collation order -- in C parlance, that means using
+@code{strcoll(3)} instead of @code{strcmp(3)}.  Some locales have a
+case-insensitive collation order, others don't.
+
+Another problem is that @code{[a-z]} tries to use collation symbols.
+This only happens if you are on the @acronym{GNU} system, using
+@acronym{GNU} libc's regular expression matcher instead of compiling the
+one supplied with @acronym{GNU} sed.  In a Danish locale, for example,
+the regular expression @code{^[a-z]$} matches the string @samp{aa},
+because this is a single collating symbol that comes after @samp{a}
+and before @samp{b}; @samp{ll} behaves similarly in Spanish
+locales, or @samp{ij} in Dutch locales.
+
+To work around these problems, which may cause bugs in shell scripts, set
+the @env{LC_COLLATE} and @env{LC_CTYPE} environment variables to @samp{C}.
+
+@item @code{s/.*//} does not clear pattern space
+@cindex Non-bugs, localization-related
+@cindex @value{SSEDEXT}, emptying pattern space
+@cindex Emptying pattern space
+
+This happens if your input stream includes invalid multibyte
+sequences.  @sc{posix} mandates that such sequences
+are @emph{not} matched by @samp{.}, so that @samp{s/.*//} will not clear
+pattern space as you would expect.  In fact, there is no way to clear
+sed's buffers in the middle of the script in most multibyte locales
+(including UTF-8 locales).  For this reason, @value{SSED} provides a `z'
+command (for `zap') as an extension.
+
+To work around these problems, which may cause bugs in shell scripts, set
+the @env{LC_COLLATE} and @env{LC_CTYPE} environment variables to @samp{C}.

+
+The only difference between basic and extended regular expressions is in
+the behavior of a few characters: @samp{?}, @samp{+}, parentheses,
+braces (@samp{@{@}}), and @samp{|}.  While basic regular expressions
+require these to be escaped if you want them to behave as special
+characters, when using extended regular expressions you must escape
+them if you want them @emph{to match a literal character}.  @samp{|}
+is special here because @samp{\|} is a GNU extension -- standard
+basic regular expressions do not provide its functionality.
+
+@noindent
+Examples:
+@table @code
+@item abc?

+@item c\+
+becomes @samp{c+} when using extended regular expressions.  It matches

+@node Backslash
+@appendixsec Backslash
+@cindex Perl-style regular expressions, escaped sequences
+
+There are a few difference in the handling of backslashed 
+sequences in Perl mode.
+
+First of all, there are no @code{\o} and @code{\d} sequences.
+@sc{ascii} values for characters can be specified in octal
+with a @code{\@var{xxx}} sequence, where @var{xxx} is a
+sequence of up to three octal digits.  If the first digit
+is a zero, the treatment of the sequence is straightforward;
+just note that if the character that follows the escaped digit
+is itself an octal digit, you have to supply three octal digits
+for @var{xxx}.  For example @code{\07} is a @sc{bel} character
+rather than a @sc{nul} and a literal @code{7} (this sequence is
+instead represented by @code{\0007}).
+
+@cindex Perl-style regular expressions, backreferences
+The handling of a backslash followed by a digit other than 0
+is complicated.  Outside a character class, @command{sed} reads it
+and any following digits as a decimal number. If the number
+is less than 10, or if there have been at least that many
+previous capturing left parentheses in the expression, the
+entire sequence is taken as a back reference. A description
+of how this works is given later, following the discussion
+of parenthesized subpatterns.
+
+Inside a character class, or if the decimal number is
+greater than 9 and there have not been that many capturing
+subpatterns, @command{sed} re-reads up to three octal digits following
+the backslash, and generates a single byte from the
+least significant 8 bits of the value. Any subsequent digits
+stand for themselves.  For example:
+
+@example
+\040  @i{@r{is another way of writing a space}}
+\40   @i{@r{is the same, provided there are fewer than 40}}
+      @i{@r{previous capturing subpatterns}}
+\7    @i{@r{is always a back reference}}
+\011  @i{@r{is always a tab}}
+\11   @i{@r{might be a back reference, or another way of writing a tab}}
+\0113 @i{@r{is a tab followed by the character @samp{3}}}
+\113  @i{@r{is the character with octal code 113 (since there}}
+      @i{@r{can be no more than 99 back references)}}
+\377  @i{@r{is a byte consisting entirely of 1 bits (@sc{ascii} 255)}}
+\81   @i{@r{is either a back reference, or a binary zero}}
+      @i{@r{followed by the two characters @samp{81}}}
+@end example
+
+Note that octal values of 100 or greater must not be introduced
+by a leading zero, because no more than three octal
+digits are ever read. Note that this applies only to the LHS 
+pattern; it is not possible yet to specify more than 9 backreferences 
+on the RHS of the `s' command.
+
+All the sequences that define a single byte value can be
+used both inside and outside character classes. In addition,
+inside a character class, the sequence @code{\b} is interpreted
+as the backspace character (hex 08). Outside a character
+class it has a different meaning (see below).
+
+In addition, there are four additional escapes specifying
+generic character classes (like @code{\w} and @code{\W} do):
+
+@cindex Perl-style regular expressions, character classes
+@table @samp
+@item \d
+Matches any decimal digit
+
+@item \D
+Matches any character that is not a decimal digit
+@end table
+
+In Perl mode, these character type sequences can appear both inside and
+outside character classes. Instead, in @sc{posix} mode these sequences
+(as well as @code{\w} and @code{\W}) are treated as two literal characters
+(a backslash and a letter) inside square brackets.
+
+Escaped sequences specifying assertions are also different in
+Perl mode.  An assertion specifies a condition that has to be met
+at a particular point in a match, without consuming any
+characters from the subject string. The use of subpatterns
+for more complicated assertions is described below.  The
+backslashed assertions are
+
+@cindex Perl-style regular expressions, assertions
+@table @samp
+@item \b
+Asserts that the point is at a word boundary.
+A word boundary is a position in the subject string where
+the current character and the previous character do not both
+match @code{\w} or @code{\W} (i.e. one matches @code{\w} and
+the other matches @code{\W}), or the start or end of the string
+if the first or last character matches @code{\w}, respectively.
+
+@item \B
+Asserts that the point is not at a word boundary.
+
+@item \A
+Asserts the matcher is at the start of pattern space (independent
+of multiline mode).
+
+@item \Z
+Asserts the matcher is at the end of pattern space,
+or at a newline before the end of pattern space (independent of
+multiline mode)
+
+@item \z
+Asserts the matcher is at the end of pattern space (independent
+of multiline mode)
+@end table
+
+These assertions may not appear in character classes (but
+note that @code{\b} has a different meaning, namely the
+backspace character, inside a character class).
+Note that Perl mode does not support directly assertions
+for the beginning and the end of word; the @acronym{GNU} extensions
+@code{\<} and @code{\>} achieve this purpose in @sc{posix} mode
+instead.
+
+The @code{\A}, @code{\Z}, and @code{\z} assertions differ
+from the traditional circumflex and dollar sign (described below)
+in that they only ever match at the very start and end of the
+subject string, whatever options are set; in particular @code{\A}
+and @code{\z} are the same as the @acronym{GNU} extensions
+@code{\`} and @code{\'} that are active in @sc{posix} mode.
+
+@node Circumflex/dollar sign/period
+@appendixsec Circumflex, dollar sign, period
+@cindex Perl-style regular expressions, newlines
+
+Outside a character class, in the default matching mode, the
+circumflex character is an assertion which is true only if
+the current matching point is at the start of the subject
+string.  Inside a character class, the circumflex has an entirely
+different meaning (see below).
+
+The circumflex need not be the first character of the pattern if
+a number of alternatives are involved, but it should be the
+first thing in each alternative in which it appears if the
+pattern is ever to match that branch. If all possible alternatives,
+start with a circumflex, that is, if the pattern is
+constrained to match only at the start of the subject, it is
+said to be an @dfn{anchored} pattern. (There are also other constructs
+structs that can cause a pattern to be anchored.)
+
+A dollar sign is an assertion which is true only if the
+current matching point is at the end of the subject string,
+or immediately before a newline character that is the last
+character in the string (by default).  A dollar sign need not be the
+last character of the pattern if a number of alternatives
+are involved, but it should be the last item in any branch
+in which it appears.  A dollar sign has no special meaning in a
+character class.
+
+@cindex Perl-style regular expressions, multiline
+The meanings of the circumflex and dollar sign characters are
+changed if the @code{M} modifier option is used. When this is
+the case, they match immediately after and immediately
+before an internal @code{\n} character, respectively, in addition
+to matching at the start and end of the subject string.  For
+example, the pattern @code{/^abc$/} matches the subject string
+@samp{def\nabc} in multiline mode, but not otherwise.  Consequently,
+patterns that are anchored in single line mode
+because all branches start with @code{^} are not anchored in
+multiline mode.
+
+@cindex Perl-style regular expressions, multiline
+Note that the sequences @code{\A}, @code{\Z}, and @code{\z}
+can be used to match the start and end of the subject in both
+modes, and if all branches of a pattern start with @code{\A}
+is it always anchored, whether the @code{M} modifier is set or not.
+
+@cindex Perl-style regular expressions, single line
+Outside a character class, a dot in the pattern matches any
+one character in the subject, including a non-printing character,
+but not (by default) newline.  If the @code{S} modifier is used,
+dots match newlines as well.  Actually, the handling of
+dot is entirely independent of the handling of circumflex
+and dollar sign, the only relationship being that they both
+involve newline characters. Dot has no special meaning in a
+character class.
+
+@node Square brackets
+@appendixsec Square brackets
+@cindex Perl-style regular expressions, character classes
+
+An opening square bracket introduces a character class, terminated
+by a closing square bracket.  A closing square bracket on its own
+is not special.  If a closing square bracket is required as a
+member of the class, it should be the first data character in
+the class (after an initial circumflex, if present) or escaped with a backslash.
+
+A character class matches a single character in the subject;
+the character must be in the set of characters defined by
+the class, unless the first character in the class is a circumflex,
+in which case the subject character must not be in
+the set defined by the class. If a circumflex is actually
+required as a member of the class, ensure it is not the
+first character, or escape it with a backslash.
+
+For example, the character class [aeiou] matches any lower
+case vowel, while [^aeiou] matches any character that is not
+a lower case vowel. Note that a circumflex is just a convenient
+venient notation for specifying the characters which are in
+the class by enumerating those that are not. It is not an
+assertion: it still consumes a character from the subject
+string, and fails if the current pointer is at the end of
+the string.
+
+@cindex Perl-style regular expressions, case-insensitive
+When caseless matching is set, any letters in a class
+represent both their upper case and lower case versions, so
+for example, a caseless @code{[aeiou]} matches uppercase
+and lowercase @samp{A}s, and a caseless @code{[^aeiou]}
+does not match @samp{A}, whereas a case-sensitive version would.
+
+@cindex Perl-style regular expressions, single line
+@cindex Perl-style regular expressions, multiline
+The newline character is never treated in any special way in
+character classes, whatever the setting of the @code{S} and
+@code{M} options (modifiers) is.  A class such as @code{[^a]} will
+always match a newline.
+
+The minus (hyphen) character can be used to specify a range
+of characters in a character class.  For example, @code{[d-m]}
+matches any letter between d and m, inclusive.  If a minus
+character is required in a class, it must be escaped with a
+backslash or appear in a position where it cannot be interpreted
+as indicating a range, typically as the first or last
+character in the class.
+
+It is not possible to have the literal character @code{]} as the
+end character of a range.  A pattern such as @code{[W-]46]} is
+interpreted as a class of two characters (@code{W} and @code{-})
+followed by a literal string @code{46]}, so it would match
+@samp{W46]} or @samp{-46]}. However, if the @code{]} is escaped
+with a backslash it is interpreted as the end of range, so
+@code{[W-\]46]} is interpreted as a single class containing a
+range followed by two separate characters. The octal or
+hexadecimal representation of @code{]} can also be used to end a range.
+
+Ranges operate in @sc{ascii} collating sequence. They can also be
+used for characters specified numerically, for example
+@code{[\000-\037]}. If a range that includes letters is used when
+caseless matching is set, it matches the letters in either
+case. For example, a caseless @code{[W-c]} is equivalent to
+@code{[][\^_`wxyzabc]}, matched caselessly, and if character
+tables for the French locale are in use, @code{[\xc8-\xcb]}
+matches accented E characters in both cases.
+
+Unlike in @sc{posix} mode, the character types @code{\d},
+@code{\D}, @code{\s}, @code{\S}, @code{\w}, and @code{\W}
+may also appear in a character class, and add the characters
+that they match to the class. For example, @code{[\dABCDEF]} matches any
+hexadecimal digit.  A circumflex can conveniently be used
+with the upper case character types to specify a more restricted
+set of characters than the matching lower case type.
+For example, the class @code{[^\W_]} matches any letter or digit,
+but not underscore.
+
+All non-alphameric characters other than @code{\}, @code{-},
+@code{^} (at the start) and the terminating @code{]}
+are non-special in character classes, but it does no harm
+if they are escaped.
+
+Perl 5.6 supports the @sc{posix} notation for character classes, which
+uses names enclosed by @code{[:} and @code{:]} within the enclosing
+square brackets, and @value{SSED} supports this notation as well.
+For example,
+
+@example
+[01[:alpha:]%]
+@end example
+
+@noindent
+matches @samp{0}, @samp{1}, any alphabetic character, or @samp{%}.
+The supported class names are
+
+@table @code
+@item alnum
+Matches letters and digits
+
+@item alpha
+Matches letters
+
+@item ascii
+Matches character codes 0 - 127
+
+@item cntrl
+Matches control characters
+
+@item digit
+Matches decimal digits (same as \d)
+
+@item graph
+Matches printing characters, excluding space
+
+@item lower
+Matches lower case letters
+
+@item print
+Matches printing characters, including space
+
+@item punct
+Matches printing characters, excluding letters and digits
+
+@item space
+Matches white space (same as \s)
+
+@item upper
+Matches upper case letters
+
+@item word
+Matches ``word'' characters (same as \w)
+
+@item xdigit
+Matches hexadecimal digits
+@end table
+
+The names @code{ascii} and @code{word} are extensions valid only in
+Perl mode.  Another Perl extension is negation, which is
+indicated by a circumflex character after the colon. For example,
+
+@example
+[12[:^digit:]]
+@end example
+
+@noindent
+matches @samp{1}, @samp{2}, or any non-digit.

+@cindex Perl-style regular expressions, single line
+@cindex Perl-style regular expressions, extended
+
+The settings of the @code{I}, @code{M}, @code{S}, @code{X}
+modifiers can be changed from within the pattern by
+a sequence of Perl option letters enclosed between @code{(?}
+and @code{)}. The option letters must be lowercase.
+
+For example, @code{(?im)} sets caseless, multiline matching. It is
+also possible to unset these options by preceding the letter
+with a hyphen; you can also have combined settings and unsettings:
+@code{(?im-sx)} sets caseless and multiline matching,
+while unsets single line matching (for dots) and extended
+whitespace interpretation.  If a letter appears both before
+and after the hyphen, the option is unset.
+
+The scope of these option changes depends on where in the
+pattern the setting occurs. For settings that are outside
+any subpattern (defined below), the effect is the same as if
+the options were set or unset at the start of matching. The
+following patterns all behave in exactly the same way:
+
+@example
+(?i)abc
+a(?i)bc
+ab(?i)c
+abc(?i)
+@end example
+
+which in turn is the same as specifying the pattern abc with
+the @code{I} modifier.  In other words, ``top level'' settings
+apply to the whole pattern (unless there are other
+changes inside subpatterns). If there is more than one setting
+of the same option at top level, the rightmost setting
+is used.
+
+If an option change occurs inside a subpattern, the effect
+is different.  This is a change of behaviour in Perl 5.005.
+An option change inside a subpattern affects only that part
+of the subpattern @emph{that follows} it, so
+
+@example
+(a(?i)b)c
+@end example
+
+@noindent
+matches abc and aBc and no other  strings  (assuming
+case-sensitive matching is used).  By this means, options can
+be made to have different settings in different parts of the
+pattern.  Any changes made in one alternative do carry on
+into subsequent branches within the same subpattern.  For
+example,
+
+@example
+(a(?i)b|c)
+@end example
+
+@noindent
+matches @samp{ab}, @samp{aB}, @samp{c}, and @samp{C},
+even though when matching @samp{C} the first branch is
+abandoned before the option setting.
+This is because the effects of option settings happen at
+compile time. There would be some very weird behaviour otherwise.
+
+@ignore
+There are two PCRE-specific options PCRE_UNGREEDY and PCRE_EXTRA
+that can be changed in the same way as the Perl-compatible options by
+using the characters U and X respectively.  The (?X) flag
+setting is special in that it must always occur earlier in
+the pattern than any of the additional features it turns on,
+even when it is at top level. It is best put at the start.
+@end ignore
+
+
+@node Non-capturing subpatterns
+@appendixsec Non-capturing subpatterns
+@cindex Perl-style regular expressions, non-capturing subpatterns
+
+Marking part of a pattern as a subpattern does two things.
+On one hand, it localizes a set of alternatives; on the other
+hand, it sets up the subpattern as a capturing subpattern (as
+defined above).  The subpattern can be backreferenced and
+referenced in the right side of @code{s} commands.
+
+For example, if the string @samp{the red king} is matched against
+the pattern
+
+@example
+the ((red|white) (king|queen))
+@end example
+
+@noindent
+the captured substrings are @samp{red king}, @samp{red},
+and @samp{king}, and are numbered 1, 2, and 3.
+
+The fact that plain parentheses fulfil two functions is not
+always helpful.  There are often times when a grouping
+subpattern is required without a capturing requirement.  If an
+opening parenthesis is followed by @code{?:}, the subpattern does
+not do any capturing, and is not counted when computing the
+number of any subsequent capturing subpatterns. For example,
+if the string @samp{the white queen} is matched against the pattern
+
+@example
+the ((?:red|white) (king|queen))
+@end example
+
+@noindent
+the captured substrings are @samp{white queen} and @samp{queen},
+and are numbered 1 and 2. The maximum number of captured
+substrings is 99, while the maximum number of all subpatterns,
+both capturing and non-capturing, is 200.
+
+As a convenient shorthand, if any option settings are
+equired at the start of a non-capturing subpattern, the
+option letters may appear between the @code{?} and the
+@code{:}.  Thus the two patterns
+
+@example
+(?i:saturday|sunday)
+(?:(?i)saturday|sunday)
+@end example
+
+@noindent
+match exactly the same set of strings.  Because alternative
+branches are tried from left to right, and options are not
+reset until the end of the subpattern is reached, an option
+setting in one branch does affect subsequent branches, so
+the above patterns match @samp{SUNDAY} as well as @samp{Saturday}.
+
+
+@node Repetition
+@appendixsec Repetition
+@cindex Perl-style regular expressions, repetitions
+
+Repetition is specified by quantifiers, which can follow any
+of the following items:
+
+@itemize @bullet
+@item
+a single character, possibly escaped
+
+@item
+the @code{.} special character
+
+@item
+a character class
+
+@item
+a back reference (see next section)
+
+@item
+a parenthesized subpattern (unless it is an assertion; @pxref{Assertions})
+@end itemize
+
+The general repetition quantifier specifies a minimum and
+maximum number of permitted matches, by giving the two
+numbers in curly brackets (braces), separated by a comma.
+The numbers must be less than 65536, and the first must be
+less than or equal to the second. For example:
+
+@example
+z@{2,4@}
+@end example
+
+@noindent
+matches @samp{zz}, @samp{zzz}, or @samp{zzzz}. A closing brace on its own
+is not a special character. If the second number is omitted,
+but the comma is present, there is no upper limit; if the
+second number and the comma are both omitted, the quantifier
+specifies an exact number of required matches. Thus
+
+@example
+[aeiou]@{3,@}
+@end example
+
+@noindent
+matches at least 3 successive vowels, but may match many
+more, while
+
+@example
+\d@{8@}
+@end example
+
+@noindent
+matches exactly 8 digits.  An opening curly bracket that
+appears in a position where a quantifier is not allowed, or
+one that does not match the syntax of a quantifier, is taken
+as a literal character. For example, @{,6@} is not a quantifier,
+but a literal string of four characters.@footnote{It
+raises an error if @option{-R} is not used.}
+
+The quantifier @samp{@{0@}} is permitted, causing the expression to
+behave as if the previous item and the quantifier were not
+present.
+
+For convenience (and historical compatibility) the three
+most common quantifiers have single-character abbreviations:
+
+@table @code
+@item *
+is equivalent to @{0,@}
+
+@item +
+is equivalent to @{1,@}
+
+@item ?
+is equivalent to @{0,1@}
+@end table
+
+It is possible to construct infinite loops by following a
+subpattern that can match no characters with a quantifier
+that has no upper limit, for example:
+
+@example
+(a?)*
+@end example
+
+Earlier versions of Perl used to give an error at
+compile time for such patterns. However, because there are
+cases where this can be useful, such patterns are now
+accepted, but if any repetition of the subpattern does in
+fact match no characters, the loop is forcibly broken.
+
+@cindex Greedy regular expression matching
+@cindex Perl-style regular expressions, stingy repetitions
+By default, the quantifiers are @dfn{greedy} like in @sc{posix}
+mode, that is, they match as much as possible (up to the maximum
+number of permitted times), without causing the rest of the
+pattern to fail. The classic example of where this gives problems
+is in trying to match comments in C programs. These appear between
+the sequences @code{/*} and @code{*/} and within the sequence, individual
+@code{*} and @code{/} characters may appear. An attempt to match C
+comments by applying the pattern
+
+@example
+/\*.*\*/
+@end example
+
+@noindent
+to the string
+
+@example
+/* first command */ not comment /* second comment */
+@end example
+
+@noindent
+
+fails, because it matches the entire string owing to the
+greediness of the @code{.*} item.
+
+However, if a quantifier is followed by a question mark, it
+ceases to be greedy, and instead matches the minimum number
+of times possible, so the pattern @code{/\*.*?\*/}
+does the right thing with the C comments. The meaning of the
+various quantifiers is not otherwise changed, just the preferred
+number of matches.  Do not confuse this use of question
+mark with its use as a quantifier in its own right.
+Because it has two uses, it can sometimes appear doubled, as in
+
+@example
+\d??\d
+@end example
+
+which matches one digit by preference, but can match two if
+that is the only way the rest of the pattern matches.
+
+Note that greediness does not matter when specifying addresses,
+but can be nevertheless used to improve performance.
+
+@ignore
+If the PCRE_UNGREEDY option is set (an option which is not
+available in Perl), the quantifiers are not greedy by
+default, but individual ones can be made greedy by following
+them with a question mark. In other words, it inverts the
+default behaviour.
+@end ignore
+
+When a parenthesized subpattern is quantified with a minimum
+repeat count that is greater than 1 or with a limited maximum,
+more store is required for the compiled pattern, in
+proportion to the size of the minimum or maximum.
+
+@cindex Perl-style regular expressions, single line
+If a pattern starts with @code{.*} or @code{.@{0,@}} and the
+@code{S} modifier is used, the pattern is implicitly anchored,
+because whatever follows will be tried against every character
+position in the subject string, so there is no point in
+retrying the overall match at any position after the first.
+PCRE treats such a pattern as though it were preceded by \A.
+
+When a capturing subpattern is repeated, the value captured
+is the substring that matched the final iteration. For example,
+after
+
+@example
+(tweedle[dume]@{3@}\s*)+
+@end example
+
+@noindent
+has matched @samp{tweedledum tweedledee} the value of the
+captured substring is @samp{tweedledee}.  However, if there are
+nested capturing subpatterns, the corresponding captured
+values may have been set in previous iterations. For example,
+after
+
+@example
+/(a|(b))+/
+@end example
+
+matches @samp{aba}, the value of the second captured substring is
+@samp{b}.
+
+@node Backreferences
+@appendixsec Backreferences
+@cindex Perl-style regular expressions, backreferences
+
+Outside a character class, a backslash followed by a digit
+greater than 0 (and possibly further digits) is a back
+reference to a capturing subpattern earlier (i.e.  to its
+left) in the pattern, provided there have been that many
+previous capturing left parentheses.
+
+However, if the decimal number following the backslash is
+less than 10, it is always taken as a back reference, and
+causes an error only if there are not that many capturing
+left parentheses in the entire pattern. In other words, the
+parentheses that are referenced need not be to the left of
+the reference for numbers less than 10. @ref{Backslash}
+for further details of the handling of digits following a backslash.
+
+A back reference matches whatever actually matched the capturing
+subpattern in the current subject string, rather than
+anything matching the subpattern itself. So the pattern
+
+@example
+(sens|respons)e and \1ibility
+@end example
+
+@noindent
+matches @samp{sense and sensibility} and @samp{response and responsibility},
+but not @samp{sense and responsibility}. If caseful
+matching is in force at the time of the back reference, the
+case of letters is relevant. For example,
+
+@example
+((?i)blah)\s+\1
+@end example
+
+@noindent
+matches @samp{blah blah} and @samp{Blah Blah}, but not
+@samp{BLAH blah}, even though the original capturing
+subpattern is matched caselessly.
+
+There may be more than one back reference to the same subpattern.
+Also, if a subpattern has not actually been used in a
+particular match, any back references to it always fail. For
+example, the pattern
+
+@example
+(a|(bc))\2
+@end example
+
+@noindent
+always fails if it starts to match @samp{a} rather than
+@samp{bc}.  Because there may be up to 99 back references, all
+digits following the backslash are taken as part of a potential
+back reference number; this is different from what happens
+in @sc{posix} mode. If the pattern continues with a digit
+character, some delimiter must be used to terminate the back
+reference.  If the @code{X} modifier option is set, this can be
+whitespace.  Otherwise an empty comment can be used, or the
+following character can be expressed in hexadecimal or octal.
+Note that this applies only to the LHS pattern; it is
+not possible yet to specify more than 9 backreferences on the 
+RHS of the `s' command. 
+
+A back reference that occurs inside the parentheses to which
+it refers fails when the subpattern is first used, so, for
+example, @code{(a\1)} never matches.  However, such references
+can be useful inside repeated subpatterns. For example, the
+pattern
+
+@example
+(a|b\1)+
+@end example
+
+@noindent
+matches any number of @samp{a}s and also @samp{aba}, @samp{ababbaa},
+etc. At each iteration of the subpattern, the back reference matches
+the character string corresponding to the previous iteration.  In
+order for this to work, the pattern must be such that the first
+iteration does not need to match the back reference.  This can be
+done using alternation, as in the example above, or by a
+quantifier with a minimum of zero.
+
+@node Assertions
+@appendixsec Assertions
+@cindex Perl-style regular expressions, assertions
+@cindex Perl-style regular expressions, asserting subpatterns
+
+An assertion is a test on the characters following or
+preceding the current matching point that does not actually
+consume any characters. The simple assertions coded as @code{\b},
+@code{\B}, @code{\A}, @code{\Z}, @code{\z}, @code{^} and @code{$}
+are described above. More complicated assertions are coded as
+subpatterns.  There are two kinds: those that look ahead of the
+current position in the subject string, and those that look behind it.
+
+@cindex Perl-style regular expressions, lookahead subpatterns
+An assertion subpattern is matched in the normal way, except
+that it does not cause the current matching position to be
+changed. Lookahead assertions start with @code{(?=} for positive
+assertions and @code{(?!} for negative assertions. For example,
+
+@example
+\w+(?=;)
+@end example
+
+@noindent
+matches a word followed by a semicolon, but does not include
+the semicolon in the match, and
+
+@example
+foo(?!bar)
+@end example
+
+@noindent
+matches any occurrence of @samp{foo} that is not followed by
+@samp{bar}.
+
+Note that the apparently similar pattern
+
+@example
+(?!foo)bar
+@end example
+
+@noindent
+@cindex Perl-style regular expressions, lookbehind subpatterns
+finds any occurrence of @samp{bar} even if it is preceded by
+@samp{foo}, because the assertion @code{(?!foo)} is always true
+when the next three characters are @samp{bar}. A lookbehind
+assertion is needed to achieve this effect.
+Lookbehind assertions start with @code{(?<=} for positive
+assertions and @code{(?<!} for negative assertions. So,
+
+@example
+(?<!foo)bar
+@end example
+
+achieves the required effect of finding an occurrence of
+@samp{bar} that is not preceded by @samp{foo}. The contents of a
+lookbehind assertion are restricted
+such that all the strings it matches must have a fixed
+length.  However, if there are several alternatives, they do
+not all have to have the same fixed length.  This is an extension
+compared with Perl 5.005, which requires all branches to match
+the same length of string. Thus
+
+@example
+(?<=dogs|cats|)
+@end example
+
+@noindent
+is permitted, but the apparently equivalent regular expression
+
+@example
+(?<!dogs?|cats?)
+@end example
+
+@noindent
+causes an error at compile time. Branches that match different
+length strings are permitted only at the top level of
+a lookbehind assertion: an assertion such as
+
+@example
+(?<=ab(c|de))
+@end example
+
+@noindent
+is not permitted, because its single top-level branch can
+match two different lengths, but it is acceptable if rewritten
+to use two top-level branches:
+
+@example
+(?<=abc|abde)
+@end example
+
+All this is required because lookbehind assertions simply
+move the current position back by the alternative's fixed
+width and then try to match.  If there are
+insufficient characters before the current position, the
+match is deemed to fail.  Lookbehinds, in conjunction with
+non-backtracking subpatterns can be particularly useful for
+matching at the ends of strings; an example is given at the end
+of the section on non-backtracking subpatterns.
+
+Several assertions (of any sort) may occur in succession.
+For example,
+
+@example
+(?<=\d@{3@})(?<!999)foo
+@end example
+
+@noindent
+matches @samp{foo} preceded by three digits that are not @samp{999}.
+Notice that each of the assertions is applied independently
+at the same point in the subject string. First there is a
+check that the previous three characters are all digits, and
+then there is a check that the same three characters are not
+@samp{999}.  This pattern does not match @samp{foo} preceded by six
+characters, the first of which are digits and the last three
+of which are not @samp{999}.  For example, it doesn't match
+@samp{123abcfoo}. A pattern to do that is
+
+@example
+(?<=\d@{3@}...)(?<!999)foo
+@end example
+
+@noindent
+This time the first assertion looks at the preceding six
+characters, checking that the first three are digits, and
+then the second assertion checks that the preceding three
+characters are not @samp{999}.  Actually, assertions can be
+nested in any combination, so one can write this as 
+
+@example
+(?<=\d@{3@}(?!999)...)foo
+@end example
+
+or
+
+@example
+(?<=\d@{3@}...(?<!999))foo
+@end example
+
+@noindent
+both of which might be considered more readable.
+
+Assertion subpatterns are not capturing subpatterns, and may
+not be repeated, because it makes no sense to assert the
+same thing several times. If any kind of assertion contains
+capturing subpatterns within it, these are counted for the
+purposes of numbering the capturing subpatterns in the whole
+pattern.  However, substring capturing is carried out only
+for positive assertions, because it does not make sense for
+negative assertions.
+
+Assertions count towards the maximum of 200 parenthesized
+subpatterns.
+
+@node Non-backtracking subpatterns
+@appendixsec Non-backtracking subpatterns
+@cindex Perl-style regular expressions, non-backtracking subpatterns
+
+With both maximizing and minimizing repetition, failure of
+what follows normally causes the repeated item to be evaluated
+again to see if a different number of repeats allows the
+rest of the pattern to match. Sometimes it is useful to
+prevent this, either to change the nature of the match, or
+to cause it fail earlier than it otherwise might, when the
+author of the pattern knows there is no point in carrying
+on.
+
+Consider, for example, the pattern @code{\d+foo} when applied to
+the subject line
+
+@example
+123456bar
+@end example
+
+After matching all 6 digits and then failing to match @samp{foo},
+the normal action of the matcher is to try again with only 5
+digits matching the @code{\d+} item, and then with 4, and so on,
+before ultimately failing. Non-backtracking subpatterns
+provide the means for specifying that once a portion of the
+pattern has matched, it is not to be re-evaluated in this way,
+so the matcher would give up immediately on failing to match
+@samp{foo} the first time.  The notation is another kind of special
+parenthesis, starting with @code{(?>} as in this example:
+
+@example
+(?>\d+)bar
+@end example
+
+This kind of parenthesis ``locks up'' the part of the pattern
+it contains once it has matched, and a failure further into
+the pattern is prevented from backtracking into it.
+Backtracking past it to previous items, however, works as
+normal.
+
+Non-backtracking subpatterns are not capturing subpatterns.  Simple
+cases such as the above example can be thought of as a maximizing
+repeat that must swallow everything it can.  So,
+while both @code{\d+} and @code{\d+?} are prepared to adjust the number of
+digits they match in order to make the rest of the pattern
+match, @code{(?>\d+)} can only match an entire sequence of digits.
+
+This construction can of course contain arbitrarily complicated
+subpatterns, and it can be nested.
+
+@cindex Perl-style regular expressions, lookbehind subpatterns
+Non-backtracking subpatterns can be used in conjunction with look-behind
+assertions to specify efficient matching at the end
+of the subject string. Consider a simple pattern such as
+
+@example
+abcd$
+@end example
+
+@noindent
+when applied to a long string which does not match.  Because
+matching proceeds from left to right, @command{sed} will look for
+each @samp{a} in the subject and then see if what follows matches
+the rest of the pattern. If the pattern is specified as
+
+@example
+^.*abcd$
+@end example
+
+@noindent
+the initial @code{.*} matches the entire string at first, but when
+this fails (because there is no following @samp{a}), it backtracks
+to match all but the last character, then all but the
+last two characters, and so on. Once again the search for
+@samp{a} covers the entire string, from right to left, so we are
+no better off. However, if the pattern is written as
+
+@example
+^(?>.*)(?<=abcd)
+@end example
+
+there can be no backtracking for the .* item; it can match
+only the entire string. The subsequent lookbehind assertion
+does a single test on the last four characters. If it fails,
+the match fails immediately. For long strings, this approach
+makes a significant difference to the processing time.
+
+When a pattern contains an unlimited repeat inside a subpattern
+that can itself be repeated an unlimited number of
+times, the use of a once-only subpattern is the only way to
+avoid some failing matches taking a very long time
+indeed.@footnote{Actually, the matcher embedded in @value{SSED}
+tries to do something for this in the simplest cases,
+like @code{([^b]*b)*}.  These cases are actually quite
+common: they happen for example in a regular expression
+like @code{\/\*([^*]*\*)*\/} which matches C comments.}
+
+The pattern
+
+@example
+(\D+|<\d+>)*[!?]
+@end example
+
+([^0-9<]+<(\d+>)?)*[!?]
+
+@noindent
+matches an unlimited number of substrings that either consist
+of non-digits, or digits enclosed in angular brackets, followed by
+an exclamation or question mark. When it matches, it runs quickly.
+However, if it is applied to
+
+@example
+aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
+@end example
+
+@noindent
+it takes a long time before reporting failure.  This is
+because the string can be divided between the two repeats in
+a large number of ways, and all have to be tried.@footnote{The
+example used @code{[!?]} rather than a single character at the end,
+because both @value{SSED} and Perl have an optimization that allows
+for fast failure when a single character is used. They
+remember the last single character that is required for a
+match, and fail early if it is not present in the string.}
+
+If the pattern is changed to
+
+@example
+((?>\D+)|<\d+>)*[!?]
+@end example
+
+sequences of non-digits cannot be broken, and failure happens
+quickly.
+
+@node Conditional subpatterns
+@appendixsec Conditional subpatterns
+@cindex Perl-style regular expressions, conditional subpatterns
+
+It is possible to cause the matching process to obey a subpattern
+conditionally or to choose between two alternative
+subpatterns, depending on the result of an assertion, or
+whether a previous capturing subpattern matched or not. The
+two possible forms of conditional subpattern are
+
+@example
+(?(@var{condition})@var{yes-pattern})
+(?(@var{condition})@var{yes-pattern}|@var{no-pattern})
+@end example
+
+If the condition is satisfied, the yes-pattern is used; otherwise
+the no-pattern (if present) is used. If there are more than two
+alternatives in the subpattern, a compile-time error occurs.
+
+There are two kinds of condition. If the text between the
+parentheses consists of a sequence of digits, the condition
+is satisfied if the capturing subpattern of that number has
+previously matched.  The number must be greater than zero.
+Consider the following pattern, which contains non-significant
+white space to make it more readable (assume the @code{X} modifier)
+and to divide it into three parts for ease of discussion:
+
+@example
+( \( )?   [^()]+   (?(1) \) )
+@end example
+
+The first part matches an optional opening parenthesis, and
+if that character is present, sets it as the first captured
+substring. The second part matches one or more characters
+that are not parentheses. The third part is a conditional
+subpattern that tests whether the first set of parentheses
+matched or not.  If they did, that is, if subject started
+with an opening parenthesis, the condition is true, and so
+the yes-pattern is executed and a closing parenthesis is
+required. Otherwise, since no-pattern is not present, the
+subpattern matches nothing.  In other words, this pattern
+matches a sequence of non-parentheses, optionally enclosed
+in parentheses.
+
+@cindex Perl-style regular expressions, lookahead subpatterns
+If the condition is not a sequence of digits, it must be an
+assertion.  This may be a positive or negative lookahead or
+lookbehind assertion. Consider this pattern, again containing
+non-significant white space, and with the two alternatives
+on the second line:
+
+@example
+(?(?=...[a-z])
+   \d\d-[a-z]@{3@}-\d\d |
+   \d\d-\d\d-\d\d )
+@end example
+
+The condition is a positive lookahead assertion that matches
+a letter that is three characters away from the current point.
+If a letter is found, the subject is matched against the first
+alternative @samp{@var{dd}-@var{aaa}-@var{dd}} (where @var{aaa} are
+letters and @var{dd} are digits); otherwise it is matched against 
+the second alternative, @samp{@var{dd}-@var{dd}-@var{dd}}.
+
+
+@node Recursive patterns
+@appendixsec Recursive patterns
+@cindex Perl-style regular expressions, recursive patterns
+@cindex Perl-style regular expressions, recursion
+
+Consider the problem of matching a string in parentheses,
+allowing for unlimited nested parentheses. Without the use
+of recursion, the best that can be done is to use a pattern
+that matches up to some fixed depth of nesting. It is not
+possible to handle an arbitrary nesting depth. Perl 5.6 has
+provided an experimental facility that allows regular
+expressions to recurse (amongst other things). It does this
+by interpolating Perl code in the expression at run time,
+and the code can refer to the expression itself. A Perl pattern
+tern to solve the parentheses problem can be created like
+this:
+
+@example
+$re = qr@{\( (?: (?>[^()]+) | (?p@{$re@}) )* \)@}x;
+@end example
+
+The @code{(?p@{...@})} item interpolates Perl code at run time,
+and in this case refers recursively to the pattern in which it
+appears. Obviously, @command{sed} cannot support the interpolation of
+Perl code.  Instead, the special item @code{(?R)} is provided for
+the specific case of recursion. This pattern solves the
+parentheses problem (assume the @code{X} modifier option is used
+so that white space is ignored):
+
+@example
+\( ( (?>[^()]+) | (?R) )* \)
+@end example
+
+First it matches an opening parenthesis. Then it matches any
+number of substrings which can either be a sequence of
+non-parentheses, or a recursive match of the pattern itself
+(i.e. a correctly parenthesized substring). Finally there is
+a closing parenthesis.
+
+This particular example pattern contains nested unlimited
+repeats, and so the use of a non-backtracking subpattern for
+matching strings of non-parentheses is important when applying
+the pattern to strings that do not match. For example, when
+it is applied to
+
+@example
+(aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa()
+@end example
+
+it yields a ``no match'' response quickly. However, if a
+standard backtracking subpattern is not used, the match runs
+for a very long time indeed because there are so many different
+ways the @code{+} and @code{*} repeats can carve up the subject,
+and all have to be tested before failure can be reported.
+
+The values set for any capturing subpatterns are those from
+the outermost level of the recursion at which the subpattern
+value is set. If the pattern above is matched against
+
+@example
+(ab(cd)ef)
+@end example
+
+@noindent
+the value for the capturing parentheses is @samp{ef}, which is
+the last value taken on at the top level.
+
+@node Comments
+@appendixsec Comments
+@cindex Perl-style regular expressions, comments
+
+The sequence (?# marks the start of a comment which continues
+ues up to the next closing parenthesis. Nested parentheses
+are not permitted. The characters that make up a comment
+play no part in the pattern matching at all.
+
+@cindex Perl-style regular expressions, extended
+If the @code{X} modifier option is used, an unescaped @code{#} character
+outside a character class introduces a comment that continues
+up to the next newline character in the pattern.

+.ds Sd \fISed\fP
+\*(Sd is a stream editor.
+A stream editor is used to perform basic text
+transformations on an input stream
+(a file or input from a pipeline).
+While in some ways similar to an editor which
+permits scripted edits (such as \fIed\fP),
+\*(sd works by making only one pass over the
+input(s), and is consequently more efficient.

+.SH
+Addresses
+\*(Sd commands can be given with no addresses, in which
+case the command will be executed for all input lines;
+with one address, in which case the command will only be executed
+for input lines which match that address; or with two
+addresses, in which case the command will be executed
+for all input lines which match the inclusive range of
+lines starting from the first address and continuing to
+the second address.
+Three things to note about address ranges:
+the syntax is
+.IR addr1 , addr2
+(i.e., the addresses are separated by a comma);
+the line which
+.I addr1
+matched will always be accepted,
+even if
+.I addr2
+selects an earlier line;
+and if
+.I addr2
+is a
+.IR regexp ,
+it will not be tested against the line that
+.I addr1
+matched.
+.PP
+After the address (or address-range),
+and before the command, a
+.B !
+may be inserted,
+which specifies that the command shall only be
+executed if the address (or address-range) does
+.B not
+match.
+.PP
+The following address types are supported:
+.TP
+.I number
+Match only the specified line
+.IR number
+(which increments cumulatively across files, unless the
+.B -s
+option is specified on the command line).
+.TP
+.IR first ~ step
+Match every
+.IR step 'th
+line starting with line
+.IR first .
+For example, ``sed -n 1~2p'' will print all the odd-numbered lines in
+the input stream, and the address 2~5 will match every fifth line,
+starting with the second.
+.I first
+can be zero; in this case, \*(sd operates as if it were equal to
+.IR step .
+(This is an extension.)
+.TP
+$
+Match the last line.
+.TP
+.RI / regexp /
+Match lines matching the regular expression
+.IR regexp .
+.TP
+.BI \fR\e\fPc regexp c
+Match lines matching the regular expression
+.IR regexp .
+The
+.B c
+may be any character.
+.PP
+GNU \*(sd also supports some special 2-address forms:
+.TP
+.RI 0, addr2
+Start out in "matched first address" state, until
+.I addr2
+is found.
+This is similar to
+.RI 1, addr2 ,
+except that if
+.I addr2
+matches the very first line of input the
+.RI 0, addr2
+form will be at the end of its range, whereas the
+.RI 1, addr2
+form will still be at the beginning of its range.
+This works only when
+.I addr2
+is a regular expression.
+.TP
+.IR addr1 ,+ N
+Will match
+.I addr1
+and the
+.I N
+lines following
+.IR addr1 .
+.TP
+.IR addr1 ,~ N
+Will match
+.I addr1
+and the lines following
+.I addr1
+until the next line whose input line number is a multiple of
+.IR N .
+.SH "REGULAR EXPRESSIONS"
+POSIX.2 BREs
+.I should
+be supported, but they aren't completely because of performance
+problems.
+The
+.B \en
+sequence in a regular expression matches the newline character,
+and similarly for
+.BR \ea ,
+.BR \et ,
+and other sequences.

+1 Introduction
+**************
+
+`sed' is a stream editor.  A stream editor is used to perform basic text
+transformations on an input stream (a file or input from a pipeline).
+While in some ways similar to an editor which permits scripted edits
+(such as `ed'), `sed' works by making only one pass over the input(s),
+and is consequently more efficient.  But it is `sed''s ability to
+filter text in a pipeline which particularly distinguishes it from
+other types of editors.
+
+
+File: sed.info,  Node: Invoking sed,  Next: sed Programs,  Prev: Introduction,  Up: Top
+
+2 Invocation
+************
+
+Normally `sed' is invoked like this:
+
+     sed SCRIPT INPUTFILE...
+
+   The full format for invoking `sed' is:
+
+     sed OPTIONS... [SCRIPT] [INPUTFILE...]
+
+   If you do not specify INPUTFILE, or if INPUTFILE is `-', `sed'
+filters the contents of the standard input.  The SCRIPT is actually the
+first non-option parameter, which `sed' specially considers a script
+and not an input file if (and only if) none of the other OPTIONS
+specifies a script to be executed, that is if neither of the `-e' and
+`-f' options is specified.
+
+   `sed' may be invoked with the following command-line options:
+
+`--version'
+     Print out the version of `sed' that is being run and a copyright
+     notice, then exit.
+
+`--help'
+     Print a usage message briefly summarizing these command-line
+     options and the bug-reporting address, then exit.
+
+`-n'
+`--quiet'
+`--silent'
+     By default, `sed' prints out the pattern space at the end of each
+     cycle through the script (*note How `sed' works: Execution Cycle.).
+     These options disable this automatic printing, and `sed' only
+     produces output when explicitly told to via the `p' command.
+
+`-e SCRIPT'
+`--expression=SCRIPT'
+     Add the commands in SCRIPT to the set of commands to be run while
+     processing the input.
+
+`-f SCRIPT-FILE'
+`--file=SCRIPT-FILE'
+     Add the commands contained in the file SCRIPT-FILE to the set of
+     commands to be run while processing the input.
+
+`-i[SUFFIX]'
+`--in-place[=SUFFIX]'
+     This option specifies that files are to be edited in-place.  GNU
+     `sed' does this by creating a temporary file and sending output to
+     this file rather than to the standard output.(1).
+
+     This option implies `-s'.
+
+     When the end of the file is reached, the temporary file is renamed
+     to the output file's original name.  The extension, if supplied,
+     is used to modify the name of the old file before renaming the
+     temporary file, thereby making a backup copy(2)).
+
+     This rule is followed: if the extension doesn't contain a `*',
+     then it is appended to the end of the current filename as a
+     suffix; if the extension does contain one or more `*' characters,
+     then _each_ asterisk is replaced with the current filename.  This
+     allows you to add a prefix to the backup file, instead of (or in
+     addition to) a suffix, or even to place backup copies of the
+     original files into another directory (provided the directory
+     already exists).
+
+     If no extension is supplied, the original file is overwritten
+     without making a backup.
+
+`-l N'
+`--line-length=N'
+     Specify the default line-wrap length for the `l' command.  A
+     length of 0 (zero) means to never wrap long lines.  If not
+     specified, it is taken to be 70.
+
+`--posix'
+     GNU `sed' includes several extensions to POSIX sed.  In order to
+     simplify writing portable scripts, this option disables all the
+     extensions that this manual documents, including additional
+     commands.  Most of the extensions accept `sed' programs that are
+     outside the syntax mandated by POSIX, but some of them (such as
+     the behavior of the `N' command described in *note Reporting
+     Bugs::) actually violate the standard.  If you want to disable
+     only the latter kind of extension, you can set the
+     `POSIXLY_CORRECT' variable to a non-empty value.
+
+`-b'
+`--binary'
+     This option is available on every platform, but is only effective
+     where the operating system makes a distinction between text files
+     and binary files.  When such a distinction is made--as is the case
+     for MS-DOS, Windows, Cygwin--text files are composed of lines
+     separated by a carriage return _and_ a line feed character, and
+     `sed' does not see the ending CR.  When this option is specified,
+     `sed' will open input files in binary mode, thus not requesting
+     this special processing and considering lines to end at a line
+     feed.
+
+`--follow-symlinks'
+     This option is available only on platforms that support symbolic
+     links and has an effect only if option `-i' is specified.  In this
+     case, if the file that is specified on the command line is a
+     symbolic link, `sed' will follow the link and edit the ultimate
+     destination of the link.  The default behavior is to break the
+     symbolic link, so that the link destination will not be modified.
+
+`-r'
+`--regexp-extended'
+     Use extended regular expressions rather than basic regular
+     expressions.  Extended regexps are those that `egrep' accepts;
+     they can be clearer because they usually have less backslashes,
+     but are a GNU extension and hence scripts that use them are not
+     portable.  *Note Extended regular expressions: Extended regexps.
+
+`-s'
+`--separate'
+     By default, `sed' will consider the files specified on the command
+     line as a single continuous long stream.  This GNU `sed' extension
+     allows the user to consider them as separate files: range
+     addresses (such as `/abc/,/def/') are not allowed to span several
+     files, line numbers are relative to the start of each file, `$'
+     refers to the last line of each file, and files invoked from the
+     `R' commands are rewound at the start of each file.
+
+`-u'
+`--unbuffered'
+     Buffer both input and output as minimally as practical.  (This is
+     particularly useful if the input is coming from the likes of `tail
+     -f', and you wish to see the transformed output as soon as
+     possible.)
+
+`-z'
+`--null-data'
+`--zero-terminated'
+     Treat the input as a set of lines, each terminated by a zero byte
+     (the ASCII `NUL' character) instead of a newline.  This option can
+     be used with commands like `sort -z' and `find -print0' to process
+     arbitrary file names.
+
+   If no `-e', `-f', `--expression', or `--file' options are given on
+the command-line, then the first non-option argument on the command
+line is taken to be the SCRIPT to be executed.
+
+   If any command-line parameters remain after processing the above,
+these parameters are interpreted as the names of input files to be
+processed.  A file name of `-' refers to the standard input stream.
+The standard input will be processed if no file names are specified.
+
+   ---------- Footnotes ----------
+
+   (1) This applies to commands such as `=', `a', `c', `i', `l', `p'.
+You can still write to the standard output by using the `w' or `W'
+commands together with the `/dev/stdout' special file
+
+   (2) Note that GNU `sed' creates the backup file whether or not any
+output is actually changed.

+
+3 `sed' Programs
+****************
+
+A `sed' program consists of one or more `sed' commands, passed in by
+one or more of the `-e', `-f', `--expression', and `--file' options, or
+the first non-option argument if zero of these options are used.  This
+document will refer to "the" `sed' script; this is understood to mean
+the in-order catenation of all of the SCRIPTs and SCRIPT-FILEs passed
+in.
+
+   Commands within a SCRIPT or SCRIPT-FILE can be separated by
+semicolons (`;') or newlines (ASCII 10).  Some commands, due to their
+syntax, cannot be followed by semicolons working as command separators
+and thus should be terminated with newlines or be placed at the end of
+a SCRIPT or SCRIPT-FILE.  Commands can also be preceded with optional
+non-significant whitespace characters.
+
+   Each `sed' command consists of an optional address or address range,
+followed by a one-character command name and any additional
+command-specific code.

+
+3.1 How `sed' Works
+===================
+
+`sed' maintains two data buffers: the active _pattern_ space, and the
+auxiliary _hold_ space. Both are initially empty.
+
+   `sed' operates by performing the following cycle on each line of
+input: first, `sed' reads one line from the input stream, removes any
+trailing newline, and places it in the pattern space.  Then commands
+are executed; each command can have an address associated to it:
+addresses are a kind of condition code, and a command is only executed
+if the condition is verified before the command is to be executed.
+
+   When the end of the script is reached, unless the `-n' option is in
+use, the contents of pattern space are printed out to the output
+stream, adding back the trailing newline if it was removed.(1) Then the
+next cycle starts for the next input line.
+
+   Unless special commands (like `D') are used, the pattern space is
+deleted between two cycles. The hold space, on the other hand, keeps
+its data between cycles (see commands `h', `H', `x', `g', `G' to move
+data between both buffers).
+
+   ---------- Footnotes ----------
+
+   (1) Actually, if `sed' prints a line without the terminating
+newline, it will nevertheless print the missing newline as soon as more
+text is sent to the same output stream, which gives the "least expected
+surprise" even though it does not make commands like `sed -n p' exactly
+identical to `cat'.
+
+
+File: sed.info,  Node: Addresses,  Next: Regular Expressions,  Prev: Execution Cycle,  Up: sed Programs
+
+3.2 Selecting lines with `sed'
+==============================
+
+Addresses in a `sed' script can be in any of the following forms:
+`NUMBER'
+     Specifying a line number will match only that line in the input.
+     (Note that `sed' counts lines continuously across all input files
+     unless `-i' or `-s' options are specified.)
+
+`FIRST~STEP'
+     This GNU extension matches every STEPth line starting with line
+     FIRST.  In particular, lines will be selected when there exists a
+     non-negative N such that the current line-number equals FIRST + (N
+     * STEP).  Thus, to select the odd-numbered lines, one would use
+     `1~2'; to pick every third line starting with the second, `2~3'
+     would be used; to pick every fifth line starting with the tenth,
+     use `10~5'; and `50~0' is just an obscure way of saying `50'.
+
+`$'
+     This address matches the last line of the last file of input, or
+     the last line of each file when the `-i' or `-s' options are
+     specified.
+
+`/REGEXP/'
+     This will select any line which matches the regular expression
+     REGEXP.  If REGEXP itself includes any `/' characters, each must
+     be escaped by a backslash (`\').
+
+     The empty regular expression `//' repeats the last regular
+     expression match (the same holds if the empty regular expression is
+     passed to the `s' command).  Note that modifiers to regular
+     expressions are evaluated when the regular expression is compiled,
+     thus it is invalid to specify them together with the empty regular
+     expression.
+
+`\%REGEXP%'
+     (The `%' may be replaced by any other single character.)
+
+     This also matches the regular expression REGEXP, but allows one to
+     use a different delimiter than `/'.  This is particularly useful
+     if the REGEXP itself contains a lot of slashes, since it avoids
+     the tedious escaping of every `/'.  If REGEXP itself includes any
+     delimiter characters, each must be escaped by a backslash (`\').
+
+`/REGEXP/I'
+`\%REGEXP%I'
+     The `I' modifier to regular-expression matching is a GNU extension
+     which causes the REGEXP to be matched in a case-insensitive manner.
+
+`/REGEXP/M'
+`\%REGEXP%M'
+     The `M' modifier to regular-expression matching is a GNU `sed'
+     extension which directs GNU `sed' to match the regular expression
+     in `multi-line' mode.  The modifier causes `^' and `$' to match
+     respectively (in addition to the normal behavior) the empty string
+     after a newline, and the empty string before a newline.  There are
+     special character sequences (`\`' and `\'') which always match the
+     beginning or the end of the buffer.  In addition, the period
+     character does not match a new-line character in multi-line mode.
+
+
+   If no addresses are given, then all lines are matched; if one
+address is given, then only lines matching that address are matched.
+
+   An address range can be specified by specifying two addresses
+separated by a comma (`,').  An address range matches lines starting
+from where the first address matches, and continues until the second
+address matches (inclusively).
+
+   If the second address is a REGEXP, then checking for the ending
+match will start with the line _following_ the line which matched the
+first address: a range will always span at least two lines (except of
+course if the input stream ends).
+
+   If the second address is a NUMBER less than (or equal to) the line
+matching the first address, then only the one line is matched.
+
+   GNU `sed' also supports some special two-address forms; all these
+are GNU extensions:
+`0,/REGEXP/'
+     A line number of `0' can be used in an address specification like
+     `0,/REGEXP/' so that `sed' will try to match REGEXP in the first
+     input line too.  In other words, `0,/REGEXP/' is similar to
+     `1,/REGEXP/', except that if ADDR2 matches the very first line of
+     input the `0,/REGEXP/' form will consider it to end the range,
+     whereas the `1,/REGEXP/' form will match the beginning of its
+     range and hence make the range span up to the _second_ occurrence
+     of the regular expression.
+
+     Note that this is the only place where the `0' address makes
+     sense; there is no 0-th line and commands which are given the `0'
+     address in any other way will give an error.
+
+`ADDR1,+N'
+     Matches ADDR1 and the N lines following ADDR1.
+
+`ADDR1,~N'
+     Matches ADDR1 and the lines following ADDR1 until the next line
+     whose input line number is a multiple of N.
+
+   Appending the `!' character to the end of an address specification
+negates the sense of the match.  That is, if the `!' character follows
+an address range, then only lines which do _not_ match the address range
+will be selected.  This also works for singleton addresses, and,
+perhaps perversely, for the null address.

+
+3.3 Overview of Regular Expression Syntax
+=========================================
+
+To know how to use `sed', people should understand regular expressions
+("regexp" for short).  A regular expression is a pattern that is
+matched against a subject string from left to right.  Most characters
+are "ordinary": they stand for themselves in a pattern, and match the
+corresponding characters in the subject.  As a trivial example, the
+pattern
+
+     The quick brown fox
+
+matches a portion of a subject string that is identical to itself.  The
+power of regular expressions comes from the ability to include
+alternatives and repetitions in the pattern.  These are encoded in the
+pattern by the use of "special characters", which do not stand for
+themselves but instead are interpreted in some special way.  Here is a
+brief description of regular expression syntax as used in `sed'.
+
+`CHAR'
+     A single ordinary character matches itself.
+
+`*'
+     Matches a sequence of zero or more instances of matches for the
+     preceding regular expression, which must be an ordinary character,
+     a special character preceded by `\', a `.', a grouped regexp (see
+     below), or a bracket expression.  As a GNU extension, a postfixed
+     regular expression can also be followed by `*'; for example, `a**'
+     is equivalent to `a*'.  POSIX 1003.1-2001 says that `*' stands for
+     itself when it appears at the start of a regular expression or
+     subexpression, but many nonGNU implementations do not support this
+     and portable scripts should instead use `\*' in these contexts.
+
+`\+'
+     As `*', but matches one or more.  It is a GNU extension.
+
+`\?'
+     As `*', but only matches zero or one.  It is a GNU extension.
+
+`\{I\}'
+     As `*', but matches exactly I sequences (I is a decimal integer;
+     for portability, keep it between 0 and 255 inclusive).
+
+`\{I,J\}'
+     Matches between I and J, inclusive, sequences.
+
+`\{I,\}'
+     Matches more than or equal to I sequences.
+
+`\(REGEXP\)'
+     Groups the inner REGEXP as a whole, this is used to:
+
+        * Apply postfix operators, like `\(abcd\)*': this will search
+          for zero or more whole sequences of `abcd', while `abcd*'
+          would search for `abc' followed by zero or more occurrences
+          of `d'.  Note that support for `\(abcd\)*' is required by
+          POSIX 1003.1-2001, but many non-GNU implementations do not
+          support it and hence it is not universally portable.
+
+        * Use back references (see below).
+
+`.'
+     Matches any character, including newline.
+
+`^'
+     Matches the null string at beginning of the pattern space, i.e.
+     what appears after the circumflex must appear at the beginning of
+     the pattern space.
+
+     In most scripts, pattern space is initialized to the content of
+     each line (*note How `sed' works: Execution Cycle.).  So, it is a
+     useful simplification to think of `^#include' as matching only
+     lines where `#include' is the first thing on line--if there are
+     spaces before, for example, the match fails.  This simplification
+     is valid as long as the original content of pattern space is not
+     modified, for example with an `s' command.
+
+     `^' acts as a special character only at the beginning of the
+     regular expression or subexpression (that is, after `\(' or `\|').
+     Portable scripts should avoid `^' at the beginning of a
+     subexpression, though, as POSIX allows implementations that treat
+     `^' as an ordinary character in that context.
+
+`$'
+     It is the same as `^', but refers to end of pattern space.  `$'
+     also acts as a special character only at the end of the regular
+     expression or subexpression (that is, before `\)' or `\|'), and
+     its use at the end of a subexpression is not portable.
+
+`[LIST]'
+`[^LIST]'
+     Matches any single character in LIST: for example, `[aeiou]'
+     matches all vowels.  A list may include sequences like
+     `CHAR1-CHAR2', which matches any character between (inclusive)
+     CHAR1 and CHAR2.
+
+     A leading `^' reverses the meaning of LIST, so that it matches any
+     single character _not_ in LIST.  To include `]' in the list, make
+     it the first character (after the `^' if needed), to include `-'
+     in the list, make it the first or last; to include `^' put it
+     after the first character.
+
+     The characters `$', `*', `.', `[', and `\' are normally not
+     special within LIST.  For example, `[\*]' matches either `\' or
+     `*', because the `\' is not special here.  However, strings like
+     `[.ch.]', `[=a=]', and `[:space:]' are special within LIST and
+     represent collating symbols, equivalence classes, and character
+     classes, respectively, and `[' is therefore special within LIST
+     when it is followed by `.', `=', or `:'.  Also, when not in
+     `POSIXLY_CORRECT' mode, special escapes like `\n' and `\t' are
+     recognized within LIST.  *Note Escapes::.
+
+`REGEXP1\|REGEXP2'
+     Matches either REGEXP1 or REGEXP2.  Use parentheses to use complex
+     alternative regular expressions.  The matching process tries each
+     alternative in turn, from left to right, and the first one that
+     succeeds is used.  It is a GNU extension.
+
+`REGEXP1REGEXP2'
+     Matches the concatenation of REGEXP1 and REGEXP2.  Concatenation
+     binds more tightly than `\|', `^', and `$', but less tightly than
+     the other regular expression operators.
+
+`\DIGIT'
+     Matches the DIGIT-th `\(...\)' parenthesized subexpression in the
+     regular expression.  This is called a "back reference".
+     Subexpressions are implicity numbered by counting occurrences of
+     `\(' left-to-right.
+
+`\n'
+     Matches the newline character.
+
+`\CHAR'
+     Matches CHAR, where CHAR is one of `$', `*', `.', `[', `\', or `^'.
+     Note that the only C-like backslash sequences that you can
+     portably assume to be interpreted are `\n' and `\\'; in particular
+     `\t' is not portable, and matches a `t' under most implementations
+     of `sed', rather than a tab character.
+
+
+   Note that the regular expression matcher is greedy, i.e., matches
+are attempted from left to right and, if two or more matches are
+possible starting at the same character, it selects the longest.
+
+Examples:
+`abcdef'
+     Matches `abcdef'.
+
+`a*b'
+     Matches zero or more `a's followed by a single `b'.  For example,
+     `b' or `aaaaab'.
+
+`a\?b'
+     Matches `b' or `ab'.
+
+`a\+b\+'
+     Matches one or more `a's followed by one or more `b's: `ab' is the
+     shortest possible match, but other examples are `aaaab' or
+     `abbbbb' or `aaaaaabbbbbbb'.
+
+`.*'
+`.\+'
+     These two both match all the characters in a string; however, the
+     first matches every string (including the empty string), while the
+     second matches only strings containing at least one character.
+
+`^main.*(.*)'
+     This matches a string starting with `main', followed by an opening
+     and closing parenthesis.  The `n', `(' and `)' need not be
+     adjacent.
+
+`^#'
+     This matches a string beginning with `#'.
+
+`\\$'
+     This matches a string ending with a single backslash.  The regexp
+     contains two backslashes for escaping.
+
+`\$'
+     Instead, this matches a string consisting of a single dollar sign,
+     because it is escaped.
+
+`[a-zA-Z0-9]'
+     In the C locale, this matches any ASCII letters or digits.
+
+`[^ tab]\+'
+     (Here `tab' stands for a single tab character.)  This matches a
+     string of one or more characters, none of which is a space or a
+     tab.  Usually this means a word.
+
+`^\(.*\)\n\1$'
+     This matches a string consisting of two equal substrings separated
+     by a newline.
+
+`.\{9\}A$'
+     This matches nine characters followed by an `A'.
+
+`^.\{15\}A'
+     This matches the start of a string that contains 16 characters,
+     the last of which is an `A'.

+
+3.4 Often-Used Commands
+=======================
+
+If you use `sed' at all, you will quite likely want to know these
+commands.
+
+`#'
+     [No addresses allowed.]
+
+     The `#' character begins a comment; the comment continues until
+     the next newline.
+
+     If you are concerned about portability, be aware that some
+     implementations of `sed' (which are not POSIX conformant) may only
+     support a single one-line comment, and then only when the very
+     first character of the script is a `#'.
+
+     Warning: if the first two characters of the `sed' script are `#n',
+     then the `-n' (no-autoprint) option is forced.  If you want to put
+     a comment in the first line of your script and that comment begins
+     with the letter `n' and you do not want this behavior, then be
+     sure to either use a capital `N', or place at least one space
+     before the `n'.
+
+`q [EXIT-CODE]'
+     This command only accepts a single address.
+
+     Exit `sed' without processing any more commands or input.  Note
+     that the current pattern space is printed if auto-print is not
+     disabled with the `-n' options.  The ability to return an exit
+     code from the `sed' script is a GNU `sed' extension.
+
+`d'
+     Delete the pattern space; immediately start next cycle.
+
+`p'
+     Print out the pattern space (to the standard output).  This
+     command is usually only used in conjunction with the `-n'
+     command-line option.
+
+`n'
+     If auto-print is not disabled, print the pattern space, then,
+     regardless, replace the pattern space with the next line of input.
+     If there is no more input then `sed' exits without processing any
+     more commands.
+
+`{ COMMANDS }'
+     A group of commands may be enclosed between `{' and `}' characters.
+     This is particularly useful when you want a group of commands to
+     be triggered by a single address (or address-range) match.
+
+
+
+File: sed.info,  Node: The "s" Command,  Next: Other Commands,  Prev: Common Commands,  Up: sed Programs
+
+3.5 The `s' Command
+===================
+
+The syntax of the `s' (as in substitute) command is
+`s/REGEXP/REPLACEMENT/FLAGS'.  The `/' characters may be uniformly
+replaced by any other single character within any given `s' command.
+The `/' character (or whatever other character is used in its stead)
+can appear in the REGEXP or REPLACEMENT only if it is preceded by a `\'
+character.
+
+   The `s' command is probably the most important in `sed' and has a
+lot of different options.  Its basic concept is simple: the `s' command
+attempts to match the pattern space against the supplied REGEXP; if the
+match is successful, then that portion of the pattern space which was
+matched is replaced with REPLACEMENT.
+
+   The REPLACEMENT can contain `\N' (N being a number from 1 to 9,
+inclusive) references, which refer to the portion of the match which is
+contained between the Nth `\(' and its matching `\)'.  Also, the
+REPLACEMENT can contain unescaped `&' characters which reference the
+whole matched portion of the pattern space.  Finally, as a GNU `sed'
+extension, you can include a special sequence made of a backslash and
+one of the letters `L', `l', `U', `u', or `E'.  The meaning is as
+follows:
+
+`\L'
+     Turn the replacement to lowercase until a `\U' or `\E' is found,
+
+`\l'
+     Turn the next character to lowercase,
+
+`\U'
+     Turn the replacement to uppercase until a `\L' or `\E' is found,
+
+`\u'
+     Turn the next character to uppercase,
+
+`\E'
+     Stop case conversion started by `\L' or `\U'.
+
+   When the `g' flag is being used, case conversion does not propagate
+from one occurrence of the regular expression to another.  For example,
+when the following command is executed with `a-b-' in pattern space:
+     s/\(b\?\)-/x\u\1/g
+
+the output is `axxB'.  When replacing the first `-', the `\u' sequence
+only affects the empty replacement of `\1'.  It does not affect the `x'
+character that is added to pattern space when replacing `b-' with `xB'.
+
+   On the other hand, `\l' and `\u' do affect the remainder of the
+replacement text if they are followed by an empty substitution.  With
+`a-b-' in pattern space, the following command:
+     s/\(b\?\)-/\u\1x/g
+
+will replace `-' with `X' (uppercase) and `b-' with `Bx'.  If this
+behavior is undesirable, you can prevent it by adding a `\E'
+sequence--after `\1' in this case.
+
+   To include a literal `\', `&', or newline in the final replacement,
+be sure to precede the desired `\', `&', or newline in the REPLACEMENT
+with a `\'.
+
+   The `s' command can be followed by zero or more of the following
+FLAGS:
+
+`g'
+     Apply the replacement to _all_ matches to the REGEXP, not just the
+     first.
+
+`NUMBER'
+     Only replace the NUMBERth match of the REGEXP.
+
+     Note: the POSIX standard does not specify what should happen when
+     you mix the `g' and NUMBER modifiers, and currently there is no
+     widely agreed upon meaning across `sed' implementations.  For GNU
+     `sed', the interaction is defined to be: ignore matches before the
+     NUMBERth, and then match and replace all matches from the NUMBERth
+     on.
+
+`p'
+     If the substitution was made, then print the new pattern space.
+
+     Note: when both the `p' and `e' options are specified, the
+     relative ordering of the two produces very different results.  In
+     general, `ep' (evaluate then print) is what you want, but
+     operating the other way round can be useful for debugging.  For
+     this reason, the current version of GNU `sed' interprets specially
+     the presence of `p' options both before and after `e', printing
+     the pattern space before and after evaluation, while in general
+     flags for the `s' command show their effect just once.  This
+     behavior, although documented, might change in future versions.
+
+`w FILE-NAME'
+     If the substitution was made, then write out the result to the
+     named file.  As a GNU `sed' extension, two special values of
+     FILE-NAME are supported: `/dev/stderr', which writes the result to
+     the standard error, and `/dev/stdout', which writes to the standard
+     output.(1)
+
+`e'
+     This command allows one to pipe input from a shell command into
+     pattern space.  If a substitution was made, the command that is
+     found in pattern space is executed and pattern space is replaced
+     with its output.  A trailing newline is suppressed; results are
+     undefined if the command to be executed contains a NUL character.
+     This is a GNU `sed' extension.
+
+`I'
+`i'
+     The `I' modifier to regular-expression matching is a GNU extension
+     which makes `sed' match REGEXP in a case-insensitive manner.
+
+`M'
+`m'
+     The `M' modifier to regular-expression matching is a GNU `sed'
+     extension which directs GNU `sed' to match the regular expression
+     in `multi-line' mode.  The modifier causes `^' and `$' to match
+     respectively (in addition to the normal behavior) the empty string
+     after a newline, and the empty string before a newline.  There are
+     special character sequences (`\`' and `\'') which always match the
+     beginning or the end of the buffer.  In addition, the period
+     character does not match a new-line character in multi-line mode.
+
+
+   ---------- Footnotes ----------
+
+   (1) This is equivalent to `p' unless the `-i' option is being used.

+
+3.6 Less Frequently-Used Commands
+=================================
+
+Though perhaps less frequently used than those in the previous section,
+some very small yet useful `sed' scripts can be built with these
+commands.
+
+`y/SOURCE-CHARS/DEST-CHARS/'
+     (The `/' characters may be uniformly replaced by any other single
+     character within any given `y' command.)
+
+     Transliterate any characters in the pattern space which match any
+     of the SOURCE-CHARS with the corresponding character in DEST-CHARS.
+
+     Instances of the `/' (or whatever other character is used in its
+     stead), `\', or newlines can appear in the SOURCE-CHARS or
+     DEST-CHARS lists, provide that each instance is escaped by a `\'.
+     The SOURCE-CHARS and DEST-CHARS lists _must_ contain the same
+     number of characters (after de-escaping).
+
+`a\'
+`TEXT'
+     As a GNU extension, this command accepts two addresses.
+
+     Queue the lines of text which follow this command (each but the
+     last ending with a `\', which are removed from the output) to be
+     output at the end of the current cycle, or when the next input
+     line is read.
+
+     Escape sequences in TEXT are processed, so you should use `\\' in
+     TEXT to print a single backslash.
+
+     As a GNU extension, if between the `a' and the newline there is
+     other than a whitespace-`\' sequence, then the text of this line,
+     starting at the first non-whitespace character after the `a', is
+     taken as the first line of the TEXT block.  (This enables a
+     simplification in scripting a one-line add.)  This extension also
+     works with the `i' and `c' commands.
+
+`i\'
+`TEXT'
+     As a GNU extension, this command accepts two addresses.
+
+     Immediately output the lines of text which follow this command
+     (each but the last ending with a `\', which are removed from the
+     output).
+
+`c\'
+`TEXT'
+     Delete the lines matching the address or address-range, and output
+     the lines of text which follow this command (each but the last
+     ending with a `\', which are removed from the output) in place of
+     the last line (or in place of each line, if no addresses were
+     specified).  A new cycle is started after this command is done,
+     since the pattern space will have been deleted.
+
+`='
+     As a GNU extension, this command accepts two addresses.
+
+     Print out the current input line number (with a trailing newline).
+
+`l N'
+     Print the pattern space in an unambiguous form: non-printable
+     characters (and the `\' character) are printed in C-style escaped
+     form; long lines are split, with a trailing `\' character to
+     indicate the split; the end of each line is marked with a `$'.
+
+     N specifies the desired line-wrap length; a length of 0 (zero)
+     means to never wrap long lines.  If omitted, the default as
+     specified on the command line is used.  The N parameter is a GNU
+     `sed' extension.
+
+`r FILENAME'
+     As a GNU extension, this command accepts two addresses.
+
+     Queue the contents of FILENAME to be read and inserted into the
+     output stream at the end of the current cycle, or when the next
+     input line is read.  Note that if FILENAME cannot be read, it is
+     treated as if it were an empty file, without any error indication.
+
+     As a GNU `sed' extension, the special value `/dev/stdin' is
+     supported for the file name, which reads the contents of the
+     standard input.
+
+`w FILENAME'
+     Write the pattern space to FILENAME.  As a GNU `sed' extension,
+     two special values of FILE-NAME are supported: `/dev/stderr',
+     which writes the result to the standard error, and `/dev/stdout',
+     which writes to the standard output.(1)
+
+     The file will be created (or truncated) before the first input
+     line is read; all `w' commands (including instances of the `w' flag
+     on successful `s' commands) which refer to the same FILENAME are
+     output without closing and reopening the file.
+
+`D'
+     If pattern space contains no newline, start a normal new cycle as
+     if the `d' command was issued.  Otherwise, delete text in the
+     pattern space up to the first newline, and restart cycle with the
+     resultant pattern space, without reading a new line of input.
+
+`N'
+     Add a newline to the pattern space, then append the next line of
+     input to the pattern space.  If there is no more input then `sed'
+     exits without processing any more commands.
+
+`P'
+     Print out the portion of the pattern space up to the first newline.
+
+`h'
+     Replace the contents of the hold space with the contents of the
+     pattern space.
+
+`H'
+     Append a newline to the contents of the hold space, and then
+     append the contents of the pattern space to that of the hold space.
+
+`g'
+     Replace the contents of the pattern space with the contents of the
+     hold space.
+
+`G'
+     Append a newline to the contents of the pattern space, and then
+     append the contents of the hold space to that of the pattern space.
+
+`x'
+     Exchange the contents of the hold and pattern spaces.
+
+
+   ---------- Footnotes ----------
+
+   (1) This is equivalent to `p' unless the `-i' option is being used.

+3.7 Commands for `sed' gurus
+============================
+
+In most cases, use of these commands indicates that you are probably
+better off programming in something like `awk' or Perl.  But
+occasionally one is committed to sticking with `sed', and these
+commands can enable one to write quite convoluted scripts.
+
+`: LABEL'
+     [No addresses allowed.]
+
+     Specify the location of LABEL for branch commands.  In all other
+     respects, a no-op.
+
+`b LABEL'
+     Unconditionally branch to LABEL.  The LABEL may be omitted, in
+     which case the next cycle is started.
+
+`t LABEL'
+     Branch to LABEL only if there has been a successful `s'ubstitution
+     since the last input line was read or conditional branch was taken.
+     The LABEL may be omitted, in which case the next cycle is started.
+
+
+
+File: sed.info,  Node: Extended Commands,  Next: Escapes,  Prev: Programming Commands,  Up: sed Programs
+
+3.8 Commands Specific to GNU `sed'
+==================================
+
+These commands are specific to GNU `sed', so you must use them with
+care and only when you are sure that hindering portability is not evil.
+They allow you to check for GNU `sed' extensions or to do tasks that
+are required quite often, yet are unsupported by standard `sed's.
+
+`e [COMMAND]'
+     This command allows one to pipe input from a shell command into
+     pattern space.  Without parameters, the `e' command executes the
+     command that is found in pattern space and replaces the pattern
+     space with the output; a trailing newline is suppressed.
+
+     If a parameter is specified, instead, the `e' command interprets
+     it as a command and sends its output to the output stream.  The
+     command can run across multiple lines, all but the last ending with
+     a back-slash.
+
+     In both cases, the results are undefined if the command to be
+     executed contains a NUL character.
+
+     Note that, unlike the `r' command, the output of the command will
+     be printed immediately; the `r' command instead delays the output
+     to the end of the current cycle.
+
+`F'
+     Print out the file name of the current input file (with a trailing
+     newline).
+
+`L N'
+     This GNU `sed' extension fills and joins lines in pattern space to
+     produce output lines of (at most) N characters, like `fmt' does;
+     if N is omitted, the default as specified on the command line is
+     used.  This command is considered a failed experiment and unless
+     there is enough request (which seems unlikely) will be removed in
+     future versions.
+
+`Q [EXIT-CODE]'
+     This command only accepts a single address.
+
+     This command is the same as `q', but will not print the contents
+     of pattern space.  Like `q', it provides the ability to return an
+     exit code to the caller.
+
+     This command can be useful because the only alternative ways to
+     accomplish this apparently trivial function are to use the `-n'
+     option (which can unnecessarily complicate your script) or
+     resorting to the following snippet, which wastes time by reading
+     the whole file without any visible effect:
+
+          :eat
+          $d       Quit silently on the last line
+          N        Read another line, silently
+          g        Overwrite pattern space each time to save memory
+          b eat
+
+`R FILENAME'
+     Queue a line of FILENAME to be read and inserted into the output
+     stream at the end of the current cycle, or when the next input
+     line is read.  Note that if FILENAME cannot be read, or if its end
+     is reached, no line is appended, without any error indication.
+
+     As with the `r' command, the special value `/dev/stdin' is
+     supported for the file name, which reads a line from the standard
+     input.
+
+`T LABEL'
+     Branch to LABEL only if there have been no successful
+     `s'ubstitutions since the last input line was read or conditional
+     branch was taken. The LABEL may be omitted, in which case the next
+     cycle is started.
+
+`v VERSION'
+     This command does nothing, but makes `sed' fail if GNU `sed'
+     extensions are not supported, simply because other versions of
+     `sed' do not implement it.  In addition, you can specify the
+     version of `sed' that your script requires, such as `4.0.5'.  The
+     default is `4.0' because that is the first version that
+     implemented this command.
+
+     This command enables all GNU extensions even if `POSIXLY_CORRECT'
+     is set in the environment.
+
+`W FILENAME'
+     Write to the given filename the portion of the pattern space up to
+     the first newline.  Everything said under the `w' command about
+     file handling holds here too.
+
+`z'
+     This command empties the content of pattern space.  It is usually
+     the same as `s/.*//', but is more efficient and works in the
+     presence of invalid multibyte sequences in the input stream.
+     POSIX mandates that such sequences are _not_ matched by `.', so
+     that there is no portable way to clear `sed''s buffers in the
+     middle of the script in most multibyte locales (including UTF-8
+     locales).

+
+3.9 GNU Extensions for Escapes in Regular Expressions
+=====================================================
+
+Until this chapter, we have only encountered escapes of the form `\^',
+which tell `sed' not to interpret the circumflex as a special
+character, but rather to take it literally.  For example, `\*' matches
+a single asterisk rather than zero or more backslashes.
+
+   This chapter introduces another kind of escape(1)--that is, escapes
+that are applied to a character or sequence of characters that
+ordinarily are taken literally, and that `sed' replaces with a special
+character.  This provides a way of encoding non-printable characters in
+patterns in a visible manner.  There is no restriction on the
+appearance of non-printing characters in a `sed' script but when a
+script is being prepared in the shell or by text editing, it is usually
+easier to use one of the following escape sequences than the binary
+character it represents:
+
+   The list of these escapes is:
+
+`\a'
+     Produces or matches a BEL character, that is an "alert" (ASCII 7).
+
+`\f'
+     Produces or matches a form feed (ASCII 12).
+
+`\n'
+     Produces or matches a newline (ASCII 10).
+
+`\r'
+     Produces or matches a carriage return (ASCII 13).
+
+`\t'
+     Produces or matches a horizontal tab (ASCII 9).
+
+`\v'
+     Produces or matches a so called "vertical tab" (ASCII 11).
+
+`\cX'
+     Produces or matches `CONTROL-X', where X is any character.  The
+     precise effect of `\cX' is as follows: if X is a lower case
+     letter, it is converted to upper case.  Then bit 6 of the
+     character (hex 40) is inverted.  Thus `\cz' becomes hex 1A, but
+     `\c{' becomes hex 3B, while `\c;' becomes hex 7B.
+
+`\dXXX'
+     Produces or matches a character whose decimal ASCII value is XXX.
+
+`\oXXX'
+     Produces or matches a character whose octal ASCII value is XXX.
+
+`\xXX'
+     Produces or matches a character whose hexadecimal ASCII value is
+     XX.
+
+   `\b' (backspace) was omitted because of the conflict with the
+existing "word boundary" meaning.
+
+   Other escapes match a particular character class and are valid only
+in regular expressions:
+
+`\w'
+     Matches any "word" character.  A "word" character is any letter or
+     digit or the underscore character.
+
+`\W'
+     Matches any "non-word" character.
+
+`\b'
+     Matches a word boundary; that is it matches if the character to
+     the left is a "word" character and the character to the right is a
+     "non-word" character, or vice-versa.
+
+`\B'
+     Matches everywhere but on a word boundary; that is it matches if
+     the character to the left and the character to the right are
+     either both "word" characters or both "non-word" characters.
+
+`\`'
+     Matches only at the start of pattern space.  This is different
+     from `^' in multi-line mode.
+
+`\''
+     Matches only at the end of pattern space.  This is different from
+     `$' in multi-line mode.
+
+
+   ---------- Footnotes ----------
+
+   (1) All the escapes introduced here are GNU extensions, with the
+exception of `\n'.  In basic regular expression mode, setting
+`POSIXLY_CORRECT' disables them inside bracket expressions.

+
+4.1 Centering Lines
+===================
+
+This script centers all lines of a file on a 80 columns width.  To
+change that width, the number in `\{...\}' must be replaced, and the
+number of added spaces also must be changed.
+
+   Note how the buffer commands are used to separate parts in the
+regular expressions to be matched--this is a common technique.
+
+     #!/usr/bin/sed -f
+
+     # Put 80 spaces in the buffer
+     1 {
+       x
+       s/^$/          /
+       s/^.*$/&&&&&&&&/
+       x
+     }
+
+     # del leading and trailing spaces
+     y/tab/ /
+     s/^ *//
+     s/ *$//
+
+     # add a newline and 80 spaces to end of line
+     G
+
+     # keep first 81 chars (80 + a newline)
+     s/^\(.\{81\}\).*$/\1/
+
+     # \2 matches half of the spaces, which are moved to the beginning
+     s/^\(.*\)\n\(.*\)\2/\2\1/

+
+4.2 Increment a Number
+======================
+
+This script is one of a few that demonstrate how to do arithmetic in
+`sed'.  This is indeed possible,(1) but must be done manually.
+
+   To increment one number you just add 1 to last digit, replacing it
+by the following digit.  There is one exception: when the digit is a
+nine the previous digits must be also incremented until you don't have
+a nine.
+
+   This solution by Bruno Haible is very clever and smart because it
+uses a single buffer; if you don't have this limitation, the algorithm
+used in *note Numbering lines: cat -n, is faster.  It works by
+replacing trailing nines with an underscore, then using multiple `s'
+commands to increment the last digit, and then again substituting
+underscores with zeros.
+
+     #!/usr/bin/sed -f
+
+     /[^0-9]/ d
+
+     # replace all trailing 9s by _ (any other character except digits, could
+     # be used)
+     :d
+     s/9\(_*\)$/_\1/
+     td
+
+     # incr last digit only.  The first line adds a most-significant
+     # digit of 1 if we have to add a digit.
+
+     s/^\(_*\)$/1\1/; tn
+     s/8\(_*\)$/9\1/; tn
+     s/7\(_*\)$/8\1/; tn
+     s/6\(_*\)$/7\1/; tn
+     s/5\(_*\)$/6\1/; tn

+
+4.3 Rename Files to Lower Case
+==============================
+
+This is a pretty strange use of `sed'.  We transform text, and
+transform it to be shell commands, then just feed them to shell.  Don't
+worry, even worse hacks are done when using `sed'; I have seen a script
+converting the output of `date' into a `bc' program!
+
+   The main body of this is the `sed' script, which remaps the name
+from lower to upper (or vice-versa) and even checks out if the remapped
+name is the same as the original name.  Note how the script is
+parameterized using shell variables and proper quoting.
+
+     #! /bin/sh
+     # rename files to lower/upper case...
+     #
+     # usage:
+     #    move-to-lower *
+     #    move-to-upper *
+     # or
+     #    move-to-lower -R .
+     #    move-to-upper -R .
+     #

+4.4 Print `bash' Environment
+============================
+
+This script strips the definition of the shell functions from the
+output of the `set' Bourne-shell command.
+
+     #!/bin/sh
+
+     set | sed -n '
+     :x
+
+     # if no occurrence of "=()" print and load next line
+     /=()/! { p; b; }
+     / () $/! { p; b; }
+
+     # possible start of functions section
+     # save the line in case this is a var like FOO="() "
+     h
+
+     # if the next line has a brace, we quit because
+     # nothing comes after functions
+     n
+     /^{/ q
+
+     # print the old line
+     x; p
+
+     # work on the new line now
+     x; bx
+     '
+
+
+File: sed.info,  Node: Reverse chars of lines,  Next: tac,  Prev: Print bash environment,  Up: Examples
+
+4.5 Reverse Characters of Lines
+===============================
+
+This script can be used to reverse the position of characters in lines.
+The technique moves two characters at a time, hence it is faster than
+more intuitive implementations.
+
+   Note the `tx' command before the definition of the label.  This is
+often needed to reset the flag that is tested by the `t' command.
+
+   Imaginative readers will find uses for this script.  An example is
+reversing the output of `banner'.(1)
+
+     #!/usr/bin/sed -f
+
+     /../! b
+
+     # Reverse a line.  Begin embedding the line between two newlines
+     s/^.*$/\
+     &\
+     /
+
+     # Move first character at the end.  The regexp matches until
+     # there are zero or one characters between the markers
+     tx
+     :x
+     s/\(\n.\)\(.*\)\(.\n\)/\3\2\1/
+     tx
+
+     # Remove the newline markers
+     s/\n//g
+
+   ---------- Footnotes ----------
+
+   (1) This requires another script to pad the output of banner; for
+example
+
+     #! /bin/sh
+
+     banner -w $1 $2 $3 $4 |
+       sed -e :a -e '/^.\{0,'$1'\}$/ { s/$/ /; ba; }' |
+       ~/sedscripts/reverseline.sed

+
+4.6 Reverse Lines of Files
+==========================
+
+This one begins a series of totally useless (yet interesting) scripts
+emulating various Unix commands.  This, in particular, is a `tac'
+workalike.
+
+   Note that on implementations other than GNU `sed' this script might
+easily overflow internal buffers.
+
+     #!/usr/bin/sed -nf
+
+     # reverse all lines of input, i.e. first line became last, ...
+
+     # from the second line, the buffer (which contains all previous lines)
+     # is *appended* to current line, so, the order will be reversed
+     1! G
+
+     # on the last line we're done -- print everything
+     $ p
+
+     # store everything on the buffer again
+     h
+
+
+File: sed.info,  Node: cat -n,  Next: cat -b,  Prev: tac,  Up: Examples
+
+4.7 Numbering Lines
+===================
+
+This script replaces `cat -n'; in fact it formats its output exactly
+like GNU `cat' does.
+
+   Of course this is completely useless and for two reasons:  first,
+because somebody else did it in C, second, because the following
+Bourne-shell script could be used for the same purpose and would be
+much faster:
+
+     #! /bin/sh
+     sed -e "=" $@ | sed -e '
+       s/^/      /
+       N
+       s/^ *\(......\)\n/\1  /
+     '
+
+   It uses `sed' to print the line number, then groups lines two by two
+using `N'.  Of course, this script does not teach as much as the one
+presented below.
+
+   The algorithm used for incrementing uses both buffers, so the line
+is printed as soon as possible and then discarded.  The number is split
+so that changing digits go in a buffer and unchanged ones go in the
+other; the changed digits are modified in a single step (using a `y'
+command).  The line number for the next line is then composed and
+stored in the hold space, to be used in the next iteration.
+
+     #!/usr/bin/sed -nf
+
+     # Prime the pump on the first line
+     x
+     /^$/ s/^.*$/1/

+     # Add the correct line number before the pattern
+     G
+     h

+     s/^ *\(......\)\n/\1  /p

+     # if we're going to add a digit on the next line

+4.8 Numbering Non-blank Lines
+=============================
+
+Emulating `cat -b' is almost the same as `cat -n'--we only have to
+select which lines are to be numbered and which are not.
+
+   The part that is common to this script and the previous one is not
+commented to show how important it is to comment `sed' scripts
+properly...
+
+     #!/usr/bin/sed -nf
+
+     /^$/ {
+       p
+       b
+     }
+
+     # Same as cat -n from now

+     /^9*$/ s/^/0/
+     s/.9*$/x&/

+
+4.9 Counting Characters
+=======================
+
+This script shows another way to do arithmetic with `sed'.  In this
+case we have to add possibly large numbers, so implementing this by
+successive increments would not be feasible (and possibly even more
+complicated to contrive than this script).
+
+   The approach is to map numbers to letters, kind of an abacus
+implemented with `sed'.  `a's are units, `b's are tens and so on: we
+simply add the number of characters on the current line as units, and
+then propagate the carry to tens, hundreds, and so on.
+
+   As usual, running totals are kept in hold space.
+
+   On the last line, we convert the abacus form back to decimal.  For
+the sake of variety, this is done with a loop rather than with some 80
+`s' commands(1): first we convert units, removing `a's from the number;
+then we rotate letters so that tens become `a's, and so on until no
+more letters remain.
+
+     #!/usr/bin/sed -nf
+
+     # Add n+1 a's to hold space (+1 is for the newline)
+     s/./a/g
+     H
+     x
+     s/\n/a/
+
+     # Do the carry.  The t's and b's are not necessary,
+     # but they do speed up the thing
+     t a
+     : a;  s/aaaaaaaaaa/b/g; t b; b done
+     : b;  s/bbbbbbbbbb/c/g; t c; b done

+
+4.10 Counting Words
+===================
+
+This script is almost the same as the previous one, once each of the
+words on the line is converted to a single `a' (in the previous script
+each letter was changed to an `a').
+
+   It is interesting that real `wc' programs have optimized loops for
+`wc -c', so they are much slower at counting words rather than
+characters.  This script's bottleneck, instead, is arithmetic, and
+hence the word-counting one is faster (it has to manage smaller
+numbers).
+
+   Again, the common parts are not commented to show the importance of
+commenting `sed' scripts.
+
+     #!/usr/bin/sed -nf

+the first 10 lines of input; the number of displayed lines is right
+before the `q' command.
+
+     #!/usr/bin/sed -f
+     10q
+

+
+4.13 Printing the Last Lines
+============================
+
+Printing the last N lines rather than the first is more complex but
+indeed possible.  N is encoded in the second line, before the bang
+character.
+
+   This script is similar to the `tac' script in that it keeps the
+final output in the hold space and prints it at the end:
+
+     #!/usr/bin/sed -nf
+
+     1! {; H; g; }
+     1,10 !s/[^\n]*\n//
+     $p
+     h
+
+   Mainly, the scripts keeps a window of 10 lines and slides it by
+adding a line and deleting the oldest (the substitution command on the
+second line works like a `D' command but does not restart the loop).
+
+   The "sliding window" technique is a very powerful way to write
+efficient and complex `sed' scripts, because commands like `P' would
+require a lot of work if implemented manually.
+
+   To introduce the technique, which is fully demonstrated in the rest
+of this chapter and is based on the `N', `P' and `D' commands, here is
+an implementation of `tail' using a simple "sliding window."
+
+   This looks complicated but in fact the working is the same as the
+last script: after we have kicked in the appropriate number of lines,
+however, we stop using the hold space to keep inter-line state, and
+instead use `N' and `D' to slide pattern space by one line:
+
+     #!/usr/bin/sed -f
+
+     1h
+     2,10 {; H; g; }
+     $q
+     1,9d
+     N
+     D
+
+   Note how the first, second and fourth line are inactive after the
+first ten lines of input.  After that, all the script does is: exiting
+on the last line of input, appending the next input line to pattern
+space, and removing the first line.

+
+4.14 Make Duplicate Lines Unique
+================================
+
+This is an example of the art of using the `N', `P' and `D' commands,
+probably the most difficult to master.
+
+     #!/usr/bin/sed -f
+     h
+
+     :b
+     # On the last line, print and exit
+     $b
+     N
+     /^\(.*\)\n\1$/ {
+         # The two lines are identical.  Undo the effect of
+         # the n command.
+         g
+         bb
+     }
+
+     # If the `N' command had added the last line, print and exit
+     $b
+
+     # The lines are different; print the first and go
+     # back working on the second.
+     P
+     D
+
+   As you can see, we mantain a 2-line window using `P' and `D'.  This
+technique is often used in advanced `sed' scripts.

+
+4.15 Print Duplicated Lines of Input
+====================================
+
+This script prints only duplicated lines, like `uniq -d'.
+
+     #!/usr/bin/sed -nf
+
+     $b
+     N
+     /^\(.*\)\n\1$/ {
+         # Print the first of the duplicated lines
+         s/.*\n//
+         p
+
+         # Loop until we get a different line
+         :b
+         $b
+         N
+         /^\(.*\)\n\1$/ {
+             s/.*\n//
+             bb
+         }
+     }
+
+     # The last line cannot be followed by duplicates
+     $b
+
+     # Found a different one.  Leave it alone in the pattern space
+     # and go back to the top, hunting its duplicates
+     D

+
+File: sed.info,  Node: uniq -u,  Next: cat -s,  Prev: uniq -d,  Up: Examples
+
+4.16 Remove All Duplicated Lines
+================================
+
+This script prints only unique lines, like `uniq -u'.
+
+     #!/usr/bin/sed -f
+
+     # Search for a duplicate line --- until that, print what you find.
+     $b

+
+4.17 Squeezing Blank Lines
+==========================
+
+As a final example, here are three scripts, of increasing complexity
+and speed, that implement the same function as `cat -s', that is
+squeezing blank lines.
+
+   The first leaves a blank line at the beginning and end if there are
+some already.
+
+     #!/usr/bin/sed -f
+
+     # on empty lines, join with next
+     # Note there is a star in the regexp
+     :x
+     /^\n*$/ {
+     N
+     bx
+     }
+
+     # now, squeeze all '\n', this can be also done by:
+     # s/^\(\n\)*/\1/
+     s/\n*/\
+     /
+
+   This one is a bit more complex and removes all empty lines at the
+beginning.  It does leave a single blank line at end if one was there.
+
+     #!/usr/bin/sed -f
+
+     # delete all leading empty lines
+     1,/^./{
+     /./!d
+     }
+
+     # on an empty line we remove it and all the following
+     # empty lines, but one
+     :x
+     /./!{
+     N
+     s/^\n$//
+     tx
+     }
+
+   This removes leading and trailing blank lines.  It is also the
+fastest.  Note that loops are completely done with `n' and `b', without
+relying on `sed' to restart the the script automatically at the end of
+a line.
+
+     #!/usr/bin/sed -nf
+
+     # delete all (leading) blanks
+     /./!d
+
+     # get here: so there is a non empty
+     :x
+     # print it
+     p
+     # get next
+     n
+     # got chars? print it again, etc...
+     /./bx
+
+     # no, don't have chars: got an empty line
+     :z
+     # get next, if last line we finish here so no trailing
+     # empty lines are written
+     n
+     # also empty? then ignore it, and get next... this will
+     # remove ALL empty lines
+     /./!bz
+
+     # all empty lines were deleted/ignored, but we have a non empty.  As
+     # what we want to do is to squeeze, insert a blank line artificially

+5 GNU `sed''s Limitations and Non-limitations
+*********************************************
+
+For those who want to write portable `sed' scripts, be aware that some
+implementations have been known to limit line lengths (for the pattern
+and hold spaces) to be no more than 4000 bytes.  The POSIX standard
+specifies that conforming `sed' implementations shall support at least
+8192 byte line lengths.  GNU `sed' has no built-in limit on line length;
+as long as it can `malloc()' more (virtual) memory, you can feed or
+construct lines as long as you like.
+
+   However, recursion is used to handle subpatterns and indefinite
+repetition.  This means that the available stack space may limit the
+size of the buffer that can be processed by certain patterns.

+7 Reporting Bugs
+****************
+
+Email bug reports to <bug-sed@gnu.org>.  Also, please include the
+output of `sed --version' in the body of your report if at all possible.
+
+   Please do not send a bug report like this:
+
+     while building frobme-1.3.4
+     $ configure
+     error--> sed: file sedscr line 1: Unknown option to 's'
+
+   If GNU `sed' doesn't configure your favorite package, take a few
+extra minutes to identify the specific problem and make a stand-alone
+test case.  Unlike other programs such as C compilers, making such test
+cases for `sed' is quite simple.
+
+   A stand-alone test case includes all the data necessary to perform
+the test, and the specific invocation of `sed' that causes the problem.
+The smaller a stand-alone test case is, the better.  A test case should
+not involve something as far removed from `sed' as "try to configure
+frobme-1.3.4".  Yes, that is in principle enough information to look
+for the bug, but that is not a very practical prospect.
+
+   Here are a few commonly reported bugs that are not bugs.
+
+`N' command on the last line
+     Most versions of `sed' exit without printing anything when the `N'
+     command is issued on the last line of a file.  GNU `sed' prints
+     pattern space before exiting unless of course the `-n' command
+     switch has been specified.  This choice is by design.
+
+     For example, the behavior of
+          sed N foo bar
+     would depend on whether foo has an even or an odd number of
+     lines(1).  Or, when writing a script to read the next few lines
+     following a pattern match, traditional implementations of `sed'
+     would force you to write something like
+          /foo/{ $!N; $!N; $!N; $!N; $!N; $!N; $!N; $!N; $!N }
+     instead of just
+          /foo/{ N;N;N;N;N;N;N;N;N; }
+
+     In any case, the simplest workaround is to use `$d;N' in scripts
+     that rely on the traditional behavior, or to set the
+     `POSIXLY_CORRECT' variable to a non-empty value.
+
+Regex syntax clashes (problems with backslashes)
+     `sed' uses the POSIX basic regular expression syntax.  According to
+     the standard, the meaning of some escape sequences is undefined in
+     this syntax;  notable in the case of `sed' are `\|', `\+', `\?',
+     `\`', `\'', `\<', `\>', `\b', `\B', `\w', and `\W'.
+
+     As in all GNU programs that use POSIX basic regular expressions,
+     `sed' interprets these escape sequences as special characters.
+     So, `x\+' matches one or more occurrences of `x'.  `abc\|def'
+     matches either `abc' or `def'.
+
+     This syntax may cause problems when running scripts written for
+     other `sed's.  Some `sed' programs have been written with the
+     assumption that `\|' and `\+' match the literal characters `|' and
+     `+'.  Such scripts must be modified by removing the spurious
+     backslashes if they are to be used with modern implementations of
+     `sed', like GNU `sed'.
+
+     On the other hand, some scripts use s|abc\|def||g to remove
+     occurrences of _either_ `abc' or `def'.  While this worked until
+     `sed' 4.0.x, newer versions interpret this as removing the string
+     `abc|def'.  This is again undefined behavior according to POSIX,
+     and this interpretation is arguably more robust: older `sed's, for
+     example, required that the regex matcher parsed `\/' as `/' in the
+     common case of escaping a slash, which is again undefined
+     behavior; the new behavior avoids this, and this is good because
+     the regex matcher is only partially under our control.
+
+     In addition, this version of `sed' supports several escape
+     characters (some of which are multi-character) to insert
+     non-printable characters in scripts (`\a', `\c', `\d', `\o', `\r',
+     `\t', `\v', `\x').  These can cause similar problems with scripts
+     written for other `sed's.
+
+`-i' clobbers read-only files
+     In short, `sed -i' will let you delete the contents of a read-only
+     file, and in general the `-i' option (*note Invocation: Invoking
+     sed.) lets you clobber protected files.  This is not a bug, but
+     rather a consequence of how the Unix filesystem works.
+
+     The permissions on a file say what can happen to the data in that
+     file, while the permissions on a directory say what can happen to
+     the list of files in that directory.  `sed -i' will not ever open
+     for writing  a file that is already on disk.  Rather, it will work
+     on a temporary file that is finally renamed to the original name:
+     if you rename or delete files, you're actually modifying the
+     contents of the directory, so the operation depends on the
+     permissions of the directory, not of the file.  For this same
+     reason, `sed' does not let you use `-i' on a writeable file in a
+     read-only directory, and will break hard or symbolic links when
+     `-i' is used on such a file.
+
+`0a' does not work (gives an error)
+     There is no line 0.  0 is a special address that is only used to
+     treat addresses like `0,/RE/' as active when the script starts: if
+     you write `1,/abc/d' and the first line includes the word `abc',
+     then that match would be ignored because address ranges must span
+     at least two lines (barring the end of the file); but what you
+     probably wanted is to delete every line up to the first one
+     including `abc', and this is obtained with `0,/abc/d'.
+
+`[a-z]' is case insensitive
+     You are encountering problems with locales.  POSIX mandates that
+     `[a-z]' uses the current locale's collation order - in C parlance,
+     that means using `strcoll(3)' instead of `strcmp(3)'.  Some
+     locales have a case-insensitive collation order, others don't.
+
+     Another problem is that `[a-z]' tries to use collation symbols.
+     This only happens if you are on the GNU system, using GNU libc's
+     regular expression matcher instead of compiling the one supplied
+     with GNU sed.  In a Danish locale, for example, the regular
+     expression `^[a-z]$' matches the string `aa', because this is a
+     single collating symbol that comes after `a' and before `b'; `ll'
+     behaves similarly in Spanish locales, or `ij' in Dutch locales.
+
+     To work around these problems, which may cause bugs in shell
+     scripts, set the `LC_COLLATE' and `LC_CTYPE' environment variables
+     to `C'.
+
+`s/.*//' does not clear pattern space
+     This happens if your input stream includes invalid multibyte
+     sequences.  POSIX mandates that such sequences are _not_ matched
+     by `.', so that `s/.*//' will not clear pattern space as you would
+     expect.  In fact, there is no way to clear sed's buffers in the
+     middle of the script in most multibyte locales (including UTF-8
+     locales).  For this reason, GNU `sed' provides a `z' command (for
+     `zap') as an extension.
+
+     To work around these problems, which may cause bugs in shell
+     scripts, set the `LC_COLLATE' and `LC_CTYPE' environment variables
+     to `C'.

+Appendix A Extended regular expressions
+***************************************
+
+The only difference between basic and extended regular expressions is in
+the behavior of a few characters: `?', `+', parentheses, braces (`{}'),
+and `|'.  While basic regular expressions require these to be escaped
+if you want them to behave as special characters, when using extended
+regular expressions you must escape them if you want them _to match a
+literal character_.  `|' is special here because `\|' is a GNU
+extension - standard basic regular expressions do not provide its
+functionality.
+
+Examples:
+`abc?'
+     becomes `abc\?' when using extended regular expressions.  It
+     matches the literal string `abc?'.
+
+`c\+'
+     becomes `c+' when using extended regular expressions.  It matches
+     one or more `c's.
+
+`a\{3,\}'
+     becomes `a{3,}' when using extended regular expressions.  It
+     matches three or more `a's.
+
+`\(abc\)\{2,3\}'
+     becomes `(abc){2,3}' when using extended regular expressions.  It
+     matches either `abcabc' or `abcabcabc'.
+
+`\(abc*\)\1'
+     becomes `(abc*)\1' when using extended regular expressions.
+     Backreferences must still be escaped when using extended regular
+     expressions.

+@node Introduction
+@chapter Introduction
+
+@cindex Stream editor
+@command{sed} is a stream editor.
+A stream editor is used to perform basic text
+transformations on an input stream
+(a file or input from a pipeline).
+While in some ways similar to an editor which
+permits scripted edits (such as @command{ed}),
+@command{sed} works by making only one pass over the
+input(s), and is consequently more efficient.
+But it is @command{sed}'s ability to filter text in a pipeline
+which particularly distinguishes it from other types of
+editors.
+
+
+@node Invoking sed
+@chapter Invocation
+
+Normally @command{sed} is invoked like this:
+
+@example
+sed SCRIPT INPUTFILE...
+@end example
+
+The full format for invoking @command{sed} is:
+
+@example
+sed OPTIONS... [SCRIPT] [INPUTFILE...]
+@end example
+
+If you do not specify @var{INPUTFILE}, or if @var{INPUTFILE} is @file{-},
+@command{sed} filters the contents of the standard input.  The @var{script}
+is actually the first non-option parameter, which @command{sed} specially
+considers a script and not an input file if (and only if) none of the
+other @var{options} specifies a script to be executed, that is if neither
+of the @option{-e} and @option{-f} options is specified.
+
+@command{sed} may be invoked with the following command-line options:
+
+@table @code
+@item --version
+@opindex --version
+@cindex Version, printing
+Print out the version of @command{sed} that is being run and a copyright notice,
+then exit.
+
+@item --help
+@opindex --help
+@cindex Usage summary, printing
+Print a usage message briefly summarizing these command-line options
+and the bug-reporting address,
+then exit.
+
+@item -n
+@itemx --quiet
+@itemx --silent
+@opindex -n
+@opindex --quiet
+@opindex --silent
+@cindex Disabling autoprint, from command line
+By default, @command{sed} prints out the pattern space
+at the end of each cycle through the script (@pxref{Execution Cycle, ,
+How @code{sed} works}).
+These options disable this automatic printing,
+and @command{sed} only produces output when explicitly told to
+via the @code{p} command.
+
+@item -e @var{script}
+@itemx --expression=@var{script}
+@opindex -e
+@opindex --expression
+@cindex Script, from command line
+Add the commands in @var{script} to the set of commands to be
+run while processing the input.
+
+@item -f @var{script-file}
+@itemx --file=@var{script-file}
+@opindex -f
+@opindex --file
+@cindex Script, from a file
+Add the commands contained in the file @var{script-file}
+to the set of commands to be run while processing the input.
+
+@item -i[@var{SUFFIX}]
+@itemx --in-place[=@var{SUFFIX}]
+@opindex -i
+@opindex --in-place
+@cindex In-place editing, activating
+@cindex @value{SSEDEXT}, in-place editing
+This option specifies that files are to be edited in-place.
+@value{SSED} does this by creating a temporary file and
+sending output to this file rather than to the standard
+output.@footnote{This applies to commands such as @code{=},
+@code{a}, @code{c}, @code{i}, @code{l}, @code{p}.  You can
+still write to the standard output by using the @code{w}
+@cindex @value{SSEDEXT}, @file{/dev/stdout} file
+or @code{W} commands together with the @file{/dev/stdout}
+special file}.
+
+This option implies @option{-s}.
+
+When the end of the file is reached, the temporary file is
+renamed to the output file's original name.  The extension,
+if supplied, is used to modify the name of the old file
+before renaming the temporary file, thereby making a backup
+copy@footnote{Note that @value{SSED} creates the backup
+file whether or not any output is actually changed.}).
+
+@cindex In-place editing, Perl-style backup file names
+This rule is followed: if the extension doesn't contain a @code{*},
+then it is appended to the end of the current filename as a
+suffix; if the extension does contain one or more @code{*}
+characters, then @emph{each} asterisk is replaced with the
+current filename.  This allows you to add a prefix to the
+backup file, instead of (or in addition to) a suffix, or
+even to place backup copies of the original files into another
+directory (provided the directory already exists).
+
+If no extension is supplied, the original file is
+overwritten without making a backup.
+
+@item -l @var{N}
+@itemx --line-length=@var{N}
+@opindex -l
+@opindex --line-length
+@cindex Line length, setting
+Specify the default line-wrap length for the @code{l} command.
+A length of 0 (zero) means to never wrap long lines.  If
+not specified, it is taken to be 70.
+
+@item --posix
+@opindex --posix
+@cindex @value{SSEDEXT}, disabling
+@value{SSED} includes several extensions to @acronym{POSIX}
+sed.  In order to simplify writing portable scripts, this
+option disables all the extensions that this manual documents,
+including additional commands.
+@cindex @code{POSIXLY_CORRECT} behavior, enabling
+Most of the extensions accept @command{sed} programs that
+are outside the syntax mandated by @acronym{POSIX}, but some
+of them (such as the behavior of the @command{N} command
+described in @pxref{Reporting Bugs}) actually violate the
+standard.  If you want to disable only the latter kind of
+extension, you can set the @code{POSIXLY_CORRECT} variable
+to a non-empty value.
+
+@item -b
+@itemx --binary
+@opindex -b
+@opindex --binary
+This option is available on every platform, but is only effective where the
+operating system makes a distinction between text files and binary files.
+When such a distinction is made---as is the case for MS-DOS, Windows,
+Cygwin---text files are composed of lines separated by a carriage return
+@emph{and} a line feed character, and @command{sed} does not see the
+ending CR.  When this option is specified, @command{sed} will open
+input files in binary mode, thus not requesting this special processing
+and considering lines to end at a line feed.
+
+@item --follow-symlinks
+@opindex --follow-symlinks
+This option is available only on platforms that support
+symbolic links and has an effect only if option @option{-i}
+is specified.  In this case, if the file that is specified
+on the command line is a symbolic link, @command{sed} will
+follow the link and edit the ultimate destination of the
+link.  The default behavior is to break the symbolic link,
+so that the link destination will not be modified.
+
+@item -r
+@itemx --regexp-extended
+@opindex -r
+@opindex --regexp-extended
+@cindex Extended regular expressions, choosing
+@cindex @acronym{GNU} extensions, extended regular expressions
+Use extended regular expressions rather than basic
+regular expressions.  Extended regexps are those that
+@command{egrep} accepts; they can be clearer because they
+usually have less backslashes, but are a @acronym{GNU} extension
+and hence scripts that use them are not portable.
+@xref{Extended regexps, , Extended regular expressions}.
+
+@ifset PERL
+@item -R
+@itemx --regexp-perl
+@opindex -R
+@opindex --regexp-perl
+@cindex Perl-style regular expressions, choosing
+@cindex @value{SSEDEXT}, Perl-style regular expressions
+Use Perl-style regular expressions rather than basic
+regular expressions.  Perl-style regexps are extremely
+powerful but are a @value{SSED} extension and hence scripts that
+use it are not portable.  @xref{Perl regexps, ,
+Perl-style regular expressions}.
+@end ifset
+
+@item -s
+@itemx --separate
+@opindex -s
+@opindex --separate
+@cindex Working on separate files
+By default, @command{sed} will consider the files specified on the
+command line as a single continuous long stream.  This @value{SSED}
+extension allows the user to consider them as separate files:
+range addresses (such as @samp{/abc/,/def/}) are not allowed
+to span several files, line numbers are relative to the start
+of each file, @code{$} refers to the last line of each file,
+and files invoked from the @code{R} commands are rewound at the
+start of each file.
+
+@item -u
+@itemx --unbuffered
+@opindex -u
+@opindex --unbuffered
+@cindex Unbuffered I/O, choosing
+Buffer both input and output as minimally as practical.
+(This is particularly useful if the input is coming from
+the likes of @samp{tail -f}, and you wish to see the transformed
+output as soon as possible.)
+
+@item -z
+@itemx --null-data
+@itemx --zero-terminated
+@opindex -z
+@opindex --null-data
+@opindex --zero-terminated
+Treat the input as a set of lines, each terminated by a zero byte
+(the ASCII @samp{NUL} character) instead of a newline.  This option can
+be used with commands like @samp{sort -z} and @samp{find -print0}
+to process arbitrary file names.
+@end table
+
+If no @option{-e}, @option{-f}, @option{--expression}, or @option{--file}
+options are given on the command-line,
+then the first non-option argument on the command line is
+taken to be the @var{script} to be executed.
+
+@cindex Files to be processed as input
+If any command-line parameters remain after processing the above,
+these parameters are interpreted as the names of input files to
+be processed.
+@cindex Standard input, processing as input
+A file name of @samp{-} refers to the standard input stream.
+The standard input will be processed if no file names are specified.

+
+@cindex @command{sed} program structure
+@cindex Script structure
+A @command{sed} program consists of one or more @command{sed} commands,
+passed in by one or more of the
+@option{-e}, @option{-f}, @option{--expression}, and @option{--file}
+options, or the first non-option argument if zero of these
+options are used.
+This document will refer to ``the'' @command{sed} script;
+this is understood to mean the in-order catenation
+of all of the @var{script}s and @var{script-file}s passed in.
+
+Commands within a @var{script} or @var{script-file} can be
+separated by semicolons (@code{;}) or newlines (ASCII 10).
+Some commands, due to their syntax, cannot be followed by semicolons
+working as command separators and thus should be terminated
+with newlines or be placed at the end of a @var{script} or @var{script-file}.
+Commands can also be preceded with optional non-significant
+whitespace characters.
+
+Each @code{sed} command consists of an optional address or
+address range, followed by a one-character command name
+and any additional command-specific code.

+
+@cindex Buffer spaces, pattern and hold
+@cindex Spaces, pattern and hold
+@cindex Pattern space, definition
+@cindex Hold space, definition
+@command{sed} maintains two data buffers: the active @emph{pattern} space,
+and the auxiliary @emph{hold} space. Both are initially empty.
+
+@command{sed} operates by performing the following cycle on each
+line of input: first, @command{sed} reads one line from the input
+stream, removes any trailing newline, and places it in the pattern space.
+Then commands are executed; each command can have an address associated
+to it: addresses are a kind of condition code, and a command is only
+executed if the condition is verified before the command is to be
+executed.
+
+When the end of the script is reached, unless the @option{-n} option
+is in use, the contents of pattern space are printed out to the output
+stream, adding back the trailing newline if it was removed.@footnote{Actually,
+if @command{sed} prints a line without the terminating newline, it will
+nevertheless print the missing newline as soon as more text is sent to
+the same output stream, which gives the ``least expected surprise''
+even though it does not make commands like @samp{sed -n p} exactly
+identical to @command{cat}.} Then the next cycle starts for the next
+input line.
+
+Unless special commands (like @samp{D}) are used, the pattern space is
+deleted between two cycles. The hold space, on the other hand, keeps
+its data between cycles (see commands @samp{h}, @samp{H}, @samp{x},
+@samp{g}, @samp{G} to move data between both buffers).

+@cindex Addresses, in @command{sed} scripts
+@cindex Line selection
+@cindex Selecting lines to process
+
+Addresses in a @command{sed} script can be in any of the following forms:
+@table @code
+@item @var{number}
+@cindex Address, numeric
+@cindex Line, selecting by number
+Specifying a line number will match only that line in the input.
+(Note that @command{sed} counts lines continuously across all input files
+unless @option{-i} or @option{-s} options are specified.)
+
+@item @var{first}~@var{step}
+@cindex @acronym{GNU} extensions, @samp{@var{n}~@var{m}} addresses
+This @acronym{GNU} extension matches every @var{step}th line
+starting with line @var{first}.
+In particular, lines will be selected when there exists
+a non-negative @var{n} such that the current line-number equals
+@var{first} + (@var{n} * @var{step}).
+Thus, to select the odd-numbered lines,
+one would use @code{1~2};
+to pick every third line starting with the second, @samp{2~3} would be used;
+to pick every fifth line starting with the tenth, use @samp{10~5};
+and @samp{50~0} is just an obscure way of saying @code{50}.
+
+@item $
+@cindex Address, last line
+@cindex Last line, selecting
+@cindex Line, selecting last
+This address matches the last line of the last file of input, or
+the last line of each file when the @option{-i} or @option{-s} options
+are specified.
+
+@item /@var{regexp}/
+@cindex Address, as a regular expression
+@cindex Line, selecting by regular expression match
+This will select any line which matches the regular expression @var{regexp}.
+If @var{regexp} itself includes any @code{/} characters,
+each must be escaped by a backslash (@code{\}).
+
+@cindex empty regular expression
+@cindex @value{SSEDEXT}, modifiers and the empty regular expression
+The empty regular expression @samp{//} repeats the last regular
+expression match (the same holds if the empty regular expression is
+passed to the @code{s} command).  Note that modifiers to regular expressions
+are evaluated when the regular expression is compiled, thus it is invalid to
+specify them together with the empty regular expression.
+
+@item \%@var{regexp}%
+(The @code{%} may be replaced by any other single character.)
+
+@cindex Slash character, in regular expressions
+This also matches the regular expression @var{regexp},
+but allows one to use a different delimiter than @code{/}.
+This is particularly useful if the @var{regexp} itself contains
+a lot of slashes, since it avoids the tedious escaping of every @code{/}.
+If @var{regexp} itself includes any delimiter characters,
+each must be escaped by a backslash (@code{\}).
+
+@item /@var{regexp}/I
+@itemx \%@var{regexp}%I
+@cindex @acronym{GNU} extensions, @code{I} modifier
+@ifset PERL
+@cindex Perl-style regular expressions, case-insensitive
+@end ifset
+The @code{I} modifier to regular-expression matching is a @acronym{GNU}
+extension which causes the @var{regexp} to be matched in
+a case-insensitive manner.
+
+@item /@var{regexp}/M
+@itemx \%@var{regexp}%M
+@cindex @value{SSEDEXT}, @code{M} modifier
+@ifset PERL
+@cindex Perl-style regular expressions, multiline
+@end ifset
+The @code{M} modifier to regular-expression matching is a @value{SSED}
+extension which directs @value{SSED} to match the regular expression
+in @cite{multi-line} mode.  The modifier causes @code{^} and @code{$} to
+match respectively (in addition to the normal behavior) the empty string
+after a newline, and the empty string before a newline.  There are
+special character sequences
+@ifset PERL
+(@code{\A} and @code{\Z} in Perl mode, @code{\`} and @code{\'}
+in basic or extended regular expression modes)
+@end ifset
+@ifclear PERL
+(@code{\`} and @code{\'})
+@end ifclear
+which always match the beginning or the end of the buffer.
+In addition,
+@ifset PERL
+just like in Perl mode without the @code{S} modifier,
+@end ifset
+the period character does not match a new-line character in
+multi-line mode.
+
+@ifset PERL
+@item /@var{regexp}/S
+@itemx \%@var{regexp}%S
+@cindex @value{SSEDEXT}, @code{S} modifier
+@cindex Perl-style regular expressions, single line
+The @code{S} modifier to regular-expression matching is only valid
+in Perl mode and specifies that the dot character (@code{.}) will
+match the newline character too.  @code{S} stands for @cite{single-line}.
+@end ifset
+
+@ifset PERL
+@item /@var{regexp}/X
+@itemx \%@var{regexp}%X
+@cindex @value{SSEDEXT}, @code{X} modifier
+@cindex Perl-style regular expressions, extended
+The @code{X} modifier to regular-expression matching is also
+valid in Perl mode only.  If it is used, whitespace in the
+pattern (other than in a character class) and
+characters between a @kbd{#} outside a character class and the
+next newline character are ignored. An escaping backslash
+can be used to include a whitespace or @kbd{#} character as part
+of the pattern.
+@end ifset
+@end table
+
+If no addresses are given, then all lines are matched;
+if one address is given, then only lines matching that
+address are matched.
+
+@cindex Range of lines
+@cindex Several lines, selecting
+An address range can be specified by specifying two addresses
+separated by a comma (@code{,}).  An address range matches lines
+starting from where the first address matches, and continues
+until the second address matches (inclusively).
+
+If the second address is a @var{regexp}, then checking for the
+ending match will start with the line @emph{following} the
+line which matched the first address: a range will always
+span at least two lines (except of course if the input stream
+ends).
+
+If the second address is a @var{number} less than (or equal to)
+the line matching the first address, then only the one line is
+matched.
+
+@cindex Special addressing forms
+@cindex Range with start address of zero
+@cindex Zero, as range start address
+@cindex @var{addr1},+N
+@cindex @var{addr1},~N
+@cindex @acronym{GNU} extensions, special two-address forms
+@cindex @acronym{GNU} extensions, @code{0} address
+@cindex @acronym{GNU} extensions, 0,@var{addr2} addressing
+@cindex @acronym{GNU} extensions, @var{addr1},+@var{N} addressing
+@cindex @acronym{GNU} extensions, @var{addr1},~@var{N} addressing
+@value{SSED} also supports some special two-address forms; all these
+are @acronym{GNU} extensions:
+@table @code
+@item 0,/@var{regexp}/
+A line number of @code{0} can be used in an address specification like
+@code{0,/@var{regexp}/} so that @command{sed} will try to match
+@var{regexp} in the first input line too.  In other words,
+@code{0,/@var{regexp}/} is similar to @code{1,/@var{regexp}/},
+except that if @var{addr2} matches the very first line of input the
+@code{0,/@var{regexp}/} form will consider it to end the range, whereas
+the @code{1,/@var{regexp}/} form will match the beginning of its range and
+hence make the range span up to the @emph{second} occurrence of the
+regular expression.
+
+Note that this is the only place where the @code{0} address makes
+sense; there is no 0-th line and commands which are given the @code{0}
+address in any other way will give an error.
+
+@item @var{addr1},+@var{N}
+Matches @var{addr1} and the @var{N} lines following @var{addr1}.
+
+@item @var{addr1},~@var{N}
+Matches @var{addr1} and the lines following @var{addr1}
+until the next line whose input line number is a multiple of @var{N}.
+@end table
+
+@cindex Excluding lines
+@cindex Selecting non-matching lines
+Appending the @code{!} character to the end of an address
+specification negates the sense of the match.
+That is, if the @code{!} character follows an address range,
+then only lines which do @emph{not} match the address range
+will be selected.
+This also works for singleton addresses,
+and, perhaps perversely, for the null address.
+
+
+@node Regular Expressions
+@section Overview of Regular Expression Syntax
+
+To know how to use @command{sed}, people should understand regular
+expressions (@dfn{regexp} for short).  A regular expression
+is a pattern that is matched against a
+subject string from left to right.  Most characters are
+@dfn{ordinary}: they stand for
+themselves in a pattern, and match the corresponding characters
+in the subject.  As a trivial example, the pattern
+
+@example
+The quick brown fox
+@end example
+
+@noindent
+matches a portion of a subject string that is identical to
+itself.  The power of regular expressions comes from the
+ability to include alternatives and repetitions in the pattern.
+These are encoded in the pattern by the use of @dfn{special characters},
+which do not stand for themselves but instead
+are interpreted in some special way.  Here is a brief description
+of regular expression syntax as used in @command{sed}.
+
+@table @code
+@item @var{char}
+A single ordinary character matches itself.
+
+@item *
+@cindex @acronym{GNU} extensions, to basic regular expressions
+Matches a sequence of zero or more instances of matches for the
+preceding regular expression, which must be an ordinary character, a
+special character preceded by @code{\}, a @code{.}, a grouped regexp
+(see below), or a bracket expression.  As a @acronym{GNU} extension, a
+postfixed regular expression can also be followed by @code{*}; for
+example, @code{a**} is equivalent to @code{a*}.  @acronym{POSIX}
+1003.1-2001 says that @code{*} stands for itself when it appears at
+the start of a regular expression or subexpression, but many
+non@acronym{GNU} implementations do not support this and portable
+scripts should instead use @code{\*} in these contexts.
+
+@item \+
+@cindex @acronym{GNU} extensions, to basic regular expressions
+As @code{*}, but matches one or more.  It is a @acronym{GNU} extension.
+
+@item \?
+@cindex @acronym{GNU} extensions, to basic regular expressions
+As @code{*}, but only matches zero or one.  It is a @acronym{GNU} extension.
+
+@item \@{@var{i}\@}
+As @code{*}, but matches exactly @var{i} sequences (@var{i} is a
+decimal integer; for portability, keep it between 0 and 255
+inclusive).
+
+@item \@{@var{i},@var{j}\@}
+Matches between @var{i} and @var{j}, inclusive, sequences.
+
+@item \@{@var{i},\@}
+Matches more than or equal to @var{i} sequences.
+
+@item \(@var{regexp}\)
+Groups the inner @var{regexp} as a whole, this is used to: 
+
+@itemize @bullet
+@item
+@cindex @acronym{GNU} extensions, to basic regular expressions
+Apply postfix operators, like @code{\(abcd\)*}:
+this will search for zero or more whole sequences 
+of @samp{abcd}, while @code{abcd*} would search
+for @samp{abc} followed by zero or more occurrences
+of @samp{d}.  Note that support for @code{\(abcd\)*} is
+required by @acronym{POSIX} 1003.1-2001, but many non-@acronym{GNU}
+implementations do not support it and hence it is not universally
+portable.         
+
+@item
+Use back references (see below).
+@end itemize
+
+@item .
+Matches any character, including newline.
+
+@item ^
+Matches the null string at beginning of the pattern space, i.e. what
+appears after the circumflex must appear at the beginning of the
+pattern space.
+
+In most scripts, pattern space is initialized to the content of each
+line (@pxref{Execution Cycle, , How @code{sed} works}).  So, it is a
+useful simplification to think of @code{^#include} as matching only
+lines where @samp{#include} is the first thing on line---if there are
+spaces before, for example, the match fails.  This simplification is
+valid as long as the original content of pattern space is not modified,
+for example with an @code{s} command.
+
+@code{^} acts as a special character only at the beginning of the
+regular expression or subexpression (that is, after @code{\(} or
+@code{\|}).  Portable scripts should avoid @code{^} at the beginning of
+a subexpression, though, as @acronym{POSIX} allows implementations that
+treat @code{^} as an ordinary character in that context.
+
+@item $
+It is the same as @code{^}, but refers to end of pattern space.
+@code{$} also acts as a special character only at the end
+of the regular expression or subexpression (that is, before @code{\)}
+or @code{\|}), and its use at the end of a subexpression is not
+portable.
+
+
+@item [@var{list}]
+@itemx [^@var{list}]
+Matches any single character in @var{list}: for example,
+@code{[aeiou]} matches all vowels.  A list may include
+sequences like @code{@var{char1}-@var{char2}}, which
+matches any character between (inclusive) @var{char1}
+and @var{char2}.
+
+A leading @code{^} reverses the meaning of @var{list}, so that
+it matches any single character @emph{not} in @var{list}.  To include
+@code{]} in the list, make it the first character (after
+the @code{^} if needed), to include @code{-} in the list,
+make it the first or last; to include @code{^} put
+it after the first character.
+
+@cindex @code{POSIXLY_CORRECT} behavior, bracket expressions
+The characters @code{$}, @code{*}, @code{.}, @code{[}, and @code{\}
+are normally not special within @var{list}.  For example, @code{[\*]}
+matches either @samp{\} or @samp{*}, because the @code{\} is not
+special here.  However, strings like @code{[.ch.]}, @code{[=a=]}, and
+@code{[:space:]} are special within @var{list} and represent collating
+symbols, equivalence classes, and character classes, respectively, and
+@code{[} is therefore special within @var{list} when it is followed by
+@code{.}, @code{=}, or @code{:}.  Also, when not in
+@env{POSIXLY_CORRECT} mode, special escapes like @code{\n} and
+@code{\t} are recognized within @var{list}.  @xref{Escapes}.
+
+@item @var{regexp1}\|@var{regexp2}
+@cindex @acronym{GNU} extensions, to basic regular expressions
+Matches either @var{regexp1} or @var{regexp2}.  Use
+parentheses to use complex alternative regular expressions.
+The matching process tries each alternative in turn, from
+left to right, and the first one that succeeds is used.
+It is a @acronym{GNU} extension.
+
+@item @var{regexp1}@var{regexp2}
+Matches the concatenation of @var{regexp1} and @var{regexp2}.
+Concatenation binds more tightly than @code{\|}, @code{^}, and
+@code{$}, but less tightly than the other regular expression
+operators.
+
+@item \@var{digit}
+Matches the @var{digit}-th @code{\(@dots{}\)} parenthesized
+subexpression in the regular expression.  This is called a @dfn{back
+reference}.  Subexpressions are implicity numbered by counting
+occurrences of @code{\(} left-to-right.
+
+@item \n
+Matches the newline character.
+
+@item \@var{char}
+Matches @var{char}, where @var{char} is one of @code{$},
+@code{*}, @code{.}, @code{[}, @code{\}, or @code{^}.
+Note that the only C-like
+backslash sequences that you can portably assume to be
+interpreted are @code{\n} and @code{\\}; in particular
+@code{\t} is not portable, and matches a @samp{t} under most
+implementations of @command{sed}, rather than a tab character.
+
+@end table
+
+@cindex Greedy regular expression matching
+Note that the regular expression matcher is greedy, i.e., matches
+are attempted from left to right and, if two or more matches are
+possible starting at the same character, it selects the longest.
+
+@noindent
+Examples:
+@table @samp
+@item abcdef
+Matches @samp{abcdef}.
+
+@item a*b
+Matches zero or more @samp{a}s followed by a single
+@samp{b}.  For example, @samp{b} or @samp{aaaaab}. 
+
+@item a\?b
+Matches @samp{b} or @samp{ab}.
+
+@item a\+b\+
+Matches one or more @samp{a}s followed by one or more
+@samp{b}s: @samp{ab} is the shortest possible match, but
+other examples are @samp{aaaab} or @samp{abbbbb} or
+@samp{aaaaaabbbbbbb}.
+
+@item .*
+@itemx .\+
+These two both match all the characters in a string;
+however, the first matches every string (including the empty
+string), while the second matches only strings containing
+at least one character.
+
+@item ^main.*(.*)
+This matches a string starting with @samp{main},
+followed by an opening and closing
+parenthesis.  The @samp{n}, @samp{(} and @samp{)} need not
+be adjacent.
+
+@item ^#
+This matches a string beginning with @samp{#}.
+
+@item \\$
+This matches a string ending with a single backslash.  The
+regexp contains two backslashes for escaping.
+
+@item \$
+Instead, this matches a string consisting of a single dollar sign,
+because it is escaped.
+
+@item [a-zA-Z0-9]
+In the C locale, this matches any @acronym{ASCII} letters or digits.
+
+@item [^ @kbd{tab}]\+
+(Here @kbd{tab} stands for a single tab character.)
+This matches a string of one or more
+characters, none of which is a space or a tab.
+Usually this means a word.
+
+@item ^\(.*\)\n\1$
+This matches a string consisting of two equal substrings separated by
+a newline.
+
+@item .\@{9\@}A$
+This matches nine characters followed by an @samp{A}.
+
+@item ^.\@{15\@}A
+This matches the start of a string that contains 16 characters,
+the last of which is an @samp{A}.

+@cindex Comments, in scripts
+The @code{#} character begins a comment;
+the comment continues until the next newline.
+
+@cindex Portability, comments
+If you are concerned about portability, be aware that
+some implementations of @command{sed} (which are not @sc{posix}

+and then only when the very first character of the script is a @code{#}.
+
+@findex -n, forcing from within a script
+@cindex Caveat --- #n on first line
+Warning: if the first two characters of the @command{sed} script
+are @code{#n}, then the @option{-n} (no-autoprint) option is forced.
+If you want to put a comment in the first line of your script
+and that comment begins with the letter @samp{n}
+and you do not want this behavior,
+then be sure to either use a capital @samp{N},

+
+@end table
+
+@node The "s" Command
+@section The @code{s} Command
+
+The syntax of the @code{s} (as in substitute) command is
+@samp{s/@var{regexp}/@var{replacement}/@var{flags}}.  The @code{/}
+characters may be uniformly replaced by any other single
+character within any given @code{s} command.  The @code{/}
+character (or whatever other character is used in its stead)
+can appear in the @var{regexp} or @var{replacement}
+only if it is preceded by a @code{\} character.
+
+The @code{s} command is probably the most important in @command{sed}
+and has a lot of different options.  Its basic concept is simple:
+the @code{s} command attempts to match the pattern
+space against the supplied @var{regexp}; if the match is
+successful, then that portion of the pattern
+space which was matched is replaced with @var{replacement}.
+
+@cindex Backreferences, in regular expressions
+@cindex Parenthesized substrings
+The @var{replacement} can contain @code{\@var{n}} (@var{n} being
+a number from 1 to 9, inclusive) references, which refer to
+the portion of the match which is contained between the @var{n}th
+@code{\(} and its matching @code{\)}.
+Also, the @var{replacement} can contain unescaped @code{&}
+characters which reference the whole matched portion
+of the pattern space.
+@cindex @value{SSEDEXT}, case modifiers in @code{s} commands
+Finally, as a @value{SSED} extension, you can include a
+special sequence made of a backslash and one of the letters
+@code{L}, @code{l}, @code{U}, @code{u}, or @code{E}.
+The meaning is as follows:
+
+@table @code
+@item \L
+Turn the replacement
+to lowercase until a @code{\U} or @code{\E} is found,
+
+@item \l
+Turn the
+next character to lowercase,
+
+@item \U
+Turn the replacement to uppercase
+until a @code{\L} or @code{\E} is found,
+
+@item \u
+Turn the next character
+to uppercase,
+
+@item \E
+Stop case conversion started by @code{\L} or @code{\U}.
+@end table
+
+When the @code{g} flag is being used, case conversion does not
+propagate from one occurrence of the regular expression to
+another.  For example, when the following command is executed
+with @samp{a-b-} in pattern space:
+@example
+s/\(b\?\)-/x\u\1/g
+@end example
+
+@noindent
+the output is @samp{axxB}.  When replacing the first @samp{-},
+the @samp{\u} sequence only affects the empty replacement of
+@samp{\1}.  It does not affect the @code{x} character that is
+added to pattern space when replacing @code{b-} with @code{xB}.
+
+On the other hand, @code{\l} and @code{\u} do affect the remainder
+of the replacement text if they are followed by an empty substitution.
+With @samp{a-b-} in pattern space, the following command:
+@example
+s/\(b\?\)-/\u\1x/g
+@end example
+
+@noindent
+will replace @samp{-} with @samp{X} (uppercase) and @samp{b-} with
+@samp{Bx}.  If this behavior is undesirable, you can prevent it by
+adding a @samp{\E} sequence---after @samp{\1} in this case.
+
+To include a literal @code{\}, @code{&}, or newline in the final
+replacement, be sure to precede the desired @code{\}, @code{&},
+or newline in the @var{replacement} with a @code{\}.
+
+@findex s command, option flags
+@cindex Substitution of text, options
+The @code{s} command can be followed by zero or more of the
+following @var{flags}:
+
+@table @code
+@item g
+@cindex Global substitution
+@cindex Replacing all text matching regexp in a line
+Apply the replacement to @emph{all} matches to the @var{regexp},

+
+@cindex @acronym{GNU} extensions, @code{g} and @var{number} modifier interaction in @code{s} command
+@cindex Mixing @code{g} and @var{number} modifiers in the @code{s} command
+Note: the @sc{posix} standard does not specify what should happen
+when you mix the @code{g} and @var{number} modifiers,
+and currently there is no widely agreed upon meaning
+across @command{sed} implementations.
+For @value{SSED}, the interaction is defined to be:
+ignore matches before the @var{number}th,
+and then match and replace all matches from
+the @var{number}th on.
+
+@item p
+@cindex Text, printing after substitution
+If the substitution was made, then print the new pattern space.
+
+Note: when both the @code{p} and @code{e} options are specified,
+the relative ordering of the two produces very different results.
+In general, @code{ep} (evaluate then print) is what you want,
+but operating the other way round can be useful for debugging.
+For this reason, the current version of @value{SSED} interprets
+specially the presence of @code{p} options both before and after
+@code{e}, printing the pattern space before and after evaluation,
+while in general flags for the @code{s} command show their
+effect just once.  This behavior, although documented, might
+change in future versions.
+
+@item w @var{file-name}
+@cindex Text, writing to a file after substitution
+@cindex @value{SSEDEXT}, @file{/dev/stdout} file
+@cindex @value{SSEDEXT}, @file{/dev/stderr} file
+If the substitution was made, then write out the result to the named file.
+As a @value{SSED} extension, two special values of @var{file-name} are
+supported: @file{/dev/stderr}, which writes the result to the standard
+error, and @file{/dev/stdout}, which writes to the standard
+output.@footnote{This is equivalent to @code{p} unless the @option{-i}
+option is being used.}

+@item e
+@cindex Evaluate Bourne-shell commands, after substitution
+@cindex Subprocesses
+@cindex @value{SSEDEXT}, evaluating Bourne-shell commands
+@cindex @value{SSEDEXT}, subprocesses
+This command allows one to pipe input from a shell command
+into pattern space.  If a substitution was made, the command
+that is found in pattern space is executed and pattern space
+is replaced with its output.  A trailing newline is suppressed;
+results are undefined if the command to be executed contains
+a @sc{nul} character.  This is a @value{SSED} extension.

+@cindex Perl-style regular expressions, case-insensitive
+@end ifset
+The @code{I} modifier to regular-expression matching is a @acronym{GNU}

+
+@item M
+@itemx m
+@cindex @value{SSEDEXT}, @code{M} modifier
+@ifset PERL
+@cindex Perl-style regular expressions, multiline
+@end ifset
+The @code{M} modifier to regular-expression matching is a @value{SSED}
+extension which directs @value{SSED} to match the regular expression
+in @cite{multi-line} mode.  The modifier causes @code{^} and @code{$} to
+match respectively (in addition to the normal behavior) the empty string
+after a newline, and the empty string before a newline.  There are
+special character sequences
+@ifset PERL
+(@code{\A} and @code{\Z} in Perl mode, @code{\`} and @code{\'}
+in basic or extended regular expression modes)
+@end ifset
+@ifclear PERL
+(@code{\`} and @code{\'})
+@end ifclear
+which always match the beginning or the end of the buffer.
+In addition,
+@ifset PERL
+just like in Perl mode without the @code{S} modifier,
+@end ifset
+the period character does not match a new-line character in
+multi-line mode.
+
+@ifset PERL
+@item S
+@itemx s
+@cindex @value{SSEDEXT}, @code{S} modifier
+@cindex Perl-style regular expressions, single line
+The @code{S} modifier to regular-expression matching is only valid

+match the newline character too.  @code{S} stands for @cite{single-line}.
+@end ifset

+@item X
+@itemx x
+@cindex @value{SSEDEXT}, @code{X} modifier
+@cindex Perl-style regular expressions, extended

+valid in Perl mode only.  If it is used, whitespace in the
+pattern (other than in a character class) and
+characters between a @kbd{#} outside a character class and the
+next newline character are ignored. An escaping backslash
+can be used to include a whitespace or @kbd{#} character as part
+of the pattern.

+these commands.
+
+@table @code
+@item y/@var{source-chars}/@var{dest-chars}/
+(The @code{/} characters may be uniformly replaced by
+any other single character within any given @code{y} command.)
+
+@findex y (transliterate) command
+@cindex Transliteration
+Transliterate any characters in the pattern space which match
+any of the @var{source-chars} with the corresponding character
+in @var{dest-chars}.
+
+Instances of the @code{/} (or whatever other character is used in its stead),
+@code{\}, or newlines can appear in the @var{source-chars} or @var{dest-chars}
+lists, provide that each instance is escaped by a @code{\}.
+The @var{source-chars} and @var{dest-chars} lists @emph{must}
+contain the same number of characters (after de-escaping).
+
+@item a\
+@itemx @var{text}
+@cindex @value{SSEDEXT}, two addresses supported by most commands
+As a @acronym{GNU} extension, this command accepts two addresses.
+
+@findex a (append text lines) command
+@cindex Appending text after a line
+@cindex Text, appending
+Queue the lines of text which follow this command
+(each but the last ending with a @code{\},
+which are removed from the output)
+to be output at the end of the current cycle,
+or when the next input line is read.
+
+Escape sequences in @var{text} are processed, so you should
+use @code{\\} in @var{text} to print a single backslash.
+
+As a @acronym{GNU} extension, if between the @code{a} and the newline there is
+other than a whitespace-@code{\} sequence, then the text of this line,
+starting at the first non-whitespace character after the @code{a},
+is taken as the first line of the @var{text} block.
+(This enables a simplification in scripting a one-line add.)
+This extension also works with the @code{i} and @code{c} commands.
+
+@item i\
+@itemx @var{text}
+@cindex @value{SSEDEXT}, two addresses supported by most commands
+As a @acronym{GNU} extension, this command accepts two addresses.

+
+@item c\
+@itemx @var{text}
+@findex c (change to text lines) command
+@cindex Replacing selected lines with other text
+Delete the lines matching the address or address-range,
+and output the lines of text which follow this command
+(each but the last ending with a @code{\},
+which are removed from the output)
+in place of the last line
+(or in place of each line, if no addresses were specified).
+A new cycle is started after this command is done,
+since the pattern space will have been deleted.

+@item =
+@cindex @value{SSEDEXT}, two addresses supported by most commands
+As a @acronym{GNU} extension, this command accepts two addresses.
+
+@findex = (print line number) command

+@item l @var{n}
+@findex l (list unambiguously) command
+@cindex List pattern space
+@cindex Printing text unambiguously
+@cindex Line length, setting
+@cindex @value{SSEDEXT}, setting line length
+Print the pattern space in an unambiguous form:
+non-printable characters (and the @code{\} character)
+are printed in C-style escaped form; long lines are split,
+with a trailing @code{\} character to indicate the split;
+the end of each line is marked with a @code{$}.
+
+@var{n} specifies the desired line-wrap length;
+a length of 0 (zero) means to never wrap long lines.  If omitted,
+the default as specified on the command line is used.  The @var{n}
+parameter is a @value{SSED} extension.
+
+@item r @var{filename}
+@cindex @value{SSEDEXT}, two addresses supported by most commands
+As a @acronym{GNU} extension, this command accepts two addresses.
+
+@findex r (read file) command
+@cindex Read text from a file
+@cindex @value{SSEDEXT}, @file{/dev/stdin} file
+Queue the contents of @var{filename} to be read and
+inserted into the output stream at the end of the current cycle,
+or when the next input line is read.
+Note that if @var{filename} cannot be read, it is treated as
+if it were an empty file, without any error indication.
+
+As a @value{SSED} extension, the special value @file{/dev/stdin}
+is supported for the file name, which reads the contents of the
+standard input.
+
+@item w @var{filename}
+@findex w (write file) command
+@cindex Write to a file
+@cindex @value{SSEDEXT}, @file{/dev/stdout} file
+@cindex @value{SSEDEXT}, @file{/dev/stderr} file
+Write the pattern space to @var{filename}.
+As a @value{SSED} extension, two special values of @var{file-name} are
+supported: @file{/dev/stderr}, which writes the result to the standard
+error, and @file{/dev/stdout}, which writes to the standard
+output.@footnote{This is equivalent to @code{p} unless the @option{-i}
+option is being used.}
+
+The file will be created (or truncated) before the first input line is
+read; all @code{w} commands (including instances of the @code{w} flag
+on successful @code{s} commands) which refer to the same @var{filename}
+are output without closing and reopening the file.
+
+@item D
+@findex D (delete first line) command
+@cindex Delete first line from pattern space
+If pattern space contains no newline, start a normal new cycle as if
+the @code{d} command was issued.  Otherwise, delete text in the pattern
+space up to the first newline, and restart cycle with the resultant
+pattern space, without reading a new line of input.
+
+@item N
+@findex N (append Next line) command
+@cindex Next input line, append to pattern space
+@cindex Append next input line to pattern space
+Add a newline to the pattern space,
+then append the next line of input to the pattern space.
+If there is no more input then @command{sed} exits without processing
+any more commands.
+
+@item P
+@findex P (print first line) command

+The @var{label} may be omitted, in which case the next cycle is started.

+
+@node Extended Commands
+@section Commands Specific to @value{SSED}
+
+These commands are specific to @value{SSED}, so you
+must use them with care and only when you are sure that
+hindering portability is not evil.  They allow you to check
+for @value{SSED} extensions or to do tasks that are required
+quite often, yet are unsupported by standard @command{sed}s.
+
+@table @code
+@item e [@var{command}]
+@findex e (evaluate) command
+@cindex Evaluate Bourne-shell commands
+@cindex Subprocesses
+@cindex @value{SSEDEXT}, evaluating Bourne-shell commands
+@cindex @value{SSEDEXT}, subprocesses
+This command allows one to pipe input from a shell command
+into pattern space.  Without parameters, the @code{e} command
+executes the command that is found in pattern space and
+replaces the pattern space with the output; a trailing newline
+is suppressed.
+
+If a parameter is specified, instead, the @code{e} command
+interprets it as a command and sends its output to the output stream.
+The command can run across multiple lines, all but the last ending with
+a back-slash.
+
+In both cases, the results are undefined if the command to be
+executed contains a @sc{nul} character.
+
+Note that, unlike the @code{r} command, the output of the command will
+be printed immediately; the @code{r} command instead delays the output
+to the end of the current cycle.
+
+@item F
+@findex F (File name) command
+@cindex Printing file name
+@cindex File name, printing
+Print out the file name of the current input file (with a trailing
+newline).
+
+@item L @var{n}
+@findex L (fLow paragraphs) command
+@cindex Reformat pattern space
+@cindex Reformatting paragraphs
+@cindex @value{SSEDEXT}, reformatting paragraphs
+@cindex @value{SSEDEXT}, @code{L} command
+This @value{SSED} extension fills and joins lines in pattern space
+to produce output lines of (at most) @var{n} characters, like
+@code{fmt} does; if @var{n} is omitted, the default as specified
+on the command line is used.  This command is considered a failed
+experiment and unless there is enough request (which seems unlikely)
+will be removed in future versions.
+
+@ignore
+Blank lines, spaces between words, and indentation are
+preserved in the output; successive input lines with different
+indentation are not joined; tabs are expanded to 8 columns.
+
+If the pattern space contains multiple lines, they are joined, but
+since the pattern space usually contains a single line, the behavior
+of a simple @code{L;d} script is the same as @samp{fmt -s} (i.e.,
+it does not join short lines to form longer ones).
+
+@var{n} specifies the desired line-wrap length; if omitted,
+the default as specified on the command line is used.
+@end ignore
+
+@item Q [@var{exit-code}]
+This command only accepts a single address.
+
+@findex Q (silent Quit) command
+@cindex @value{SSEDEXT}, quitting silently
+@cindex @value{SSEDEXT}, returning an exit code
+@cindex Quitting
+This command is the same as @code{q}, but will not print the
+contents of pattern space.  Like @code{q}, it provides the
+ability to return an exit code to the caller.
+
+This command can be useful because the only alternative ways
+to accomplish this apparently trivial function are to use
+the @option{-n} option (which can unnecessarily complicate
+your script) or resorting to the following snippet, which
+wastes time by reading the whole file without any visible effect:
+
+@example
+:eat
+$d       @i{@r{Quit silently on the last line}}
+N        @i{@r{Read another line, silently}}
+g        @i{@r{Overwrite pattern space each time to save memory}}
+b eat
+@end example
+
+@item R @var{filename}
+@findex R (read line) command
+@cindex Read text from a file
+@cindex @value{SSEDEXT}, reading a file a line at a time
+@cindex @value{SSEDEXT}, @code{R} command
+@cindex @value{SSEDEXT}, @file{/dev/stdin} file
+Queue a line of @var{filename} to be read and
+inserted into the output stream at the end of the current cycle,
+or when the next input line is read.
+Note that if @var{filename} cannot be read, or if its end is
+reached, no line is appended, without any error indication.
+
+As with the @code{r} command, the special value @file{/dev/stdin}
+is supported for the file name, which reads a line from the
+standard input.
+
+@item T @var{label}
+@findex T (test and branch if failed) command
+@cindex @value{SSEDEXT}, branch if @code{s///} failed
+@cindex Branch to a label, if @code{s///} failed
+@cindex Conditional branch
+Branch to @var{label} only if there have been no successful
+@code{s}ubstitutions since the last input line was read or
+conditional branch was taken. The @var{label} may be omitted,
+in which case the next cycle is started.
+
+@item v @var{version}
+@findex v (version) command
+@cindex @value{SSEDEXT}, checking for their presence
+@cindex Requiring @value{SSED}
+This command does nothing, but makes @command{sed} fail if
+@value{SSED} extensions are not supported, simply because other
+versions of @command{sed} do not implement it.  In addition, you
+can specify the version of @command{sed} that your script
+requires, such as @code{4.0.5}.  The default is @code{4.0}
+because that is the first version that implemented this command.
+
+This command enables all @value{SSEDEXT} even if
+@env{POSIXLY_CORRECT} is set in the environment.
+
+@item W @var{filename}
+@findex W (write first line) command
+@cindex Write first line to a file
+@cindex @value{SSEDEXT}, writing first line to a file
+Write to the given filename the portion of the pattern space up to
+the first newline.  Everything said under the @code{w} command about
+file handling holds here too.
+
+@item z
+@findex z (Zap) command
+@cindex @value{SSEDEXT}, emptying pattern space
+@cindex Emptying pattern space
+This command empties the content of pattern space.  It is
+usually the same as @samp{s/.*//}, but is more efficient
+and works in the presence of invalid multibyte sequences
+in the input stream.  @sc{posix} mandates that such sequences
+are @emph{not} matched by @samp{.}, so that there is no portable
+way to clear @command{sed}'s buffers in the middle of the
+script in most multibyte locales (including UTF-8 locales).

+
+@node Escapes
+@section @acronym{GNU} Extensions for Escapes in Regular Expressions
+
+@cindex @acronym{GNU} extensions, special escapes
+Until this chapter, we have only encountered escapes of the form
+@samp{\^}, which tell @command{sed} not to interpret the circumflex
+as a special character, but rather to take it literally.  For
+example, @samp{\*} matches a single asterisk rather than zero
+or more backslashes.
+
+@cindex @code{POSIXLY_CORRECT} behavior, escapes
+This chapter introduces another kind of escape@footnote{All
+the escapes introduced here are @acronym{GNU}
+extensions, with the exception of @code{\n}.  In basic regular
+expression mode, setting @code{POSIXLY_CORRECT} disables them inside
+bracket expressions.}---that
+is, escapes that are applied to a character or sequence of characters
+that ordinarily are taken literally, and that @command{sed} replaces
+with a special character.  This provides a way
+of encoding non-printable characters in patterns in a visible manner.
+There is no restriction on the appearance of non-printing characters
+in a @command{sed} script but when a script is being prepared in the
+shell or by text editing, it is usually easier to use one of
+the following escape sequences than the binary character it
+represents:
+
+The list of these escapes is:
+
+@table @code
+@item \a
+Produces or matches a @sc{bel} character, that is an ``alert'' (@sc{ascii} 7).
+
+@item \f
+Produces or matches a form feed (@sc{ascii} 12).
+
+@item \n
+Produces or matches a newline (@sc{ascii} 10).
+
+@item \r
+Produces or matches a carriage return (@sc{ascii} 13).
+
+@item \t
+Produces or matches a horizontal tab (@sc{ascii} 9).
+
+@item \v
+Produces or matches a so called ``vertical tab'' (@sc{ascii} 11).
+
+@item \c@var{x}
+Produces or matches @kbd{@sc{Control}-@var{x}}, where @var{x} is
+any character.  The precise effect of @samp{\c@var{x}} is as follows:
+if @var{x} is a lower case letter, it is converted to upper case.
+Then bit 6 of the character (hex 40) is inverted.  Thus @samp{\cz} becomes
+hex 1A, but @samp{\c@{} becomes hex 3B, while @samp{\c;} becomes hex 7B.
+
+@item \d@var{xxx}
+Produces or matches a character whose decimal @sc{ascii} value is @var{xxx}.
+
+@item \o@var{xxx}
+@ifset PERL
+@item \@var{xxx}
+@end ifset
+Produces or matches a character whose octal @sc{ascii} value is @var{xxx}.
+@ifset PERL
+The syntax without the @code{o} is active in Perl mode, while the one
+with the @code{o} is active in the normal or extended @sc{posix} regular
+expression modes.
+@end ifset
+
+@item \x@var{xx}
+Produces or matches a character whose hexadecimal @sc{ascii} value is @var{xx}.
+@end table
+
+@samp{\b} (backspace) was omitted because of the conflict with
+the existing ``word boundary'' meaning.
+
+Other escapes match a particular character class and are valid only in
+regular expressions:
+
+@table @code
+@item \w
+Matches any ``word'' character.  A ``word'' character is any
+letter or digit or the underscore character.
+
+@item \W
+Matches any ``non-word'' character.
+
+@item \b
+Matches a word boundary; that is it matches if the character
+to the left is a ``word'' character and the character to the
+right is a ``non-word'' character, or vice-versa.
+
+@item \B
+Matches everywhere but on a word boundary; that is it matches
+if the character to the left and the character to the right
+are either both ``word'' characters or both ``non-word''
+characters.
+
+@item \`
+Matches only at the start of pattern space.  This is different
+from @code{^} in multi-line mode.
+
+@item \'
+Matches only at the end of pattern space.  This is different
+from @code{$} in multi-line mode.
+
+@ifset PERL
+@item \G
+Match only at the start of pattern space or, when doing a global
+substitution using the @code{s///g} command and option, at
+the end-of-match position of the prior match.  For example,
+@samp{s/\Ga/Z/g} will change an initial run of @code{a}s to
+a run of @code{Z}s

+@section Centering Lines
+
+This script centers all lines of a file on a 80 columns width.
+To change that width, the number in @code{\@{@dots{}\@}} must be

+
+Note how the buffer commands are used to separate parts in
+the regular expressions to be matched---this is a common
+technique.

+@node Increment a number
+@section Increment a Number
+
+This script is one of a few that demonstrate how to do arithmetic
+in @command{sed}.  This is indeed possible,@footnote{@command{sed} guru Greg
+Ubben wrote an implementation of the @command{dc} @sc{rpn} calculator!
+It is distributed together with sed.} but must be done manually.
+
+To increment one number you just add 1 to last digit, replacing
+it by the following digit.  There is one exception: when the digit
+is a nine the previous digits must be also incremented until you
+don't have a nine.
+
+This solution by Bruno Haible is very clever and smart because
+it uses a single buffer; if you don't have this limitation, the
+algorithm used in @ref{cat -n, Numbering lines}, is faster.

+@node Rename files to lower case
+@section Rename Files to Lower Case
+
+This is a pretty strange use of @command{sed}.  We transform text, and
+transform it to be shell commands, then just feed them to shell.
+Don't worry, even worse hacks are done when using @command{sed}; I have
+seen a script converting the output of @command{date} into a @command{bc}
+program!
+
+The main body of this is the @command{sed} script, which remaps the name
+from lower to upper (or vice-versa) and even checks out 
+if the remapped name is the same as the original name.
+Note how the script is parameterized using shell

+
+Note the @code{tx} command before the definition of the label.

+Imaginative readers will find uses for this script.  An example

+
+Note that on implementations other than @acronym{GNU} @command{sed}
+@ifset PERL

+@end ifset
+this script might easily overflow internal buffers.
+

+
+@group
+# from the second line, the buffer (which contains all previous lines)

+@c end---------------------------------------------
+
+@node cat -n
+@section Numbering Lines
+
+This script replaces @samp{cat -n}; in fact it formats its output
+exactly like @acronym{GNU} @command{cat} does.
+
+Of course this is completely useless and for two reasons:  first,
+because somebody else did it in C, second, because the following
+Bourne-shell script could be used for the same purpose and would
+be much faster:
+
+@c start-------------------------------------------
+@example
+@group
+#! /bin/sh
+sed -e "=" $@@ | sed -e '
+  s/^/      /
+  N
+  s/^ *\(......\)\n/\1  /
+'
+@end group
+@end example
+@c end---------------------------------------------
+
+It uses @command{sed} to print the line number, then groups lines two
+by two using @code{N}.  Of course, this script does not teach as much as
+the one presented below.
+
+The algorithm used for incrementing uses both buffers, so the line
+is printed as soon as possible and then discarded.  The number
+is split so that changing digits go in a buffer and unchanged ones go
+in the other; the changed digits are modified in a single step
+(using a @code{y} command).  The line number for the next line
+is then composed and stored in the hold space, to be used in the
+next iteration.
+
+@c start-------------------------------------------
+@example
+#!/usr/bin/sed -nf
+

+@node wc -c
+@section Counting Characters
+
+This script shows another way to do arithmetic with @command{sed}.
+In this case we have to add possibly large numbers, so implementing
+this by successive increments would not be feasible (and possibly
+even more complicated to contrive than this script).
+
+The approach is to map numbers to letters, kind of an abacus
+implemented with @command{sed}.  @samp{a}s are units, @samp{b}s are
+tens and so on: we simply add the number of characters
+on the current line as units, and then propagate the carry
+to tens, hundreds, and so on.
+
+As usual, running totals are kept in hold space.
+
+On the last line, we convert the abacus form back to decimal.
+For the sake of variety, this is done with a loop rather than
+with some 80 @code{s} commands@footnote{Some implementations
+have a limit of 199 commands per script}: first we
+convert units, removing @samp{a}s from the number; then we
+rotate letters so that tens become @samp{a}s, and so on
+until no more letters remain.
+
+@c start-------------------------------------------
+@example
+#!/usr/bin/sed -nf
+
+@group
+# Add n+1 a's to hold space (+1 is for the newline)
+s/./a/g

+@node wc -w
+@section Counting Words
+
+This script is almost the same as the previous one, once each
+of the words on the line is converted to a single @samp{a}
+(in the previous script each letter was changed to an @samp{a}).
+
+It is interesting that real @command{wc} programs have optimized
+loops for @samp{wc -c}, so they are much slower at counting
+words rather than characters.  This script's bottleneck,
+instead, is arithmetic, and hence the word-counting one
+is faster (it has to manage smaller numbers).
+
+Again, the common parts are not commented to show the importance
+of commenting @command{sed} scripts.

+@node wc -l
+@section Counting Lines
+
+No strange things are done now, because @command{sed} gives us
+@samp{wc -l} functionality for free!!! Look:
+
+@c start-------------------------------------------
+@example
+@group
+#!/usr/bin/sed -nf
+$=
+@end group
+@end example
+@c end---------------------------------------------
+
+@node head
+@section Printing the First Lines
+
+This script is probably the simplest useful @command{sed} script.
+It displays the first 10 lines of input; the number of displayed
+lines is right before the @code{q} command.
+
+@c start-------------------------------------------
+@example
+@group
+#!/usr/bin/sed -f
+10q
+@end group
+@end example
+@c end---------------------------------------------
+
+@node tail
+@section Printing the Last Lines
+
+Printing the last @var{n} lines rather than the first is more complex
+but indeed possible.  @var{n} is encoded in the second line, before
+the bang character.
+
+This script is similar to the @command{tac} script in that it keeps the
+final output in the hold space and prints it at the end:
+
+@c start-------------------------------------------
+@example
+#!/usr/bin/sed -nf
+
+@group
+1! @{; H; g; @}
+1,10 !s/[^\n]*\n//
+$p
+h
+@end group
+@end example
+@c end---------------------------------------------
+
+Mainly, the scripts keeps a window of 10 lines and slides it
+by adding a line and deleting the oldest (the substitution command
+on the second line works like a @code{D} command but does not
+restart the loop).
+
+The ``sliding window'' technique is a very powerful way to write
+efficient and complex @command{sed} scripts, because commands like
+@code{P} would require a lot of work if implemented manually.
+
+To introduce the technique, which is fully demonstrated in the
+rest of this chapter and is based on the @code{N}, @code{P}
+and @code{D} commands, here is an implementation of @command{tail}
+using a simple ``sliding window.''
+
+This looks complicated but in fact the working is the same as
+the last script: after we have kicked in the appropriate number
+of lines, however, we stop using the hold space to keep inter-line
+state, and instead use @code{N} and @code{D} to slide pattern
+space by one line:
+
+@c start-------------------------------------------
+@example
+#!/usr/bin/sed -f
+
+@group
+1h
+2,10 @{; H; g; @}
+$q
+1,9d
+N
+D
+@end group
+@end example
+@c end---------------------------------------------
+
+Note how the first, second and fourth line are inactive after
+the first ten lines of input.  After that, all the script does
+is: exiting on the last line of input, appending the next input
+line to pattern space, and removing the first line.
+
+@node uniq
+@section Make Duplicate Lines Unique
+
+This is an example of the art of using the @code{N}, @code{P}
+and @code{D} commands, probably the most difficult to master.
+
+@c start-------------------------------------------
+@example
+@group
+#!/usr/bin/sed -f
+h
+@end group
+
+@group
+:b
+# On the last line, print and exit
+$b
+N
+/^\(.*\)\n\1$/ @{
+    # The two lines are identical.  Undo the effect of
+    # the n command.
+    g
+    bb
+@}
+@end group
+
+@group
+# If the @code{N} command had added the last line, print and exit
+$b
+@end group
+
+@group
+# The lines are different; print the first and go
+# back working on the second.
+P
+D
+@end group
+@end example
+@c end---------------------------------------------
+
+As you can see, we mantain a 2-line window using @code{P} and @code{D}.
+This technique is often used in advanced @command{sed} scripts.
+
+@node uniq -d
+@section Print Duplicated Lines of Input
+
+This script prints only duplicated lines, like @samp{uniq -d}.
+
+@c start-------------------------------------------
+@example
+#!/usr/bin/sed -nf
+
+@group
+$b
+N
+/^\(.*\)\n\1$/ @{
+    # Print the first of the duplicated lines
+    s/.*\n//
+    p
+@end group
+
+@group
+    # Loop until we get a different line
+    :b
+    $b
+    N
+    /^\(.*\)\n\1$/ @{
+        s/.*\n//
+        bb
+    @}
+@}
+@end group
+
+@group
+# The last line cannot be followed by duplicates
+$b
+@end group
+
+@group
+# Found a different one.  Leave it alone in the pattern space
+# and go back to the top, hunting its duplicates
+D
+@end group
+@end example
+@c end---------------------------------------------
+
+@node uniq -u
+@section Remove All Duplicated Lines
+
+This script prints only unique lines, like @samp{uniq -u}.
+
+@c start-------------------------------------------
+@example
+#!/usr/bin/sed -f
+
+@group
+# Search for a duplicate line --- until that, print what you find.
+$b
+N
+/^\(.*\)\n\1$/ ! @{
+    P
+    D
+@}
+@end group
+
+@group
+:c
+# Got two equal lines in pattern space.  At the
+# end of the file we simply exit
+$d
+@end group
+
+@group
+# Else, we keep reading lines with @code{N} until we
+# find a different one
+s/.*\n//
+N
+/^\(.*\)\n\1$/ @{
+    bc
+@}
+@end group
+
+@group
+# Remove the last instance of the duplicate line
+# and go back to the top
+D
+@end group
+@end example
+@c end---------------------------------------------
+
+@node cat -s
+@section Squeezing Blank Lines
+
+As a final example, here are three scripts, of increasing complexity
+and speed, that implement the same function as @samp{cat -s}, that is
+squeezing blank lines.
+
+The first leaves a blank line at the beginning and end if there are
+some already.
+
+@c start-------------------------------------------
+@example
+#!/usr/bin/sed -f
+
+@group
+# on empty lines, join with next
+# Note there is a star in the regexp
+:x
+/^\n*$/ @{
+N
+bx
+@}
+@end group
+
+@group
+# now, squeeze all '\n', this can be also done by:
+# s/^\(\n\)*/\1/
+s/\n*/\
+/
+@end group
+@end example
+@c end---------------------------------------------
+
+This one is a bit more complex and removes all empty lines
+at the beginning.  It does leave a single blank line at end
+if one was there.
+
+@c start-------------------------------------------
+@example
+#!/usr/bin/sed -f
+
+@group
+# delete all leading empty lines
+1,/^./@{
+/./!d
+@}
+@end group
+
+@group
+# on an empty line we remove it and all the following
+# empty lines, but one
+:x
+/./!@{
+N
+s/^\n$//
+tx
+@}
+@end group
+@end example
+@c end---------------------------------------------
+
+This removes leading and trailing blank lines.  It is also the
+fastest.  Note that loops are completely done with @code{n} and
+@code{b}, without relying on @command{sed} to restart the
+the script automatically at the end of a line.
+
+@c start-------------------------------------------
+@example
+#!/usr/bin/sed -nf
+
+@group
+# delete all (leading) blanks
+/./!d
+@end group
+
+@group
+# get here: so there is a non empty
+:x
+# print it
+p

+@node Limitations
+@chapter @value{SSED}'s Limitations and Non-limitations
+
+@cindex @acronym{GNU} extensions, unlimited line length
+@cindex Portability, line length limitations
+For those who want to write portable @command{sed} scripts,
+be aware that some implementations have been known to
+limit line lengths (for the pattern and hold spaces)
+to be no more than 4000 bytes.
+The @sc{posix} standard specifies that conforming @command{sed}
+implementations shall support at least 8192 byte line lengths.
+@value{SSED} has no built-in limit on line length;
+as long as it can @code{malloc()} more (virtual) memory,
+you can feed or construct lines as long as you like.
+
+However, recursion is used to handle subpatterns and indefinite
+repetition.  This means that the available stack space may limit
+the size of the buffer that can be processed by certain patterns.
+
+@ifset PERL
+There are some size limitations in the regular expression
+matcher but it is hoped that they will never in practice
+be relevant.  The maximum length of a compiled pattern
+is 65539 (sic) bytes.  All values in repeating quantifiers
+must be less than 65536.  The maximum nesting depth of
+all parenthesized subpatterns, including capturing and
+non-capturing subpatterns@footnote{The
+distinction is meaningful when referring to Perl-style
+regular expressions.}, assertions, and other types of
+subpattern, is 200.
+
+Also, @value{SSED} recognizes the @sc{posix} syntax
+@code{[.@var{ch}.]} and @code{[=@var{ch}=]}
+where @var{ch} is a ``collating element'', but these
+are not supported, and an error is given if they are
+encountered.
+
+Here are a few distinctions between the real Perl-style
+regular expressions and those that @option{-R} recognizes.
+
+@enumerate
+@item
+Lookahead assertions do not allow repeat quantifiers after them
+Perl permits them, but they do not mean what you
+might think. For example, @samp{(?!a)@{3@}} does not assert that the
+next three characters are not @samp{a}. It just asserts three times that the
+next character is not @samp{a} --- a waste of time and nothing else.
+
+@item
+Capturing subpatterns that occur inside  negative  lookahead
+head  assertions  are  counted,  but  their  entries are counted
+as empty in the second half of an @code{s} command.
+Perl sets its numerical variables from any such patterns
+that are matched before the assertion fails to match
+something (thereby succeeding), but only if the negative
+lookahead assertion contains just one branch.
+
+@item
+The following Perl escape sequences are not supported:
+@samp{\l}, @samp{\u}, @samp{\L}, @samp{\U}, @samp{\E},
+@samp{\Q}. In fact these are implemented by Perl's general
+string-handling and are not part of its pattern matching engine.
+
+@item
+The Perl @samp{\G} assertion is not supported as it is not
+relevant to single pattern matches.
+
+@item
+Fairly obviously, @value{SSED} does not support the @samp{(?@{code@})}
+and @samp{(?p@{code@})} constructions. However, there is some experimental
+support for recursive patterns using the non-Perl item @samp{(?R)}.
+
+@item
+There are at the time of writing some oddities in Perl
+5.005_02 concerned with the settings of captured strings
+when part of a pattern is repeated. For example, matching
+@samp{aba} against the pattern @samp{/^(a(b)?)+$/} sets
+@samp{$2}@footnote{@samp{$2} would be @samp{\2} in @value{SSED}.}
+to the value @samp{b}, but matching @samp{aabbaa}
+against @samp{/^(aa(bb)?)+$/} leaves @samp{$2}
+unset.  However, if the pattern is changed to
+@samp{/^(aa(b(b))?)+$/} then @samp{$2} (and @samp{$3}) are set.
+In Perl 5.004 @samp{$2} is set in both cases, and that is also
+true of @value{SSED}.
+
+@item
+Another as yet unresolved discrepancy is that in Perl
+5.005_02 the pattern @samp{/^(a)?(?(1)a|b)+$/} matches
+the string @samp{a}, whereas in @value{SSED} it does not.
+However, in both Perl and @value{SSED} @samp{/^(a)?a/} matched
+against @samp{a} leaves $1 unset.

+Email bug reports to @email{bug-sed@@gnu.org}.
+Also, please include the output of @samp{sed --version} in the body
+of your report if at all possible.
+
+Please do not send a bug report like this:
+
+@example
+@i{@i{@r{while building frobme-1.3.4}}}
+$ configure 
+@error{} sed: file sedscr line 1: Unknown option to 's'
+@end example
+
+If @value{SSED} doesn't configure your favorite package, take a
+few extra minutes to identify the specific problem and make a stand-alone
+test case.  Unlike other programs such as C compilers, making such test
+cases for @command{sed} is quite simple.
+
+A stand-alone test case includes all the data necessary to perform the
+test, and the specific invocation of @command{sed} that causes the problem.
+The smaller a stand-alone test case is, the better.  A test case should
+not involve something as far removed from @command{sed} as ``try to configure
+frobme-1.3.4''.  Yes, that is in principle enough information to look
+for the bug, but that is not a very practical prospect.
+
+Here are a few commonly reported bugs that are not bugs.
+
+@table @asis
+@item @code{N} command on the last line
+@cindex Portability, @code{N} command on the last line
+@cindex Non-bugs, @code{N} command on the last line
+
+Most versions of @command{sed} exit without printing anything when
+the @command{N} command is issued on the last line of a file.
+@value{SSED} prints pattern space before exiting unless of course
+the @command{-n} command switch has been specified.  This choice is
+by design.
+
+For example, the behavior of
+@example
+sed N foo bar
+@end example
+@noindent
+would depend on whether foo has an even or an odd number of
+lines@footnote{which is the actual ``bug'' that prompted the
+change in behavior}.  Or, when writing a script to read the
+next few lines following a pattern match, traditional
+implementations of @code{sed} would force you to write
+something like
+@example
+/foo/@{ $!N; $!N; $!N; $!N; $!N; $!N; $!N; $!N; $!N @}
+@end example
+@noindent
+instead of just
+@example
+/foo/@{ N;N;N;N;N;N;N;N;N; @}
+@end example
+
+@cindex @code{POSIXLY_CORRECT} behavior, @code{N} command
+In any case, the simplest workaround is to use @code{$d;N} in
+scripts that rely on the traditional behavior, or to set
+the @code{POSIXLY_CORRECT} variable to a non-empty value.
+
+@item Regex syntax clashes (problems with backslashes)
+@cindex @acronym{GNU} extensions, to basic regular expressions
+@cindex Non-bugs, regex syntax clashes
+@command{sed} uses the @sc{posix} basic regular expression syntax.  According to
+the standard, the meaning of some escape sequences is undefined in
+this syntax;  notable in the case of @command{sed} are @code{\|},
+@code{\+}, @code{\?}, @code{\`}, @code{\'}, @code{\<},
+@code{\>}, @code{\b}, @code{\B}, @code{\w}, and @code{\W}.
+
+As in all @acronym{GNU} programs that use @sc{posix} basic regular
+expressions, @command{sed} interprets these escape sequences as special
+characters.  So, @code{x\+} matches one or more occurrences of @samp{x}.
+@code{abc\|def} matches either @samp{abc} or @samp{def}.
+
+This syntax may cause problems when running scripts written for other
+@command{sed}s.  Some @command{sed} programs have been written with the
+assumption that @code{\|} and @code{\+} match the literal characters
+@code{|} and @code{+}.  Such scripts must be modified by removing the
+spurious backslashes if they are to be used with modern implementations
+of @command{sed}, like
+@ifset PERL
+@value{SSED} or
+@end ifset
+@acronym{GNU} @command{sed}.
+
+On the other hand, some scripts use s|abc\|def||g to remove occurrences
+of @emph{either} @code{abc} or @code{def}.  While this worked until
+@command{sed} 4.0.x, newer versions interpret this as removing the
+string @code{abc|def}.  This is again undefined behavior according to
+@acronym{POSIX}, and this interpretation is arguably more robust: older
+@command{sed}s, for example, required that the regex matcher parsed
+@code{\/} as @code{/} in the common case of escaping a slash, which is
+again undefined behavior; the new behavior avoids this, and this is good
+because the regex matcher is only partially under our control.
+
+@cindex @acronym{GNU} extensions, special escapes
+In addition, this version of @command{sed} supports several escape characters
+(some of which are multi-character) to insert non-printable characters
+in scripts (@code{\a}, @code{\c}, @code{\d}, @code{\o}, @code{\r},
+@code{\t}, @code{\v}, @code{\x}).  These can cause similar problems
+with scripts written for other @command{sed}s.
+
+@item @option{-i} clobbers read-only files
+@cindex In-place editing
+@cindex @value{SSEDEXT}, in-place editing
+@cindex Non-bugs, in-place editing
+
+In short, @samp{sed -i} will let you delete the contents of
+a read-only file, and in general the @option{-i} option
+(@pxref{Invoking sed, , Invocation}) lets you clobber
+protected files.  This is not a bug, but rather a consequence
+of how the Unix filesystem works.
+
+The permissions on a file say what can happen to the data
+in that file, while the permissions on a directory say what can
+happen to the list of files in that directory.  @samp{sed -i}
+will not ever open for writing  a file that is already on disk.
+Rather, it will work on a temporary file that is finally renamed
+to the original name: if you rename or delete files, you're actually
+modifying the contents of the directory, so the operation depends on
+the permissions of the directory, not of the file.  For this same
+reason, @command{sed} does not let you use @option{-i} on a writeable file
+in a read-only directory, and will break hard or symbolic links when
+@option{-i} is used on such a file.
+
+@item @code{0a} does not work (gives an error)
+@cindex @code{0} address
+@cindex @acronym{GNU} extensions, @code{0} address
+@cindex Non-bugs, @code{0} address
+
+There is no line 0.  0 is a special address that is only used to treat
+addresses like @code{0,/@var{RE}/} as active when the script starts: if
+you write @code{1,/abc/d} and the first line includes the word @samp{abc},
+then that match would be ignored because address ranges must span at least
+two lines (barring the end of the file); but what you probably wanted is
+to delete every line up to the first one including @samp{abc}, and this
+is obtained with @code{0,/abc/d}.
+
+@ifclear PERL
+@item @code{[a-z]} is case insensitive
+@cindex Non-bugs, localization-related
+
+You are encountering problems with locales.  POSIX mandates that @code{[a-z]}
+uses the current locale's collation order -- in C parlance, that means using
+@code{strcoll(3)} instead of @code{strcmp(3)}.  Some locales have a
+case-insensitive collation order, others don't.
+
+Another problem is that @code{[a-z]} tries to use collation symbols.
+This only happens if you are on the @acronym{GNU} system, using
+@acronym{GNU} libc's regular expression matcher instead of compiling the
+one supplied with @acronym{GNU} sed.  In a Danish locale, for example,
+the regular expression @code{^[a-z]$} matches the string @samp{aa},
+because this is a single collating symbol that comes after @samp{a}
+and before @samp{b}; @samp{ll} behaves similarly in Spanish
+locales, or @samp{ij} in Dutch locales.
+
+To work around these problems, which may cause bugs in shell scripts, set
+the @env{LC_COLLATE} and @env{LC_CTYPE} environment variables to @samp{C}.
+
+@item @code{s/.*//} does not clear pattern space
+@cindex Non-bugs, localization-related
+@cindex @value{SSEDEXT}, emptying pattern space
+@cindex Emptying pattern space
+
+This happens if your input stream includes invalid multibyte
+sequences.  @sc{posix} mandates that such sequences
+are @emph{not} matched by @samp{.}, so that @samp{s/.*//} will not clear
+pattern space as you would expect.  In fact, there is no way to clear
+sed's buffers in the middle of the script in most multibyte locales
+(including UTF-8 locales).  For this reason, @value{SSED} provides a `z'
+command (for `zap') as an extension.
+
+To work around these problems, which may cause bugs in shell scripts, set
+the @env{LC_COLLATE} and @env{LC_CTYPE} environment variables to @samp{C}.

+
+The only difference between basic and extended regular expressions is in
+the behavior of a few characters: @samp{?}, @samp{+}, parentheses,
+braces (@samp{@{@}}), and @samp{|}.  While basic regular expressions
+require these to be escaped if you want them to behave as special
+characters, when using extended regular expressions you must escape
+them if you want them @emph{to match a literal character}.  @samp{|}
+is special here because @samp{\|} is a GNU extension -- standard
+basic regular expressions do not provide its functionality.
+
+@noindent
+Examples:
+@table @code
+@item abc?

+@item c\+
+becomes @samp{c+} when using extended regular expressions.  It matches

+
+@node Backslash
+@appendixsec Backslash
+@cindex Perl-style regular expressions, escaped sequences
+
+There are a few difference in the handling of backslashed 
+sequences in Perl mode.
+
+First of all, there are no @code{\o} and @code{\d} sequences.
+@sc{ascii} values for characters can be specified in octal
+with a @code{\@var{xxx}} sequence, where @var{xxx} is a
+sequence of up to three octal digits.  If the first digit
+is a zero, the treatment of the sequence is straightforward;
+just note that if the character that follows the escaped digit
+is itself an octal digit, you have to supply three octal digits
+for @var{xxx}.  For example @code{\07} is a @sc{bel} character
+rather than a @sc{nul} and a literal @code{7} (this sequence is
+instead represented by @code{\0007}).
+
+@cindex Perl-style regular expressions, backreferences
+The handling of a backslash followed by a digit other than 0
+is complicated.  Outside a character class, @command{sed} reads it
+and any following digits as a decimal number. If the number
+is less than 10, or if there have been at least that many
+previous capturing left parentheses in the expression, the
+entire sequence is taken as a back reference. A description
+of how this works is given later, following the discussion
+of parenthesized subpatterns.
+
+Inside a character class, or if the decimal number is
+greater than 9 and there have not been that many capturing
+subpatterns, @command{sed} re-reads up to three octal digits following
+the backslash, and generates a single byte from the
+least significant 8 bits of the value. Any subsequent digits
+stand for themselves.  For example:
+
+@example
+\040  @i{@r{is another way of writing a space}}
+\40   @i{@r{is the same, provided there are fewer than 40}}
+      @i{@r{previous capturing subpatterns}}
+\7    @i{@r{is always a back reference}}
+\011  @i{@r{is always a tab}}
+\11   @i{@r{might be a back reference, or another way of writing a tab}}
+\0113 @i{@r{is a tab followed by the character @samp{3}}}
+\113  @i{@r{is the character with octal code 113 (since there}}
+      @i{@r{can be no more than 99 back references)}}
+\377  @i{@r{is a byte consisting entirely of 1 bits (@sc{ascii} 255)}}
+\81   @i{@r{is either a back reference, or a binary zero}}
+      @i{@r{followed by the two characters @samp{81}}}
+@end example
+
+Note that octal values of 100 or greater must not be introduced
+by a leading zero, because no more than three octal
+digits are ever read. Note that this applies only to the LHS 
+pattern; it is not possible yet to specify more than 9 backreferences 
+on the RHS of the `s' command.
+
+All the sequences that define a single byte value can be
+used both inside and outside character classes. In addition,
+inside a character class, the sequence @code{\b} is interpreted
+as the backspace character (hex 08). Outside a character
+class it has a different meaning (see below).
+
+In addition, there are four additional escapes specifying
+generic character classes (like @code{\w} and @code{\W} do):
+
+@cindex Perl-style regular expressions, character classes
+@table @samp
+@item \d
+Matches any decimal digit
+
+@item \D
+Matches any character that is not a decimal digit
+@end table
+
+In Perl mode, these character type sequences can appear both inside and
+outside character classes. Instead, in @sc{posix} mode these sequences
+(as well as @code{\w} and @code{\W}) are treated as two literal characters
+(a backslash and a letter) inside square brackets.
+
+Escaped sequences specifying assertions are also different in
+Perl mode.  An assertion specifies a condition that has to be met
+at a particular point in a match, without consuming any
+characters from the subject string. The use of subpatterns
+for more complicated assertions is described below.  The
+backslashed assertions are
+
+@cindex Perl-style regular expressions, assertions
+@table @samp
+@item \b
+Asserts that the point is at a word boundary.
+A word boundary is a position in the subject string where
+the current character and the previous character do not both
+match @code{\w} or @code{\W} (i.e. one matches @code{\w} and
+the other matches @code{\W}), or the start or end of the string
+if the first or last character matches @code{\w}, respectively.
+
+@item \B
+Asserts that the point is not at a word boundary.
+
+@item \A
+Asserts the matcher is at the start of pattern space (independent
+of multiline mode).
+
+@item \Z
+Asserts the matcher is at the end of pattern space,
+or at a newline before the end of pattern space (independent of
+multiline mode)
+
+@item \z
+Asserts the matcher is at the end of pattern space (independent
+of multiline mode)
+@end table
+
+These assertions may not appear in character classes (but
+note that @code{\b} has a different meaning, namely the
+backspace character, inside a character class).
+Note that Perl mode does not support directly assertions
+for the beginning and the end of word; the @acronym{GNU} extensions
+@code{\<} and @code{\>} achieve this purpose in @sc{posix} mode
+instead.
+
+The @code{\A}, @code{\Z}, and @code{\z} assertions differ
+from the traditional circumflex and dollar sign (described below)
+in that they only ever match at the very start and end of the
+subject string, whatever options are set; in particular @code{\A}
+and @code{\z} are the same as the @acronym{GNU} extensions
+@code{\`} and @code{\'} that are active in @sc{posix} mode.
+
+@node Circumflex/dollar sign/period
+@appendixsec Circumflex, dollar sign, period
+@cindex Perl-style regular expressions, newlines
+
+Outside a character class, in the default matching mode, the
+circumflex character is an assertion which is true only if
+the current matching point is at the start of the subject
+string.  Inside a character class, the circumflex has an entirely
+different meaning (see below).
+
+The circumflex need not be the first character of the pattern if
+a number of alternatives are involved, but it should be the
+first thing in each alternative in which it appears if the
+pattern is ever to match that branch. If all possible alternatives,
+start with a circumflex, that is, if the pattern is
+constrained to match only at the start of the subject, it is
+said to be an @dfn{anchored} pattern. (There are also other constructs
+structs that can cause a pattern to be anchored.)
+
+A dollar sign is an assertion which is true only if the
+current matching point is at the end of the subject string,
+or immediately before a newline character that is the last
+character in the string (by default).  A dollar sign need not be the
+last character of the pattern if a number of alternatives
+are involved, but it should be the last item in any branch
+in which it appears.  A dollar sign has no special meaning in a
+character class.
+
+@cindex Perl-style regular expressions, multiline
+The meanings of the circumflex and dollar sign characters are
+changed if the @code{M} modifier option is used. When this is
+the case, they match immediately after and immediately
+before an internal @code{\n} character, respectively, in addition
+to matching at the start and end of the subject string.  For
+example, the pattern @code{/^abc$/} matches the subject string
+@samp{def\nabc} in multiline mode, but not otherwise.  Consequently,
+patterns that are anchored in single line mode
+because all branches start with @code{^} are not anchored in
+multiline mode.
+
+@cindex Perl-style regular expressions, multiline
+Note that the sequences @code{\A}, @code{\Z}, and @code{\z}
+can be used to match the start and end of the subject in both
+modes, and if all branches of a pattern start with @code{\A}
+is it always anchored, whether the @code{M} modifier is set or not.
+
+@cindex Perl-style regular expressions, single line
+Outside a character class, a dot in the pattern matches any
+one character in the subject, including a non-printing character,
+but not (by default) newline.  If the @code{S} modifier is used,
+dots match newlines as well.  Actually, the handling of
+dot is entirely independent of the handling of circumflex
+and dollar sign, the only relationship being that they both
+involve newline characters. Dot has no special meaning in a
+character class.
+
+@node Square brackets
+@appendixsec Square brackets
+@cindex Perl-style regular expressions, character classes
+
+An opening square bracket introduces a character class, terminated
+by a closing square bracket.  A closing square bracket on its own
+is not special.  If a closing square bracket is required as a
+member of the class, it should be the first data character in
+the class (after an initial circumflex, if present) or escaped with a backslash.
+
+A character class matches a single character in the subject;
+the character must be in the set of characters defined by
+the class, unless the first character in the class is a circumflex,
+in which case the subject character must not be in
+the set defined by the class. If a circumflex is actually
+required as a member of the class, ensure it is not the
+first character, or escape it with a backslash.
+
+For example, the character class [aeiou] matches any lower
+case vowel, while [^aeiou] matches any character that is not
+a lower case vowel. Note that a circumflex is just a convenient
+venient notation for specifying the characters which are in
+the class by enumerating those that are not. It is not an
+assertion: it still consumes a character from the subject
+string, and fails if the current pointer is at the end of
+the string.
+
+@cindex Perl-style regular expressions, case-insensitive
+When caseless matching is set, any letters in a class
+represent both their upper case and lower case versions, so
+for example, a caseless @code{[aeiou]} matches uppercase
+and lowercase @samp{A}s, and a caseless @code{[^aeiou]}
+does not match @samp{A}, whereas a case-sensitive version would.
+
+@cindex Perl-style regular expressions, single line
+@cindex Perl-style regular expressions, multiline
+The newline character is never treated in any special way in
+character classes, whatever the setting of the @code{S} and
+@code{M} options (modifiers) is.  A class such as @code{[^a]} will
+always match a newline.
+
+The minus (hyphen) character can be used to specify a range
+of characters in a character class.  For example, @code{[d-m]}
+matches any letter between d and m, inclusive.  If a minus
+character is required in a class, it must be escaped with a
+backslash or appear in a position where it cannot be interpreted
+as indicating a range, typically as the first or last
+character in the class.
+
+It is not possible to have the literal character @code{]} as the
+end character of a range.  A pattern such as @code{[W-]46]} is
+interpreted as a class of two characters (@code{W} and @code{-})
+followed by a literal string @code{46]}, so it would match
+@samp{W46]} or @samp{-46]}. However, if the @code{]} is escaped
+with a backslash it is interpreted as the end of range, so
+@code{[W-\]46]} is interpreted as a single class containing a
+range followed by two separate characters. The octal or
+hexadecimal representation of @code{]} can also be used to end a range.
+
+Ranges operate in @sc{ascii} collating sequence. They can also be
+used for characters specified numerically, for example
+@code{[\000-\037]}. If a range that includes letters is used when
+caseless matching is set, it matches the letters in either
+case. For example, a caseless @code{[W-c]} is equivalent to
+@code{[][\^_`wxyzabc]}, matched caselessly, and if character
+tables for the French locale are in use, @code{[\xc8-\xcb]}
+matches accented E characters in both cases.
+
+Unlike in @sc{posix} mode, the character types @code{\d},
+@code{\D}, @code{\s}, @code{\S}, @code{\w}, and @code{\W}
+may also appear in a character class, and add the characters
+that they match to the class. For example, @code{[\dABCDEF]} matches any
+hexadecimal digit.  A circumflex can conveniently be used
+with the upper case character types to specify a more restricted
+set of characters than the matching lower case type.
+For example, the class @code{[^\W_]} matches any letter or digit,
+but not underscore.
+
+All non-alphameric characters other than @code{\}, @code{-},
+@code{^} (at the start) and the terminating @code{]}
+are non-special in character classes, but it does no harm
+if they are escaped.
+
+Perl 5.6 supports the @sc{posix} notation for character classes, which
+uses names enclosed by @code{[:} and @code{:]} within the enclosing
+square brackets, and @value{SSED} supports this notation as well.
+For example,
+
+@example
+[01[:alpha:]%]
+@end example
+
+@noindent
+matches @samp{0}, @samp{1}, any alphabetic character, or @samp{%}.
+The supported class names are
+
+@table @code
+@item alnum
+Matches letters and digits
+
+@item alpha
+Matches letters
+
+@item ascii
+Matches character codes 0 - 127
+
+@item cntrl
+Matches control characters
+
+@item digit
+Matches decimal digits (same as \d)
+
+@item graph
+Matches printing characters, excluding space
+
+@item lower
+Matches lower case letters
+
+@item print
+Matches printing characters, including space
+
+@item punct
+Matches printing characters, excluding letters and digits
+
+@item space
+Matches white space (same as \s)
+
+@item upper
+Matches upper case letters
+
+@item word
+Matches ``word'' characters (same as \w)
+
+@item xdigit
+Matches hexadecimal digits
+@end table
+
+The names @code{ascii} and @code{word} are extensions valid only in
+Perl mode.  Another Perl extension is negation, which is
+indicated by a circumflex character after the colon. For example,
+
+@example
+[12[:^digit:]]
+@end example
+
+@noindent
+matches @samp{1}, @samp{2}, or any non-digit.
+
+@node Options setting

+@cindex Perl-style regular expressions, case-insensitive
+@cindex Perl-style regular expressions, multiline
+@cindex Perl-style regular expressions, single line
+@cindex Perl-style regular expressions, extended
+
+The settings of the @code{I}, @code{M}, @code{S}, @code{X}
+modifiers can be changed from within the pattern by
+a sequence of Perl option letters enclosed between @code{(?}
+and @code{)}. The option letters must be lowercase.
+
+For example, @code{(?im)} sets caseless, multiline matching. It is
+also possible to unset these options by preceding the letter
+with a hyphen; you can also have combined settings and unsettings:
+@code{(?im-sx)} sets caseless and multiline matching,
+while unsets single line matching (for dots) and extended
+whitespace interpretation.  If a letter appears both before
+and after the hyphen, the option is unset.
+
+The scope of these option changes depends on where in the
+pattern the setting occurs. For settings that are outside
+any subpattern (defined below), the effect is the same as if
+the options were set or unset at the start of matching. The
+following patterns all behave in exactly the same way:
+
+@example
+(?i)abc
+a(?i)bc
+ab(?i)c
+abc(?i)
+@end example
+
+which in turn is the same as specifying the pattern abc with
+the @code{I} modifier.  In other words, ``top level'' settings
+apply to the whole pattern (unless there are other
+changes inside subpatterns). If there is more than one setting
+of the same option at top level, the rightmost setting
+is used.
+
+If an option change occurs inside a subpattern, the effect
+is different.  This is a change of behaviour in Perl 5.005.
+An option change inside a subpattern affects only that part
+of the subpattern @emph{that follows} it, so
+
+@example
+(a(?i)b)c
+@end example
+
+@noindent
+matches abc and aBc and no other  strings  (assuming
+case-sensitive matching is used).  By this means, options can
+be made to have different settings in different parts of the
+pattern.  Any changes made in one alternative do carry on
+into subsequent branches within the same subpattern.  For
+example,
+
+@example
+(a(?i)b|c)
+@end example
+
+@noindent
+matches @samp{ab}, @samp{aB}, @samp{c}, and @samp{C},
+even though when matching @samp{C} the first branch is
+abandoned before the option setting.
+This is because the effects of option settings happen at
+compile time. There would be some very weird behaviour otherwise.
+
+@ignore
+There are two PCRE-specific options PCRE_UNGREEDY and PCRE_EXTRA
+that can be changed in the same way as the Perl-compatible options by
+using the characters U and X respectively.  The (?X) flag
+setting is special in that it must always occur earlier in
+the pattern than any of the additional features it turns on,
+even when it is at top level. It is best put at the start.
+@end ignore
+
+
+@node Non-capturing subpatterns
+@appendixsec Non-capturing subpatterns
+@cindex Perl-style regular expressions, non-capturing subpatterns
+
+Marking part of a pattern as a subpattern does two things.
+On one hand, it localizes a set of alternatives; on the other
+hand, it sets up the subpattern as a capturing subpattern (as
+defined above).  The subpattern can be backreferenced and
+referenced in the right side of @code{s} commands.
+
+For example, if the string @samp{the red king} is matched against
+the pattern
+
+@example
+the ((red|white) (king|queen))
+@end example
+
+@noindent
+the captured substrings are @samp{red king}, @samp{red},
+and @samp{king}, and are numbered 1, 2, and 3.
+
+The fact that plain parentheses fulfil two functions is not
+always helpful.  There are often times when a grouping
+subpattern is required without a capturing requirement.  If an
+opening parenthesis is followed by @code{?:}, the subpattern does
+not do any capturing, and is not counted when computing the
+number of any subsequent capturing subpatterns. For example,
+if the string @samp{the white queen} is matched against the pattern
+
+@example
+the ((?:red|white) (king|queen))
+@end example
+
+@noindent
+the captured substrings are @samp{white queen} and @samp{queen},
+and are numbered 1 and 2. The maximum number of captured
+substrings is 99, while the maximum number of all subpatterns,
+both capturing and non-capturing, is 200.
+
+As a convenient shorthand, if any option settings are
+equired at the start of a non-capturing subpattern, the
+option letters may appear between the @code{?} and the
+@code{:}.  Thus the two patterns
+
+@example
+(?i:saturday|sunday)
+(?:(?i)saturday|sunday)
+@end example
+
+@noindent
+match exactly the same set of strings.  Because alternative
+branches are tried from left to right, and options are not
+reset until the end of the subpattern is reached, an option
+setting in one branch does affect subsequent branches, so
+the above patterns match @samp{SUNDAY} as well as @samp{Saturday}.
+
+
+@node Repetition
+@appendixsec Repetition
+@cindex Perl-style regular expressions, repetitions
+
+Repetition is specified by quantifiers, which can follow any
+of the following items:
+
+@itemize @bullet
+@item
+a single character, possibly escaped
+
+@item
+the @code{.} special character
+
+@item
+a character class
+
+@item
+a back reference (see next section)
+
+@item
+a parenthesized subpattern (unless it is an assertion; @pxref{Assertions})
+@end itemize
+
+The general repetition quantifier specifies a minimum and
+maximum number of permitted matches, by giving the two
+numbers in curly brackets (braces), separated by a comma.
+The numbers must be less than 65536, and the first must be
+less than or equal to the second. For example:
+
+@example
+z@{2,4@}
+@end example
+
+@noindent
+matches @samp{zz}, @samp{zzz}, or @samp{zzzz}. A closing brace on its own
+is not a special character. If the second number is omitted,
+but the comma is present, there is no upper limit; if the
+second number and the comma are both omitted, the quantifier
+specifies an exact number of required matches. Thus
+
+@example
+[aeiou]@{3,@}
+@end example
+
+@noindent
+matches at least 3 successive vowels, but may match many
+more, while
+
+@example
+\d@{8@}
+@end example
+
+@noindent
+matches exactly 8 digits.  An opening curly bracket that
+appears in a position where a quantifier is not allowed, or
+one that does not match the syntax of a quantifier, is taken
+as a literal character. For example, @{,6@} is not a quantifier,
+but a literal string of four characters.@footnote{It
+raises an error if @option{-R} is not used.}
+
+The quantifier @samp{@{0@}} is permitted, causing the expression to
+behave as if the previous item and the quantifier were not
+present.
+
+For convenience (and historical compatibility) the three
+most common quantifiers have single-character abbreviations:
+
+@table @code
+@item *
+is equivalent to @{0,@}
+
+@item +
+is equivalent to @{1,@}
+
+@item ?
+is equivalent to @{0,1@}
+@end table
+
+It is possible to construct infinite loops by following a
+subpattern that can match no characters with a quantifier
+that has no upper limit, for example:
+
+@example
+(a?)*
+@end example
+
+Earlier versions of Perl used to give an error at
+compile time for such patterns. However, because there are
+cases where this can be useful, such patterns are now
+accepted, but if any repetition of the subpattern does in
+fact match no characters, the loop is forcibly broken.
+
+@cindex Greedy regular expression matching
+@cindex Perl-style regular expressions, stingy repetitions
+By default, the quantifiers are @dfn{greedy} like in @sc{posix}
+mode, that is, they match as much as possible (up to the maximum
+number of permitted times), without causing the rest of the
+pattern to fail. The classic example of where this gives problems
+is in trying to match comments in C programs. These appear between
+the sequences @code{/*} and @code{*/} and within the sequence, individual
+@code{*} and @code{/} characters may appear. An attempt to match C
+comments by applying the pattern
+
+@example
+/\*.*\*/
+@end example
+
+@noindent
+to the string
+
+@example
+/* first command */ not comment /* second comment */
+@end example
+
+@noindent
+
+fails, because it matches the entire string owing to the
+greediness of the @code{.*} item.
+
+However, if a quantifier is followed by a question mark, it
+ceases to be greedy, and instead matches the minimum number
+of times possible, so the pattern @code{/\*.*?\*/}
+does the right thing with the C comments. The meaning of the
+various quantifiers is not otherwise changed, just the preferred
+number of matches.  Do not confuse this use of question
+mark with its use as a quantifier in its own right.
+Because it has two uses, it can sometimes appear doubled, as in
+
+@example
+\d??\d
+@end example
+
+which matches one digit by preference, but can match two if
+that is the only way the rest of the pattern matches.
+
+Note that greediness does not matter when specifying addresses,
+but can be nevertheless used to improve performance.
+
+@ignore
+If the PCRE_UNGREEDY option is set (an option which is not
+available in Perl), the quantifiers are not greedy by
+default, but individual ones can be made greedy by following
+them with a question mark. In other words, it inverts the
+default behaviour.
+@end ignore
+
+When a parenthesized subpattern is quantified with a minimum
+repeat count that is greater than 1 or with a limited maximum,
+more store is required for the compiled pattern, in
+proportion to the size of the minimum or maximum.
+
+@cindex Perl-style regular expressions, single line
+If a pattern starts with @code{.*} or @code{.@{0,@}} and the
+@code{S} modifier is used, the pattern is implicitly anchored,
+because whatever follows will be tried against every character
+position in the subject string, so there is no point in
+retrying the overall match at any position after the first.
+PCRE treats such a pattern as though it were preceded by \A.
+
+When a capturing subpattern is repeated, the value captured
+is the substring that matched the final iteration. For example,
+after
+
+@example
+(tweedle[dume]@{3@}\s*)+
+@end example
+
+@noindent
+has matched @samp{tweedledum tweedledee} the value of the
+captured substring is @samp{tweedledee}.  However, if there are
+nested capturing subpatterns, the corresponding captured
+values may have been set in previous iterations. For example,
+after
+
+@example
+/(a|(b))+/
+@end example
+
+matches @samp{aba}, the value of the second captured substring is
+@samp{b}.
+
+@node Backreferences
+@appendixsec Backreferences
+@cindex Perl-style regular expressions, backreferences
+
+Outside a character class, a backslash followed by a digit
+greater than 0 (and possibly further digits) is a back
+reference to a capturing subpattern earlier (i.e.  to its
+left) in the pattern, provided there have been that many
+previous capturing left parentheses.
+
+However, if the decimal number following the backslash is
+less than 10, it is always taken as a back reference, and
+causes an error only if there are not that many capturing
+left parentheses in the entire pattern. In other words, the
+parentheses that are referenced need not be to the left of
+the reference for numbers less than 10. @ref{Backslash}
+for further details of the handling of digits following a backslash.
+
+A back reference matches whatever actually matched the capturing
+subpattern in the current subject string, rather than
+anything matching the subpattern itself. So the pattern
+
+@example
+(sens|respons)e and \1ibility
+@end example
+
+@noindent
+matches @samp{sense and sensibility} and @samp{response and responsibility},
+but not @samp{sense and responsibility}. If caseful
+matching is in force at the time of the back reference, the
+case of letters is relevant. For example,
+
+@example
+((?i)blah)\s+\1
+@end example
+
+@noindent
+matches @samp{blah blah} and @samp{Blah Blah}, but not
+@samp{BLAH blah}, even though the original capturing
+subpattern is matched caselessly.
+
+There may be more than one back reference to the same subpattern.
+Also, if a subpattern has not actually been used in a
+particular match, any back references to it always fail. For
+example, the pattern
+
+@example
+(a|(bc))\2
+@end example
+
+@noindent
+always fails if it starts to match @samp{a} rather than
+@samp{bc}.  Because there may be up to 99 back references, all
+digits following the backslash are taken as part of a potential
+back reference number; this is different from what happens
+in @sc{posix} mode. If the pattern continues with a digit
+character, some delimiter must be used to terminate the back
+reference.  If the @code{X} modifier option is set, this can be
+whitespace.  Otherwise an empty comment can be used, or the
+following character can be expressed in hexadecimal or octal.
+Note that this applies only to the LHS pattern; it is
+not possible yet to specify more than 9 backreferences on the 
+RHS of the `s' command. 
+
+A back reference that occurs inside the parentheses to which
+it refers fails when the subpattern is first used, so, for
+example, @code{(a\1)} never matches.  However, such references
+can be useful inside repeated subpatterns. For example, the
+pattern
+
+@example
+(a|b\1)+
+@end example
+
+@noindent
+matches any number of @samp{a}s and also @samp{aba}, @samp{ababbaa},
+etc. At each iteration of the subpattern, the back reference matches
+the character string corresponding to the previous iteration.  In
+order for this to work, the pattern must be such that the first
+iteration does not need to match the back reference.  This can be
+done using alternation, as in the example above, or by a
+quantifier with a minimum of zero.
+
+@node Assertions
+@appendixsec Assertions
+@cindex Perl-style regular expressions, assertions
+@cindex Perl-style regular expressions, asserting subpatterns
+
+An assertion is a test on the characters following or
+preceding the current matching point that does not actually
+consume any characters. The simple assertions coded as @code{\b},
+@code{\B}, @code{\A}, @code{\Z}, @code{\z}, @code{^} and @code{$}
+are described above. More complicated assertions are coded as
+subpatterns.  There are two kinds: those that look ahead of the
+current position in the subject string, and those that look behind it.
+
+@cindex Perl-style regular expressions, lookahead subpatterns
+An assertion subpattern is matched in the normal way, except
+that it does not cause the current matching position to be
+changed. Lookahead assertions start with @code{(?=} for positive
+assertions and @code{(?!} for negative assertions. For example,
+
+@example
+\w+(?=;)
+@end example
+
+@noindent
+matches a word followed by a semicolon, but does not include
+the semicolon in the match, and
+
+@example
+foo(?!bar)
+@end example
+
+@noindent
+matches any occurrence of @samp{foo} that is not followed by
+@samp{bar}.
+
+Note that the apparently similar pattern
+
+@example
+(?!foo)bar
+@end example
+
+@noindent
+@cindex Perl-style regular expressions, lookbehind subpatterns
+finds any occurrence of @samp{bar} even if it is preceded by
+@samp{foo}, because the assertion @code{(?!foo)} is always true
+when the next three characters are @samp{bar}. A lookbehind
+assertion is needed to achieve this effect.
+Lookbehind assertions start with @code{(?<=} for positive
+assertions and @code{(?<!} for negative assertions. So,
+
+@example
+(?<!foo)bar
+@end example
+
+achieves the required effect of finding an occurrence of
+@samp{bar} that is not preceded by @samp{foo}. The contents of a
+lookbehind assertion are restricted
+such that all the strings it matches must have a fixed
+length.  However, if there are several alternatives, they do
+not all have to have the same fixed length.  This is an extension
+compared with Perl 5.005, which requires all branches to match
+the same length of string. Thus
+
+@example
+(?<=dogs|cats|)
+@end example
+
+@noindent
+is permitted, but the apparently equivalent regular expression
+
+@example
+(?<!dogs?|cats?)
+@end example
+
+@noindent
+causes an error at compile time. Branches that match different
+length strings are permitted only at the top level of
+a lookbehind assertion: an assertion such as
+
+@example
+(?<=ab(c|de))
+@end example
+
+@noindent
+is not permitted, because its single top-level branch can
+match two different lengths, but it is acceptable if rewritten
+to use two top-level branches:
+
+@example
+(?<=abc|abde)
+@end example
+
+All this is required because lookbehind assertions simply
+move the current position back by the alternative's fixed
+width and then try to match.  If there are
+insufficient characters before the current position, the
+match is deemed to fail.  Lookbehinds, in conjunction with
+non-backtracking subpatterns can be particularly useful for
+matching at the ends of strings; an example is given at the end
+of the section on non-backtracking subpatterns.
+
+Several assertions (of any sort) may occur in succession.
+For example,
+
+@example
+(?<=\d@{3@})(?<!999)foo
+@end example
+
+@noindent
+matches @samp{foo} preceded by three digits that are not @samp{999}.
+Notice that each of the assertions is applied independently
+at the same point in the subject string. First there is a
+check that the previous three characters are all digits, and
+then there is a check that the same three characters are not
+@samp{999}.  This pattern does not match @samp{foo} preceded by six
+characters, the first of which are digits and the last three
+of which are not @samp{999}.  For example, it doesn't match
+@samp{123abcfoo}. A pattern to do that is
+
+@example
+(?<=\d@{3@}...)(?<!999)foo
+@end example
+
+@noindent
+This time the first assertion looks at the preceding six
+characters, checking that the first three are digits, and
+then the second assertion checks that the preceding three
+characters are not @samp{999}.  Actually, assertions can be
+nested in any combination, so one can write this as 
+
+@example
+(?<=\d@{3@}(?!999)...)foo
+@end example
+
+or
+
+@example
+(?<=\d@{3@}...(?<!999))foo
+@end example
+
+@noindent
+both of which might be considered more readable.
+
+Assertion subpatterns are not capturing subpatterns, and may
+not be repeated, because it makes no sense to assert the
+same thing several times. If any kind of assertion contains
+capturing subpatterns within it, these are counted for the
+purposes of numbering the capturing subpatterns in the whole
+pattern.  However, substring capturing is carried out only
+for positive assertions, because it does not make sense for
+negative assertions.
+
+Assertions count towards the maximum of 200 parenthesized
+subpatterns.
+
+@node Non-backtracking subpatterns
+@appendixsec Non-backtracking subpatterns
+@cindex Perl-style regular expressions, non-backtracking subpatterns
+
+With both maximizing and minimizing repetition, failure of
+what follows normally causes the repeated item to be evaluated
+again to see if a different number of repeats allows the
+rest of the pattern to match. Sometimes it is useful to
+prevent this, either to change the nature of the match, or
+to cause it fail earlier than it otherwise might, when the
+author of the pattern knows there is no point in carrying
+on.
+
+Consider, for example, the pattern @code{\d+foo} when applied to
+the subject line
+
+@example
+123456bar
+@end example
+
+After matching all 6 digits and then failing to match @samp{foo},
+the normal action of the matcher is to try again with only 5
+digits matching the @code{\d+} item, and then with 4, and so on,
+before ultimately failing. Non-backtracking subpatterns
+provide the means for specifying that once a portion of the
+pattern has matched, it is not to be re-evaluated in this way,
+so the matcher would give up immediately on failing to match
+@samp{foo} the first time.  The notation is another kind of special
+parenthesis, starting with @code{(?>} as in this example:
+
+@example
+(?>\d+)bar
+@end example
+
+This kind of parenthesis ``locks up'' the part of the pattern
+it contains once it has matched, and a failure further into
+the pattern is prevented from backtracking into it.
+Backtracking past it to previous items, however, works as
+normal.
+
+Non-backtracking subpatterns are not capturing subpatterns.  Simple
+cases such as the above example can be thought of as a maximizing
+repeat that must swallow everything it can.  So,
+while both @code{\d+} and @code{\d+?} are prepared to adjust the number of
+digits they match in order to make the rest of the pattern
+match, @code{(?>\d+)} can only match an entire sequence of digits.
+
+This construction can of course contain arbitrarily complicated
+subpatterns, and it can be nested.
+
+@cindex Perl-style regular expressions, lookbehind subpatterns
+Non-backtracking subpatterns can be used in conjunction with look-behind
+assertions to specify efficient matching at the end
+of the subject string. Consider a simple pattern such as
+
+@example
+abcd$
+@end example
+
+@noindent
+when applied to a long string which does not match.  Because
+matching proceeds from left to right, @command{sed} will look for
+each @samp{a} in the subject and then see if what follows matches
+the rest of the pattern. If the pattern is specified as
+
+@example
+^.*abcd$
+@end example
+
+@noindent
+the initial @code{.*} matches the entire string at first, but when
+this fails (because there is no following @samp{a}), it backtracks
+to match all but the last character, then all but the
+last two characters, and so on. Once again the search for
+@samp{a} covers the entire string, from right to left, so we are
+no better off. However, if the pattern is written as
+
+@example
+^(?>.*)(?<=abcd)
+@end example
+
+there can be no backtracking for the .* item; it can match
+only the entire string. The subsequent lookbehind assertion
+does a single test on the last four characters. If it fails,
+the match fails immediately. For long strings, this approach
+makes a significant difference to the processing time.
+
+When a pattern contains an unlimited repeat inside a subpattern
+that can itself be repeated an unlimited number of
+times, the use of a once-only subpattern is the only way to
+avoid some failing matches taking a very long time
+indeed.@footnote{Actually, the matcher embedded in @value{SSED}
+tries to do something for this in the simplest cases,
+like @code{([^b]*b)*}.  These cases are actually quite
+common: they happen for example in a regular expression
+like @code{\/\*([^*]*\*)*\/} which matches C comments.}
+
+The pattern
+
+@example
+(\D+|<\d+>)*[!?]
+@end example
+
+([^0-9<]+<(\d+>)?)*[!?]
+
+@noindent
+matches an unlimited number of substrings that either consist
+of non-digits, or digits enclosed in angular brackets, followed by
+an exclamation or question mark. When it matches, it runs quickly.
+However, if it is applied to
+
+@example
+aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
+@end example
+
+@noindent
+it takes a long time before reporting failure.  This is
+because the string can be divided between the two repeats in
+a large number of ways, and all have to be tried.@footnote{The
+example used @code{[!?]} rather than a single character at the end,
+because both @value{SSED} and Perl have an optimization that allows
+for fast failure when a single character is used. They
+remember the last single character that is required for a
+match, and fail early if it is not present in the string.}
+
+If the pattern is changed to
+
+@example
+((?>\D+)|<\d+>)*[!?]
+@end example
+
+sequences of non-digits cannot be broken, and failure happens
+quickly.
+
+@node Conditional subpatterns
+@appendixsec Conditional subpatterns
+@cindex Perl-style regular expressions, conditional subpatterns
+
+It is possible to cause the matching process to obey a subpattern
+conditionally or to choose between two alternative
+subpatterns, depending on the result of an assertion, or
+whether a previous capturing subpattern matched or not. The
+two possible forms of conditional subpattern are
+
+@example
+(?(@var{condition})@var{yes-pattern})
+(?(@var{condition})@var{yes-pattern}|@var{no-pattern})
+@end example
+
+If the condition is satisfied, the yes-pattern is used; otherwise
+the no-pattern (if present) is used. If there are more than two
+alternatives in the subpattern, a compile-time error occurs.
+
+There are two kinds of condition. If the text between the
+parentheses consists of a sequence of digits, the condition
+is satisfied if the capturing subpattern of that number has
+previously matched.  The number must be greater than zero.
+Consider the following pattern, which contains non-significant
+white space to make it more readable (assume the @code{X} modifier)
+and to divide it into three parts for ease of discussion:
+
+@example
+( \( )?   [^()]+   (?(1) \) )
+@end example
+
+The first part matches an optional opening parenthesis, and
+if that character is present, sets it as the first captured
+substring. The second part matches one or more characters
+that are not parentheses. The third part is a conditional
+subpattern that tests whether the first set of parentheses
+matched or not.  If they did, that is, if subject started
+with an opening parenthesis, the condition is true, and so
+the yes-pattern is executed and a closing parenthesis is
+required. Otherwise, since no-pattern is not present, the
+subpattern matches nothing.  In other words, this pattern
+matches a sequence of non-parentheses, optionally enclosed
+in parentheses.
+
+@cindex Perl-style regular expressions, lookahead subpatterns
+If the condition is not a sequence of digits, it must be an
+assertion.  This may be a positive or negative lookahead or
+lookbehind assertion. Consider this pattern, again containing
+non-significant white space, and with the two alternatives
+on the second line:
+
+@example
+(?(?=...[a-z])
+   \d\d-[a-z]@{3@}-\d\d |
+   \d\d-\d\d-\d\d )
+@end example
+
+The condition is a positive lookahead assertion that matches
+a letter that is three characters away from the current point.
+If a letter is found, the subject is matched against the first
+alternative @samp{@var{dd}-@var{aaa}-@var{dd}} (where @var{aaa} are
+letters and @var{dd} are digits); otherwise it is matched against 
+the second alternative, @samp{@var{dd}-@var{dd}-@var{dd}}.
+
+
+@node Recursive patterns
+@appendixsec Recursive patterns
+@cindex Perl-style regular expressions, recursive patterns
+@cindex Perl-style regular expressions, recursion
+
+Consider the problem of matching a string in parentheses,
+allowing for unlimited nested parentheses. Without the use
+of recursion, the best that can be done is to use a pattern
+that matches up to some fixed depth of nesting. It is not
+possible to handle an arbitrary nesting depth. Perl 5.6 has
+provided an experimental facility that allows regular
+expressions to recurse (amongst other things). It does this
+by interpolating Perl code in the expression at run time,
+and the code can refer to the expression itself. A Perl pattern
+tern to solve the parentheses problem can be created like
+this:
+
+@example
+$re = qr@{\( (?: (?>[^()]+) | (?p@{$re@}) )* \)@}x;
+@end example
+
+The @code{(?p@{...@})} item interpolates Perl code at run time,
+and in this case refers recursively to the pattern in which it
+appears. Obviously, @command{sed} cannot support the interpolation of
+Perl code.  Instead, the special item @code{(?R)} is provided for
+the specific case of recursion. This pattern solves the
+parentheses problem (assume the @code{X} modifier option is used
+so that white space is ignored):
+
+@example
+\( ( (?>[^()]+) | (?R) )* \)
+@end example
+
+First it matches an opening parenthesis. Then it matches any
+number of substrings which can either be a sequence of
+non-parentheses, or a recursive match of the pattern itself
+(i.e. a correctly parenthesized substring). Finally there is
+a closing parenthesis.
+
+This particular example pattern contains nested unlimited
+repeats, and so the use of a non-backtracking subpattern for
+matching strings of non-parentheses is important when applying
+the pattern to strings that do not match. For example, when
+it is applied to
+
+@example
+(aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa()
+@end example
+
+it yields a ``no match'' response quickly. However, if a
+standard backtracking subpattern is not used, the match runs
+for a very long time indeed because there are so many different
+ways the @code{+} and @code{*} repeats can carve up the subject,
+and all have to be tested before failure can be reported.
+
+The values set for any capturing subpatterns are those from
+the outermost level of the recursion at which the subpattern
+value is set. If the pattern above is matched against
+
+@example
+(ab(cd)ef)
+@end example
+
+@noindent
+the value for the capturing parentheses is @samp{ef}, which is
+the last value taken on at the top level.
+
+@node Comments
+@appendixsec Comments
+@cindex Perl-style regular expressions, comments
+
+The sequence (?# marks the start of a comment which continues
+ues up to the next closing parenthesis. Nested parentheses
+are not permitted. The characters that make up a comment
+play no part in the pattern matching at all.
+
+@cindex Perl-style regular expressions, extended
+If the @code{X} modifier option is used, an unescaped @code{#} character
+outside a character class introduces a comment that continues
+up to the next newline character in the pattern.

+[DESCRIPTION]
+.ds sd \fIsed\fP
+.ds Sd \fISed\fP
+\*(Sd is a stream editor.
+A stream editor is used to perform basic text
+transformations on an input stream
+(a file or input from a pipeline).
+While in some ways similar to an editor which
+permits scripted edits (such as \fIed\fP),
+\*(sd works by making only one pass over the
+input(s), and is consequently more efficient.
+But it is \*(sd's ability to filter text in a pipeline
+which particularly distinguishes it from other types of
+editors.
+
+[COMMAND SYNOPSIS]
+This is just a brief synopsis of \*(sd commands to serve as
+a reminder to those who already know \*(sd;
+other documentation (such as the texinfo document)
+must be consulted for fuller descriptions.

+.TP
+.RI y/ source / dest /
+Transliterate the characters in the pattern space which appear in
+.I source
+to the corresponding character in

+.SH
+Addresses
+\*(Sd commands can be given with no addresses, in which
+case the command will be executed for all input lines;
+with one address, in which case the command will only be executed
+for input lines which match that address; or with two
+addresses, in which case the command will be executed
+for all input lines which match the inclusive range of
+lines starting from the first address and continuing to
+the second address.
+Three things to note about address ranges:
+the syntax is
+.IR addr1 , addr2
+(i.e., the addresses are separated by a comma);
+the line which
+.I addr1
+matched will always be accepted,
+even if
+.I addr2
+selects an earlier line;
+and if
+.I addr2
+is a
+.IR regexp ,
+it will not be tested against the line that
+.I addr1
+matched.
+.PP
+After the address (or address-range),
+and before the command, a
+.B !
+may be inserted,
+which specifies that the command shall only be
+executed if the address (or address-range) does
+.B not
+match.
+.PP
+The following address types are supported:
+.TP
+.I number
+Match only the specified line
+.IR number
+(which increments cumulatively across files, unless the
+.B -s
+option is specified on the command line).
+.TP
+.IR first ~ step
+Match every
+.IR step 'th
+line starting with line
+.IR first .
+For example, ``sed -n 1~2p'' will print all the odd-numbered lines in
+the input stream, and the address 2~5 will match every fifth line,
+starting with the second.
+.I first
+can be zero; in this case, \*(sd operates as if it were equal to
+.IR step .
+(This is an extension.)
+.TP
+$
+Match the last line.
+.TP
+.RI / regexp /
+Match lines matching the regular expression
+.IR regexp .
+.TP
+.BI \fR\e\fPc regexp c
+Match lines matching the regular expression
+.IR regexp .
+The
+.B c
+may be any character.
+.PP
+GNU \*(sd also supports some special 2-address forms:
+.TP
+.RI 0, addr2
+Start out in "matched first address" state, until
+.I addr2
+is found.
+This is similar to
+.RI 1, addr2 ,
+except that if
+.I addr2
+matches the very first line of input the
+.RI 0, addr2
+form will be at the end of its range, whereas the
+.RI 1, addr2
+form will still be at the beginning of its range.
+This works only when
+.I addr2
+is a regular expression.
+.TP
+.IR addr1 ,+ N
+Will match
+.I addr1
+and the
+.I N
+lines following
+.IR addr1 .
+.TP
+.IR addr1 ,~ N
+Will match
+.I addr1
+and the lines following
+.I addr1
+until the next line whose input line number is a multiple of
+.IR N .
+
+[REGULAR EXPRESSIONS]
+POSIX.2 BREs
+.I should
+be supported, but they aren't completely because of performance
+problems.
+The

+sequence in a regular expression matches the newline character,
+and similarly for

+.BR \et ,
+and other sequences.

+/* alloca.c -- allocate automatically reclaimed memory
+   (Mostly) portable public-domain implementation -- D A Gwyn
+
+   This implementation of the PWB library alloca function,
+   which is used to allocate space off the run-time stack so
+   that it is automatically reclaimed upon procedure exit,
+   was inspired by discussions with J. Q. Johnson of Cornell.
+   J.Otto Tennant <jot@cray.com> contributed the Cray support.
+
+   There are some preprocessor constants that can
+   be defined when compiling for your specific system, for
+   improved efficiency; however, the defaults should be okay.
+
+   The general concept of this implementation is to keep
+   track of all alloca-allocated blocks, and reclaim any
+   that are found to be deeper in the stack than the current
+   invocation.  This heuristic does not reclaim storage as
+   soon as it becomes invalid, but it will do so eventually.
+
+   As a special case, alloca(0) reclaims storage without
+   allocating any.  It is a good idea to use alloca(0) in
+   your main control loop, etc. to force garbage collection.  */

+    # - The environment variables LANG, LC_CTYPE, LC_ALL are not set by
+    #   the system; nl_langinfo(CODESET) returns "US-ASCII" in this case.
+    # - The documentation says:
+    #     "... all code that calls BSD system routines should ensure
+    #      that the const *char parameters of these routines are in UTF-8
+    #      encoding. All BSD system functions expect their string
+    #      parameters to be in UTF-8 encoding and nothing else."
+    #   It also says
+    #     "An additional caveat is that string parameters for files,
+    #      paths, and other file-system entities must be in canonical
+    #      UTF-8. In a canonical UTF-8 Unicode string, all decomposable
+    #      characters are decomposed ..."
+    #   but this is not true: You can pass non-decomposed UTF-8 strings
+    #   to file system functions, and it is the OS which will convert
+    #   them to decomposed UTF-8 before accessing the file system.
+    # - The Apple Terminal application displays UTF-8 by default.
+    # - However, other applications are free to use different encodings:
+    #   - xterm uses ISO-8859-1 by default.
+    #   - TextEdit uses MacRoman by default.
+    # We prefer UTF-8 over decomposed UTF-8-MAC because one should
+    # minimize the use of decomposed Unicode. Unfortunately, through the
+    # Darwin file system, decomposed UTF-8 strings are leaked into user
+    # space nevertheless.
+    # Then there are also the locales with encodings other than US-ASCII

+/* Scan elements of ARGV (whose length is ARGC) for option characters
+   given in OPTSTRING.
+
+   If an element of ARGV starts with '-', and is not exactly "-" or "--",
+   then it is an option element.  The characters of this element
+   (aside from the initial '-') are option characters.  If 'getopt'
+   is called repeatedly, it returns successively each of the option characters
+   from each of the option elements.
+
+   If 'getopt' finds another option character, it returns that character,
+   updating 'optind' and 'nextchar' so that the next call to 'getopt' can
+   resume the scan with the following option character or ARGV-element.
+
+   If there are no more option characters, 'getopt' returns -1.
+   Then 'optind' is the index in ARGV of the first ARGV-element
+   that is not an option.  (The ARGV-elements have been permuted
+   so that those that are not options now come last.)
+
+   OPTSTRING is a string containing the legitimate option characters.
+   If an option character is seen that is not listed in OPTSTRING,
+   return '?' after printing an error message.  If you set 'opterr' to
+   zero, the error message is suppressed but we still return '?'.
+
+   If a char in OPTSTRING is followed by a colon, that means it wants an arg,
+   so the following text in the same ARGV-element, or the text of the following
+   ARGV-element, is returned in 'optarg'.  Two colons mean an option that
+   wants an optional arg; if there is text in the current ARGV-element,
+   it is returned in 'optarg', otherwise 'optarg' is set to zero.
+
+   If OPTSTRING starts with '-' or '+', it requests different methods of
+   handling the non-option ARGV-elements.
+   See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
+
+   Long-named options begin with '--' instead of '-'.
+   Their names may be abbreviated as long as the abbreviation is unique
+   or is an exact match for some defined option.  If they have an
+   argument, it follows the option name in the same ARGV-element, separated
+   from the option name by a '=', or else the in next ARGV-element.
+   When 'getopt' finds a long-named option, it returns 0 if that option's
+   'flag' field is nonzero, the value of the option's 'val' field
+   if the 'flag' field is zero.
+
+   The elements of ARGV aren't really const, because we permute them.
+   But we pretend they're const in the prototype to be compatible
+   with other systems.
+
+   LONGOPTS is a vector of 'struct option' terminated by an
+   element containing a name which is zero.
+
+   LONGIND returns the index in LONGOPT of the long-named option found.
+   It is only valid when a long-named option has been found by the most
+   recent call.
+
+   If LONG_ONLY is nonzero, '-' as well as '--' can introduce
+   long-named options.  */

+   If the caller did not specify anything,
+   the default is REQUIRE_ORDER if the environment variable

+
+   REQUIRE_ORDER means don't recognize them as options;
+   stop option processing when the first non-option is seen.
+   This is what Unix does.
+   This mode of operation is selected by either setting the environment
+   variable POSIXLY_CORRECT, or using '+' as the first character

+
+   PERMUTE is the default.  We permute the contents of ARGV as we

+   This allows options to be given in any order, even with programs

+
+   RETURN_IN_ORDER is an option available to programs that were
+   written to expect options and other ARGV-elements in any order
+   and that care about the ordering of the two.  We describe each
+   non-option ARGV-element as if it were the argument of an option
+   with character code 1.  Using '-' as the first character of the
+   list of option characters selects this mode of operation.
+
+   The special argument '--' forces an end of option-scanning regardless

+     with repeated_c.  This reduces the task to testing whether *any of the
+     four* bytes in longword1 is zero.
+
+     We compute tmp =
+       ((longword1 - repeated_one) & ~longword1) & (repeated_one << 7).
+     That is, we perform the following operations:
+       1. Subtract repeated_one.
+       2. & ~longword1.
+       3. & a mask consisting of 0x80 in every byte.
+     Consider what happens in each byte:
+       - If a byte of longword1 is zero, step 1 and 2 transform it into 0xff,
+         and step 3 transforms it into 0x80.  A carry can also be propagated
+         to more significant bytes.
+       - If a byte of longword1 is nonzero, let its lowest 1 bit be at
+         position k (0 <= k <= 7); so the lowest k bits are 0.  After step 1,
+         the byte ends in a single bit of value 0 and k bits of value 1.
+         After step 2, the result is just k bits of value 1: 2^k - 1.  After
+         step 3, the result is 0.  And no carry is produced.
+     So, if longword1 has only non-zero bytes, tmp is zero.
+     Whereas if longword1 has a zero byte, call j the position of the least
+     significant zero byte.  Then the result has a zero at positions 0, ...,
+     j-1 and a 0x80 at position j.  We cannot predict the result at the more
+     significant bytes (positions j+1..3), but it does not matter since we
+     already have a non-zero bit at position 8*j+7.
+
+     So, the test whether any byte in longword1 is zero is equivalent to

+
+/* Summary:
+
+All the apparent functions defined here are macros. The idea
+is that you would use these pre-tested macros to solve a
+very specific set of problems, and they would run fast.
+Caution: no side-effects in arguments please!! They may be
+evaluated MANY times!!
+
+These macros operate a stack of objects.  Each object starts life
+small, and may grow to maturity.  (Consider building a word syllable
+by syllable.)  An object can move while it is growing.  Once it has
+been "finished" it never changes address again.  So the "top of the
+stack" is typically an immature growing object, while the rest of the
+stack is of mature, fixed size and fixed address objects.
+
+These routines grab large chunks of memory, using a function you
+supply, called 'obstack_chunk_alloc'.  On occasion, they free chunks,
+by calling 'obstack_chunk_free'.  You must define them and declare
+them before using any obstack macros.
+
+Each independent stack is represented by a 'struct obstack'.
+Each of the obstack macros expects a pointer to such a structure
+as the first argument.
+
+One motivation for this package is the problem of growing char strings
+in symbol tables.  Unless you are "fascist pig with a read-only mind"
+--Gosper's immortal quote from HAKMEM item 154, out of context--you
+would not like to put any arbitrary upper limit on the length of your
+symbols.
+
+In practice this often means you will build many short symbols and a
+few long symbols.  At the time you are reading a symbol you don't know
+how long it is.  One traditional method is to read a symbol into a
+buffer, realloc()ating the buffer every time you try to read a symbol
+that is longer than the buffer.  This is beaut, but you still will
+want to copy the symbol from the buffer to a more permanent
+symbol-table entry say about half the time.
+
+With obstacks, you can work differently.  Use one obstack for all symbol
+names.  As you read a symbol, grow the name in the obstack gradually.
+When the name is complete, finalize it.  Then, if the symbol exists already,
+free the newly read name.
+
+The way we do this is to take a large chunk, allocating memory from
+low addresses.  When you want to build a symbol in the chunk you just
+add chars above the current "high water mark" in the chunk.  When you
+have finished adding chars, because you got to the end of the symbol,
+you know how long the chars are, and you can create a new object.
+Mostly the chars will not burst over the highest address of the chunk,
+because you would typically expect a chunk to be (say) 100 times as
+long as an average object.
+
+In case that isn't clear, when we have enough chars to make up
+the object, THEY ARE ALREADY CONTIGUOUS IN THE CHUNK (guaranteed)
+so we just point to it where it lies.  No moving of chars is
+needed and this is the second win: potentially long strings need
+never be explicitly shuffled. Once an object is formed, it does not
+change its address during its lifetime.
+
+When the chars burst over a chunk boundary, we allocate a larger
+chunk, and then copy the partly formed object from the end of the old
+chunk to the beginning of the new larger chunk.  We then carry on
+accreting characters to the end of the object as we normally would.
+
+A special macro is provided to add a single char at a time to a
+growing object.  This allows the use of register variables, which
+break the ordinary 'growth' macro.
+
+Summary:
+        We allocate large chunks.
+        We carve out one object at a time from the current chunk.
+        Once carved, an object never moves.
+        We are free to append data of any size to the currently
+          growing object.
+        Exactly one object is growing in an obstack at any one time.
+        You can run one obstack per control block.
+        You may have as many control blocks as you dare.
+        Because of the way we do it, you can "unwind" an obstack
+          back to a previous state. (You may remove objects much
+          as you would with a stack.)

+
+   The former two functions operate on STRING with length LENGTH,
+   while the later two operate on concatenation of STRING1 and STRING2
+   with lengths LENGTH1 and LENGTH2, respectively.
+
+   re_match() matches the compiled pattern in BUFP against the string,
+   starting at index START.
+
+   re_search() first tries matching at index START, then it tries to match
+   starting from index START + 1, and so on.  The last start position tried
+   is START + RANGE.  (Thus RANGE = 0 forces re_search to operate the same
+   way as re_match().)
+
+   The parameter STOP of re_{match,search}_2 specifies that no match exceeding
+   the first STOP characters of the concatenation of the strings should be
+   concerned.
+
+   If REGS is not NULL, and BUFP->no_sub is not set, the offsets of the match
+   and all groups is stored in REGS.  (For the "_2" variants, the offsets are
+   computed relative to the concatenation, not relative to the individual
+   strings.)
+
+   On success, re_match* functions return the length of the match, re_search*
+   return the position of the start of the match.  Return value -1 means no

+
+   Programs that use <stdbool.h> should be aware of some limitations
+   and standards compliance issues.
+
+   Standards compliance:
+
+       - <stdbool.h> must be #included before 'bool', 'false', 'true'
+         can be used.
+
+       - You cannot assume that sizeof (bool) == 1.
+
+       - Programs should not undefine the macros bool, true, and false,
+         as C99 lists that as an "obsolescent feature".
+
+   Limitations of this substitute, when used in a C89 environment:
+
+       - <stdbool.h> must be #included before the '_Bool' type can be used.
+
+       - You cannot assume that _Bool is a typedef; it might be a macro.
+
+       - Bit-fields of type 'bool' are not supported.  Portable code
+         should use 'unsigned int foo : 1;' rather than 'bool foo : 1;'.
+
+       - In C99, casts and automatic conversions to '_Bool' or 'bool' are
+         performed in such a way that every nonzero value gets converted
+         to 'true', and zero gets converted to 'false'.  This doesn't work
+         with this substitute.  With this substitute, only the values 0 and 1
+         give the expected result when converted to _Bool' or 'bool'.
+
+       - C99 allows the use of (_Bool)0.0 in constant expressions, but
+         this substitute cannot always provide this property.
+
+   Also, it is suggested that programs use 'bool' rather than '_Bool';

+/* Set up the following warnings, based on which modules are in use.
+   GNU Coding Standards discourage the use of fseek, since it imposes
+   an arbitrary limitation on some 32-bit hosts.  Remember that the
+   fseek module depends on the fseeko module, so we only have three
+   cases to consider:
+
+   1. The developer is not using either module.  Issue a warning under
+   GNULIB_POSIXCHECK for both functions, to remind them that both
+   functions have bugs on some systems.  _GL_NO_LARGE_FILES has no
+   impact on this warning.
+
+   2. The developer is using both modules.  They may be unaware of the
+   arbitrary limitations of fseek, so issue a warning under
+   GNULIB_POSIXCHECK.  On the other hand, they may be using both
+   modules intentionally, so the developer can define
+   _GL_NO_LARGE_FILES in the compilation units where the use of fseek
+   is safe, to silence the warning.
+
+   3. The developer is using the fseeko module, but not fseek.  Gnulib
+   guarantees that fseek will still work around platform bugs in that
+   case, but we presume that the developer is aware of the pitfalls of
+   fseek and was trying to avoid it, so issue a warning even when
+   GNULIB_POSIXCHECK is undefined.  Again, _GL_NO_LARGE_FILES can be
+   defined to silence the warning in particular compilation units.
+   In C++ compilations with GNULIB_NAMESPACE, in order to avoid that
+   fseek gets defined as a macro, it is recommended that the developer
+   uses the fseek module, even if he is not calling the fseek function.
+
+   Most gnulib clients that perform stream operations should fall into
+   category 3.  */

+/* Each of these macros verifies that its argument R is nonzero.  To
+   be portable, R should be an integer constant expression.  Unlike
+   assert (R), there is no run-time overhead.
+
+   If _Static_assert works, verify (R) uses it directly.  Similarly,
+   _GL_VERIFY_TRUE works by packaging a _Static_assert inside a struct
+   that is an operand of sizeof.
+
+   The code below uses several ideas for C++ compilers, and for C
+   compilers that do not support _Static_assert:
+
+   * The first step is ((R) ? 1 : -1).  Given an expression R, of
+     integral or boolean or floating-point type, this yields an
+     expression of integral type, whose value is later verified to be
+     constant and nonnegative.
+
+   * Next this expression W is wrapped in a type
+     struct _gl_verify_type {
+       unsigned int _gl_verify_error_if_negative: W;
+     }.
+     If W is negative, this yields a compile-time error.  No compiler can
+     deal with a bit-field of negative size.
+
+     One might think that an array size check would have the same
+     effect, that is, that the type struct { unsigned int dummy[W]; }
+     would work as well.  However, inside a function, some compilers
+     (such as C++ compilers and GNU C) allow local parameters and
+     variables inside array size expressions.  With these compilers,
+     an array size check would not properly diagnose this misuse of
+     the verify macro:
+
+       void function (int n) { verify (n < 0); }
+
+   * For the verify macro, the struct _gl_verify_type will need to
+     somehow be embedded into a declaration.  To be portable, this
+     declaration must declare an object, a constant, a function, or a
+     typedef name.  If the declared entity uses the type directly,
+     such as in
+
+       struct dummy {...};
+       typedef struct {...} dummy;
+       extern struct {...} *dummy;
+       extern void dummy (struct {...} *);
+       extern struct {...} *dummy (void);
+
+     two uses of the verify macro would yield colliding declarations
+     if the entity names are not disambiguated.  A workaround is to
+     attach the current line number to the entity name:
+
+       #define _GL_CONCAT0(x, y) x##y
+       #define _GL_CONCAT(x, y) _GL_CONCAT0 (x, y)
+       extern struct {...} * _GL_CONCAT (dummy, __LINE__);
+
+     But this has the problem that two invocations of verify from
+     within the same macro would collide, since the __LINE__ value
+     would be the same for both invocations.  (The GCC __COUNTER__
+     macro solves this problem, but is not portable.)
+
+     A solution is to use the sizeof operator.  It yields a number,
+     getting rid of the identity of the type.  Declarations like
+
+       extern int dummy [sizeof (struct {...})];
+       extern void dummy (int [sizeof (struct {...})]);
+       extern int (*dummy (void)) [sizeof (struct {...})];
+
+     can be repeated.
+
+   * Should the implementation use a named struct or an unnamed struct?
+     Which of the following alternatives can be used?
+
+       extern int dummy [sizeof (struct {...})];
+       extern int dummy [sizeof (struct _gl_verify_type {...})];
+       extern void dummy (int [sizeof (struct {...})]);
+       extern void dummy (int [sizeof (struct _gl_verify_type {...})]);
+       extern int (*dummy (void)) [sizeof (struct {...})];
+       extern int (*dummy (void)) [sizeof (struct _gl_verify_type {...})];
+
+     In the second and sixth case, the struct type is exported to the
+     outer scope; two such declarations therefore collide.  GCC warns
+     about the first, third, and fourth cases.  So the only remaining
+     possibility is the fifth case:
+
+       extern int (*dummy (void)) [sizeof (struct {...})];
+
+   * GCC warns about duplicate declarations of the dummy function if
+     -Wredundant-decls is used.  GCC 4.3 and later have a builtin
+     __COUNTER__ macro that can let us generate unique identifiers for
+     each dummy function, to suppress this warning.
+
+   * This implementation exploits the fact that older versions of GCC,
+     which do not support _Static_assert, also do not warn about the
+     last declaration mentioned above.
+
+   * GCC warns if -Wnested-externs is enabled and verify() is used
+     within a function body; but inside a function, you can always
+     arrange to use verify_expr() instead.
+
+   * In C++, any struct definition inside sizeof is invalid.
+     Use a template type to work around the problem.  */

+

+
+   To have finer-grained control over the initial size, set *PN to a
+   nonzero value before calling this function with P == NULL.  For
+   example:
+
+     int *p = NULL;
+     size_t used = 0;
+     size_t allocated = 0;
+     size_t allocated1 = 1000;

+
+dnl Macro to add for using GNU gettext.
+
+dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
+dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The
+dnl    default (if it is not specified or empty) is 'no-libtool'.
+dnl    INTLSYMBOL should be 'external' for packages with no intl directory,
+dnl    and 'no-libtool' or 'use-libtool' for packages with an intl directory.
+dnl    If INTLSYMBOL is 'use-libtool', then a libtool library
+dnl    $(top_builddir)/intl/libintl.la will be created (shared and/or static,
+dnl    depending on --{enable,disable}-{shared,static} and on the presence of
+dnl    AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library
+dnl    $(top_builddir)/intl/libintl.a will be created.
+dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
+dnl    implementations (in libc or libintl) without the ngettext() function

+
+dnl Sets INCLUDE_NEXT and PRAGMA_SYSTEM_HEADER.
+dnl
+dnl INCLUDE_NEXT expands to 'include_next' if the compiler supports it, or to
+dnl 'include' otherwise.
+dnl
+dnl INCLUDE_NEXT_AS_FIRST_DIRECTIVE expands to 'include_next' if the compiler
+dnl supports it in the special case that it is the first include directive in
+dnl the given file, or to 'include' otherwise.
+dnl
+dnl PRAGMA_SYSTEM_HEADER can be used in files that contain #include_next,
+dnl so as to avoid GCC warnings when the gcc option -pedantic is used.
+dnl '#pragma GCC system_header' has the same effect as if the file was found
+dnl through the include search path specified with '-isystem' options (as
+dnl opposed to the search path specified with '-I' options). Namely, gcc
+dnl does not warn about some things, and on some systems (Solaris and Interix)
+dnl __STDC__ evaluates to 0 instead of to 1. The latter is an undesired side
+dnl effect; we are therefore careful to use 'defined __STDC__' or '1' instead
+dnl of plain '__STDC__'.
+dnl
+dnl PRAGMA_COLUMNS can be used in files that override system header files, so
+dnl as to avoid compilation errors on HP NonStop systems when the gnulib file
+dnl is included by a system header file that does a "#pragma COLUMNS 80" (which
+dnl has the effect of truncating the lines of that file and all files that it
+dnl includes to 80 columns) and the gnulib file has lines longer than 80

+dnl ------------
+dnl Tests for a multithreading library to be used.
+dnl If the configure.ac contains a definition of the gl_THREADLIB_DEFAULT_NO
+dnl (it must be placed before the invocation of gl_THREADLIB_EARLY!), then the
+dnl default is 'no', otherwise it is system dependent. In both cases, the user
+dnl can change the choice through the options --enable-threads=choice or
+dnl --disable-threads.
+dnl Defines at most one of the macros USE_POSIX_THREADS, USE_SOLARIS_THREADS,
+dnl USE_PTH_THREADS, USE_WINDOWS_THREADS
+dnl Sets the variables LIBTHREAD and LTLIBTHREAD to the linker options for use
+dnl in a Makefile (LIBTHREAD for use without libtool, LTLIBTHREAD for use with
+dnl libtool).
+dnl Sets the variables LIBMULTITHREAD and LTLIBMULTITHREAD similarly, for
+dnl programs that really need multithread functionality. The difference
+dnl between LIBTHREAD and LIBMULTITHREAD is that on platforms supporting weak
+dnl symbols, typically LIBTHREAD="" whereas LIBMULTITHREAD="-lpthread".
+dnl Adds to CPPFLAGS the flag -D_REENTRANT or -D_THREAD_SAFE if needed for
+dnl multithread-safe programs.

+; this file contains a script of tests to run through regress.exe
+;
+; comments start with a semicolon and proceed to the end of the line
+;
+; changes to regular expression compile flags start with a "-" as the first
+; non-whitespace character and consist of a list of the printable names
+; of the flags, for example "match_default"
+;
+; Other lines contain a test to perform using the current flag status
+; the first token contains the expression to compile, the second the string
+; to match it against. If the second string is "!" then the expression should
+; not compile, that is the first string is an invalid regular expression.
+; This is then followed by a list of integers that specify what should match,
+; each pair represents the starting and ending positions of a subexpression
+; starting with the zeroth subexpression (the whole match).
+; A value of -1 indicates that the subexpression should not take part in the
+; match at all, if the first value is -1 then no part of the expression should
+; match the string.
+;
+; Tests taken from BOOST testsuite and adapted to glibc regex.

+# regular expression test set
+# Lines are at least three fields, separated by one or more tabs.  "" stands
+# for an empty field.  First field is an RE.  Second field is flags.  If
+# C flag given, regcomp() is expected to fail, and the third field is the
+# error name (minus the leading REG_).
+#
+# Otherwise it is expected to succeed, and the third field is the string to
+# try matching it against.  If there is no fourth field, the match is
+# expected to fail.  If there is a fourth field, it is the substring that
+# the RE is expected to match.  If there is a fifth field, it is a comma-
+# separated list of what the subexpressions should match, with - indicating
+# no match for that one.  In both the fourth and fifth fields, a (sub)field
+# starting with @ indicates that the (sub)expression is expected to match
+# a null string followed by the stuff after the @; this provides a way to
+# test where null strings match.  The character `N' in REs and strings
+# is newline, `S' is space, `T' is tab, `Z' is NUL.
+#

+#  dc.sed - an arbitrary precision RPN calculator
+#  Created by Greg Ubben <gsu@romulus.ncsc.mil> early 1995, late 1996
+#
+#  Dedicated to MAC's memory of the IBM 1620 ("CADET") computer.
+#  @(#)GSU dc.sed 1.1 06-Mar-1999 [non-explanatory]
+#
+#  Examples:
+#	sqrt(2) to 10 digits:	echo "10k 2vp" | dc.sed
+#	20 factorial:		echo "[d1-d1<!*]s! 20l!xp" | dc.sed
+#	sin(ln(7)):		echo "s(l(7))" | bc -c /usr/lib/lib.b | dc.sed
+#	hex to base 60:		echo "60o16i 6B407.CAFE p" | dc.sed
+#	tests most of dc.sed:	echo 16oAk2vp | dc.sed
+#
+#  To debug or analyze, give the dc Y command as input or add it to
+#  embedded dc routines, or add the sed p command to the beginning of
+#  the main loop or at various points in the low-level sed routines.
+#  If you need to allow [|~] characters in the input, filter this
+#  script through "tr '|~' '\36\37'" first (or use dc.pl).
+#
+#  Not implemented:	! \
+#  But implemented:	K Y t # !< !> != fractional-bases
+#  SunOS limits:	199/199 commands (though could pack in 10-20 more)
+#  Limitations:		scale <= 999; |obase| >= 1; input digits in [0..F]
+#  Completed:		1am Feb 4, 1997

+A dialogue on poverty
+2
+
+3
+        On the night when the rain beats,
+4
+        Driven by the wind,
+5
+        On the night when the snowflakes mingle
+6
+        With a sleety rain,
+7
+        I feel so helplessly cold.
+8
+        I nibble at a lump of salt,
+9
+        Sip the hot, oft-diluted dregs of _sake_;
+10
+        And coughing, snuffling,
+11
+        And stroking my scanty beard,
+12
+        I say in my pride,
+13
+        "There's none worthy, save I!"
+14
+        But I shiver still with cold.
+15
+        I pull up my hempen bedclothes,
+16
+        Wear what few sleeveless clothes I have,
+17
+        But cold and bitter is the night!
+18
+        As for those poorer than myself,        
+19
+        Their parents must be cold and hungry,
+20
+        Their wives and children beg and cry.
+21
+        Then, how do you struggle through life?
+22
+        
+23
+        Wide as they call the heaven and earth,
+24
+        For me they have shrunk quite small;
+25
+        Bright though they call the sun and moon,
+26
+        They never shine for me.
+27
+        Is it the same with all men,
+28
+        Or for me alone?
+29
+        By rare chance I was born a man
+30
+        And no meaner than my fellows,
+31
+        But, wearing unwadded sleeveless clothes
+32
+        In tatters, like weeds waving in the sea,
+33
+        Hanging from my shoulders,
+34
+        And under the sunken roof,
+35
+        Within the leaning walls,
+36
+        Here I lie on straw
+37
+        Spread on bare earth,
+38
+        With my parents at my pillow,
+39
+        And my wife and children at my feet,
+40
+        All huddled in grief and tears.
+41
+        No fire sends up smoke
+42
+        At the cooking-place,
+43
+        And in the cauldron
+44
+        A spider spins its web.
+45
+        With not a grain to cook,
+46
+        We moan like the night thrush.
+47
+        Then, "to cut," as the saying is,
+48
+        "The ends of what is already too short,"
+49
+        The village headman comes,
+50
+        With rod in hand, to our sleeping place,
+51
+        Growling for his dues.
+52
+        Must it be so hopeless --
+53
+        The way of this world?

+The girl on the summit of the load sat motionless, surrounded by tables and chairs with their legs upwards, backed by an oak settle, and ornamented in front by pots of geraniums, myrtles, and cactuses, together with a caged canary -- all probably from the windows of the house just vacated.  There was also a cat in a willow basket, from the partly-opened lid of which she gazed with half-closed eyes, and affectionately-surveyed the small birds around.  The handsome girl waited for some time idly in her place, and the only sound heard in the stillness was the hopping of the canary up and down the perches of its prison.  Then she looked attentively downwards.  It was not at the bird, nor at the cat; it was at an oblong package tied in paper, and lying between them.  She turned her head to learn if the waggoner were coming.  He was not yet in sight; and her eyes crept back to the package, her thoughts seeming to run upon what was inside it.  At length she drew the article into her lap, and untied the paper covering; a small swing looking- glass was disclosed, in which she proceeded to survey herself attentively.  She parted her lips and smiled.  It was a fine morning, and the sun lighted up to a scarlet glow the crimson jacket she wore, and painted a soft lustre upon her bright face and dark hair.  The myrtles, geraniums, and cactuses packed around her were fresh and green, and at such a leafless season they invested the whole concern of horses, waggon, furniture, and girl with a peculiar vernal charm.  What possessed her to indulge in such a performance in the sight of the sparrows, blackbirds, and unperceived farmer who were alone its spectators, -- whether the smile began as a factitious one, to test her capacity in that art, -- nobody knows; it ended certainly in a real smile.  She blushed at herself, and seeing her reflection blush, blushed the more.  The change from the customary spot and necessary occasion of such an act -- from the dressing hour in a bedroom to a time of travelling out of doors -- lent to the idle deed a novelty it did not intrinsically possess.  The picture was a delicate one.  Woman's prescriptive infirmity had stalked into the sunlight, which had clothed it in the freshness of an originality.  A cynical inference was irresistible by Gabriel Oak as he regarded the scene, generous though he fain would have been.  There was no necessity whatever for her looking in the glass.  She did not adjust her hat, or pat her hair, or press a dimple into shape, or do one thing to signify that any such intention had been her motive in taking up the glass.  She simply observed herself as a fair product of Nature in the feminine kind, her thoughts seeming to glide into far-off though likely dramas in which men would play a part -- vistas of probable triumphs -- the smiles being of a phase suggesting that hearts were imagined as lost and won.  Still, this was but conjecture, and the whole series of actions was so idly put forth as to make it rash to assert that intention had any part in them at all.  The waggoner's steps were heard returning.  She put the glass in the paper, and the whole again into its place.  When the waggon had passed on, Gabriel withdrew from his point of espial, and descending into the road, followed the vehicle to the turnpike-gate some way beyond the bottom of the hill, where the object of his contemplation now halted for the payment of toll.  About twenty steps still remained between him and the gate, when he heard a dispute.  It was a difference concerning twopence between the persons with the waggon and the man at the toll-bar.  "Mis'ess's niece is upon the top of the things, and she says that's enough that I've offered ye, you great miser, and she won't pay any more."  These were the waggoner's words.  "Very well; then mis'ess's niece can't pass," said the turnpike-keeper, closing the gate.  Oak looked from one to the other of the disputants, and fell into a reverie.  There was something in the tone of twopence remarkably insignificant.  Threepence had a definite value as money -- it was an appreciable infringement on a day's wages, and, as such, a higgling matter; but twopence -- "Here," he said, stepping forward and handing twopence to the gatekeeper; "let the young woman pass."  He looked up at her then; she heard his words, and looked down.  Gabriel's features adhered throughout their form so exactly to the middle line between the beauty of St. John and the ugliness of Judas Iscariot, as represented in a window of the church he attended, that not a single lineament could be selected and called worthy either of distinction or notoriety.  The red-jacketed and dark-haired maiden seemed to think so too, for she carelessly glanced over him, and told her man to drive on.  She might have looked her thanks to Gabriel on a minute scale, but she did not speak them; more probably she felt none, for in gaining her a passage he had lost her her point, and we know how women take a favour of that kind.  The gatekeeper surveyed the retreating vehicle.  "That's a handsome maid," he said to Oak.  "But she has her faults," said Gabriel.  "True, farmer." "And the greatest of them is -- well, what it is always." "Beating people down? ay, 'tis so." "O no." "What, then?" Gabriel, perhaps a little piqued by the comely traveller's indifference, glanced back to where he had witnessed her performance over the hedge, and said, "Vanity, dude."

+The girl on the summit of the load sat motionless, surrounded by tables and chairs with their legs upwards, backed by an oak settle, and ornamented in front by pots of geraniums, myrtles, and cactuses, together with a caged canary -- all probably from the windows of the house just vacated.  There was also a cat in a willow basket, from the partly-opened lid of which she gazed with half-closed eyes, and affectionately-surveyed the small birds around.  The handsome girl waited for some time idly in her place, and the only sound heard in the stillness was the hopping of the canary up and down the perches of its prison.  Then she looked attentively downwards.  It was not at the bird, nor at the cat; it was at an oblong package tied in paper, and lying between them.  She turned her head to learn if the waggoner were coming.  He was not yet in sight; and her eyes crept back to the package, her thoughts seeming to run upon what was inside it.  At length she drew the article into her lap, and untied the paper covering; a small swing looking- glass was disclosed, in which she proceeded to survey herself attentively.  She parted her lips and smiled.  It was a fine morning, and the sun lighted up to a scarlet glow the crimson jacket she wore, and painted a soft lustre upon her bright face and dark hair.  The myrtles, geraniums, and cactuses packed around her were fresh and green, and at such a leafless season they invested the whole concern of horses, waggon, furniture, and girl with a peculiar vernal charm.  What possessed her to indulge in such a performance in the sight of the sparrows, blackbirds, and unperceived farmer who were alone its spectators, -- whether the smile began as a factitious one, to test her capacity in that art, -- nobody knows; it ended certainly in a real smile.  She blushed at herself, and seeing her reflection blush, blushed the more.
