+Introduction
+************
+
+This is the README for `pv' ("Pipe Viewer"), a terminal-based tool for
+monitoring the progress of data through a pipeline.  It can be inserted into
+any normal pipeline between two processes to give a visual indication of how
+quickly data is passing through, how long it has taken, how near to
+completion it is, and an estimate of how long it will be until completion.
+
+
+Documentation
+*************
+
+A manual page is included in this distribution.  See `man ./doc/quickref.1',
+or `man pv' after installation.
+
+
+Compilation
+***********
+
+If you have downloaded `pv' from Subversion, first run "./generate.sh".
+
+To compile the package, type "sh ./configure", which should generate a
+Makefile for your system.  You may then type "make" to build everything.
+Note that GNU `make' is required; this may be installed as `gmake' on some
+systems, so if typing "make" gives an error, try "gmake" instead.
+
+See the file `doc/INSTALL' for more about the `configure' script.
+
+Developers note that you can do "./configure --enable-debugging" to cause
+debugging support to be built in, and "--enable-profiling" builds in
+profiling support (see "man gprof").  Also note that doing "make index" will
+generate an HTML code index (using "ctags" and "cproto"); this index lists
+all files used, all functions defined, and all TODOs marked in the code.
+
+Developers also note that the /* RATS */ comments are used to tell the RATS
+tool that a potential trouble spot has been checked so it doesn't need to
+warn about it. (RATS: Rough Auditing Tool for Security - home page
+http://www.fortifysoftware.com/security-resources/rats.jsp)

+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']

+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+			  [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.

+Basic Installation
+==================
+
+   These are generic installation instructions.
+
+   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, a file
+`config.cache' that saves the results of its tests to speed up
+reconfiguring, and a file `config.log' containing compiler output
+(useful mainly for debugging `configure').
+
+   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 at some point `config.cache'
+contains results you don't want to keep, you may remove or edit it.
+
+   The file `configure.in' is used to create `configure' by a program
+called `autoconf'.  You only need `configure.in' 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.  If you're
+     using `csh' on an old version of System V, you might need to type
+     `sh ./configure' instead to prevent `csh' from trying to execute
+     `configure' itself.
+
+     Running `configure' takes awhile.  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.
+
+  4. Type `make install' to install the programs and any data files and
+     documentation.
+
+  5. 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.
+
+Compilers and Options
+=====================
+
+   Some systems require unusual options for compilation or linking that
+the `configure' script does not know about.  You can give `configure'
+initial values for variables by setting them in the environment.  Using
+a Bourne-compatible shell, you can do that on the command line like
+this:
+     CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
+
+Or on systems that have the `env' program, you can do it like this:
+     env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
+
+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 must use a version of `make' that
+supports the `VPATH' variable, such as 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 `..'.
+
+   If you have to use a `make' that does not supports the `VPATH'
+variable, you have 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.
+
+Installation Names
+==================
+
+   By default, `make install' will install the package's files in
+`/usr/local/bin', `/usr/local/man', etc.  You can specify an
+installation prefix other than `/usr/local' by giving `configure' the
+option `--prefix=PATH'.
+
+   You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files.  If you
+give `configure' the option `--exec-prefix=PATH', the package will use
+PATH as the prefix for installing programs and libraries.
+Documentation and other data files will still use the regular prefix.
+
+   In addition, if you use an unusual directory layout you can give
+options like `--bindir=PATH' 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.
+
+   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'.
+
+Optional Features
+=================
+
+   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.
+
+Specifying the System Type
+==========================
+
+   There may be some features `configure' can not figure out
+automatically, but needs to determine by the type of host the package
+will run on.  Usually `configure' can figure that out, but if it prints
+a message saying it can not guess the host type, give it the
+`--host=TYPE' option.  TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name with three fields:
+     CPU-COMPANY-SYSTEM
+
+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 host type.
+
+   If you are building compiler tools for cross-compiling, you can also
+use the `--target=TYPE' option to select the type of system they will
+produce code for and the `--build=TYPE' option to select the type of
+system on which you are compiling the package.
+
+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.
+
+Operation Controls
+==================
+
+   `configure' recognizes the following options to control how it
+operates.
+
+`--cache-file=FILE'
+     Use and save the results of the tests in FILE instead of
+     `./config.cache'.  Set FILE to `/dev/null' to disable caching, for
+     debugging `configure'.
+
+`--help'
+     Print a summary of the options to `configure', and exit.
+
+`--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.
+
+`--version'
+     Print the version of Autoconf used to generate the `configure'
+     script, and exit.
+
+`configure' also accepts some other, not widely useful, options.

+.TH @UCPACKAGE@ 1 "June 2012" Linux "User Manuals"
+.SH NAME
+@PACKAGE@ \- monitor the progress of data through a pipe
+.SH SYNOPSIS
+.B @PACKAGE@
+[\fIOPTION\fR]
+[\fIFILE\fR]...
+.br
+.B @PACKAGE@
+[\fI\-h\fR|\fI\-V\fR]
+
+
+.SH DESCRIPTION
+.B @PACKAGE@
+allows a user to see the progress of data through a pipeline, by giving
+information such as time elapsed, percentage completed (with progress bar),
+current throughput rate, total data transferred, and ETA.
+
+To use it, insert it in a pipeline between two processes, with the
+appropriate options.  Its standard input will be passed through to its
+standard output and progress will be shown on standard error.
+
+.B @PACKAGE@
+will copy each supplied
+.B FILE
+in turn to standard output
+.BR "" "(" -
+means standard input), or if no
+.BR FILE s
+are specified just standard input is copied. This is the same behaviour
+as
+.BR cat (1).
+
+A simple example to watch how quickly a file is transferred using
+.BR nc (1):
+
+.RS
+.B @PACKAGE@ file | nc -w 1 somewhere.com 3000
+.RE
+
+A similar example, transferring a file from another process and passing the
+expected size to
+.BR @PACKAGE@ :
+
+.RS
+.B cat file | @PACKAGE@ -s 12345 | nc -w 1 somewhere.com 3000
+.RE
+
+A more complicated example using numeric output to feed into the
+.BR dialog (1)
+program for a full-screen progress display:
+ 
+.RS
+.B (tar cf - . \e
+.br
+.B " | @PACKAGE@ -n -s $(du -sb . | awk '{print $1}') \e"
+.br
+.B " | gzip -9 > out.tgz) 2>&1 \e"
+.br
+.B | dialog --gauge 'Progress' 7 70
+.RE
+
+Frequent use of this third form is not recommended as it may cause the
+programmer to overheat.
+
+
+.SH OPTIONS
+.B @PACKAGE@
+takes many options, which are divided into display switches, output
+modifiers, and general options.
+
+
+.SH DISPLAY SWITCHES
+If no display switches are specified,
+.B @PACKAGE@
+behaves as if
+.BR \-p ", " \-t ", " \-e ", " \-r ", and " \-b
+had been given (i.e. everything except average rate is switched on).
+Otherwise, only those display types that are explicitly switched on will be
+shown.
+.TP
+.B \-p, \-\-progress
+Turn the progress bar on.  If standard input is not a file and no
+size was given (with the
+.B \-s
+modifier), the progress bar cannot indicate how close to completion the
+transfer is, so it will just move left and right to indicate that data is
+moving.
+.TP
+.B \-t, \-\-timer
+Turn the timer on.  This will display the total elapsed time that
+.B @PACKAGE@
+has been running for.
+.TP
+.B \-e, \-\-eta
+Turn the ETA timer on.  This will attempt to guess, based on previous
+transfer rates and the total data size, how long it will be before
+completion.  This option will have no effect if the total data size cannot
+be determined.
+.TP
+.B \-r, \-\-rate
+Turn the rate counter on.  This will display the current rate of data
+transfer.
+.TP
+.B \-a, \-\-average\-rate
+Turn the average rate counter on.  This will display the average rate of
+data transfer so far.
+.TP
+.B \-b, \-\-bytes
+Turn the total byte counter on.  This will display the total amount of
+data transferred so far.
+.TP
+.B \-n, \-\-numeric
+Numeric output.  Instead of giving a visual indication of progress,
+.B @PACKAGE@
+will give an integer percentage, one per line, on standard error, suitable
+for piping (via convoluted redirection) into
+.BR dialog (1).
+Note that
+.B \-f
+is not required if
+.B \-n
+is being used.
+.TP
+.B \-q, \-\-quiet
+No output.  Useful if the
+.B \-L
+option is being used on its own to just limit the transfer rate of a pipe.
+
+
+.SH OUTPUT MODIFIERS
+.TP
+.B \-W, \-\-wait
+Wait until the first byte has been transferred before showing any progress
+information or calculating any ETAs.  Useful if the program you are piping to
+or from requires extra information before it starts, eg piping data into
+.BR gpg (1)
+or
+.BR mcrypt (1)
+which require a passphrase before data can be processed.
+.TP
+.B \-s SIZE, \-\-size SIZE
+Assume the total amount of data to be transferred is
+.B SIZE
+bytes when calculating percentages and ETAs.  The same suffixes of "k", "m"
+etc can be used as with
+.BR -L .
+.TP
+.B \-l, \-\-line\-mode
+Instead of counting bytes, count lines (newline characters). The progress
+bar will only move when a new line is found, and the value passed to the
+.B \-s
+option will be interpreted as a line count.
+.TP
+.B \-i SEC, \-\-interval SEC
+Wait
+.B SEC
+seconds between updates.  The default is to update every second.
+Note that this can be a decimal such as 0.1.
+.TP
+.B \-w WIDTH, \-\-width WIDTH
+Assume the terminal is
+.B WIDTH
+characters wide, instead of trying to work it out (or assuming 80 if it
+cannot be guessed).
+.TP
+.B \-H HEIGHT, \-\-height HEIGHT
+Assume the terminal is
+.B HEIGHT
+rows high, instead of trying to work it out (or assuming 25 if it
+cannot be guessed).
+.TP
+.B \-N NAME, \-\-name NAME
+Prefix the output information with
+.BR NAME .
+Useful in conjunction with
+.B \-c
+if you have a complicated pipeline and you want to be able to tell different
+parts of it apart.
+.TP
+.B \-f, \-\-force
+Force output.  Normally,
+.B @PACKAGE@
+will not output any visual display if standard error is not a terminal. 
+This option forces it to do so.
+.TP
+.B \-c, \-\-cursor
+Use cursor positioning escape sequences instead of just using carriage
+returns.  This is useful in conjunction with
+.B \-N
+(name) if you are using multiple
+.B @PACKAGE@
+invocations in a single, long, pipeline.
+
+
+.SH DATA TRANSFER MODIFIERS
+.TP
+.B \-L RATE, \-\-rate-limit RATE
+Limit the transfer to a maximum of
+.B RATE
+bytes per second.  A suffix of "k", "m", "g", or "t" can be added to denote
+kilobytes (*1024), megabytes, and so on.
+.TP
+.B \-B BYTES, \-\-buffer-size BYTES
+Use a transfer buffer size of
+.B BYTES
+bytes.  A suffix of "k", "m", "g", or "t" can be added to denote
+kilobytes (*1024), megabytes, and so on.  The default buffer size is the
+block size of the input file's filesystem multiplied by 32 (512kb max), or
+400kb if the block size cannot be determined.
+.TP
+.B \-R PID, \-\-remote PID
+If
+.B PID
+is an instance of
+.B @PACKAGE@
+that is already running,
+.B \-R PID
+will cause that instance to act as though it had been given
+this instance's command line instead.  For example, if
+.B @PACKAGE@ -L 123k
+is running with process ID 9876, then running
+.B @PACKAGE@ -R 9876 -L 321k
+will cause it to start using a rate limit of 321k instead of 123k.
+Note that some options cannot be changed while running, such as
+.BR \-c ,
+.BR \-l ,
+and
+.BR \-f .
+.TP
+.B ""
+.B NOTE:
+Specifying a
+.I PID
+that is not another
+.B @PACKAGE@
+process may cause that process to exit, because it will be sent a signal.
+
+.SH GENERAL OPTIONS
+.TP
+.B \-h, \-\-help
+Print a usage message on standard output and exit successfully.
+.TP
+.B \-V, \-\-version         
+Print version information on standard output and exit successfully.
+
+
+.SH EXIT STATUS
+An exit status of 1 indicates a problem with the
+.B \-R
+option.
+
+Any other exit status is a bitmask of the following:
+
+.TP
+.B 2
+One or more files could not be accessed, 
+.BR stat (2)ed,
+or opened.
+.TP
+.B 4
+An input file was the same as the output file.
+.TP
+.B 8
+Internal error with closing a file or moving to the next file.
+.TP
+.B 16
+There was an error while transferring data from one or more input files.
+.TP
+.B 32
+A signal was caught that caused an early exit.
+.TP
+.B 64
+Memory allocation failed.
+
+A zero exit status indicates no problems.

+%description
+PV ("Pipe Viewer") is a tool for monitoring the progress of data through a
+pipeline.  It can be inserted into any normal pipeline between two processes
+to give a visual indication of how quickly data is passing through, how long
+it has taken, how near to completion it is, and an estimate of how long it
+will be until completion.
