+# If these # comments don't work, trim them. Don't worry about any other
+# shell scripts, Configure will trim # comments from them for you.

+# (If you are trying to port this package to a machine without sh,
+# I would suggest you have a look at the prototypical config_h.SH file
+# and edit it to reflect your system. Some packages may include samples
+# of config.h for certain machines, so you might look for one of those.)

+# Yes, you may rip this off to use in other distribution packages. This
+# script belongs to the public domain and cannot be copyrighted.
+#
+# (Note: this Configure script was generated automatically. Rather than
+# working with this copy of Configure, you may wish to get metaconfig.
+# The dist-3.0 package (which contains metaconfig) was posted in
+# comp.sources.misc and is available on CPAN under authors/id/RAM so
+# you may fetch it yourself from your nearest archive site.)

+This installation shell script will examine your system and ask you questions
+to determine how the c2man package should be installed. If you get
+stuck on a question, you may use a ! shell escape to start a subshell or
+execute a command.  Many of the questions will have default answers in square
+brackets; typing carriage return will give you the default.
+
+On some of the questions which ask for file or directory names you are allowed
+to use the ~name construct to specify the login directory belonging to "name",
+even if you don't have a shell which knows about that.  Questions where this is
+allowed will be marked "(~name ok)".
+
+EOH
+	rp=''
+	dflt='Type carriage return to continue'
+	. ./myread
+	cat <<'EOH'
+
+The prompter used in this script allows you to use shell variables and
+backticks in your answers.  You may use $1, $2, etc...  to refer to the words
+in the default answer, as if the default line was a set of arguments given to a
+script shell.  This means you may also use $* to repeat the whole default line,
+so you do not have to re-type everything to add something to the default.
+
+Everytime there is a substitution, you will have to confirm.  If there is an
+error (e.g. an unmatched backtick), the default answer will remain unchanged
+and you will be prompted again.
+
+If you are in a hurry, you may run 'Configure -d'.  This will bypass nearly all
+the questions and use the computed defaults (or the previous answers if there
+was already a config.sh file). Type 'Configure -h' for a list of options.
+You may also start interactively and then answer '& -d' at any prompt to turn
+on the non-interactive behaviour for the remaining of the execution.
+
+EOH

+	cat <<EOH
+
+Much effort has been expended to ensure that this shell script will run on any
+Unix system.  If despite that it blows up on yours, your best bet is to edit
+Configure and run it again.  If you can't run Configure for some reason,
+you'll have to generate a config.sh file by hand.  Whatever problems you
+have, let me (srivasta@debian.org) know how I blew it.
+
+This installation script affects things in two ways:
+
+1) it may do direct variable substitutions on some of the files included
+   in this kit.
+2) it builds a config.h file for inclusion in C programs.  You may edit
+   any of these files as the need arises after running this script.
+
+If you make a mistake on a question, there is no easy way to back up to it
+currently.  The easiest thing to do is to edit config.sh and rerun all the SH
+files.  Configure will offer to let you do this before it runs the SH files.
