The support for variables in the text-from-texi script is used to
automatically insert the current version of Window Maker, inherited from
the definition in the AC_INIT command, so it will be always correctly
updated without the need for hand work.
Having this version information is recommended by GNU texinfo because if
the document happens to get distributed outside a package it can help user
avoid problems.
The second use is to define a variable 'emailsupport' which contains the
email address of the development team, so we can also inherit it from the
AC_INIT setting.
The third use is for a special variable 'cctexi2txt' to differentiate
between texi2any and our script, because when using texi2any the title
page is not generated, so we need to duplicate some information in the
source, but we do not want it to appear twice in our generated doc.

The source of the documentation is in Texinfo format to have the
possibility someday to distribute in more format that just plain text;
There is a new Makefile to generate automatically the plain text file to be
distributed from the source; this doc is also generated by 'autogen.sh'
because a user would expect to find it before compiling the program, so
even before the 'configure' script have been generated, in the case he is
compiling from a git checkout;
There is a new script to generate the documentation, because from the way
we generate it we cannot assume that 'texi2any' is available and working
on the user's computer; it is also the opportunity to generate a better
looking document (see the description at the beginning of the script);
In this commit, the documentation only contains the base skeleton, it does
not contain yet any useful content because it is worth it's own commit.
