[gentoo-soc] Ebuild Generator week 8 update

This week I continued working on the autoconf parser for the ebuild
generator. The project is on schedule.

Now I can parse the configure.ac files from both the xorg-server and the
"moc" project.
Sadly most of this week went into rewriting and planning as there were
quite a few corner cases that I didn't know could happen.
But with that out of the way I should be able to spend next week just
working with the information that the parser now outputs.

I think I had most of these problems because I don't really know shell
scripting and the autoconf docs seem to be written for more adept users.
So after looking at some shell scripting crash courses most of the
syntax in the autoconfigure files makes sense.

So for next week I hope I'll have the this structure working:
(top row is what files the ebuild generator parses)

configure.ac -→ Makefile.am -→ <source files provided by makefile.am>
   |               |                |
   v               v                v
 variables        sources,        includes
                  binaries,
                  etc

I will with the help off the varaibles that get defined in the configure
file guess the useflags for the project as they can pull in "EXTRA"
sources and/or add more binaries.
They will also come to use with the includes as they can be used to pull
in more/less includes.
I shall (as suggested) look for what variables that gets set with
AC_ARG_WITH and AC_ARG_ENABLE.

With all this information I hope I will be able to generate an ebuild
for a autotools project next week.
