[gentoo-soc] Ebuild Generator week 7

This week I began to work on implementing support for autotools in my
ebuild generator. I am now on schedule.

The first thing I did this week was to implement a basic automake parser
and I was pleasantly supprised that it was a lot easier to write and
interpret than the vanilla make files.
But that is probably why automake exists in the first place…

I then went on to write a autoconf parser.
That didn't went as smoothly as I wanted as you have to be really
careful in how you parse the files as you can mix in commands that
creates unbalanced parentheses or may screw with your parser in other
ways.
Thankfully they have quotation marks "[]" that you should wrap around
such cases.

Now I'm moving on to figure out how I should structure how the
program searches for possible useflag and/or optional dependecies.

I'm thinking about having it parse the makefile first and look for
variables that configure will supply to it in relevant areas.
Like variables that pull in stuff from EXTRA_…_SOURCES for example.
This way I can look for where those variables are defined in the
autoconf file and then just evaluate those parts of the autoconf file.

I don't know if this will make it easier or save me any time. But it
seems to me like it would be better if I could just evaluate those cases
as they use, as far as I've seen, the same autoconf macros/functions.
Which would mean that I can narrow down which macros I have to
implement.

I would really like some feedback on this as it could be a really really
bad idea.
