configure, build and file cleanup

["William Tyler" <wtyler at us dot ibm dot com>]

Hi all,
I would like to get familiar with the configuration and build system for
gcc.  I think that this would be a good place to start filtering out unused
files.
I think that I could also work on filling in the documentation in these
areas as well.  Does this seem like a reasonable aproach?

I hope that these questions are not too nubie like but here goes:
I have looked at the configure script and do not recognize it, where can I
get information on that is going on here (language, syntax and what not?)
Where can I get information on the make files and how they are processed?
Are the make files generated as output to from the configure script?

Thanks for the information folks.

Bill
