This let's configure set the correct version when the .spec file gets
created from the .spec.in file.  No more updating the version by hand!

Wow, that looks like hell, doesn't it?  It's actually really cool.  See,
each of those lines lists one of the packages that are required at
either install or build time.  Those wonderful things like
"@GTK_REQUIRED@" are just macros, defined in configure.in.
@GTK_REQUIRED@ is a replacement for the version of GTK+ that's required
in this release.  Nobody has to come in and mess with the spec file, the
program author just needs to change the version number in configure.in.
Pretty easy.  If we're watching cvs commits to these modules, we can see
when hackers add new dependancies, and we can put those into the spec
file.

Yeah, here's the version numbers I mentioned.  GTK+ seems to need 1.3.1,
as gnome-core is getting ported to the gtk+ 2 APIs and stuff.  

So, if we maintain the .spec files outside of their modules in CVS,
we've got to update all of this stuff by hand, instead of just having
the tools do the updating for us.  So, thoughts?  Anybody want to get
the debian/ directory for gnome-core current, so that we can all use it
as an example?  How about Solaris, FreeBSD, and Irix people?  Can you
take advantage of something similar?  Can we get your packaging files
into CVS?  (who else has packaging files that I've forgotten?)  Thanks!
