<snip a bunch about binpkg>

I think a key thing that is missing is build info that is only kept on
the installed system. If we were to ever create a build server setup, we
need to be able to have multiple binpkg's of the same version depending
on differences between sub-arch, use flags, cflag differences, gcc
version differences, etc. The key one i'm after is use flags. I'm not
sure of the technical details behind it, but we need something to make
the binpkgs more useful outside of the local system. Having the ebuild
packed at the end is a great idea! I think its just time to extend the
format to include more and possibly add things for build servers.
