I imagine things like libdir, prefix, datadir, docdir and other things
copied from autoconf. Where the defaults would be something like:
prefix = sys.prefix
libdir = sys.prefix/lib/pythonX.Y/site-packages/pkgname
datadir = sys.prefix/share/mypackage
docdir = sys.prefix/share/doc/mypackage

I don't see why moving all the metadata to egg-info would improve
things. You could easily(?) deprecate the `package_data' and
`data_files' keywords to setup() and replace them with `doc_files',
`data_files', `man_files', `config_files', etc. And depending on
which --sysconfdir, --datadir, etc options where used to setup.py
install_egg_info would write the correct values for datadir etc. The
runtime would then use your pkginfo.get_metadata() to find the files.
It might even be possible to do all of this inside distutils without
breaking backwards compatibility, just deprecating some keywords once
people start liking and using it.
