Resting Parrot: A sample distutils2 project
A sample project demonstrating how Python packaging works in a distutils2 world. Most of the interesting stuff is in setup.cfg, the rest is just stub Python modules and other files to match what is listed in setup.cfg.
The proposals here are from the PyCon 2010 packaging sprint: more details at http://wiki.python.org/moin/Distutils2.
There used to be an extras directory containing one file, sysconfig.cfg, that was not really part of the project sample, but relevant to distutils2 changes. It is now available in the distutils2 repository.
