"""
Shared setup file for simple python packages. Uses a setup.cfg that
is the same as the distutils2 project, unless noted otherwise.
It exists for two reasons:
1) This makes it easier to reuse setup.py code between my own
projects
2) Easier migration to distutils2 when that catches on.
Additional functionality:
* Section metadata:
requires-test: Same as 'tests_require' option for setuptools.
