"""

|
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.
