[Distutils] Namespaces and setup.cfg

Heya! I recently moved all the setup.py configuration into setup.cfg for Pyroma. That worked very nicely. So I started doing it for my other packages, but with svn.path I failed. Everything *looked* fine, and I uploaded a 4.0 to PyPI, but if I install that in a virtualenv, importing svg or svg.path fails. The Python installation can't find them. Declaring them as a namespace means you can import them, but the imports are empty, there is no attributes to the modules, so you still can't use the package. Is this possible? And if so, how? Here's a link to the 4.0 release with all the info in the setup.cfg. https://github.com/regebro/svg.path/tree/5f941b729f0b7e3991f238776c9391d5791...
