I have a module that has a tests/ directory which contains a C
extension that's only used by test cases. I don't want to install it.
I'm building it as a setuptools.Extension() added to setup() using the
ext_modules argument. The test directory is not added to setup's
packages argument. Even though none of the python sources from the
tests/ directory gets installed when running setup.py install, the
extension binary (and nothing else) is installed into
site-packages/tests/. How can I prohibit setuptools from doing it?
