[TIP] Is there nose plugin for deeper discovery?

[Pete Forman]

I'd like to run nose at the top of a loosely organised collection of
python packages and individual files.

Say I have this directory structure.

a -\
   + b\
   |  +-foo.py
   |  +-test_foo.py
   +-c\
      +-bar.py
      +-test_bar.py
