  yes, i finally twigged to that, but is there a *preferred* style?
from what i've seen, if there is a pair of files for a python module:

  * foo.bb (which includes ...)
  * foo.inc

the common style seems to be that:

  * foo.bb inherits setuptools, while
  * foo.inc inherits pypi (if necessary, of course)

at least i think that was the common style. obviously, there are
perfectly acceptable variations, i'd just like to know if there is a
recommended style.
