[Distutils] how can I egt the packages and modules in a distribution?

[Chris Withers]

Hi All,

Given a distribution name (ie: one of those things setuptools uses, 
'name' parameter to setup.py's setup call, etc) of a dsitrbution that 
has been installed with easy_install, buildout, pip, etc, how can I find 
out what python packages (ie: dotted names that I can import) are 
provided by that package?

I'm trying to write a scanner than looks for SQLAlchemy table objects 
and it would be great to be able to pass a distribution name rather than 
a set of dotted package names...

cheers,

Chris
