Getting a list of classes in the current module/auto introspection

[Andy Leszczynski]

Hi,
I have a following problem. Let's say there is a module which could be 
imported or run as __main__. It is going to contain hundreds of classes, 
something like that:

import moduleA
from moduleB import *

class A:
	pass

class B:
	pass

class C:
	pass

[...]


I would like to be able to get references (or names) of all of them but 
excluding stuff from moduleA and module B. Is there any pythonic/elegant 
way to do that?

Thanks, Andy
