Hmm...right: dynamic language, runtime binding.  It would go out and find
whether or not Module1.Module2 existed only when import was called.  Sorry,
my bad.  I am assuming, however, that the help function walks the directory
tree, or else I would not get output like this:

>>> import ModTest
>>> help(ModTest)
Help on package ModTest:

NAME
    ModTest

FILE
    /usr/local/lib/python2.4/site-packages/ModTest/__init__.py

PACKAGE CONTENTS
    AModule
    BModule
    CModule

Thanks for the clarification.
