You mean, py2exe *has* problems with your code?

py2exe uses the standard Python's modulefinder.  If it has problems with
some code, it may be a bug.  Toby has simply overridden some methods, so
that dependencies are collected - that's what I also use, plus I format
a html page from the results.

Yes, that's the use case.  With the html page full of links, it's easy
to answer questions like
- why the hell is this module included?
- is that module really needed (for pure Python modules, the html page
has a link which show the .py file in the browser)

Anyway, I haven't yet looked at the module that Bob Ippolito has written
for py2app, maybe it works better than modulefinder, and it can be used
in the future for py2exe too.
