Yeah, the file is just a class.  So if I put this line in the file:

m = mp3info()

Then I could import m?

Yeah, that's what I'm working on...  I was trying to do it with ZClasses, to
make dealing with the property sheets easier, but I kinda figured out how to
do that in python, so I'm just doing the whole thing in python.

I'm sure I'll have lots more questions before I'm done :)
