When you say it "works" I'm not sure what it is you are trying to do?
It seems that kmostly the classes are just containers representing
the file structure and mostly you could accomplish the same, more
simply, with os.walk?

Do the classes actually do anything? What exactly do you do with
a Product object? What is it for? Can you fill in a (virtual) CRC card
for each class?

Until we know what the cklasses are for its hard to know what you
want improved...
