[Zope-dev] how to create third party Product?

It would be great if someone can tell me how to create a third party product in 1) dtml, 2) python method. Does it depend on whether the product is a ZClass product? Where's the documentation that I can read to get a clue? thanks! __________________________________________________ Do You Yahoo!? Get personalized email addresses from Yahoo!
