[Zope-CMF] CMFizing product?

[Rene Pijlman]

I'm about to develop a Python-based product which introduces new
content types and I'm wondering if I should make it pure Zope or
CMFized.

Is there any documentation on developing CMFized products? What
are the minimal requirements to integrate with CMF? Any good
examples?

Also, what are the relative merits of implementing my content
type as a CMF-type (using the type tool?) vs. a ZClass or Python
class?

TIA,
