[Zope-CMF] CMF-ifying working Zope products

[Jeff Kowalczyk]

I have a few simple experimental Zope products, filesystem based. They
were mainly for experimenting with the possibilities of mxmRelations.

Now I'd like to extend those products into ZPT-skinned CMF Content
Types, so I could have a version that will work under CMF, with the
intention of learing DCWorkflow.

Is there a recommended sample for a CMF Content Type that will derive
from an existing Zope product, so I don't maintain parallel development
versions? I seem to recall one image type product was written this way,
but I don't know if that product passed out of existence over time.
