[Zope-CMF] How can I locate all CMF Products? **and** those based on ZPT?

[Jeffrey Franks]

Hi,

I remember a similar thread last week, but I'll ask it
with a different intent.

I would like to find all the CMF Products that are available.
There does not seem to be a central repository for them
(like the trove map on SF).

Also, I'm especially interested in those CMF Products that
are based on ZPT. I'm aware of only one -- ZMailman, but
there might be others.

How can I find this out?
