Great!

The price of success is having to support the past.  CMF was in
development long before Page Templates were widely available,
and some folks are still using it without them (ZopeZen, for instance,
is / was DTML-based).

Therefore, we have two sets of skins, one DTML-based and the other
(primarily) ZPT based.  The ZPT skins depend on some features of the
DTML skins (the Python scripts, for instance) and override others (the
actual views).

For learning, I would focus on the ZPT versions, and look at the DTML
side only for reference.
