[Zope] adding dtml/zpt methods to product classes

[Keith Alperin]

You understood the question perfectly; this is exactly what i was 
looking for.  I'm not sure where I got the idea of making those methods 
instance variables, but once I started, I never even looked for a 
better (even standard!) alternative.  Thank you (and Pascal Peregrina 
who gave the same answer) for your help!!

Sincerely,
Keith Alperin
