[Zope] Design Patterns

[Ben Ocean]

Hi;
I'm new to Zope and Design Patterns, but I notice some wonderful 
similarities between the two. Can someone please help me to understand 
which design patterns Zope has laid into its architecture and where? The 
reason for my question is specifically because of the *Factory* method. Is 
this a straight *Factory Method* as outlined in the GoF book, or is it an 
*Abstract Factory*? Are Abstract Factories built into Zope's architecture? 
How about other creational methods, such as Prototype and Builder? How 
about Behavioral Methods and Structural Methods?
TIA,
BenO
