[ZPT] Trying to understand ZPT

[Tamir Halperin]

I'm still learning zope but I'm currently looking for something specific =
to help me along. I'm still having a hard time understanding the =
difference between ZPT and DTML. Specifically, is there a document that =
discusses why we weren't satisfied with DTML and had to introduce ZPT? =
Where can I read about the practical implmentation decisioning and trade =
off analysis of ZPT over DTML and vice versa?
