I dont seem to have this in my Zope Help System. Where can I obtain this? I
have 2 items in the Contents tab frame: ZeopTutorial and ZopeHelp. The API
Documentation I have is very sparse.

But what I need to know is what properties does the derivation give the new
object and how does the order affect its behaviour.
