[Zope] overriding manage methods

[Robin Becker]

In my Z-Class I would like to hook various standard methods in a dtmlish
way.

The frame work would call my dtml method say manage_delObjects and
within that method I would like to call the original manage_delObjects.

I guess this must be a very standard requirement as I see that there are
methods called afterAdd and beforeDelete etc in the object manager. I
just don't know the proper namespace magic to override and eventually
call these.
