Right.  There's no event hooking API in core Zope yet, just a small
number of hooks which meet specific requirements (e.g.
manage_beforeDelete and manage_afterAdd, which are useful for
catalogues).  As Sean mentioned, a good framework for doing this would
be the workflow tool in the CMF, but you'll find there's a lot to get to
grips with.  There's a workflow tool which allows you to set states and
transitions on objects; it also allows you to hook workflow to
particular object methods (by wrapping the method with a proxy class).
