[Zope-dev] Python products

[Tom Deprez]

Hi,

I'm wondering, is there somewhere a simple example on how to create a python
product which behaves like the following ZClasses :

A simple zclass which contains some data (this is easy with the existing
examples)
A folder-like zclass which only allows to contain the simple zclass. (easy?)

A folder-like zclass which allows to contain the 2 above classes (probably
easy if I've an example of the 2de class)

Thanks in advance,

Tom.
