[Zope-dev] unregistering products

[alan milligan]

Hi,

We have a relatively common situation whereby we will create our own product 
by deriving off an existing Zope product.

However, the original product is still available through Products.meta_types 
and the factory construction mechanism.  This is a pain as then users must 
be careful as to what product's they create.

It is inconvenient to comment out the registerClass calls in the __init__.py 
to achieve this result.  Is there any other technique to deregister products 
yet still have them available in the PYTHONPATH to satisfy other 
dependencies?

Cheers, Alan
