[Zope3-checkins] CVS: Products3/demo/formatns - __init__.py:1.1 configure.zcml:1.1 interfaces.py:1.1

[Stephan Richter]

Update of /cvs-repository/Products3/demo/formatns
In directory cvs.zope.org:/tmp/cvs-serv14796

Added Files:
	__init__.py configure.zcml interfaces.py 
Log Message:
This is a demo product on how to develop your own TALES namespaces, which 
I imagine will be extremly useful. Furthermore, I think it is currently 
also the easiest way to extend Zope 3 in a very powerful way.

But please, do not misuse this feature!
