[Zope3-checkins] CVS: Zope3/lib/python/Zope/StartUp/tests - testSimpleRegistry.py:1.1

[Stephan Richter]

Update of /cvs-repository/Zope3/lib/python/Zope/StartUp/tests
In directory cvs.zope.org:/tmp/cvs-serv24805/lib/python/Zope/StartUp/tests

Added Files:
	testSimpleRegistry.py 
Log Message:
Okay, I finished the Forms work. Schema and Forms completely replace the
old Formulator code now. I have switched all the Content objects to using
Schema + Forms; especially the SQL Script has an interesting demo on how
to write your custom fields.

However, I am not satisfied with all my design decisions. There is still
a lot of work to be done in Converters and Widgets. Please contact Martijn
and/or me if you would like to help.
