[Zope3-checkins] CVS: Zope3/src/zope/app/form - __init__.py:1.3 widget.py:NONE

[Philipp von Weitershausen]

Update of /cvs-repository/Zope3/src/zope/app/form
In directory cvs.zope.org:/tmp/cvs-serv22177/src/zope/app/form

Modified Files:
	__init__.py 
Removed Files:
	widget.py 
Log Message:
The zope.app.form.widget module becomes zope.app.form. This makes sense
since widgets is really the only thing this package contains and it
shortens import paths.
