[Zope3-checkins] CVS: Zope3/src/zope/app/cache/interfaces - __init__.py:1.4

[Stephan Richter]

Update of /cvs-repository/Zope3/src/zope/app/cache/interfaces
In directory cvs.zope.org:/tmp/cvs-serv2886/src/zope/app/cache/interfaces

Modified Files:
	__init__.py 
Log Message:


Removed the caching service. It was not providing much value anyways, so it was
easy.



Also, I updated the views in a way that SQL Script's chace support would work
again.



There is still much to do:



- zope.app.cache.caching does not have a formally defined API (interface)



- The CacheName field should be a vocabulary field.



- Views need to be updated to current form.
