[Zope3-checkins] CVS: Zope3/src/zope/modulealias/tests - __init__.py:1.2 dummymodule.py:1.2 test_modulealias.py:1.2

[Chris McDonough]

Update of /cvs-repository/Zope3/src/zope/modulealias/tests
In directory cvs.zope.org:/tmp/cvs-serv5558/src/zope/modulealias/tests

Added Files:
	__init__.py dummymodule.py test_modulealias.py 
Log Message:
Merge security policy refactoring:

 - Moved all role- and grant-related functionality into
   zope.products.securitypolicy (and out of zope.app.security.grant).
   The zope.products.securitypolicy implementation is exactly
   the same as the old implementation; no changes were made
   to the actual mechanics of role-permission or principal-permission
   grants.  The only real difference is that all functionality
   that is the purview of what we want a security policy to have
   control of is now in that one place.

 - Created new modulealias directive which can be used to provide
   aliases to older modules (to not break existing ZODBs when
   module locations change).

 - Added minor feature: "make debug" launches a debug session in the
   spirit of Zope 2's "zopectl debug".
