[Zope-Checkins] CVS: Zope3/lib/python/Zope/App/ComponentArchitecture/tests - testDirectives.py:1.1.2.5

[Jim Fulton]

Update of /cvs-repository/Zope3/lib/python/Zope/App/ComponentArchitecture/tests
In directory cvs.zope.org:/tmp/cvs-serv25226/lib/python/Zope/App/ComponentArchitecture/tests

Modified Files:
      Tag: Zope3InWonderland-branch
	testDirectives.py 
Log Message:
Added factory attribute to utility and service directives so that you
can specify a factory rather than an instance. This makes class source
files a little cleaner because they don't need to create an instance.

This is only useful when the instance can be created by calling the
factory without arguments.
