[Jim Fulton]

Update of /cvs-repository/Zope3/src/zope/app/interfaces/services
In directory cvs.zope.org:/tmp/cvs-serv19468/src/zope/app/interfaces/services

Modified Files:
	configuration.py 
Log Message:
Got rid of some silly unused imports.

Refactored to get rid of some unneeded "Info" interfaces.

Added some missing documentation that queryConfigurationsFor and
createConfigurationsFor need to return wrapped objects.
