Update of /cvs-repository/Zope3
In directory cvs.zope.org:/tmp/cvs-serv5492

Modified Files:
	test.py

The test runner now follows symlinks.  This enables you to run unit and
functional tests for products that are checked out in a different CVS
sandbox and just symlinked from $ZOPE_3_SANDBOX_ROOT/src/zopeproducts.
