[Zope3-checkins] CVS: Zope3 - test.py:1.19

[Jeremy Hylton]

Update of /cvs-repository/Zope3
In directory cvs.zope.org:/tmp/cvs-serv1854

Modified Files:
	test.py 
Log Message:
Add experimental -T option for code coverage with unit tests.

XXX This only works if trace.py is importable.  It lives in the Python
distribution's Tools/scripts directory and doesn't get installed
anywhere :-(.
