In test.py there's currently a -T option that enables code coverage using the trace module. Are many people using it ? We'd like to work on including in test.py different coverage methods and outputs in Zope by making it interface with coverage.py from http://www.nedbatchelder.com/code/modules/coverage.html Anyone thinks it could be problematic ?
