[Zope] Bug Tracker for Zope?

I was wondering if there was a Bugzilla-like product available for Zope. I have set up both Zope and Bugzilla, but this requires two separate authentication schemes. I haven't seen anything other than the Collector at Zope.org, but the code isn't available for it. Thanks. -- Guy Davis mailto:davis@arc.ab.ca (403) 210-5334 Alberta Research Council
