[Zope] Site Error Messages

[Michael]

I am trying to disable the traceback which appears in site error messages 
under "view source".  I located Application.py under lib/python/OFS and also 
HTTPResponse.py under lib/python/ZPublisher, but am not sure where to go from 
here.

I was able to make "site maintainer" hot using mailto:, and got rid of the 
paragraph telling you to view source, but I cannot figure out how to 
eliminate the traceback.  Any suggestions?
