[Zope] Changing the name of the access log file

I have tried Googling for the answer to this but the words I have been trying seem to common - or return copies of how to turn on the rotating_file_logger. Did that, and it is swell. Now I would like my access log to be named something more descriptive than Z2.log. I am sure that someone has changed the logger - or the z2.py script - so that you can pass it a file name, not just the file path, for the access log. Can anyone point me to such a write up? Looking at the source, I have a couple of ideas what to chagne but would prefer to use a pre-tested hack to configure my first Zope server. -- cnk@caltech.edu
