[Twisted-Python] Need for multiple loggers...

Thanks but I think that answers the wrong question. In my original
application I have three different named loggers (the original app
is written in Python). I have logOp, logTrace, logDebug each of which
goes somewhere different (for instance logOp messages go to the
operators system, logDebug is sent to a non-rotated file and logTrace
goes to a rotating log file). Through out my application I will log
message to the appropriate logger, for example messages that I want
written out to the debug file I write as logDebug.msg(...). Those that I
want to trace objects moving around I will do logDebug.info(...). etc.

In Twisted.python.log it looks like there is a single logger and I do:
log.startLogging(...). What I need to know is how can I create three
different loggers in my new application. Do I need to subclass some
twisted class?
