Shudder, indeed :).

Categories determine where a message came from within the system, not 
where it's going to, so I'd recommend leaving them untouched for what 
you're trying to accomplish.

If you want different kinds of messages to go to different output sinks, 
log levels are the recommended way.

In your case, you could log the debug messages like

     $logger->debug("a lowlevel message");

and important events, like when the program started, stopped, etc., via

     $logger->info("Program started");

Then, use

     http://log4perl.sourceforge.net/d/Log/Log4perl/FAQ.html#c7fa8

to channel messages of different priorities to different log files.
