That's what I thought.  I'll post to the list and BCC you.

That solves both %c and 'category' -- thanks!  The 'category' filtering 
will be very useful.  :-)


I'm not certain if %T is doing the right thing (?).  You said there 
might be a bug.  Do you mean that the:

     ... Helper::help(...) called at ...

stances should be

     ... Log::Log4perl::__ANON__(...) called at ...

?  It's not a burning issue for me; I can use the output as is.
