[mod_python] outputting to apache log

I have some session data that I would like to write into the apache log, 
to be used with a stats tool. (Prefereably NOT the error log.)

PythonLogHandler looks like it should be related to this task, but I 
could find nothing about writing a custom one in the docs:

http://www.modpython.org/live/current/doc-html/dir-handlers-plh.html

What's the best way to put data into the log?
