It's documented here:

http://docs.python.org/library/logging.config.html#dictionary-schema-details

(look for 'disable_existing_logger'), but having looked at it, it *is*
poorly documented and hard to find. I'll update the fileConfig section
to describe the behaviour more clearly.

Actually I wasn't clear enough in my earlier response. The behaviour
is that all loggers are disabled other than those explicitly named in
the configuration *and their descendants*.

I'm glad you brought these points up, they do highlight an area where
the documentation could be clearer. I'll get on it.
