It's a fair point. The line was more blurred when the logging package
was newly released into the wild ;-) But "no configuration" could be
caused e.g. by an unreadable config file, which might also be
categorised as a "misconfiguration".

Compatibility with 1.5.2 precludes use of the warnings module. If using
raiseExceptions meets your requirement, I'll use that. I'm not sure
it's a good idea for the behaviour to change between running with and
without -O.

You can always get my attention via email :-) The graphical utility
( is available from the download at

AFAIK it should work OK with 2.3.5, though I haven't tested it recently
as there wasn't much interest in it. In fact you're the first person to
ask! It generates a few extra entries in the config file which are used
by the utility only, which are seemingly regarded as "cruft" by most
