"""
A test harness for the logging module. Tests thread safety.
To use as a server, run with no arguments in one process.
To use as a client, run with arguments "-client <filename>" where <filename>
is the name of a file containing a logging configuration.
The example files debug.ini, warn.ini, error.ini and critical.ini are
provided to use in the test. They each have a customized message format
(prefixed with their name) and the loggers have their levels set to the
value implied by their name.
