Queue Support
=============

The queue support module makes it possible to add log records to a queue
system.  This is useful for distributed setups where you want multiple
processes to log to the same backend.  Currently supported are ZeroMQ as
well as the :mod:`multiprocessing` :class:`~multiprocessing.Queue` class.
