Log::Dispatch is a collection of Perl modules useful for logging messages to
 multiple outputs, each of which can have a minimum and maximum log level. It
 is designed to be easily subclassed, both for creating a new dispatcher
 object and particularly for creating new outputs.
 .
 It also allows both global (dispatcher level) and local (logging object)
 message formatting callbacks which allows greater flexibility and reduces
 the need for subclassing.
