		Metronome is a scheduler and task runner.  It can be used locally as a

		via simple database rows, and optionally managed via AMQP events.
		Interval/time values are expressed with reasonably intuitive English
		phrases, ie.: 'at 2pm', or 'Starting in 20 minutes, run every 10 seconds
		and then finish in 2 days'.
