	      The <emphasis>evaluator</emphasis> is responsible for
	      peridically evaluating job sets, checking out their
	      dependencies off their version control systems (VCS),
	      and queueing new builds if the result of the evaluation
	      changed.  It is launched by the
	      <command>hydra_evaluator.pl</command> command.

	      The <emphasis>queue runner</emphasis> launches builds
	      (using Nix) as they are queued by the evaluator,
	      scheduling them onto the configured Nix hosts.  It is
	      launched using the
	      <command>hydra_queue_runner.pl</command> command.
