 workNow
 =======
-Force all dwarves to look for a job immediately, or as soon as the game is unpaused.
+Don't allow dwarves to idle if any jobs are available.
+
+When workNow is active, every time the game pauses, DF will make dwarves
+perform any appropriate available jobs.  This includes when you one step
+through the game using the pause menu.  Usage:
+
+:workNow:       print workNow status
+:workNow 0:     deactivate workNow
+:workNow 1:     activate workNow (look for jobs on pause, and only then)
+:workNow 2:     make dwarves look for jobs whenever a job completes
