using the script/command rlab

	******************************************************

	"rlab" lists the Sun workstations in the Newton Lab
	(ECCR 257) with information about their "up time"
	and current load average information.  This is similar
	to the information given by the command "w -u"; see
	the man page for "w".

	The three "load average" values are the number of jobs
	in the run queue over the last 1 minute, 5 minutes,
	and 15 minutes.   (run "man w")  Idle computers have a
	load average near 0.00.  Computers running multiple
	large jobs simultaneously will register a load average
	of near or over 1.00; don't start new large computations
	on such computers.
