There can be up to 26 queues.  Each line of the queuedefs file must
have the following format:

q.NNjNNnNNw

where

q	is a letter a-z indicating the job queue

NNj	is the limit on jobs that can be running at one for the
	job queue (concurrency, NN is an integer defaulting to 100).

NNn	is the nice(1) value that is assigned each command executed for
	the job queue (default is 2)

NNw	is the time (in seconds) to wait before retrying to execute
	a command if all the criteria for running the command are not
	met (default 60).

Empty fields are initialized to default values.

Info gotten from UNIX System V System Release Description 2.0 #307-006

Hope this helps.
