Listing 1: prq--A printer queue manager

##################################################
#
#   This is a simple script to check the printer
#   queue for each printer on the system and
#   give the user the option to remove any print
#   job that they may own. And provide the super-
#   user with quick interface to move print jobs
#   on the queue.
