# prodllsubmit - Utility to release load leveler jobs into other 
#                user ids 
#
# History: 05/17/99 (Michaud) - Created for IBM SP 
# History: 04/14/00 (Gilbert) - Changed to pass Production 
#                               Environment variables to the
#                               subsequent loadleveler job.
# History: 09/01/01 (Gilbert) - Added timer to send a SIGUSR1 signal to
#                               this script after 90 seconds.
#                               If SIGUSR1 signal is received, the rsh
#                               command is probably hung and will be killed.
