# Script to wrap a non-windowing clean script to provide a prompt 
# before the dtterm window closes, and to catch abnormal terminations.

# For any abnormal termination of the clean script, kill our parent
# process so that our grandparent will know that the script did not
# terminate normally.  (We expect our parent to be dtterm, and our
# grandparent to be allocate.)

# Trap any signal that would cause abnormal termination of the script,
# This catches use of ^C, ^Z, etc., and it also catches the HUP signal
# when the dtterm window is closed before the script is finished.
