# 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.)
