	41	# Description:
	42	# ------------
	43	# PALM watchdog client for monitoring batch jobs on a variety of hosts specified
	44	# by the user
	45	#
	46	# Instructions:
	47	# -------------
	48	# 1) Modify the header section of palm_wd
	49	# 2) Move .wd.olddata and .wd.newdata to your palm directory
	50	# (e.g. /home/user/current_version/.wd.newdata etc.)
	51	# 3) Modify a copy of palm_wdd for each host to be monitored and move it to the
	52	# respective hosts
	53	# 4) Start the client either from mrungui or from shell by "nohup palm_wd&"
	54
	55	# To do:
	56	# ------
	57	# 1) Add "Options", "Help" and "Manual"
	58	# 2) Move user settings to a configuration file
