[1751]	32	# Bugfixes: runs on multiple hosts caused crash of the watchdog. Progress bar
	33	# occasionally showed wrong progress.
	34	# New: Hosts can be switched on/off and update_frequency can be modified via

	50	# Description:
	51	# ------------
	52	# PALM watchdog client for monitoring batch jobs on a variety of hosts specified
	53	# by the user
	54	#
	55	# Instructions:
	56	# -------------
	57	# 1) Modify the header section of palm_wd
	58	# 2) Move .wd.olddata and .wd.newdata to your palm directory
	59	# (e.g. /home/user/current_version/.wd.newdata etc.)
	60	# 3) Modify a copy of palm_wdd for each host to be monitored and move it to the
	61	# respective hosts
	62	# 4) Start the client either from mrungui or from shell by "nohup palm_wd&"
	63
	64	# To do:
	65	# ------
	66	# 1) Add "Options", "Help" and "Manual"
	67	# 2) Move user settings to a configuration file
