53# Description:
54# ------------
55# PALM watchdog client for monitoring batch jobs on a variety of hosts specified
56# by the user. The watchdog server requires python 2.7 or higher installed on
57# host to be monitored.
58#
59# Instructions:
60# -------------
61# 1) Modify the header section of palm_wd
62# 2) Move .wd.olddata and .wd.newdata to your palm directory
63#    (e.g. /home/user/current_version/.wd.newdata etc.)
64# 3) Modify a copy of palm_wdd for each host to be monitored and move it to the
65#    respective hosts
66# 4) Start the client either from mrungui or from shell by "nohup palm_wd&"
67#
68# To do:
69# ------
70# 1) Add "Options", "Help" and "Manual"
71# 2) Move user settings to a configuration file
