29# Description:
30# ------------
31# PALM watchdog client for monitoring batch jobs on a variety of hosts specified
32# by the user. The watchdog server requires python 2.7 or higher installed on
33# host to be monitored.
34#
35# Instructions:
36# -------------
37# 1) Modify the header section of palm_wd
38# 2) Move .wd.olddata and .wd.newdata to your palm directory
39#    (e.g. /home/user/current_version/.wd.newdata etc.)
40# 3) Modify a copy of palm_wdd for each host to be monitored and move it to the
41#    respective hosts
42# 4) Start the client either from mrungui or from shell by "nohup palm_wd&"
43#
44# To do:
45# ------
46# 1) Add "Options", "Help" and "Manual"
47# 2) Move user settings to a configuration file
48#------------------------------------------------------------------------------!
