39# Description:
40# ------------
41# The hlrn_watchdog works for jobs on HLRN in Hannover/Berlin and with KDE.
42# It can be used for monitoring currently submitted jobs and will display
43# Running, Idle and Blocked jobs in a separate window, which is updated every
44# 10 minutes.
45# Starting: "hlrn_watchdog start <your hlrn username>"
46# Stopping: "hlrn_watchdog stop"
