########################################
# NOTE
# The version v0.4 has only been tested with Xymon (server and client) 4.2.x.
#
# The color status with respects to queue status is arbitrary and should be
# reviewed for your particular environment.
#
# Tested on :
#   Solaris & Linux
#   Linux only (for v0.4)

########################################
# INSTALLATION
#  step 1  - copy to Xymon client's ext dir
#  step 2  - New clientlaunch.d/sge.cfg file
#  step 3  - restart Xymon client
#
# NOTE - the TEST variable in the configuration section, this is the name used
#        as the column header.
