# description: manages the Tecplot license manager

# tecplotlm is distributed in the hope that it will be useful, but WITHOUT

#     ####################################################################
#     # This file is *NOT* part of the official Tecplot 360 distribution #
#     ####################################################################
#
# Description:  Makes sure that the Tecplot license manager is started at boot.
#               This is particularly useful for people running Tecplot on Linux
#               laptops which are rebooted very often.
#
#               This init script is written for Fedora Core 6 but should
#               work with minor modifications on most Linux flavours.
#
# Installation: After dropping this file in your /etc/rc.d/init.d/ directory, make it
#               executable and add it to the relevant runlevels. 
#               On Fedora, use, as root:
#                    chkconfig --add tecplotlm
#               And the tecplot license manager should be up after the next reboot.
#
# Note: the license manager is not stopped (by this script) when shutting down,
# it is just left to die. This is because killing the license manager is very
# time consuming and it is simplier to let sysinit kill the process with a killall.
