### BEGIN INIT INFO
# Provides: rtapp-example
# Should-Start:
# Default-Start: 3 4 5
# Short-Description: launcher script for realtime application
# Description: This script performs all system manipulations required for
#              starting/stopping rtapp-example (i.e. isolating cpus, moving IRQ
#              affinities, etc). and then starts or stops the rt applications
#              using the tuna command line tool
