# This RA starts $binfile with $cmdline_options as $user in $workdir and writes a $pidfile from that.
# If you want it to, it logs:
# - stdout to $logfile, stderr to $errlogfile or
# - stdout and stderr to $logfile
# - or to will be captured by lrmd if these options are omitted.
# Monitoring is done through $pidfile or your custom $monitor_hook script.
# The RA expects the program to keep running "daemon-like" and
# not just quit and exit. So this is NOT (yet - feel free to
# enhance) a way to just run a single one-shot command which just
# does something and then exits.
