# Analytic Information System start/stop script.

# Usually this is put in /etc/init.d (at least on machines SYSV R4 based
# systems) and linked to /etc/rc3.d/S99aissvc and /etc/rc0.d/K01aissvc.
# When this is done the ais service will be started when the machine is
# started and shut down when the systems goes down.
