# service: simple wrapper around start-stop-daemon
#
# Usage: service ACTION EXEC ARGS...
#
# Action:
# -S,--start start EXEC, passing it ARGS as its arguments
# -K,--stop stop EXEC (send it a $SERVICE_SIG_STOP signal)
# -R,--reload reload EXEC (send it a $SERVICE_SIG_RELOAD signal)
#
# Environment variables used:
# SERVICE_DAEMONIZE run EXEC in background
# SERVICE_WRITE_PID create a pid file and use it
# SERVICE_USE_PID assume EXEC creates its own pid file and use it
# SERVICE_PID_FILE pid file to use (default to /var/run/EXEC.pid)
# SERVICE_SIG_RELOAD signal used for reloading
# SERVICE_SIG_STOP signal used for stopping
# SERVICE_UID user EXEC should be run as
# SERVICE_GID group EXEC should be run as
#
# SERVICE_DEBUG don't do anything, but show what would be done
# SERVICE_QUIET don't print anything
#
