-# 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
-#
