-# Usage: service ACTION EXEC ARGS...

-# Action:
-#   -C   check if EXEC is alive
-#   -S   start EXEC, passing it ARGS as its arguments
-#   -K   kill EXEC, sending it a TERM signal if not specified otherwise
-#
-# Environment variables exposed:
-#   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          signal to send when using -K
-#   SERVICE_SIG_RELOAD   default signal used for reloading
-#   SERVICE_SIG_STOP     default signal used for stopping
-#   SERVICE_STOP_TIME    time to wait for a process to stop gracefully before killing it
