-# service: simple wrapper around start-stop-daemon
-#
-# 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 for matching
-#   SERVICE_MATCH_EXEC   use EXEC command-line for matching (default)
-#   SERVICE_MATCH_NAME   use EXEC process name for matching
-#   SERVICE_USE_PID      assume EXEC create its own pid-file and use it for matching
-#   SERVICE_NAME         process name to use (default to EXEC file part)
-#   SERVICE_PID_FILE     pid file to use (default to /var/run/$SERVICE_NAME.pid)
-#   SERVICE_SIG          signal to send when using -K
-#   SERVICE_SIG_RELOAD   default signal used when reloading
-#   SERVICE_SIG_STOP     default signal used when stopping
-#   SERVICE_STOP_TIME    time to wait for a process to stop gracefully before killing it
-#   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
-#
