+# 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
