Usage: $0 [-n] [-t] [-v] <command> [<service>]
 
  command options: start|stop|restart|status|check|pause|resume|kill

  service options: all|<a service id from the etc/service-configuration.xml>
                   defaults to all

  The following options are available:

    -n    "No execute" mode.  Don't call Java to do anything.
    -t    Test mode.  Enable JPDA on port 8001.
    -v    Verbose mode.  When used with the "status" command, gives the
          results for all OpenNMS services.  When used with "start", enables
          some verbose debugging, such as details on garbage collection.
