  Windows service definition for Jenkins agent.
  This service is powered by the WinSW project: https://github.com/kohsuke/winsw/

  You can find more information about available options here: https://github.com/kohsuke/winsw/blob/master/doc/xmlConfigFile.md
  Configuration examples are available here: https://github.com/kohsuke/winsw/tree/master/examples

  To uninstall, run "jenkins-slave.exe stop" to stop the service, then "jenkins-slave.exe uninstall" to uninstall the service.
  Both commands don't produce any output if the execution is successful.

       Missing arguments triggers the service mode

Available commands:
  install     install the service to Windows Service Controller
  uninstall   uninstall the service
  start       start the service (must be installed before)
  stop        stop the service
  stopwait    stop the service and wait until it's actually stopped
  restart     restart the service
  restart!    self-restart (can be called from child processes)
  status      check the current status of the service
  test        check if the service can be started and then stopped
  testwait    starts the service and waits until a key is pressed then stops the service
  version     print the version info
  help        print the help info (aliases: -h,--help,-?,/?)
