  # This script shows the recommended style for scripts, with a
  # TestRunner class. The script is executed just once by each worker
  # process and defines the TestRunner class. The Grinder creates an
  # instance of TestRunner for each worker thread, and repeatedly calls
  # the instance for each run of that thread.

  # automatically registered with The Grinder console if you are using
  # it.

  # store thread-specific data.
