   * More specifically, this file is intended for vendors to implement
   * code needed to integrate testharness.js tests with their own test systems.
   *
   * Typically such integration will attach callbacks when each test is
   * has run, using add_result_callback(callback(test)), or when the whole test file has
   * completed, using add_completion_callback(callback(tests, harness_status)).
   *
   * For more documentation about the callback functions and the
   * parameters they are called with see testharness.js
