  // The code supports the following hooks:
  // dartPrint(message):
  //    if this function is defined it is called instead of the Dart [print]
  //    method.
  //
  // dartMainRunner(main, args):
  //    if this function is defined, the Dart [main] method will not be invoked
  //    directly. Instead, a closure that will invoke [main], and its arguments
  //    [args] is passed to [dartMainRunner].
