docs: def init_module(path):
  
      """Attempt to import a Python module located at path.  If
      successful, and if the newly imported module has an init()
      function, then set the global PATH in order to simplify the
      add_bundle() interface and call init() on the module, passing the
      current global namespace, conveniently converted into a DictObj so
      that it can be accessed with normal module style dot notation
      instead of as a dict.
