+ * connector. In that case this transport will be used to communicate between
+ * the DevToolsServer living in the parent process and the DevToolsServer
+ * living in the process of the target frame.
+ *
+ * This is intended to be a replacement for child-transport.js which is a
+ * message-manager based transport.
