+ * RegExpRoute makes it easy to create a regular expression based
+ * [Route]{@link workbox.routing.Route}.
+ *
+ * For same-origin requests the RegExp only needs to match part of the URL. For
+ * requests against third-party servers, you must define a RegExp that matches
+ * the start of the URL.
+ *
+ * [See the module docs for info.]{@link https://developers.google.com/web/tools/workbox/modules/workbox-routing}
