+/* MOCK DEV
+ *
+ * This is a utility module.
+ * It initializes a minimalist browserifiable project
+ * that contains the Metamask UI, with a local background process.
+ *
+ * Includes a state reset button for restoring to initial state.
+ *
+ * This is a convenient way to develop and test the plugin
+ * without having to re-open the plugin or even re-build it.
+ *
+ * To use, run `npm run mock`.
