+    ``repoze.bfg.router.Router`` instance as the ``app`` argument.
+    The ``root`` returned is the application root object.  The
+    ``closer`` returned is a callable (accepting no arguments) that
+    should be called when your scripting application is finished using
+    the root.  If ``environ`` is not None, it is used as the
