+        Plugins may also respond to the `frontpage_extras` hook with other
+        interesting things to put on the front page.  There's no way to
+        customize the order of these extras or which appear and which don't, at
+        the moment.  Such hooks should return an object with at least a
+        `template` attribute; the template will be called with the object
+        passed in as its `obj` argument.
