+   The following example in the :program:`mongo` shell adds the
+   ``DBQuery.Option.tailable`` and ``DBQuery.Option.awaitData`` flags
+   to ensure the cursor returned from the query is a tailable cursor
+   that waits for a few seconds when the cursor reaches the end of the

+
+   .. code-block:: javascript
+
+      var cursor = db.myCappedCollection.find().addOption( DBQuery.Option.tailable ).addOption( DBQuery.Option.awaitData );
