+API Notes for the OpenDirectory and CFOpenDirectory frameworks
+Both the OpenDirectory framework and the embedded CFOpenDirectory framework are fully wrapped
+and can be used as described in the generic PyObjC documentation.
+The callback function is stored by the framework, the callable can therefore not be
+a generic callable, but must be a callable that is annotated using the ``objc.callbackFor``
+ def query_callback(query, value, context, error, info):
+The ``userInfo`` argument needs to be an integer.
