+ * \warning At least, I would like to present those sections in the right order, but doxygen prevents me

+ * - a) basic operations
+ * - b) Automatic parsing
+ * - c) Simple manual definitions
+ * - d) Callback Persistant State: Simple push/pop mecanism
+ * - e) Callback Persistant State: Full featured mecanism
