+ * This section describes the XBT synchronization tools. It defines types and
+ * functions very close to the pthread API, but widly usable. When used from
+ * the simulator, you will lock simulated processes as expected. When used
+ * from GRAS programs compiled for in-situ execution, you have synchronization
+ * mecanism portable to windows and UNIX. Nice, isn't it?
