+ * configuration backend for those too. stroke_t uses an own
+ * thread to read from the socket.
+ * 
+ * @warning DO NOT cast stroke_t to any of the implemented interfaces!
+ * stroke_t implements multiple interfaces, so you must use
+ * stroke_t.interface_xy to access the specific interface! You have
+ * been warned...
