+// in the Arduino SDK.
+// 
+// @brief 
+// This is a basic implementation of the LiquidCrystal library of the
+// Arduino SDK. The original library has been reworked in such a way that 
+// this class implements the all methods to command an LCD based
+// on the Hitachi HD44780 and compatible chipsets using the parallel port of
+// the LCD (4 bit and 8 bit).
