+==============================
+
+The LiquidCrystal library comes bundled with the IDE.
+It controls the LCD using Arduino pins directly connected to the LCD.

+// This sketch is a wrapper sketch for the hd44780 library example.
+// Note:
+// This is not a normal sketch and should not be used as model or example
+// of hd44780 library sketches.
+// This sketch is simple wrapper that declares the needed lcd object for the
+// hd44780 library sketch.
+// It is provided as a convenient way to run a pre-configured sketch for
+// the i/o class.
+// The source code for this sketch lives in the hd44780 examples.
