+This example demonstrates how to use the FreetronicsLCD library, which extends the
+standard LiquidCrystal library to provide support for the Freetronics back light
+and Up/Down/Left/Right/Select buttons.  More information on the shield here:

+// Note: if you are using the USBDroid and have reassigned pin D9 on the LCD shield to some
+// other pin (e.g. A1), then you will need to initialize the shield with something like:
+// FreetronicsLCD lcd(A1);
