+/*********************************************************************
+This is an Arduino library for our Monochrome SHARP Memory Displays
+
+ Pick one up today in the adafruit shop!
+ ------> http://www.adafruit.com/products/1393
+
+These displays use SPI to communicate, 3 pins are required to
+interface
+
+Adafruit invests time and resources providing this open source code,
+please support Adafruit and open-source hardware by purchasing
+products from Adafruit!
