+// Test code for Adafruit Flora GPS modules
+//
+// This code shows how to listen to the GPS module in an interrupt
+// which allows the program to have more 'freedom' - just parse
+// when a new NMEA sentence is available! Then access data when
+// desired.
+//
+// Tested and works great with the Adafruit Flora GPS module
+// ------> http://adafruit.com/products/1059
+// Pick one up today at the Adafruit electronics shop
+// and help support open source hardware & software! -ada
