This is the Adafruit GPS library - the ultimate GPS library
for the ultimate GPS module!
Tested and works great with the Adafruit Ultimate GPS module
using MTK33x9 chipset
------> http://www.adafruit.com/products/746
Pick one up today at the Adafruit electronics shop
and help support open source hardware & software! -ada
Adafruit invests time and resources providing this open source code,
please support Adafruit and open-source hardware by purchasing
products from Adafruit!
