Matt's script is implement the agps online protocol released by u-blox.
User need to send a mail to u-blox to get their account. Simplified
process like:

* User acquired by send a empty mail to agps-account at u-blox.com get
their account

* user using the script or other application send account/password,
estimated lat/longitude information to u-blox by IP based link.

* get u-blox packet with assistance data

* script reset the GPS and feed the data into module by some binary command

* GPS module get the data, and knows what satellite currently over the
sky, eliminate the search/matching time of gps signal, and get quicker
fix.
