MTKBabel is a Perl program to operate the i-Blue 747 GPS data logger.
It should work also with other GPS devices based on the MediaTek MTK
chipset.

The main capabilities are:

* Command line interface
* Save data log in GPX and raw binary format
* If required retrieve all the data, also the old one being overlapped
* Change logging criteria: time, distance, speed
* Change log format
* START/STOP logging
* Set OVERLAP or STOP method on memory full
* Erase the internal memory

The program is written in Perl, and it was tested on Linux via USB
connection. One goal is easy portability to C and small RAM footprint.
