GPSBabel converts waypoints, tracks, and routes from one format to another,
whether that format is a common mapping format like Delorme, Streets and
Trips, or even a serial upload or download to a GPS unit such as those from
Garmin and Magellan. By flatting the Tower of Babel that the authors of
various programs for manipulating GPS data have imposed upon us, it returns
to us the ability to freely move our own waypoint data between the programs
and hardware we choose to use.
