+    <p>GPSBabel converts waypoints, tracks, and routes from one common
+    mapping format to another or a serial upload or download to a GPS
+    unit such as those from Garmin.</p>
+
+    <p>GPSBabel supports several data formats and will be useful for
+    tasks such as geocaching, mapping, and converting from one GPS
+    unit to another.  Among the interesting formats it supports are
+    the GPS Exchange Format (GPX), Keyhole Markup Language (KML), several
+    GPS devices via a serial link, and various Geocaching data formats.
+    GPSBabel also supports various filters to manipulate the data.</p>
