CompeGPS™ data files are "character" separated text files like the pcx format. "Character" means special data lines can have their own separator.
Since release 6.1 of CompeGPS™, GPX is also a supported import/export format for waypoints, routes and tracks.
For more information please have a look at http://www.compegps.com
Index of route/track to write (if more the one in source).
Because this format supports only one route or track, this option may be used on output to select a single route or track from a collection of routes and tracks read from a more expressive format. If you have, say, a gpx file that contains two routes, you may use this option to write them one at a time to individual files.
gpsbabel -i gpx -f routes.gpx -o compegps,index=1 -F route1.txt -o compegps,index=2 -F route2.txt
Give points (waypoints/route points) a default radius (proximity).
This option specifies the default proximity for waypoints and route points.
