|GSAK (Geocaching Swiss Army Knife)||
This application is used to manage waypoint information downloaded from geocaching.com for the purposes of geocaching. The application is probably the "Best of breed" as there are some other applications out there to manage waypoints, but none as thorough or easy to use as GSAK. It is written by a guy named "Clyde" in all of his forums. It was written in Delphi 5.
