Software needs to be approved, for usage on various Online contest
systems. This makes sure, that end user software is compatible to Online Scoring
systems around the planet and makes sure that flight tracks cannot be
manipulated afterwards. The CIVL approval means here, an IGC file is within the
specification. There are no rights, to get approval for every software.

Any kind of listed software or hardware here is "Subject to the approval of the
National contest". Also, in terms of centralized Cat-1 or Cat-2 events, any kind
of listed software here is "subject to local event rules". There exist no rights
to complain against National Cross Country Contests or Local Event Rules, based
on this Software list. Further it is important to understand that software
G-record generation is not 100% secure. Practically, the software generated
G-records can dissuade casual tampering but cannot prevent a technically
competent attacker.

Below a list of approved Software, a quasi standard since the project started in
2003 with HG/PG onlinecontest.org. Hans Trautenberg, Andreas Rieck, John
