tuxtools : tuxtools is a collection of bash scripts and programs that make life easier when converting tuxracer tracks to extreme tux racer tracks. All code in this collections is licensed under the GPL version 3 You can find version-specific scripts in folders `0.61a` and `1.1`. `1.1` is for the commercial release of the game, and the conversion script has not been tested on all tracks. It is possible to use the 0.61 track conversion, but 3-D trees and herring will not translate correctly because of differing engine capabilities and definition files.
