Package: starfighter Version: 1.1-3 Severity: wishlist Tags: patch All the game resources currently reside in the starfighter.pak file, but I didn't find any available tools for unpacking or repacking this file. I figured out the format by looking at the starfighter source, and created the attached python modules for packing and unpacking this .pak file format. Please consider including them in the package.
