Right now, those tools are mainly for command line users. Needless to say, this makes it very difficult to use for many people who just want to play a game, and who do not have a strong technical background.
During GSoC 2007, progress was made in unifying the internal code of these tools (mainly the compression tools). Also a basic GUI wrapper using wxWidget was added, as a first step towards making the tools usable for non-experts. However, this wrapper is right now a very
thing shell around the true complexity of the tools.
Your task would be to turn this GUI tool into a truly amazing and portable tool (usable on Linux, Windows and Mac OS X at least, ideally on more) which would be very easy to use for beginners, yet offers (optionally) the full power of the compression tools for experts.
