QuArKSAS v1.0 is now available for download! It's a free utility which can access files from games via Steam!
QuArKSAS stands for QuArK Steam Access System, since it was developed for QuArK to access Steam, but since it's a command-line driven program, anybody can use it. You don't need QuArK to run it. It's open-source and free, and a readme-file is included in the download.
