I get it. It's a program that reads in an INI file (probably called Episode.ini) which tells it what files to use. There's no UI in it because whoever wrote it couldn't be bothered/didn't see a need. And it's called Episode.exe as that's the most logical name for it in the absence of something like "KeWl Jj2 EpIsOdE MaKeR v1.33.7.exe".
