executable hell a lot of applications these days are distributed in multiple executable files especially game mods launching these programs directly is fine and good but for things like mods for steam games that require a third party executable thats where the problems come in, especially on Linux. My local install of Modern Warfare 2 with IW4x installed has 3 executables iw4mp.exe iw4sp.exe iw4x.exe It gets away with this on steam by having 2 different titles for singleplayer and multiplayer...
