I need help installing the flash light

[Phoroneus]

On a similar note, how is the flashlight mod accomplished if we own the game on Steam? Steam forces it to be run from the launcher, which doesn't appear to have any means of calling the separate config file the way you've described. Anyone with Steam have this figured out, or do I have to buy a retail copy to pull it off? (Yet another thing completely stupid about Steam, I might add.)
