 ## How it works
 
 When the game is launched through steam, the tool creates a patched version of `eldenring.exe` in a temporary subdirectory while leaving the original intact. As long the flag `--with-eac` is not set, the tool modifies the steam launch command to launch the patched executable instead of `start_protected_game.exe`, thefore ensuring that the patched exe is never run with EAC enabled. After the game is closed, the patched executable is removed.
