+This file is only loaded when the game is launched with the "--luadebug" launch option.
+This allows mods to have access to your computer's files, which is necessary to read glitched item info that's printed to the game's log file.
+
+Having --luadebug on would allow malicious mods to delete your files, execute command prompt commands, and probably much more.
+USE AT YOUR OWN RISK.
