MTLib is a Minecraft Java Edition mod that provides library files for Minetweaker Addons. It is designed for users who need to extend the functionality of their Minecraft server or client with custom scripts and tweaks. This mod is suitable for server administrators and players who want to customize their Minecraft experience.
MTLib is used by loading it on the server or client side, depending on the specific requirements of the Minetweaker Addons being used. It requires the presence of other mods, such as Minetweaker, to function properly. The mod is loaded using a compatible loader, and its functionality is accessed through the Minetweaker Addons that rely on it.
