MTLib is a library mod for use by Crafttweaker addons, it does not have to be used, but it does provide some helpful methods and classes to make Crafttweaker addons easier to create.
This includes all of Modtweaker util / helper classes, such as the IUndoable action classes and base command "dump" classes.
