About this fork

Amecs-Reborn is a fork/merger of Amecs and Amecs-Api by Siphalor. Unfortunately, Siphalor stopped maintaining the Amecs projects,
and so I stepped in to port them to 1.21. Along the way, I took the time to make some improvements including merging the code bases, adding support for the Windows/Super/Command key, adding in platform specific translations for key names using a purpose built library, adding in toggles
for the mod's features, and adding full support for Controlling. I have even more stuff in the pipeline possibly including the potential for custom modifier keys.
