I was looking at making a skeleton file for ease of prototyping and while I have played with the json ones (they were pretty straight forward) the mhskel format looks like it probably comes out of a generator of some sort. How would one go about creating them? (specifically I would like to create one for standard unity 3d and unreal engine 4 humanoids for rapid prototyping without having to go through the modeling package).

But the docs are in a deplorable state
