Thanks for looking this over.

This is a good point. I'm working on getting things functional for now.
I was really disorganised when making this so these scripts may or may
not work despite what I said in this thread. I'll attach what I have
currently here in this mail. The wrapper scripts went through many
iterations some worked, some didn't, and as you see, lwjgl is still
throwing a fit:

See above.

This is a good idea, I do like this. But, for now, I'm trying to make
the scripts functional before I do any sort of complex mod to the
codebase. I don't know much about the Java ecosystem, so the debugging
process has been a bit annoying. Perhaps someone with more experience
here could help?


Thanks.!
