Initially, my plan is to make available the main source files. None of this stuff is currently packaged or setup for installation, distribution, etc — but I will make more stuff available as time goes on.
If you don’t see something you need here, please contact 
and I’ll do my best.
This stuff is not even really alpha stage code, this is sort of raw, unfiltered, latest revisions of my project. There are likely some mistakes in comments because things have changed many many times. Obviously, the code should take precedence over the comments. I’m likely to not have updated an associated comment rather than get the code wrong. (I hope)
