Ok, so I've been going back and adding tag stuff and whatnot because I hadn't been doing that earlier. Also continuing to update stuff, though at this point I'm starting to wonder if there's really anything more I should do. Maybe I could still do that shell script that retrieves the .jar file, but at the same time I wonder if there's a point to that anymore. It would be sort of convenient, but at the same time I'm not sure it's really necessary. It seems there wouldn't really be a problem with simply just getting core.jar from the Processing source code if there's no real problem with getting Processing. I might still develop that shell script if only for experimental purposes, but for right now I guess things are okay. Of course, if there's anything that's not okay, it would be good to tell me so I can work on fixing it. Feedback and stuff is appreciated for all the things I do, though it is not mandatory.
By the way, I apologize if the way I've handled this particular project wasn't the best. I'll admit that not everything was necessarily straightened out at the time. Some things were sort of rusty (admittedly I'm not necessarily much of a "pro 'grammer" to begin with), and I don't necessarily have the best development environment. Obviously, though, this work was definitely never meant to be a "magnum opus" of mine. It was just an old school project that I decided to build upon a bit. Hopefully, I can work to make things better on my end, and hopefully I'll be releasing something more sophisticated than squares moving around sometime soon.
