This project is very unfinished, but I'd like to see what others can add to it, so I'm gonna share it, you can look at the notes and credits for a planned command list, or make your own commands Basic variable support is planned, insert variable names in place of numbers. It's handy to note that parameters are after the command name, and separated by spaces.
