    Hello heroseh, I noticed you did a thing a few minutes
    (30+) ago? I've done the same thing. I decided to look
    it up and see what I could find. CTRL+F on the spec
    didn't help, probably because I didn't know what I was
    looking for, but these stack overflow posts had
    information. Also did this example program for you.
