Hello I'm a programing retard, though I'm quite interested in what this program can do. Could somebody please help me out with some of the basics, like commands, command functions, and what the hell are those numbers in the curly brackets for?

I have hope that I won't turn out to be a lost cause, I just need some guidance.

Windows or Mac version: Choose "Lesson" from the Examples menu. Then read the text.

Unix/Posix version: Run the commands: Then look at the graphics result in lesson-output.png, and then open the file input/lesson.cfdg in your favorite text editor and read it.
