(It also includes a faster linebreaking algorithm for when speed is more important than quality.) This tutorial provides a brief introduction to the Racket programming language by using one of its picture-drawing libraries. Even if you don’t intend to use Racket for your artistic endeavours, the picture library supports interesting and enlightening examples. After all, a picture is worth five hundred “hello world”s.")))))
