Racket for Ubuntu

Racket for Ubuntu is a programming language. Racket allows you to script file systems and Web servers. With Racket for Ubuntu, you can easily prototype animations and complex GUIs. To organize things, you can mix and match classes, modules or components. Once your script turns into a large collection of modules, equip your Racket modules with explicit type declarations as needed. Racket comes in so many flavors because Racket is much more than a standard scripting language or a plain programming language. Racket supports language extensibility to an unequaled degree. In Racket, creating a new language is as easy as writing a new library.
