Racket is a full-spectrum programming language that inherits from Lisp
and Scheme but also provides dialects that support objects, types,
laziness, and many other paradigms. Racket's module system allows
programmers to write and link together components written in different
dialects.  Racket's libraries range from web servers to distributed
computing and from databases to charts.
