description="
An ANSI Common Lisp Implementation.

In computing, CLISP is an implementation of the programming language
Common Lisp originally developed by Bruno Haible and Michael Stoll for
the Atari ST.

LISP includes an interpreter, a bytecode compiler, debugger, socket
interface, high-level foreign language interface, strong
internationalization support, and two object systems:
Common Lisp Object System (CLOS) and metaobject protocol (MOP).

It is written in C and Common Lisp. It is now part of the GNU Project
and is free software, available under the terms of the GNU General
Public License (GPL).
