Common Lisp is a high-level, general-purpose, object-oriented, dynamic, functional programming language.
CLISP is a Common Lisp implementation by Bruno Haible, then of Karlsruhe University, and Michael Stoll, then of Munich University, both in Germany. It implements the language described in the ANSI Common Lisp standard with many extensions.
CLISP includes an interpreter, a compiler, a debugger, CLOS, MOP, a foreign language interface, i18n, POSIX and Perl regular expressions, a socket interface, fast bignums, arbitrary precision floats, and more. An X11 interface is available through CLX, Garnet and CLUE/CLIO. Command line editing is provided by readline. CLISP runs Maxima, ACL2 and many other Common Lisp packages.
CLISP runs on most GNU and Unix systems (GNU/Linux, GNU/Hurd, FreeBSD, NetBSD, OpenBSD, Solaris, Tru64, HP-UX, BeOS, IRIX, AIX, Mac OS X and others) and on other systems (Windows NT/2000/XP/Vista, Windows 95/98/ME) and needs only 4 MB of RAM.
