Common Lisp is a high-level, all-purpose, object-oriented, dynamic
programming language. GNU CLISP is a Common Lisp implementation by
Bruno Haible of Karlsruhe University and Michael Stoll of Munich
University, both in Germany. It mostly supports the Lisp described in
the ANSI Common Lisp standard. It runs on microcomputers (OS/2,
Windows NT/2000/XP, Windows 95/98/ME, Amiga 500-4000, Acorn RISC PC)
as well as on Unix workstations (Linux, SVR4, Sun4, DEC Alpha OSF,
HP-UX, BeOS, NeXTstep, SGI, AIX, Sun3 and others) and needs only 2 MB
of RAM.
It is Free Software and may be distributed under the terms of GNU GPL,
while it is possible to distribute commercial proprietary applications
compiled with GNU CLISP.
The user interface comes in English, German, French, Spanish, Dutch,
Russian and Danish, and can be changed at run time. GNU CLISP
includes an interpreter, a compiler, a debugger, CLOS, MOP, a foreign
language interface, sockets, i18n, fast bignums and more. An X11
interface is available through CLX, Garnet, CLUE/CLIO. GNU CLISP runs
Maxima, ACL2 and many other Common Lisp packages.
