ANSI Common Lisp is a high-level, general-purpose 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 most Unix workstations (GNU/Linux, FreeBSD,
NetBSD, OpenBSD, Solaris, Tru64, HP-UX, BeOS, NeXTstep, IRIX, AIX and
others) and on other systems (Windows NT/2000/XP, Windows 95/98/ME)
and needs only 4 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.
