# clisp 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. GNU CLISP includes an interpreter, a compiler, a debugger, a large subset of CLOS, a foreign language interface and a socket interface. An X11 interface is available through CLX, Garnet, CLUE/CLIO. GNU CLISP runs Maxima, ACL2 and many other Common Lisp packages.
