description     The Clisp Common Lisp Implementation
long_description        \
                CLISP is a Common Lisp implementation by Bruno Haible, \
                formerly of Karlsruhe University, and Michael Stoll, \
                formerly of Munich University, both in Germany. \
                It mostly supports the Lisp described in the \
                ANSI Common Lisp standard. \
                CLISP includes an interpreter, a compiler, almost all \
                of CLOS, a foreign language interface and a socket interface. \
                An X11 interface is available through CLX and Garnet. \
                Command line editing is provided by readline.
