     CMUCL is a free, high performance implementation of the Common Lisp
    8 8 
     programming language which runs on most major Unix platforms. It
    9 9 
     mainly conforms to the ANSI Common Lisp standard. CMUCL provides a
    10 10 
     sophisticated native code compiler; a powerful foreign function
    11 11 
     interface; an implementation of CLOS, the Common Lisp Object System,
    12 
     which includes multi-methods and a meta-object protocol; a source-level
    13 
     debugger and code profiler; and an Emacs-like editor implemented in
    14 
     Common Lisp. CMUCL is maintained by a team of volunteers collaborating
    15 
     over the Internet, and is mostly in the public domain.
