A common lisp to c compiler by Heinz Knutzen <hk@informatik.uni-kiel.de>, Ulrich Hoffman <uho@informatik.uni-kiel.de> and Wolfgang Goerigk <wg@informatik.uni-kiel.de>. CLiCC is meant to be used as a supplement to existing clisp systems for generating portable applications. Target c code must be linked with CLiCC run-time library to produce an executable.

Version 0.6.2 conforms to a subset of common lisp and clos called CL_0 or CommonLisp_0 and based on cltl1. It runs with lucid lisp, akcl or clisp. Work on cltl2 and ansi-cl conformance is in progress.
