DESCRIPTION="Steel Bank Common Lisp (SBCL) is a Open Source development system for ANSI Common Lisp. It provides an interactive environment including an integrated native compiler, interpreter, and debugger. (And it, and its generated code, can also play nicely with Unix when running noninteractively.)"
