This is an implementation of Common Lisp as described in the book "Common Lisp - The Language" by Guy Steele Jr., Digital Press, 1st edition 1984 (often referred to as "CLtL1" for short). N.B. Building this package requires that you also have the sources for Kyoto Common Lisp (kcl), available at this site, but before getting kcl, you must complete and mail a licence form (kcl_licence), also available at this site.
