The GCL system contains C and Lisp source files to build a Common
Lisp sytem.  The original KCL system was written by Taiichi Yuasa
and Masami Hagiya in 1984.  The AKCL system work was begun in 1987
by William Schelter and continued through 1994.  In 1994 AKCL was
released as GCL (GNU Common Lisp) under the GNU public library
license.

NOTE: GCL 2.4.0 supports Tk bindings with Tcl 8.0 and Tk 8.0.  This
port of GCL does not insist on Tcl/Tk, but will attempt to build with
Tcl/Tk support if the libraries are found at build time.
