This wrapper works with Gtk-Server, a really wonderful program that enables the access to the GTK widget set for another process using many communication protocols like stdin/stdout, tcp/udp port, named pipe, etc.
It works with many common lisp implementations (Clisp, Sbcl, Cmucl, Lispworks) and on many platforms (Linux, MacOS X, Windows).
