;;; DESCRIPTION:
;;;
;;; This file uses a "Hellow world!" string which is in an another C
;;; file called hello_aux.c. Both hello.lisp and hello_aux.c are
;;; compiled and linked into either
;;;
;;;	1) a FASL file (see build_fasl.lisp)
;;;	2) a shared library (see build_dll.lisp)
;;;	3) or a standalone executable file. (build_exe.lisp)
;;;
;;; USE:
;;;
;;; Launch a copy of ECL and load this file in it
;;;
;;;	(load "readme.lisp")
