+;;;; This file is for testing bivalent stream functionality, using
+;;;; test machinery which might have side effects (e.g.  executing
+;;;; DEFUN, writing files).  Note that the tests here might reach into
+;;;; unexported functionality, and should not be used as a guide for
+;;;; users.
+
+;;;; This software is part of the SBCL system. See the README file for
+;;;; more information.
+;;;;
+;;;; While most of SBCL is derived from the CMU CL system, the test
+;;;; files (like this one) were written from scratch after the fork
+;;;; from CMU CL.
+;;;; 
+;;;; This software is in the public domain and is provided with
+;;;; absolutely no warranty. See the COPYING and CREDITS files for
+;;;; more information.
+
+;;; Test character decode restarts.
