+; CONFIDENCE TEST FOR IMPLEMENTATION OF SRFI-26
+; =============================================
+;
+; Sebastian.Egner@philips.com, 3-Jun-2002.
+;
+; This file checks a few assertions about the implementation.
+; If you run it and no error message is issued, the implementation
+; is correct on the cases that have been tested.
+;
+; compliance:
+;   Scheme R5RS with
+;     SRFI-23: error
+;
+; loading this file into Scheme 48 0.57 after 'cut.scm' has been loaded:
+;   ,open srfi-23
+;   ,load check.scm
+
+; (check expr)
+;    evals expr and issues an error if it is not #t.
