+#!/bin/sh
+#
+# This script can be provided anywhere an executable or command name is
+# wanted.  It prints its arguments, and its stdin, to its stderr, and
+# then exits nonzero.
+#
+# When using this it may be useful to provide </dev/null as a
+# redirection for the whole program under test.  Otherwise things
+# can mysteriously hang.
