+#      A test that has a different result if the relay module is disabled
+#      (but the same result if just the dirauth module is disabled):

+#       - expected
+#       - error_no_dirauth
+#       - error_no_relay_dirauth
+#      (Disabling the relay module also disables dirauth module. But we don't
+#      want to encode that knowledge in this test script, so we supply a
+#      separate result file for every combination of disabled modules that
+#      has a different result.)
