Testsuite: munge for TLS1.3 under GnuTLS

6 # This is the controlling script for the "new" test suite for Exim. It should #
7 # be possible to export this suite for running on a wide variety of hosts, in #
8 # contrast to the old suite, which was very dependent on the environment of #
9 # Philip Hazel's desktop computer. This implementation inspects the version #
10 # of Exim that it finds, and tests only those features that are included. The #
11 # surrounding environment is also tested to discover what is available. See #
12 # the README file for details of how it all works. #
13 # #
14 # Implementation started: 03 August 2005 by Philip Hazel #
15 # Placed in the Exim CVS: 06 February 2006 #

4264 various test commands. (default: off)
4265
4266 =item B<--diff>
4267
4268 Use C<diff -u> for comparing the expected output with the produced
4269 output. (default: use a built-in routine)
4270
4271 =item B<--flavor>|B<--flavour> I<flavour>
4272
4273 Override the expected results for results for a specific (OS) flavour.
4274 (default: unused)
4275
4276 =item B<--[no]ipv4>

4291 test available".
4292
4293 =item B<--slow>
4294
4295 Insert some delays to compensate for a slow host system. (default: off)
4296
4297 =item B<--test> I<n>
