   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                                    #

4473 Do not stop for user interaction or on errors. (default: off)
4474
4475 =item B<--debug>
4476
4477 This option enables the output of debug information when running the
4478 various test commands. (default: off)
4479
4480 =item B<--diff>
4481
4482 Use C<diff -u> for comparing the expected output with the produced
4483 output. (default: use a built-in routine)
4484
4485 =item B<--flavor>|B<--flavour> I<flavour>
4486
4487 Override the expected results for results for a specific (OS) flavour.
4488 (default: unused)
4489
4490 =item B<--[no]ipv4>
4491
4492 Skip IPv4 related setup and tests (default: use ipv4)

4501
4502 =item B<--range> I<n0> I<n1>
4503

4505 test available".
4506
4507 =item B<--slow>
4508
4509 Insert some delays to compensate for a slow host system. (default: off)
4510
4511 =item B<--test> I<n>
4512
4513 Run the specified test. This option may used multiple times.
4514
4515 =item B<--update>
