   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                                    #

4423
4424 =over
4425

4428 Do not stop for user interaction or on errors. (default: off)
4429
4430 =item B<--debug>
4431
4432 This option enables the output of debug information when running the
4433 various test commands. (default: off)
4434
4435 =item B<--diff>
4436
4437 Use C<diff -u> for comparing the expected output with the produced
4438 output. (default: use a built-in routine)
4439
4440 =item B<--flavor>|B<--flavour> I<flavour>
4441
4442 Override the expected results for results for a specific (OS) flavour.
4443 (default: unused)
4444
4445 =item B<--[no]ipv4>
4446
4447 Skip IPv4 related setup and tests (default: use ipv4)

4456
4457 =item B<--range> I<n0> I<n1>
4458

4460 test available".
4461
4462 =item B<--slow>
4463
4464 Insert some delays to compensate for a slow host system. (default: off)
4465
4466 =item B<--test> I<n>
4467
4468 Run the specified test. This option may used multiple times.
4469
4470 =item B<--update>

4472 Automatically update the recorded (expected) data on mismatch. (default: off)
4473
4474 =item B<--valgrind>
