   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                                    #

4392
4393 =over
4394

4398
4399 =item B<--debug>
4400
4401 This option enables the output of debug information when running the
4402 various test commands. (default: off)
4403
4404 =item B<--diff>
4405
4406 Use C<diff -u> for comparing the expected output with the produced
4407 output. (default: use a built-in routine)
4408
4409 =item B<--flavor>|B<--flavour> I<flavour>
4410
4411 Override the expected results for results for a specific (OS) flavour.
4412 (default: unused)
4413
4414 =item B<--[no]ipv4>
4415
4416 Skip IPv4 related setup and tests (default: use ipv4)

4425
4426 =item B<--range> I<n0> I<n1>
4427

4429 test available".
4430
4431 =item B<--slow>
4432
4433 Insert some delays to compensate for a slow host system. (default: off)
4434
4435 =item B<--test> I<n>
4436
4437 Run the specified test. This option may used multiple times.
4438
4439 =item B<--update>

4441 Automatically update the recorded (expected) data on mismatch. (default: off)
4442
4443 =item B<--valgrind>
