   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                                    #

4371 various test commands. (default: off)
4372
4373 =item B<--diff>
4374
4375 Use C<diff -u> for comparing the expected output with the produced
4376 output. (default: use a built-in routine)
4377
4378 =item B<--flavor>|B<--flavour> I<flavour>
4379
4380 Override the expected results for results for a specific (OS) flavour.
4381 (default: unused)
4382
4383 =item B<--[no]ipv4>

4398 test available".
4399
4400 =item B<--slow>
4401
4402 Insert some delays to compensate for a slow host system. (default: off)
4403
4404 =item B<--test> I<n>
4405
4406 Run the specified test. This option may used multiple times.
4407
4408 =item B<--update>
