   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                                    #

4413
4414 =over
4415

4418 Do not stop for user interaction or on errors. (default: off)
4419
4420 =item B<--debug>
4421
4422 This option enables the output of debug information when running the
4423 various test commands. (default: off)
4424
4425 =item B<--diff>
4426
4427 Use C<diff -u> for comparing the expected output with the produced
4428 output. (default: use a built-in routine)
4429
4430 =item B<--flavor>|B<--flavour> I<flavour>
4431
4432 Override the expected results for results for a specific (OS) flavour.
4433 (default: unused)
4434
4435 =item B<--[no]ipv4>
4436
4437 Skip IPv4 related setup and tests (default: use ipv4)

4444
4445 Keep the various output files produced during a test run. (default: don't keep)
4446
4447 =item B<--range> I<n0> I<n1>
4448

4450 test available".
4451
4452 =item B<--slow>
4453
4454 Insert some delays to compensate for a slow host system. (default: off)
4455
4456 =item B<--test> I<n>
4457
4458 Run the specified test. This option may used multiple times.
4459
4460 =item B<--update>
4461
4462 Automatically update the recorded (expected) data on mismatch. (default: off)
4463
4464 =item B<--valgrind>
