   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                                    #

4058 various test commands. (default: off)
4059
4060 =item B<--diff>
4061
4062 Use C<diff -u> for comparing the expected output with the produced
4063 output. (default: use a built-in routine)
4064
4065 =item B<--flavor>|B<--flavour> I<flavour>
4066
4067 Override the expected results for results for a specific (OS) flavour.
4068 (default: unused)
