   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                                    #

4073
4074 =item B<--debug>
4075
4076 This option enables the output of debug information when running the
4077 various test commands. (default: off)
4078
4079 =item B<--diff>
4080
4081 Use C<diff -u> for comparing the expected output with the produced
4082 output. (default: use a built-in routine)
4083
4084 =item B<--flavor>|B<--flavour> I<flavour>
4085
4086 Override the expected results for results for a specific (OS) flavour.
4087 (default: unused)
4088
4089 =item B<--[no]ipv4>

4104 test available".
4105
4106 =item B<--slow>
4107
4108 Insert some delays to compensate for a slow host system. (default: off)
4109
4110 =item B<--test> I<n>
4111
4112 Run the specified test. This option may used multiple times.
4113
4114 =item B<--update>
