   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                                    #

1686 #  [5] an optional custom munge command
