   4 # This is the controlling script for the "new" test suite for Exim. It should #
   5 # be possible to export this suite for running on a wide variety of hosts, in #
   6 # contrast to the old suite, which was very dependent on the environment of   #
   7 # Philip Hazel's desktop computer. This implementation inspects the version   #
   8 # of Exim that it finds, and tests only those features that are included. The #
   9 # surrounding environment is also tested to discover what is available. See   #
  10 # the README file for details of how it all works.                            #

  12 # Implementation started: 03 August 2005 by Philip Hazel                      #
  13 # Placed in the Exim CVS: 06 February 2006                                    #
