This example shows the typical output generated by
      TEST/REWRITE. Perhaps the single most important piece of
      information generated by TEST/REWRITE is the last few lines
      of the TEST/REWRITE output, 6, which give the channel to
      which TEST/REWRITE would submit a message with the specified
      test address and the form in which the test address would be
      rewritten for that channel. This output is invaluable when
      debugging configuration problems.
