      3 # Very basic demonstration of handling archives, based on the description
      4 # in PSD.doc/tutorial.ms.
      5 #
      6 # This test aims at covering the code, not at being an introduction to
      7 # archive handling. That's why it deviates from the tutorial style of
      8 # several other tests.
