archive.mk revision 1.9

      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 is more complicated and detailed than
      8 # strictly necessary.
