1.  Introduction.
    -------------

    grib1profile works with GRIB edition 1 products in pure binary files
    with no blocking structure.

    Run the profiler:
      /home/ma/emos/bin/sgimips/grib1profile &    (SGI)
      /home/ma/emos/bin/linux/grib1profile &      (linux)
      /home/ma/emos/bin/rs6000/grib1profile &     (rs6000 and hpcx)
      /home/ma/emos/bin/grib1profile &            (VPP)


2.  Starting.
    ---------

    Use the 'File' option on the menu bar, select 'Open' and choose a file
    from the file selection box.

    Alternatively, start the viewer and give a file name on the command
    line:
      /home/ma/emos/bin/sgimips/grib1profile filename &    (SGI)
      /home/ma/emos/bin/linux/grib1profile filename &      (linux)
      /home/ma/emos/bin/rs6000/grib1profile filename &     (rs6000)
      /home/ma/emos/bin/grib1profile filename &                   (VPP)

    The viewer opens the selected file and reads through it, looking for
    GRIB products.  If none are found, the file is ignored.

    Information about products recognized in the current file is displayed
    as a list. The first product in the file is decoded and displayed in a
    popup window.  Examine other products in the file by selecting them from
    the list.

    Regular latitude/longitude grids and regular gaussian grids are displayed
    in an array layout as scrollable rows and columns numbered along the top
    and left sides.


3.  Stopping.
    ---------

    To quit the viewer, choose the 'File' option on the menu bar and select 
    'Quit'.
