    SpaceChart 3D starmapping program
    ---------------------------------

    SpaceChart is a program for displaying maps of the stars in 3D and rotate them.
    It is capable of showing only a subset of the stars in a given data file, and
    only those within a given distance of the center of the display. Also, it
    shows lines between stars that are closer than a given distance.

    For installation see the INSTALL file.

    Included with the program is the file gliese.dat, which is based on the Gliese
    Catalogue of Nearby Stars, 3rd version, which includes all known stars within
    25 parsecs of the Sun.

    Use Instructions
    ----------------

    Open a data file with the 'File/Open' menu item of the 'Open' toolbar menu. A
    map of the stars in the data file should appear in the main window. You can
    rotate it by moving the mouse across it with the right button pressed.

    The 'View Radius' scrollbar allows you to select which is the maximum distance
    from the center star you want to see. The 'Zoom' scrollbar magnifies the center
    of the image.

    If you click on a star a dialog will pop up showing the info about that star
    system. This dialog allows you to center the display on that star.

    The 'Max Link Shown' field select the maximum size for which links between the
    stars will be shown. How these links are drawn can be selected in the 'Links'
    page of the settings.

    The star selection dialog allows you to select a subset of the stars to be
    shown according to their luminosity, spectral class and multiplicity.
