        !             2: Man pages are indeed the only electronically-distributable
        !             3: documentation about "map".  Here's a cut at a LONG_DESC; it could be
        !             4: shortened by dropping the third and/or fourth paragraphs.

        !             8: "Map" draws outline maps of the world or any part of it on more than
        !             9: 35 different projections.  It is capable of superimposing text (such as
        !            10: city names), lines (such as airline routes), or user-defined symbols
        !            11: at positions specified by latitude and longitude.  Its
        !            12: device-independent output adapts readily to most plotting media.
        !            13: 
        !            14: In the simplest usage you need only specify projection:

        !            16: generates an automatically scaled world map.  Using options for
        !            17: windowing, scaling, orientation, overlaying, grid spacing, resolution,
        !            18: additional inputs, etc., you may obtain maps centered on a favorite

        !            20: overlays of different regions, distributional maps, polyhedral globes,
        !            21: and so on.
        !            22: 
        !            23: Besides the usual families of azimuthal, conic, and cylindrical
        !            24: projections, there are projections popular in astronomy, one for X-ray
        !            25: crystallography, two retroazimuthal projections for showing
        !            26: great-circle directions to, rather than from, a given place, an

        !            28: periodic maps.
        !            29: 
        !            30: The projection subroutines constitute a library that can be used
        !            31: independently of "map".  An auxiliary route-finder program determines
        !            32: orientation parameters for strip maps and generates great-circle

        !            34: 
        !            35: Included with "map" are digital data files for world shorelines, US
        !            36: state boundaries, and US county boundaries, all derived from
