                      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:
                     15:         map mercator | plotfilter
                     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
                     19: city, strip maps along air routes, simulated space images, comparative
                     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
                     27: egocentric "New Yorker" projection, and four fascinating doubly
                     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
                     33: paths.
                     34: 
                     35: Included with "map" are digital data files for world shorelines, US
                     36: state boundaries, and US county boundaries, all derived from
                     37: government sources.
