This program generates, but does not display, image files containing raster
maps of the Earth.  It includes public-domain, vector data from which they
are drawn, describing the continents, bodies of water, boundaries of
countries and U.S. states, and a few cities.  Command-line options allow
centering the maps at a particular latitude and longitude and zooming in.
