<h2>GRASS GIS ${grass_version} Reference Manual</h2>

<p><b>Geographic Resources Analysis Support System</b>, commonly
referred to as <a href="http://grass.osgeo.org">GRASS</a>, is a <a
href="http://en.wikipedia.org/wiki/Geographic_information_system">Geographic
Information System</a> (GIS) used for geospatial data management and
analysis, image processing, graphics/maps production, spatial
modeling, and visualization. GRASS is currently used in academic and
commercial settings around the world, as well as by many governmental
agencies and environmental consulting companies.</p>

<p>This reference manual details the use of modules distributed with
Geographic Resources Analysis Support System (GRASS), an open source (GNU
