 <h2>DESCRIPTION</h2>
 
-The GRASS program <em>d.colortable</em> 
-is used to display the color table associated with a raster map layer in the 
-active frame on the graphics monitor. The <em>map</em> name should be 
-an available raster map layer in the user's current mapset search path 
-and location. 
-
-<p>If the <em>values</em> of both <em>lines</em> and <em>cols</em> are
-not specified by the user, <em>d.colortable</em> 
-divides the active frame equally among the number of categories 
-present in the named raster map layer. If one option is specified, 
-the other is automatically set to accommodate all categories. 
-If both are specified, as many categories as possible are displayed.

 <h2>EXAMPLE</h2>
 
 The user running the command: 
-<dl>
-<dd>
-<b>d.colortable map=</b><em>soils</em> 
-  <b>color=</b><em>red</em>
-  <b>lines=</b><em>1</em>
-  <b>columns =</b><em>3</em>
-</dl>
-would see the active graphics frame divided into three columns 
-extending the full frame height. The lines dividing the color table 
-associated with the <em>soils</em> map would be displayed in red. 
-The user would see, at most, only three of the colors from the <em>soils</em> 
-color table displayed in the active frame (because the user requested 
-that this frame be divided into three sections).
