+<em>d.barscale</em> displays a barscale on the graphics monitor at the
+given screen coordinates. If no coordinates are given it will draw the
+barscale in the bottom left of the display. It can draw the scale or
+north arrow in a number of styles (see
+the <a href="http://grasswiki.osgeo.org/wiki/Cartography#Display_monitors">wiki
+page</a> for details).
 
+<p>
+If <b>-n</b> flag is given, <em>d.barscale</em> draws north arrow
+instead of the barscale. Style of north arrow can be controlled
+by <b>north_arrow</b> paramater.
 
 <h2>NOTE</h2>
 
 <em>d.barscale</em> will not work in Lat/Lon locations as the horizontal
-scale distance changes with latitude. Try <em>d.grid</em> instead.
