 <h2>DESCRIPTION</h2>
 
-<em>d.path</em> enables shortest path vector networking - based on DGLib
-(Directed Graph Library) vector network library  
-(see <a href="http://grass.gdf-hannover.de/wiki/Vector_network_analysis">screenshot</a>).
+<em>d.path</em> enables shortest path vector networking.
 Costs may be either line lengths, or attributes saved in a database table.
 Supported are cost assignments for both arcs and nodes, and also different
 in both directions of a vector line. For areas cost will be calculated along

 <h2>EXAMPLE</h2>
 
+Interactive shortest path routing on road network (Spearfish region):

-# Spearfish
-
+g.region vector=roads
 d.vect roads
-d.path -b roads coor="601653.5,4922869.2","593330.8,4924096.6"
