 To export to an 1-D hydrodynamic model a cross section and 
 cross-displ maps from the output of <em>v.civil.road</em> is 
 required. And a raster DEM too.

 <p>
+The edge definition must have two displaced lines, the first
+for representing the main channel bank station and the second
+for representing the left and right overbanks.

+<p>
+The cross-displ map have the distance between the cutoffs of the 
+displaced lines above and the cross sections. 
+
+<p>
+The lines of cross section map are 2D, and the cutoffs above are 
+within those lines, so you can move the nodes to adjust the 
+lines to the water flow

 You must give a prefix name for output files.
