+<h2>DESCRIPTION</h2>
+
+<em>v.to.lines</em> converts vector polygons (boundaries) to lines as well
+as vector points to lines via triangulations. This script is a wrapper
+script to <em>>v.category</em>, <em>v.delaunay</em>, and <em>v.edit</em>.
+
+<h2>NOTES</h2>
+
+<em>v.to.lines</em> is able to convert point data (via triangulation)
+and areas to lines (via boundary to line conversion).
+
+<h2>EXAMPLES</h2>
+
+The examples are for the North Carolina sample dataset location:
+
+<h3>Area to line conversion</h3>
+
+<div class="code"><pre>
+v.to.lines input=boundary_municp output=boundary_municp_lines
+</pre></div>
+
+<h3>Area to line conversion</h3>
+<div class="code"><pre>
+v.to.lines input=geodetic_pts output=geodetic_pts_lines
+</pre></div>
