 <h2>DESCRIPTION</h2>
 
 <em>v.centerline</em> creates a new map with a line representing an 
-approximation of the central tendency of a series of input lines. This 
-can for example, be the central line of a river represented by its two 
-sides, or a line representing the general direction of a series of 
-flight paths, etc.
+approximation of the central tendency of a series of input lines that
+all have similar trajectories. This can for example, be the central 
+line of a river represented by its two sides, or a line representing 
+the general direction of a series of flight paths, etc.

 Two algorithms are proposed in the module, both based on the idea of
