 <h2>DESCRIPTION</h2>
 
-<em>v.what</em>
-Outputs the category number value(s) associated with user-specified location(s) 
-in user-specified vector map layer(s).  This module was derived from the
-<em>d.what.vect</em> module by removing all interactive code and
-modification of the output for easy parsing. Using the <em>-g</em> flag
-generates script-style output which is easily parsable.
-<p>
