 <h2>DESCRIPTION</h2>
 
-<b>r.surf.gauss</b> produces a raster map layer of Gaussian deviates whose
-mean and standard deviation can be expressed by the user. It uses a Gaussian
-random number generator. It is essentialy the same as <em>r.surf.random</em>,
-but uses a Gaussian random number generator instead.
