<h2>DESCRIPTION</h2>

<em>r.surf.gauss</em> produces a raster map 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><a href="r.surf.random.html">r.surf.random</a></em>, but uses a
Gaussian random number generator instead.
