DESCRIPTION
r.surf.random produces a raster map layer of uniform random deviates
whose range can be expressed by the user. It is essentialy the same as
r.surf.gauss, but uses a linear random number generator instead.
It uses the random number generator drand48() or rand(),
depending on the user's platform.
