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