DESCRIPTION

28       r.surf.fractal creates a fractal surface of a given fractal  dimension.
29       Uses  spectral synthesis method. Can create intermediate layers showing
30       the build up of different spectral coefficients (see Saupe,  pp.106-107
31       for an example of this).
32
33       Use  this  module  to  generate naturally looking synthetical elevation
34       models (DEM).
