Nice, but "r.landscape.evol.py" works only with the GRASS 6.5 version
of r.watershed, otherwise
r.terraflow must be used. Contrary to the 6.5 version, the 6.4 version
of r.watershed only supports SFD (D8) and only integer DEMs, floating
point DEMs are truncated to integer(, and it's slower and uses more
memory).
