I'm not going to stand in the way of those who really want to implement
this, but why is this necessary ?
eval(r.univar -g $map)
r.mapcalc new=old/$max
(and equivalent in other programming languages) works perfectly. Just
thinking that there are other priorities and that we are going further
from the KISS principle...
