@Michael fine!
@Roger
this is pretty dirty "hack" I did not cross check if I got all
variables dealing with GRASS. I would like to do it more systematically.
Nevertheless as far as I understand the osgeo4w concept, we have only
two changing names. 1) the installation root directory 2) the GRASS
version name, that is used as a part of the internal path structure. I
would like to check this and if so it might be easy to integrate this in
initGRASS.
cheers Chris
