I was thinking about this with WRT to the meta-data systems.
e.g. say a raster map's units are °C or kg/m³ or µg/l.
Could "r.support units=" support that or would a user have to edit the
cell_misc/$MAP/units file themselves? And if they did edit it by hand,
would the (new) file be compatible with what GRASS expects? Would
d.legend, GUI profile tool, etc, transfer the degree symbol (or whatever)
unharmed? Could the map be transfered to another (foreign) system intact?
