[GRASSLIST:1076] r.in.tiff and r.composite

[Luis Goncalves Seco]

Hi again,

I whould like to understand the logic of have two commands 
for import a tiff image in a single GRASS file?

Because r.in.tiff generate 3 files (r,g,b), I whould like 
to know if the ideia of the programmer, was permit that 
 the user could adjust (1-256) each color with 
r.composite?
if not why? and why not 2 commands in one, if we have 
programs like Gimp to do this before importing?

Thanks
