[GRASS-dev] image processing modules for GRASS GIS

[Yann]

The modules and programs have all been renamed i.* and I submitted a temporary 
re-organization of the imagery menu while waiting for better.

I do not have cvs access, so anybody interested in moving the modules is 
welcome. I would suggest to start with i.atcorr, a long term missing to GRASS 
(since 5.x).
