Without it you would probably get segmentation fault. I created a ticket for this: http://trac.osgeo.org/grass/ticket/2157 Having a closer look at my PROJ_UNITS file, I noticed unit was set to > "metre" and units was set to "metres".

One thing is the GUI part which I would have to write again for grass 6 because although it looks the same, the code of wxGUI is quite different. And write it for grass 6 would be more difficult. The other thing is that m.measure is only a grass 7 module so I don't know which backend should be used for grass 6. Regards, Anna > Yours, > V. > > >
