[GRASS-dev] moving r.cva into GRASS CVS

[Benjamin Ducke]

I am getting more and more requests about r.cva. Obviously, there
is a lot of people who know about and want to use it.
So far, none of them has been able to make any sense of the GEM
installation routine.

I suggest we include r.cva in the main GRASS CVS tree.
It is stable but with some poorly tested options. Together, we could
test and improve it in time for the GRASS 6.2.3 release.

With some recent fixes I made, r.cva (as opposed to r.los) runs fine
on Win32, as well.

Since r.cva can do all that r.los can do, I suggest replacing r.los
with a script that calls r.cva with the same parameters you would pass
to r.los. That way, we need to maintain only on code base.
It would probably be necessary to add an option to r.cva to specify
observer coordinates directly but that should not be hard to do.

If you all agree to that, I will just get in touch with Mark Lake
to make sure we have no licensing issues here and can put the code
under GPL.
