[GRASS5] replacing tcltkgrass in 5.3-cvs

[Scott Mitchell]

I'm trying to figure out the sensible way to add Michael Barton's new 
tcltkgrass scripts to the 5.3 source tree, and need input.

It could be done by (at least):
(1) add tcltkgrass4/ under src and change the compilation list to point 
to this one instead of tcltkgrass ("à la" r.mapcalc3) - backwards 
compatible but adds more redundant stuff to the source tree, or
(2) replace all the existing tcltkgrass

Out of those, option 2 seems more sensible, especially since we can 
just revert in CVS if anything went wrong, BUT now, since there are a 
lot of files that changed, do I just overwrite with Michael's files and 
commit, or remove the existing src/tcltkgrass/ altogether then add the 
new tcltkgrass4 and commit, or... some other combination?

Thanks - I volunteered to do this and then realized I wasn't sure what 
the best strategy is.  A good CVS learning experience...
