I'd argue for something between these positions.
I'd stick to just a GRASS installation to keep it simple and relatively
small. But, I'd really recommend that there is the option of a SINGLE
installation package for users. Most of the Windows users I deal with are
intimidated by a package that they download and then find out that they have
to go somewhere else and install something different just to use the first
So can we include TclTk and Mysys, if needed, in a single package that
allows all of GRASS to run?
