Yes, that sounds reasonable. I definitly want to lower the extra work,
that's why we use CVS. ok: my proposal deleted :-)

The only question is: how to get instable code out of the stable release?
For example: The entire G3D section should not yet go into stable.
Then there are several modules to be commented. Probably we should
keep them in src-ball, but eleiminate them from the binary ball by
commenting in src/CMD/lists/GRASS. We should carefully revise this list

Ok, we have a sort of periodical stable branch then. This would even
simplify the 5.1 thing as we don't have three branches then.
However, this needs commit discipline: Only bugfixes are allowed
untilthe periodic stable branch is merged back after publishing the
stable release. Did I get it?

It' much more, Justin!
Thanks for the clarification.
