I think I do too. It is mainly from a maintenance standpoint. On the
down side, it separates some code out that seems like it should live
together. But, it does remove some artificial constraints on function
If we decide to do it, we should move to svn before we try it though.
That kind of re-org in CVS makes me cringe...
