Personally I don't see a reason to keep a ptools tree in lock step with
with a git tree. I all for not losing history (and I spent a bit of time
when
the tree was re-organized to keep the rcs history in tack).
At this point the git tree has full xfs history and I would think this would
be sufficient for what ever code archeology comes up.

Ya I'm still amazed those scripts are holding up given nobody is giving
them any TLC. :-(

The one thing about about SCM's that they are entirely a pain in the
ass, but one of the most important tools in software engineering.
So whatever happens it should be simple yet sufficient.
