At a previous job we implemented a branch system that was external to
the core source control system.  One of the good things it did was to
"reroot" a branch - i.e. move the branch point.  The merge process
required the branch to be rerooted at the head of the trunk first,
then merged back to the trunk.

I wish CVS could do this.
