I wrote a program called "graft-ripple", that takes a commit, and rewrites the current branch's history to reflect as if it started at that commit.

It doesn't ever actually work with diffs or anything, it just reads commits and trees and recreates them.

It's in the list archives, but I appear to have deleted it when I was cleaning up my archives.
