Author: imp Date: Tue Jun 19 00:27:30 2018 New Revision: 335350 URL: https://svnweb.freebsd.org/changeset/base/335350 Log: Add my script for coping with git-svn and the need to rebase changes for different branches. It's a bit rough right now, but should be good enough for most people to try to use. It's definitely 'tools' tree quality.
