I keep losing this utility, used as part of other tools to auto-update the AUTHORS and CONTRIBUTORS files. Check it in to the repo so I don't lose it, and so others can use it as well. Updates #12042 Change-Id: Ib5886b85799087aaaddcec4c81169e2726322c05 Reviewed-on: https://go-review.googlesource.com/16824 Reviewed-by: Russ Cox <rsc@golang.org>
