From 2b7aa883aff6419e934d79652b4801e6e77a8eeb Mon Sep 17 00:00:00 2001
From: gjb <gjb@FreeBSD.org>
Date: Mon, 5 May 2014 23:01:01 +0000
Subject: Add a helper script for parsing 'svn log' for the 'Relnotes:' tag in
 case 'yes' is not explicitly the first string value following the tab.

As it turns out, a number of commits have bypassed
my filters (both email and 'svn log --search'), and
this script returns the results I want when doing
these searches.
