From 1fbcd2ca178db28747046b5bd943c81176db9f65 Mon Sep 17 00:00:00 2001
From: Joshua Lock <josh@linux.intel.com>
Date: Tue, 3 Aug 2010 18:18:03 +0100
Subject: [PATCH] lib/oe: sync with OE.dev

Most notable change is the move to creating symlinks to patches in the metadata
tree rather than copying them.
