From 93b792c56e3b2709b0d9d95501908c41992d5c00 Mon Sep 17 00:00:00 2001
From: Marc Espie <espie@cvs.openbsd.org>
Date: Thu, 30 Nov 2006 13:18:23 +0000
Subject: apply some normalization to some properties while reading or writing,
 for instance, parse Requirements correctly, and simplify Libs before writing.
 We normalize Libs before writing because it's more efficient.
