From 4e02dead1488930b3e5e7afffbd045f03b12c9ad Mon Sep 17 00:00:00 2001
From: Joey Hess <joey@kodama.kitenet.net>
Date: Wed, 9 Jul 2008 22:39:26 -0400
Subject: [PATCH] Make it possible to load setup files w/o running them. Code
 needing to do so can call IkiWiki::Setup::load, and the values will be loaded
 into %IkiWiki::Setup::setup.
