From 8c077a4caa73c7e4a5e148195f1d6d3cdae572cf Mon Sep 17 00:00:00 2001
From: Dan McGee <dan@archlinux.org>
Date: Sun, 7 Feb 2010 09:57:26 -0600
Subject: Add OpenSearch support to the site

Implements FS#14185. It is a bit more complex than listed there as I wanted
to not hardcode the URLs in the descriptor file; to do this we need to make
it a template and fill some things in. We also need to serve the file using
the correct mime type.
