From 43bc7238761460dc068c671399cd5d2dbd0f3d91 Mon Sep 17 00:00:00 2001
From: Dan Stillman <dstillman@zotero.org>
Date: Mon, 23 Oct 2006 23:24:11 +0000
Subject: [PATCH] Addresses #161, interface with CSL repository

Client-side updates

(Note that translator updates were broken anyway, since the translator table was changed and the update mechanism wasn't, so that's fixed now too, and <=1.0.0b2.r1 won't be served updates via the repository.)
