From 7131b7ac87b9793c06d7b7e59df103658dd76ec7 Mon Sep 17 00:00:00 2001
From: Aaron Griffin <aaron@archlinux.org>
Date: Fri, 20 Oct 2006 06:26:55 +0000
Subject: A handful of minor changes:     * Removed the PMList typedef, in
 favor of the same naming scheme other       structs use 'pmlist_t'     *
 Added a time stamp on debug output, to make it more informational     * Moved
 alpm_db_register to _alpm_db_register, making the public function       not
 take a callback parameter
