From d9f9b87d3ff6621577aa15bf3304f73219f6d5f1 Mon Sep 17 00:00:00 2001
From: Dan McGee <dan@archlinux.org>
Date: Mon, 8 Aug 2011 15:24:04 -0500
Subject: Add a test harness for new pacsort command

Note that this is meant to exercise pacsort more than the underlying
version comparsion; that is better left to the standalone vercmptest.sh
test script.
