From 85ae2bcd44de36b282ebe216ed64127d243e72c5 Mon Sep 17 00:00:00 2001
From: Dave Reisner <dreisner@archlinux.org>
Date: Mon, 4 Feb 2013 14:21:42 -0500
Subject: Add -P, --allpresets option
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

As a logical extension, allow the -p option to be specified multiple
times in order to process several presets at once.
