From ae0b81d4fa35ead8d2f5d43e1df3b1e179fa8693 Mon Sep 17 00:00:00 2001
From: knarf <knarf@17b73243-c579-4c4c-a9d2-2d5706c11dac>
Date: Wed, 27 Feb 2013 18:18:57 +0000
Subject: Add configuration option XARGS (much like TAR) to define the location
 of the 'xargs' command. This shouldn't be necessary on almost all systems,
 but sadly is on a few.
