From 643e98eeb42677a9ce8c32fa44d4ee61d02f7fcf Mon Sep 17 00:00:00 2001
From: Dan McGee <dan@archlinux.org>
Date: Sun, 30 Jan 2011 19:15:53 -0600
Subject: Use new helper functions instead of system commands

Replace all of the repeated calls to dirname and basename with our new
replacments. Also replace the 'grep ... /dev/null' idiom with calls to
'grep -q', which does exactly what we want.
