From 65a523302462e738bd3c813bdae4d0a8a62990ac Mon Sep 17 00:00:00 2001
From: Dan McGee <dan@archlinux.org>
Date: Sun, 30 Jan 2011 19:15:51 -0600
Subject: Add new helper functions

Replace common behavior we had in some other places with
get_module_name, and add some basename/dirname replacements done in bash
to avoid the forks for the number of times we call these functions.
