From 1290fba0a8e5f9a050e8510010a849338aab9756 Mon Sep 17 00:00:00 2001
From: Michael Prokop <mika@grml.org>
Date: Thu, 3 Jul 2014 12:58:46 +0200
Subject: [PATCH] New cmdline option -S + env variable SCRIPTS_DIRECTORY to set
 script directory

This allows us to run grml-live from the Git repository without
having /usr/share/grml-live/scripts available.

Thanks: Krisztian VASAS <iron@ironiq.hu> for the initial patch
