From 2079e6c4b340cea55d8b9254bca54cf3ce486d7c Mon Sep 17 00:00:00 2001
From: Tom Willemsen
Date: Sun, 20 Jan 2013 15:58:35 +0100
Subject: Add support for the -f switch

The option `dispass-labelfile' specifies the labelfile you would like
to use instead of the one provided by DisPass itself.

These changes should be cleaned up later, but for now it works.
