From 6dc61e7d9e87ad6821869dab61e5f005af2e0252 Mon Sep 17 00:00:00 2001
From: Lukas Fleischer <archlinux@cryptocrack.de>

Subject: Remove aurblup configuration file parser

Drop the (very bad) PHP parser and allow for passing all necessary
configuration via command line parameters.

Also, add a convenience wrapper written in PHP that parses the
configuration file and subsequently calls aurblup with correct command
line options.
