From bea3d29ac007d6c8faca786538fafb0d7d789ffc Mon Sep 17 00:00:00 2001
From: Eric Greveson <eric@greveson.co.uk>
Date: Wed, 10 Jul 2013 11:50:45 +0100
Subject: Added "dbus-name" command line option to allow a D-Bus bus name other
 than "org.inkscape" to be specified. This allows multiple Inkscape instances
 to be controlled over D-Bus in a single user session.
