[Matthias Clasen <matthiasc src gnome org>]

commit 7bf2dc4c74613698fe1d7bb16e763b793e5590a4
Author: Matthias Clasen <mclasen redhat com>
Date:   Tue Apr 15 16:01:27 2014 -0700

    Convert to new-style commandline option handling
    
    This avoids manual parsing of options, and adds support
    for --gapplication-service.
