D-Bus introspection

Sure, there’s already d-feet and a similar Qt tool but for people who hate using the mouse or are allergic to X, I’ve put together this cute little hack that provides bash completion to dbus-send(1). Unfortunately it depends on the XML introspection parser from dbus-glib so it’s not straightforward to add to mainline D-Bus. Could easily go in dbus-glib though. Then again, it would be nice if libdbus included an XML introspection parser. Decisions, decisions.
