DBUS query question

[Brian Millett <bmillett gmail com>]

Hello,
  I'm looking at writing a script for the dispatcher to handle.  I need
to get from NetworkManager what the current active interface is.  How
can I query DBUS to get the active interface?  Is that the correct way
to do it?  I guess an other question is where can I find docs on the
api?

Thanks
