dbus

In a background Python script I need to detect, when the system just woke up from suspend. What is a good way that does not rely on a root script but rather on python modules such as DBus?

I'm new to dbus so I could really use some example code. From what I read it's related to

org.freedesktop.UPower /org/freedesktop/UPower org.freedesktop.UPower.Resuming

Can anyone help me out with some code that connects the resuming signal to callback?
