Where to find information about Nautilus D-Bus interface

I am planning to develop a command line application that interac开发者_JS百科t with Nautilus, but I cannot find a reference for the D-Bus interface that Nautilus exposes.

For the time being, the only DBUS interface that nautilus implements is this:

Although I haven't found any doc on this either, at least you can use sth like d-feet to find out what interface/method/etc. nautilus has.

(and I don't think there are a lot of useful functions~~)
