Is there a dedicated interface to control Rune programatically? I'd like to be able to issue commands like play, pause, stop, volume, next, prev, etc. but without having to go through the web interface. I saw that some projects were issuing commands straight to MPD but I'm hoping for something at a higher level within the system so that all of the supported music services (e.g. MPD, SPOP) can be handled using the same interface.
