[Tracker] Tracker API for music player

[Pavel Rojtberg <lists rojtberg net>]

Hi,

I am the author of the unknown music player "YouAmp" and I am evaluation 
whether it is possible to replace my self written indexer with tracker.

I already read that the best way to use tracker is calling it over D-bus 
- but is there at least some D-Bus API documentation somewhere?

Particularly I need methods for:
* getting all music files below a certain directory
* filtering by artist, album, title
* sorting by artist, album, title AND mtime
* storing playlists

I also read Tracker supports Cover albumart fetching - does it work 
already? If so is there some documentation how to get the albumart?

I am using Tracker in Ubuntu Jaunty (currently 0.6.93)

Regards

Pavel
