Woa, I didn't know about this. It would certainly be better than my 
solution here which was to add another tag for the image. Juergbi, can 
we get this added (or Ivan)?

That's not strictly true :)

Carlos did add documentation for libtracker-miner which you should be 
able to see. Also you can man tracker-miner-fs and tracker-miner-fs.cfg.

There are also the design documents in docs/design/ if you want to see 
how the infrastructure works with miners.

Adrien's work with facebook, flickr, etc, adds to libtracker-miner too 
but we are still working on migrating that.

Yea I agree, this is superb.
