22     Introduction
23     ============
24     ZukeBox is an abstraction for a JukeBox.
25     How works?
26         In a JukeBox somebody pay and choose a song for play, this way the
27     JukeBox should have default set of songs. ZukeBox has the same idea,
28     except for payment ;) , you can choose a song availble in the server 
29     called ZukeBox Server or send a request for server to play your music, 
30     
31     Thus the clientes should be scan the network and get services availble 
32     in ZukeBox Server.
33     Services availble are:
34         1. Show the songs availble in the ZukeBox Server.
35         2. Play a song availble.
36         3. Play a song sent by a control point.
37     Some services will be availble too throught dbus.service a method for 
38     rescan the default paths and save in the database.
