 Hacky Python interface to Yamaha RX-V*73 receivers (mainly  RX-V473)
 
+Usage
+=====
+
+The easiest way to start using is to let SSDP find all available receivers. 
+In most cases **rxv** module will manage to obtain locations of local compatible devices::
+
+  >>> import rxv
+  >>> receivers = rxv.find()
+  >>> print(receivers)
+  [<RXV model_name="RX-V473" ctrl_url="http://192.168.1.116:80/YamahaRemoteControl/ctrl" at 0x2c1c1d0>]
+  >>> rx = receivers[0]
+  >>> rx.on = True
+  >>> rx.volume 
+  -51.0
+  >>> rx.inputs
+  {'AUDIO': None,
+  'HDMI1': None,
+  'HDMI2': None,
+  (...)
+  'iPod (USB)': 'iPod_USB'}
+  >>> rx.input 
+  "NET RADIO"
+  >>> rx.input = "HDMI1"
+  >>> rx.input 
+  "HDMI1"
+  
+
+If SSDP causes you some problems, `ctrl_url` can be provided by hand.::
+
+  >>> rx = rxv.RXV("http://192.168.1.116:80/YamahaRemoteControl/ctrl", "RX-V473")
