 	functions for the Raspberry Pi
 
+WiringPi2: WiringPi version 2 implements new functions for managing IO expanders.

 Prerequisites:
     You must have python-dev and python-setuptools installed
     If you manually rebuild the bindings with swig -python wiringpi.i
     then cat wiringpi_class.py >> wiringpi.py to get the class-based wrapper
 
 Get/setup repo:
-    git clone https://github.com/WiringPi/WiringPi-Python.git
+    git clone https://github.com/Gadgetoid/WiringPi2-Python.git
     cd WiringPi-Python
     git submodule update --init

-    import wiringpi
-    io = wiringpi.GPIO(wiringpi.GPIO.WPI_MODE_PINS)
-    io.pinMode(1,io.OUTPUT)
-    io.digitalWrite(1,io.HIGH)

-    GPIO with /sys/class/gpio (You must first export the interfaces):

-    serial.puts("hello")
-    serial.close()
