1. To install CEF Python 3 package type:
   
   sudo python setup.py install

   This will install the cefpython3 package to
   /usr/local/lib/python2.7/dist-packages/

2. In the same directory that setup.py resides there is 
   an examples/ directory. Run some examples from there:

   cd examples/
   python pygtk_.py
   python pyqt.py
   python wxpython.py
   python kivy_.py

   cd wx/
   python sample1.py
   python sample2.py
   python sample3.py
