-Python 3.x Compatibility
-------------------------
-
-OpenStackClient strives to be Python 3.3 compatible.  Common guidelines:
-
-* Convert print statements to functions: print statements should be converted
-  to an appropriate log or other output mechanism.
-* Prefer to x.items() over six.iteritems(x).
