Python version and libraries
============================
* Python 2.6+
  As RHEL 6 adopted python 2.6, features only for 2.7+ should be avoided.

* standard library + widely used library
  Basically widely used == OpenStack adopted
  As usual there are exceptions. gevents. Or python binding library for other
  component.

Coding style guide
==================
* pep8
  As python is used, PEP8 is would be hopefully mandatory for
  http://www.python.org/dev/peps/pep-0008/

* pylint
  Although pylint is useful for finding bugs, but pylint score not very
  important for now because we're still at early development stage.

* Google python style guide is very helpful
