Requirements
------------
This project requires Python 2.6 or later, PyPy 3-2.4, or PyPy-5.0.1.
Python versions 2.4-2.7 are supported in the python-2.4 branch.
The bytecode files it can read has been tested on Python bytecodes from
versions 1.5, 2.1-2.7, and 3.0-3.6 and the above-mentioned PyPy versions.
The code here can be run on Python versions 2.6 or later, PyPy 3-2.4,
