|  | Six is a Python 2 and 3 compatibility library.  It provides utility functions | 
|  | for smoothing over the differences between the Python versions with the goal of | 
|  | writing Python code that is compatible on both Python versions.  See the | 
|  | documentation for more information on what is provided. | 
|  |  | 
|  | Six supports every Python version since 2.6.  It is contained in only one Python | 
|  | file, so it can be easily copied into your project. (The copyright and license | 
|  | notice must be retained.) | 
|  |  | 
|  | Online documentation is at https://pythonhosted.org/six/. | 
|  |  | 
|  | Bugs can be reported to https://bitbucket.org/gutworth/six.  The code can also | 
|  | be found there. |
