-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 Python 2.7 and 3.3+.  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://six.readthedocs.io/.
-
-Bugs can be reported to https://github.com/benjaminp/six.  The code can also
-be found there.
