+A command line python module does not need to have the ``.py`` file extension.
+
+Only specify ``python`` as the command to ``env``. A system that does not
+provide the ``python`` command can install a virtual python environment or the
+user can prepend the specific Python versioned command to the python script on
+the command line when invoking the command.
