'''
This is the PythonTeX wrapper script.  It automatically detects the version
of Python, and then imports the correct code from pythontex2.py or 
pythontex3.py.  It is intended for use with the default Python installation 
on your system.  If you wish to use a different version of Python, you could 
launch pythontex2.py or pythontex3.py directly.  You should also consider the 
command-line option `--interpreter`.  This allows you to specify the command
that is actually used to execute the code from your LaTeX documents.  Except 
for Python console content, it doesn't matter which version of Python is used 
to launch pythontex.py; pythontex.py just manages the execution of code from
your LaTeX document.  The interpreter setting is what determines the version 
under which your code is actually executed.
