Python 3 compatibility
**********************
Intelhex library supports Python 2 (2.4-2.7) and Python 3 (3.2-3.6) without
external libraries or 2to3 tool. Enjoy.

I've successfully run unit tests of IntelHex against following versions of
Python:

	2.4.4, 2.5.4, 2.6.6 (32/64 bits), 2.7.9 (32/64 bits), 
        3.2.5 (32/64 bits), 3.3.5 (32/64 bits), 3.4.3 (32/64 bits),
        3.5.0a3 (32/64 bits),
        and also PyPy 2.5.1 (which is Python 2.7.9)


Which Python version should you use?
------------------------------------
If you don't really know which version of Python (2 or 3) you should use with
IntelHex then please check following pre-requisites:

1) Are you already have some Python installed on your computer and that
   version is supported by IntelHex (see above)?
2) Should you use another third-party libraries? If so, check their
   requirements.
3) Python 2.7 is the safest choice so far, but if you have a chance
   then try latest stable Python 3 version.
4) Updated by January 2018 - Python 3 is highly recommended.
