``version_info`` value may be used for a more human-friendly encoding of the
same information.
+ The ``hexversion`` is a 32-bit number with the following layout
+
+ +-------------------------+------------------------------------------------+
+ | bits (big endian order) | meaning |
+ +=========================+================================================+
+ | :const:`1-8` | ``PY_MAJOR_VERSION`` (the ``2`` in |
+ | | ``2.1.0a3``) |
+ +-------------------------+------------------------------------------------+
+ | :const:`9-16` | ``PY_MINOR_VERSION`` (the ``1`` in |
+ | | ``2.1.0a3``) |
+ +-------------------------+------------------------------------------------+
+ | :const:`17-24` | ``PY_MICRO_VERSION`` (the ``0`` in |
+ | | ``2.1.0a3``) |
+ +-------------------------+------------------------------------------------+
+ | :const:`25-28` | ``PY_RELEASE_LEVEL`` (``0xA`` for alpha, |
+ | | ``0xB`` for beta, ``0xC`` for gamma and |
+ | | ``0xF`` for final) |
+ +-------------------------+------------------------------------------------+
+ | :const:`29-32` | ``PY_RELEASE_SERIAL`` (the ``3`` in |
+ | | ``2.1.0a3``) |
+ +-------------------------+------------------------------------------------+
+
+ thus ``2.1.0a3`` is hexversion ``0x020100a3``
