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 |

thus ``2.1.0a3`` is hexversion ``0x020100a3``
