/* Quick docs:
*
* "PyStr_*" works like PyUnicode_* on Python 3, but uses bytestrings (str)
* under Python 2.
*
* "PyBytes_*" work like in Python 3; on Python 2 they are aliased to their
* PyString_* names.
*
* "PyInt_*" works like PyLong_*
*
* Syntax for module initialization is as in Python 3, except the entrypoint
* function definition and declaration:
* PyMODINIT_FUNC PyInit_modulename(void);
* PyMODINIT_FUNC PyInit_modulename(void)
* {
* ...
* }
* is replaced by:
* MODULE_INIT_FUNC(modulename)
* {
* ...
* }
*
* In the entrypoint, create a module using PyModule_Create and PyModuleDef,
* and return it. See Python 3 documentation for details.
* For Python 2 compatibility, always set PyModuleDef.m_size to -1.
