  winreg.c

  Windows Registry access module for Python.

  * Simple registry access written by Mark Hammond in win32api
	module circa 1995.
  * Bill Tutt expanded the support significantly not long after.
  * Numerous other people have submitted patches since then.
  * Ripped from win32api module 03-Feb-2000 by Mark Hammond, and
    basic Unicode support added.
