issue2636-20090729.zip contains regex.py, _regex.h, _regex.c which will
work with Python 2.5 as well as Python 2.6, and also 2 builds of
_regex.pyd (for Python 2.5 and Python 2.6 on Windows).

This version supports accessing the capture groups by subscripting the
match object, for example:

>>> m = regex.match("(?<foo>.)(?<bar>.)", "abc")
>>> len(m)
3
>>> m[0]
'ab'
>>> m[1 : 3]
['a', 'b']
>>> m["foo"]
'a'
