sre.py 2.4c

a reimplementation of _sre in pure Python

_sre.py is a reimplementation of CPython’s core regular expression engine, the _sre extension module. It’s written in pure Python to allow for easier experimentation and to benefit alternative Python implementations that can’t use C modules like the standard _sre. This version is compatible with _sre from CPython 2.3 and 2.4.
