Python extension computing string distances and similarities

The Levenshtein Python C extension module contains functions for fast
computation of

* Levenshtein (edit) distance, and edit operations
* string similarity
* approximate median strings, and generally string averaging
* string sequence and set similarity

It supports both normal and Unicode strings.

Python 2.2 or newer is required. is an example SequenceMatcher-like class built on the top of
Levenshtein. It misses some SequenceMatcher's functionality, and has some extra

Levenshtein.c can be used as a pure C library, too. You only have to define
NO_PYTHON preprocessor symbol (-DNO_PYTHON) when compiling it. The
functionality is similar to that of the Python extension. No separate docs are
provided yet, RTFS. But they are not interchangeable:

* C functions exported when compiling with -DNO_PYTHON (see Levenshtein.h) are
not exported when compiling as a Python extension (and vice versa)
* Unicode character type used with -DNO_PYTHON is wchar_t, Python
extension uses Py_UNICODE, they may be the same but don't count on it
