python-simplejson

simplejson is a simple, fast, complete, correct and extensible JSON
<http://json.org> encoder and decoder for Python 2.5+. It is pure Python code
with no dependencies, but includes an optional C extension for a serious speed
boost.

The encoder may be subclassed to provide serialization in any kind of
situation, without any special support by the objects to be serialized
(somewhat like pickle).

The decoder can handle incoming JSON strings of any specified encoding (UTF-8
by default).

simplejson is the externally maintained development version of the json library
included with Python 2.6 and Python 3.0, but maintains backwards compatibility
with Python 2.5.  It gets updated more regularly than the json module in the
python stdlib.
