+r"""JSON (JavaScript Object Notation) <http://json.org> is a subset of
+JavaScript syntax (ECMA-262 3rd edition) used as a lightweight data
+interchange format.
+
+:mod:`simplejson` exposes an API familiar to users of the standard library
+:mod:`marshal` and :mod:`pickle` modules. It is the externally maintained
+version of the :mod:`json` library contained in Python 2.6, but maintains
+compatibility with Python 2.4 and Python 2.5 and (currently) has
+significant performance advantages, even without using the optional C
+extension for speedups.
+
+Encoding basic Python object hierarchies::
+
+    >>> import simplejson as json
+    >>> json.dumps(['foo', {'bar': ('baz', None, 1.0, 2)}])
+    '["foo", {"bar": ["baz", null, 1.0, 2]}]'
+    >>> print json.dumps("\"foo\bar")
+    "\"foo\bar"
+    >>> print json.dumps(u'\u1234')
+    "\u1234"
+    >>> print json.dumps('\\')
+    "\\"
+    >>> print json.dumps({"c": 0, "b": 0, "a": 0}, sort_keys=True)
+    {"a": 0, "b": 0, "c": 0}
+    >>> from StringIO import StringIO
+    >>> io = StringIO()
+    >>> json.dump(['streaming API'], io)
+    >>> io.getvalue()
+    '["streaming API"]'
+
+Compact encoding::
+
+    >>> import simplejson as json
+    >>> json.dumps([1,2,3,{'4': 5, '6': 7}], separators=(',',':'))
+    '[1,2,3,{"4":5,"6":7}]'
+
+Pretty printing::
+
+    >>> import simplejson as json
+    >>> s = json.dumps({'4': 5, '6': 7}, sort_keys=True, indent='    ')
+    >>> print '\n'.join([l.rstrip() for l in  s.splitlines()])
+    {
+        "4": 5,
+        "6": 7
+    }
+
+Decoding JSON::
+
+    >>> import simplejson as json
+    >>> obj = [u'foo', {u'bar': [u'baz', None, 1.0, 2]}]
+    >>> json.loads('["foo", {"bar":["baz", null, 1.0, 2]}]') == obj
+    True
+    >>> json.loads('"\\"foo\\bar"') == u'"foo\x08ar'
+    True
+    >>> from StringIO import StringIO
+    >>> io = StringIO('["streaming API"]')
+    >>> json.load(io)[0] == 'streaming API'
+    True
+
+Specializing JSON object decoding::
+
+    >>> import simplejson as json
+    >>> def as_complex(dct):
+    ...     if '__complex__' in dct:
+    ...         return complex(dct['real'], dct['imag'])
+    ...     return dct
+    ...
+    >>> json.loads('{"__complex__": true, "real": 1, "imag": 2}',
+    ...     object_hook=as_complex)
+    (1+2j)

+
+        Note that currently only encodings that are a superset of ASCII work,
+        strings of other encodings should be passed in as :class:`unicode`.
+
+        *object_hook*, if specified, will be called with the result of every
+        JSON object decoded and its return value will be used in place of the

+
+        *object_pairs_hook* is an optional function that will be called with
+        the result of any object literal decode with an ordered list of pairs.
+        The return value of *object_pairs_hook* will be used instead of the

+        insertion). If *object_hook* is also defined, the *object_pairs_hook*
+        takes priority.
+
+        *parse_float*, if specified, will be called with the string of every
+        JSON float to be decoded.  By default, this is equivalent to
+        ``float(num_str)``. This can be used to use another datatype or parser
+        for JSON floats (e.g. :class:`decimal.Decimal`).
+
+        *parse_int*, if specified, will be called with the string of every
+        JSON int to be decoded.  By default, this is equivalent to

+        following strings: ``'-Infinity'``, ``'Infinity'``, ``'NaN'``.  This
+        can be used to raise an exception if invalid JSON numbers are
+        encountered.
+
+        *strict* controls the parser's behavior when it encounters an
+        invalid control character in a string. The default setting of
+        ``True`` means that unescaped control characters are parse errors, if

+        encoding of keys that are not str, int, long, float or None.  If
+        skipkeys is True, such items are simply skipped.
+
+        If ensure_ascii is true, the output is guaranteed to be str
+        objects with all incoming unicode characters escaped.  If
+        ensure_ascii is false, the output will be unicode object.
+
+        If check_circular is true, then lists, dicts, and custom encoded
+        objects will be checked for circular references during encoding to
+        prevent an infinite recursion (which would cause an OverflowError).
+        Otherwise, no such check takes place.
+
+        If allow_nan is true, then NaN, Infinity, and -Infinity will be
+        encoded as such.  This behavior is not JSON specification compliant,
+        but is consistent with most JavaScript based encoders and decoders.
+        Otherwise, it will be a ValueError to encode such floats.
+
+        If sort_keys is true, then the output of dictionaries will be
+        sorted by key; this is useful for regression tests to ensure
+        that JSON serializations can be compared on a day-to-day basis.
+
+        If indent is a string, then JSON array elements and object members
+        will be pretty-printed with a newline followed by that string repeated

+        representation without any newlines. For backwards compatibility with
+        versions of simplejson earlier than 2.1.0, an integer is also accepted

+
+        If specified, separators should be a (item_separator, key_separator)
+        tuple.  The default is (', ', ': ').  To get the most compact JSON
+        representation you should specify (',', ':') to eliminate whitespace.
+

+        that can't otherwise be serialized.  It should return a JSON encodable
