+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)
+ >>> from decimal import Decimal
+ >>> json.loads('1.1', parse_float=Decimal) == Decimal('1.1')
+ True
+
+Specializing JSON object encoding::
+
+ >>> import simplejson as json
+ >>> def encode_complex(obj):
+ ... if isinstance(obj, complex):
+ ... return [obj.real, obj.imag]
+ ... raise TypeError(repr(o) + " is not JSON serializable")
+ ...
+ >>> json.dumps(2 + 1j, default=encode_complex)
+ '[2.0, 1.0]'
+ >>> json.JSONEncoder(default=encode_complex).encode(2 + 1j)
+ '[2.0, 1.0]'
+ >>> ''.join(json.JSONEncoder(default=encode_complex).iterencode(2 + 1j))
+ '[2.0, 1.0]'
+
+
+Using simplejson.tool from the shell to validate and pretty-print::
+
+ $ echo '{"json":"obj"}' | python -m simplejson.tool
+ {
+ "json": "obj"
+ }
+ $ echo '{ 1.2:3.4}' | python -m simplejson.tool

+ The _ssl module needs access to the type object defined in

+ C API of a module in a struct which then gets exported to

+
+ The code in socketmodule.c defines this struct (which currently

+ under the name "CAPI".
+
+ Other modules can now include the socketmodule.h file
+ which defines the needed C APIs to import and set up
+ a static copy of this struct in the importing module.
+
+ After initialization, the importing module can then
+ access the C APIs from the _socket module by simply
+ referring to the static struct, e.g.
+
+ Load _socket module and its C API; this sets up the global
+ PySocketModule:
+
+ if (PySocketModule_ImportModuleAndAPI())
+ return;
+
+
+ Now use the C API as if it were defined in the using

+ Support could easily be extended to export more C APIs/symbols

+
+Object types:
+
+ SSLSocket -- subtype of socket.socket which does SSL over the socket
+
+Exceptions:
+
+ SSLError -- exception raised for I/O errors
+
+Functions:
+
+ cert_time_to_seconds -- convert time string used for certificate
+ notBefore and notAfter functions to integer
+ seconds past the Epoch (the time values
+ returned from time.time())
+
+ fetch_server_certificate (HOST, PORT) -- fetch the certificate provided
+ by the server running on HOST at port PORT. No
+ validation of the certificate is performed.

+Integer constants:
+
+SSL_ERROR_ZERO_RETURN
+SSL_ERROR_WANT_READ
+SSL_ERROR_WANT_WRITE
+SSL_ERROR_WANT_X509_LOOKUP
+SSL_ERROR_SYSCALL
+SSL_ERROR_SSL
+SSL_ERROR_WANT_CONNECT
+
+SSL_ERROR_EOF
+SSL_ERROR_INVALID_ERROR_CODE
+
+The following group define certificate requirements that one side is
+allowing/requiring from the other side:
+
+CERT_NONE - no certificates from the other side are required (or will
+ be looked at if provided)
+CERT_OPTIONAL - certificates are not required, but if provided will be
+ validated, and if validation fails, the connection will
+ also fail
+CERT_REQUIRED - certificates are required, and will be validated, and
+ if validation fails, the connection will also fail
+
+The following constants identify various SSL protocol variants:
+
+PROTOCOL_SSLv2
+PROTOCOL_SSLv3
+PROTOCOL_SSLv23
+PROTOCOL_TLSv1
+PROTOCOL_NOSSLv2 -- anything except version 2
