+jsonpickle
+==========
+jsonpickle is a library for the two-way conversion of complex Python objects
+and `JSON <http://json.org/>`_.  jsonpickle builds upon the existing JSON
+encoders, such as simplejson, json, and demjson.
+
+For complete documentation, please visit the
+`jsonpickle documentation <http://jsonpickle.readthedocs.io/>`_.
+
+Bug reports and merge requests are encouraged at the
+`jsonpickle repository on github <https://github.com/jsonpickle/jsonpickle>`_.
+
+jsonpickle supports Python 2.7 and Python 3.4 or greater.
+
+    **WARNING**:
+    jsonpickle can execute arbitrary Python code. Do not load jsonpickles from untrusted / unauthenticated sources.
+
+Why jsonpickle?
+===============
+Data serialized with python's pickle (or cPickle or dill) is not easily readable outside of python. Using the json format, jsonpickle allows simple data types to be stored in a human-readable format, and more complex data types such as numpy arrays and pandas dataframes, to be machine-readable on any platform that supports json. E.g., unlike pickled data, jsonpickled data stored in an Amazon S3 bucket is indexible by Amazon's Athena.
+
+Install
+=======
+
+Install from pip for the latest stable release:
+
+::
+
+    pip install jsonpickle
+
+Install from github for the latest changes:
+
+::
+
+    pip install git+https://github.com/jsonpickle/jsonpickle.git
+
+If you have the files checked out for development:
+
+::
+
+    git clone https://github.com/jsonpickle/jsonpickle.git
+    cd jsonpickle
+    python setup.py develop
+
+
+Numpy Support
+=============
+jsonpickle includes a built-in numpy extension.  If would like to encode
+sklearn models, numpy arrays, and other numpy-based data then you must
+enable the numpy extension by registering its handlers::
+
+    >>> import jsonpickle.ext.numpy as jsonpickle_numpy
+    >>> jsonpickle_numpy.register_handlers()
+
+Pandas Support
+==============
+jsonpickle includes a built-in pandas extension.  If would like to encode
+pandas DataFrame or Series objects then you must enable the pandas extension
+by registering its handlers::
+
+    >>> import jsonpickle.ext.pandas as jsonpickle_pandas
+    >>> jsonpickle_pandas.register_handlers()
+
+jsonpickleJS
+============
+`jsonpickleJS <https://github.com/cuthbertLab/jsonpickleJS>`_
+is a javascript implementation of jsonpickle by Michael Scott Cuthbert.
+jsonpickleJS can be extremely useful for projects that have parallel data
+structures between Python and Javascript.
+
+License
+=======
+Licensed under the BSD License. See COPYING for details.
+See jsonpickleJS/LICENSE for details about the jsonpickleJS license.
+
+Development
+===========
+
+Use `make` to run the unit tests::
+
+        make test
+
+`pytest` is used to run unit tests internally.
+
+A `tox` target is provided to run tests using tox.
+Setting ``multi=1`` tests using all installed and supported Python versions::
+
+        make tox
+        make tox multi=1
+
+`jsonpickle` itself has no dependencies beyond the Python stdlib.
+`tox` is required for testing when using the `tox` test runner only.
+
+The testing requirements are specified in `requirements-dev.txt`.
+It is recommended to create a virtualenv and run tests from within the
+virtualenv, or use a tool such as `vx <https://github.com/davvid/vx/>`_
+to activate the virtualenv without polluting the shell environment::
+
+        python3 -mvenv env3x
+        vx env3x pip install --requirement requirements-dev.txt
+        vx env3x make test
+
+`jsonpickle` supports multiple Python versions, so using a combination of
+multiple virtualenvs and `tox` is useful in order to catch compatibility
+issues when developing.

+"""Python library for serializing any arbitrary object graph into JSON.
+
+.. warning::
+
+    jsonpickle can execute arbitrary Python code. Do not load jsonpickles from
+    untrusted / unauthenticated sources.
+
+jsonpickle can take almost any Python object and turn the object into JSON.
+Additionally, it can reconstitute the object back into Python.
+
+The object must be accessible globally via a module and must
+inherit from object (AKA new-style classes).
+
+Create an object::
+
+    class Thing(object):
+        def __init__(self, name):
+            self.name = name
+
+    obj = Thing('Awesome')
+
+Use jsonpickle to transform the object into a JSON string::
+
+    import jsonpickle
+    frozen = jsonpickle.encode(obj)
+
+Use jsonpickle to recreate a Python object from a JSON string::
+
+    thawed = jsonpickle.decode(frozen)
+
+The new object has the same type and data, but essentially is now a copy of
+the original.
+
+.. code-block:: python
+
+    assert obj.name == thawed.name
+
+If you will never need to load (regenerate the Python class from JSON), you can
+pass in the keyword unpicklable=False to prevent extra information from being
+added to JSON::
+
+    oneway = jsonpickle.encode(obj, unpicklable=False)
+    result = jsonpickle.decode(oneway)
+    assert obj.name == result['name'] == 'Awesome'

+
+    :param unpicklable: If set to False then the output will not contain the
+        information necessary to turn the JSON data back into Python objects,
+        but a simpler JSON stream is produced.
+    :param max_depth: If set to a non-negative integer then jsonpickle will
+        not recurse deeper than 'max_depth' steps into the object.  Anything
+        deeper than 'max_depth' is represented using a Python repr() of the
+        object.
+    :param make_refs: If set to False jsonpickle's referencing support is
+        disabled.  Objects that are id()-identical won't be preserved across
+        encode()/decode(), but the resulting JSON stream will be conceptually
+        simpler.  jsonpickle detects cyclical objects and will break the cycle
+        by calling repr() instead of recursing when make_refs is set False.
+    :param keys: If set to True then jsonpickle will encode non-string
+        dictionary keys instead of coercing them into strings via `repr()`.
+        This is typically what you want if you need to support Integer or
+        objects as dictionary keys.
+    :param numeric_keys: Only use this option if the backend supports integer
+        dict keys natively.  This flag tells jsonpickle to leave numeric keys
+        as-is rather than conforming them to json-friendly strings.
+        Using ``keys=True`` is the typical solution for integer keys, so only
+        use this if you have a specific use case where you want to allow the
+        backend to handle serialization of numeric dict keys.
+    :param warn: If set to True then jsonpickle will warn when it
+        returns None for an object which it cannot pickle
+        (e.g. file descriptors).
+    :param max_iter: If set to a non-negative integer then jsonpickle will
+        consume at most `max_iter` items when pickling iterators.
+    :param use_decimal: If set to True jsonpickle will allow Decimal
+        instances to pass-through, with the assumption that the simplejson
+        backend will be used in `use_decimal` mode.  In order to use this mode
+        you will need to configure simplejson::
+
+            jsonpickle.set_encoder_options('simplejson',
+                                           use_decimal=True, sort_keys=True)
+            jsonpickle.set_decoder_options('simplejson',
+                                           use_decimal=True)
+            jsonpickle.set_preferred_backend('simplejson')
+
+        NOTE: A side-effect of the above settings is that float values will be
+        converted to Decimal when converting to json.
+    :param use_base85:
+        If possible, use base85 to encode binary data. Base85 bloats binary data
+        by 1/4 as opposed to base64, which expands it by 1/3. This argument is
+        ignored on Python 2 because it doesn't support it.
+    :param fail_safe: If set to a function exceptions are ignored when pickling
+        and if a exception happens the function is called and the return value
+        is used as the value for the object that caused the error
+    :param indent: When `indent` is a non-negative integer, then JSON array
+        elements and object members will be pretty-printed with that indent
+        level.  An indent level of 0 will only insert newlines. ``None`` is
+        the most compact representation.  Since the default item separator is
+        ``(', ', ': ')``,  the output might include trailing whitespace when
+        ``indent`` is specified.  You can use ``separators=(',', ': ')`` to
+        avoid this.  This value is passed directly to the active JSON backend
+        library and not used by jsonpickle directly.
+    :param separators:
+        If ``separators`` is an ``(item_separator, dict_separator)`` tuple
+        then it will be used instead of the default ``(', ', ': ')``
+        separators.  ``(',', ':')`` is the most compact JSON representation.
+        This value is passed directly to the active JSON backend library and
+        not used by jsonpickle directly.

+
+    The problem is that `__getnewargs__()`, `__getstate__()`, custom handlers,
