+dill: serialize all of python
+-----------------------------
+
+About Dill
+==========
+
+``dill`` extends python's ``pickle`` module for serializing and de-serializing
+python objects to the majority of the built-in python types. Serialization
+is the process of converting an object to a byte stream, and the inverse
+of which is converting a byte stream back to a python object hierarchy.
+
+``dill`` provides the user the same interface as the ``pickle`` module, and
+also includes some additional features. In addition to pickling python
+objects, ``dill`` provides the ability to save the state of an interpreter
+session in a single command.  Hence, it would be feasable to save an
+interpreter session, close the interpreter, ship the pickled file to
+another computer, open a new interpreter, unpickle the session and
+thus continue from the 'saved' state of the original interpreter
+session.
+
+``dill`` can be used to store python objects to a file, but the primary
+usage is to send python objects across the network as a byte stream.
+``dill`` is quite flexible, and allows arbitrary user defined classes
+and functions to be serialized.  Thus ``dill`` is not intended to be
+secure against erroneously or maliciously constructed data. It is
+left to the user to decide whether the data they unpickle is from
+a trustworthy source.
+
+``dill`` is part of ``pathos``, a python framework for heterogeneous computing.
+``dill`` is in active development, so any user feedback, bug reports, comments,
+or suggestions are highly appreciated.  A list of issues is located at https://github.com/uqfoundation/dill/issues, with a legacy list maintained at https://uqfoundation.github.io/project/pathos/query.
+
+
+Major Features
+==============
+
+``dill`` can pickle the following standard types:
+
+    - none, type, bool, int, long, float, complex, str, unicode,
+    - tuple, list, dict, file, buffer, builtin,
+    - both old and new style classes,
+    - instances of old and new style classes,
+    - set, frozenset, array, functions, exceptions
+
+``dill`` can also pickle more 'exotic' standard types:
+
+    - functions with yields, nested functions, lambdas,
+    - cell, method, unboundmethod, module, code, methodwrapper,
+    - dictproxy, methoddescriptor, getsetdescriptor, memberdescriptor,
+    - wrapperdescriptor, xrange, slice,
+    - notimplemented, ellipsis, quit
+
+``dill`` cannot yet pickle these standard types:
+
+    - frame, generator, traceback
+
+``dill`` also provides the capability to:
+
+    - save and load python interpreter sessions
+    - save and extract the source code from functions and classes
+    - interactively diagnose pickling errors
+
+
+Current Release
+===============
+
+This documentation is for version ``dill-0.3.4``.
+
+The latest released version of ``dill`` is available from:
+
+    https://pypi.org/project/dill
+
+``dill`` is distributed under a 3-clause BSD license.
+
+    >>> import dill
+    >>> dill.license()
+
+
+Development Version
+===================
+
+You can get the latest development version with all the shiny new features at:
+
+    https://github.com/uqfoundation
+
+If you have a new contribution, please submit a pull request.
+
+
+Installation
+============
+
+``dill`` is packaged to install from source, so you must
+download the tarball, unzip, and run the installer::
+
+    [download]
+    $ tar -xvzf dill-0.3.4.tar.gz
+    $ cd dill-0.3.4
+    $ python setup py build
+    $ python setup py install
+
+You will be warned of any missing dependencies and/or settings
+after you run the "build" step above.
+
+Alternately, ``dill`` can be installed with ``pip`` or ``easy_install``::
+
+    $ pip install dill
+
+
+Requirements
+============
+
+``dill`` requires:
+
+    - ``python``, **version == 2.7** or **version >= 3.6**, or ``pypy``
+
+Optional requirements:
+
+    - ``setuptools``, **version >= 0.6**
+    - ``pyreadline``, **version >= 1.7.1** (on windows)
+    - ``objgraph``, **version >= 1.7.2**
+
+
+Basic Usage
+===========
+
+``dill`` is a drop-in replacement for ``pickle``. Existing code can be
+updated to allow complete pickling using::
+
+    >>> import dill as pickle
+
+or::
+
+    >>> from dill import dumps, loads
+
+``dumps`` converts the object to a unique byte string, and ``loads`` performs
+the inverse operation::
+
+    >>> squared = lambda x: x**2
+    >>> loads(dumps(squared))(3)
+    9
+
+There are a number of options to control serialization which are provided
+as keyword arguments to several ``dill`` functions:
+
+* with *protocol*, the pickle protocol level can be set. This uses the
+  same value as the ``pickle`` module, *HIGHEST_PROTOCOL* or *DEFAULT_PROTOCOL*.
+* with *byref=True*, ``dill`` to behave a lot more like pickle with
+  certain objects (like modules) pickled by reference as opposed to
+  attempting to pickle the object itself.
+* with *recurse=True*, objects referred to in the global dictionary are
+  recursively traced and pickled, instead of the default behavior of
+  attempting to store the entire global dictionary.
+* with *fmode*, the contents of the file can be pickled along with the file
+  handle, which is useful if the object is being sent over the wire to a
+  remote system which does not have the original file on disk. Options are
+  *HANDLE_FMODE* for just the handle, *CONTENTS_FMODE* for the file content
+  and *FILE_FMODE* for content and handle.
+* with *ignore=False*, objects reconstructed with types defined in the
+  top-level script environment use the existing type in the environment
+  rather than a possibly different reconstructed type.
+
+The default serialization can also be set globally in *dill.settings*.
+Thus, we can modify how ``dill`` handles references to the global dictionary
+locally or globally::
+
+    >>> import dill.settings
+    >>> dumps(absolute) == dumps(absolute, recurse=True)
+    False
+    >>> dill.settings['recurse'] = True
+    >>> dumps(absolute) == dumps(absolute, recurse=True)
+    True
+
+``dill`` also includes source code inspection, as an alternate to pickling::
+
+    >>> import dill.source
+    >>> print(dill.source.getsource(squared))
+    squared = lambda x:x**2
+
+To aid in debugging pickling issues, use *dill.detect* which provides
+tools like pickle tracing::
+
+    >>> import dill.detect
+    >>> dill.detect.trace(True)
+    >>> f = dumps(squared)
+    F1: <function <lambda> at 0x108899e18>
+    F2: <function _create_function at 0x108db7488>
+    # F2
+    Co: <code object <lambda> at 0x10866a270, file "<stdin>", line 1>
+    F2: <function _create_code at 0x108db7510>
+    # F2
+    # Co
+    D1: <dict object at 0x10862b3f0>
+    # D1
+    D2: <dict object at 0x108e42ee8>
+    # D2
+    # F1
+    >>> dill.detect.trace(False)
+
+With trace, we see how ``dill`` stored the lambda (``F1``) by first storing
+``_create_function``, the underlying code object (``Co``) and ``_create_code``
+(which is used to handle code objects), then we handle the reference to
+the global dict (``D2``).  A ``#`` marks when the object is actually stored.
+
+
+More Information
+================
+
+Probably the best way to get started is to look at the documentation at
+http://dill.rtfd.io. Also see ``dill.tests`` for a set of scripts that
+demonstrate how ``dill`` can serialize different python objects. You can
+run the test suite with ``python -m dill.tests``. The contents of any
+pickle file can be examined with ``undill``.  As ``dill`` conforms to
+the ``pickle`` interface, the examples and documentation found at
+http://docs.python.org/library/pickle.html also apply to ``dill``
+if one will ``import dill as pickle``. The source code is also generally
+well documented, so further questions may be resolved by inspecting the
+code itself. Please feel free to submit a ticket on github, or ask a
+question on stackoverflow (**@Mike McKerns**).
+If you would like to share how you use ``dill`` in your work, please send
+an email (to **mmckerns at uqfoundation dot org**).

+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and

+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and

+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+

+
+`ml_dtypes` is a stand-alone implementation of several NumPy dtype extensions used in machine learning libraries, including:
+
+- [`bfloat16`](https://en.wikipedia.org/wiki/Bfloat16_floating-point_format):
+  an alternative to the standard [`float16`](https://en.wikipedia.org/wiki/Half-precision_floating-point_format) format
+- `float8_*`: several experimental 8-bit floating point representations
+  including:
+  * `float8_e4m3b11fnuz`
+  * `float8_e4m3fn`
+  * `float8_e4m3fnuz`
+  * `float8_e5m2`
+  * `float8_e5m2fnuz`
+- `int4` and `uint4`: low precision integer types.
+
+See below for specifications of these number formats.
+
+## Installation
+
+The `ml_dtypes` package is tested with Python versions 3.9-3.12, and can be installed
+with the following command:
+```
+pip install ml_dtypes
+```
+To test your installation, you can run the following:
+```
+pip install absl-py pytest
+pytest --pyargs ml_dtypes
+```
+To build from source, clone the repository and run:
+```
+git submodule init
+git submodule update
+pip install .
+```
+
+## Example Usage
+
+```python
+>>> from ml_dtypes import bfloat16
+>>> import numpy as np
+>>> np.zeros(4, dtype=bfloat16)
+array([0, 0, 0, 0], dtype=bfloat16)
+```
+Importing `ml_dtypes` also registers the data types with numpy, so that they may
+be referred to by their string name:
+
+```python
+>>> np.dtype('bfloat16')
+dtype(bfloat16)
+>>> np.dtype('float8_e5m2')
+dtype(float8_e5m2)
+```
+
+## Specifications of implemented floating point formats
+
+### `bfloat16`
+
+A `bfloat16` number is a single-precision float truncated at 16 bits.
+
+Exponent: 8, Mantissa: 7, exponent bias: 127. IEEE 754, with NaN and inf.
+
+### `float8_e4m3b11fnuz`
+
+Exponent: 4, Mantissa: 3, bias: 11.
+
+Extended range: no inf, NaN represented by 0b1000'0000.
+
+### `float8_e4m3fn`
+
+Exponent: 4, Mantissa: 3, bias: 7.
+
+Extended range: no inf, NaN represented by 0bS111'1111.
+
+The `fn` suffix is for consistency with the corresponding LLVM/MLIR type, signaling this type is not consistent with IEEE-754.  The `f` indicates it is finite values only. The `n` indicates it includes NaNs, but only at the outer range.
+
+### `float8_e4m3fnuz`
+
+8-bit floating point with 3 bit mantissa.
+
+An 8-bit floating point type with 1 sign bit, 4 bits exponent and 3 bits mantissa. The suffix `fnuz` is consistent with LLVM/MLIR naming and is derived from the differences to IEEE floating point conventions. `F` is for "finite" (no infinities), `N` for with special NaN encoding, `UZ` for unsigned zero.
+
+This type has the following characteristics:
+ * bit encoding: S1E4M3 - `0bSEEEEMMM`
+ * exponent bias: 8
+ * infinities: Not supported
+ * NaNs: Supported with sign bit set to 1, exponent bits and mantissa bits set to all 0s - `0b10000000`
+ * denormals when exponent is 0
+
+### `float8_e5m2`
+
+Exponent: 5, Mantissa: 2, bias: 15. IEEE 754, with NaN and inf.
+
+### `float8_e5m2fnuz`
+
+8-bit floating point with 2 bit mantissa.
+
+An 8-bit floating point type with 1 sign bit, 5 bits exponent and 2 bits mantissa. The suffix `fnuz` is consistent with LLVM/MLIR naming and is derived from the differences to IEEE floating point conventions. `F` is for "finite" (no infinities), `N` for with special NaN encoding, `UZ` for unsigned zero.
+
+This type has the following characteristics:
+ * bit encoding: S1E5M2 - `0bSEEEEEMM`
+ * exponent bias: 16
+ * infinities: Not supported
+ * NaNs: Supported with sign bit set to 1, exponent bits and mantissa bits set to all 0s - `0b10000000`
+ * denormals when exponent is 0
+
+## `int4` and `uint4`
+
+4-bit integer types, where each element is represented unpacked (i.e., padded up
+to a byte in memory).
+
+NumPy does not support types smaller than a single byte. For example, the
+distance between adjacent elements in an array (`.strides`) is expressed in
+bytes. Relaxing this restriction would be a considerable engineering project.
+The `int4` and `uint4` types therefore use an unpacked representation, where
+each element of the array is padded up to a byte in memory. The lower four bits
+of each byte contain the representation of the number, whereas the upper four
+bits are ignored.
+
+## Quirks of low-precision Arithmetic
+
+If you're exploring the use of low-precision dtypes in your code, you should be
+careful to anticipate when the precision loss might lead to surprising results.
+One example is the behavior of aggregations like `sum`; consider this `bfloat16`
+summation in NumPy (run with version 1.24.2):
+
+```python
+>>> from ml_dtypes import bfloat16
+>>> import numpy as np
+>>> rng = np.random.default_rng(seed=0)
+>>> vals = rng.uniform(size=10000).astype(bfloat16)
+>>> vals.sum()
+256
+```
+The true sum should be close to 5000, but numpy returns exactly 256: this is
+because `bfloat16` does not have the precision to increment `256` by values less than
+`1`:
+
+```python
+>>> bfloat16(256) + bfloat16(1)
+256
+```
+After 256, the next representable value in bfloat16 is 258:
+
+```python
+>>> np.nextafter(bfloat16(256), bfloat16(np.inf))
+258
+```
+For better results you can specify that the accumulation should happen in a
+higher-precision type like `float32`:
+
+```python
+>>> vals.sum(dtype='float32').astype(bfloat16)
+4992
+```
+In contrast to NumPy, projects like [JAX](http://jax.readthedocs.io/) which support
+low-precision arithmetic more natively will often do these kinds of higher-precision
+accumulations automatically:
+
+```python
+>>> import jax.numpy as jnp
+>>> jnp.array(vals).sum()
+Array(4992, dtype=bfloat16)
+```

+1. Download & installation
+--------------------------
+
+Mpmath requires Python 2.7 or 3.5 (or later versions). It has been tested
+with CPython 2.7, 3.5 through 3.7 and for PyPy.
+
+The latest release of mpmath can be downloaded from the mpmath
+website and from https://github.com/fredrik-johansson/mpmath/releases
+
+It should also be available in the Python Package Index at
+https://pypi.python.org/pypi/mpmath
+
+To install latest release of Mpmath with pip, simply run
+
+``pip install mpmath``
+
+Or unpack the mpmath archive and run
+
+``python setup.py install``
+
+Mpmath can also be installed using
+
+``python -m easy_install mpmath``
+
+The latest development code is available from
+https://github.com/fredrik-johansson/mpmath
+
+See the main documentation for more detailed instructions.
+
+2. Running tests
+----------------
+
+The unit tests in mpmath/tests/ can be run via the script
+runtests.py, but it is recommended to run them with py.test
+(https://pytest.org/), especially
+to generate more useful reports in case there are failures.
+
+You may also want to check out the demo scripts in the demo
+directory.
+
+The master branch is automatically tested by Travis CI.
+
+3. Documentation
+----------------
+
+Documentation in reStructuredText format is available in the
+doc directory included with the source package. These files
+are human-readable, but can be compiled to prettier HTML using
+the build.py script (requires Sphinx, http://sphinx.pocoo.org/).
+
+See setup.txt in the documentation for more information.
+
+The most recent documentation is also available in HTML format:
+
+http://mpmath.org/doc/current/
+
+4. Known problems
+-----------------
+
+Mpmath is a work in progress. Major issues include:
+
+* Some functions may return incorrect values when given extremely
+  large arguments or arguments very close to singularities.
+
+* Directed rounding works for arithmetic operations. It is implemented
+  heuristically for other operations, and their results may be off by one
+  or two units in the last place (even if otherwise accurate).
+
+* Some IEEE 754 features are not available. Inifinities and NaN are
+  partially supported; denormal rounding is currently not available
+  at all.
+
+* The interface for switching precision and rounding is not finalized.
+  The current method is not threadsafe.

+        :class:`http.client.HTTPConnection`.
+
+    :param port:
+        Port used for this HTTP Connection (None is equivalent to 80), passed
+        into :class:`http.client.HTTPConnection`.
+
+    :param strict:
+        Causes BadStatusLine to be raised if the status line can't be parsed

+        be a float or integer, which sets the timeout for the HTTP request,
+        or an instance of :class:`urllib3.util.Timeout` which gives you more
+        fine-grained control over request timeouts. After the constructor has
+        been parsed, this is always a `urllib3.util.Timeout` object.

+        in multithreaded situations. If ``block`` is set to False, more
+        connections will be created but they will not be saved once they've
+        been used.
+
+    :param block:
+        If set to True, no more than ``maxsize`` connections will be used at
+        a time. When no free connections are available, the call will block
+        until a connection has been released. This is a useful side effect for
+        particular multithreaded situations where one does not want to use more
+        than maxsize connections per host to prevent flooding.
+
+    :param headers:
+        Headers to include with all requests, unless other headers are given
+        explicitly.
+
+    :param retries:
+        Retry configuration to use by default with requests in this pool.
+
+    :param _proxy:
+        Parsed proxy URL, should not be used directly, instead, see
+        :class:`urllib3.ProxyManager`

+            these headers completely replace any pool-specific headers.
+
+        :param retries:
+            Configure the number of retries to allow before raising a
+            :class:`~urllib3.exceptions.MaxRetryError` exception.
+
+            Pass ``None`` to retry until you receive a response. Pass a
+            :class:`~urllib3.util.retry.Retry` object for fine-grained control
+            over different types of retries.
+            Pass an integer number to retry connection errors that many times,
+            but no other types of errors. Pass zero to never retry.
+
+            If ``False``, then retries are disabled and any exception is raised
+            immediately. Also, instead of raising a MaxRetryError on redirects,
+            the redirect response will be returned.
+
+        :type retries: :class:`~urllib3.util.retry.Retry`, False, or an int.
+
+        :param redirect:
+            If True, automatically handle redirects (status codes 301, 302,
+            303, 307, 308). Each redirect counts as a retry. Disabling retries
+            will disable redirect, too.
+
+        :param assert_same_host:
+            If ``True``, will make sure that the host of the pool requests is
+            consistent else will raise HostChangedError. When ``False``, you can
+            use the pool on an HTTP proxy and request foreign hosts.
+
+        :param timeout:
+            If specified, overrides the default timeout for this one
+            request. It may be a float (in seconds) or an instance of
+            :class:`urllib3.util.Timeout`.
+
+        :param pool_timeout:
+            If set and the pool is set to block=True, then this method will
+            block for ``pool_timeout`` seconds and raise EmptyPoolError if no
+            connection is available within the time period.
+
+        :param release_conn:
+            If False, then the urlopen call will not release the connection
+            back into the pool once a response is received (but will release if
+            you read the entire contents of the response such as when
+            `preload_content=True`). This is useful if you're not preloading
+            the response's content immediately. You will need to call
+            ``r.release_conn()`` on the response ``r`` to return the connection
+            back into the pool. If None, it takes the value of
+            ``response_kw.get('preload_content', True)``.
+
+        :param chunked:
+            If True, urllib3 will send the body using chunked transfer
+            encoding. Otherwise, urllib3 will send the body using the standard
+            content-length form. Defaults to False.
+
+        :param int body_pos:
+            Position to seek to in file-like body in the event of a retry or
+            redirect. Typically this won't need to be set because urllib3 will
+            auto-populate the value when needed.

+This module provides a pool manager that uses Google App Engine's
+`URLFetch Service <https://cloud.google.com/appengine/docs/python/urlfetch>`_.
+
+Example usage::
+
+    from urllib3 import PoolManager
+    from urllib3.contrib.appengine import AppEngineManager, is_appengine_sandbox
+
+    if is_appengine_sandbox():
+        # AppEngineManager uses AppEngine's URLFetch API behind the scenes
+        http = AppEngineManager()
+    else:
+        # PoolManager uses a socket-level API behind the scenes
+        http = PoolManager()
+
+    r = http.request('GET', 'https://google.com/')
+
+There are `limitations <https://cloud.google.com/appengine/docs/python/\
+urlfetch/#Python_Quotas_and_limits>`_ to the URLFetch service and it may not be
+the best choice for your application. There are three options for using
+urllib3 on Google App Engine:
+
+1. You can use :class:`AppEngineManager` with URLFetch. URLFetch is
+   cost-effective in many circumstances as long as your usage is within the
+   limitations.
+2. You can use a normal :class:`~urllib3.PoolManager` by enabling sockets.
+   Sockets also have `limitations and restrictions
+   <https://cloud.google.com/appengine/docs/python/sockets/\
+   #limitations-and-restrictions>`_ and have a lower free quota than URLFetch.
+   To use sockets, be sure to specify the following in your ``app.yaml``::
+
+        env_variables:
+            GAE_USE_SOCKETS_HTTPLIB : 'true'
+
+3. If you are using `App Engine Flexible
+<https://cloud.google.com/appengine/docs/flexible/>`_, you can use the standard
+:class:`PoolManager` without any configuration or special environment variables.
