+.Synopsis
+Activate a Python virtual environment for the current PowerShell session.
+
+.Description
+Pushes the python executable for a virtual environment to the front of the
+$Env:PATH environment variable and sets the prompt to signify that you are
+in a Python virtual environment. Makes use of the command line switches as
+well as the `pyvenv.cfg` file values present in the virtual environment.
+
+.Parameter VenvDir
+Path to the directory that contains the virtual environment to activate. The
+default value for this is the parent of the directory that the Activate.ps1
+script is located within.
+
+.Parameter Prompt
+The prompt prefix to display when this virtual environment is activated. By
+default, this prompt is the name of the virtual environment folder (VenvDir)
+surrounded by parentheses and followed by a single space (ie. '(.venv) ').
+
+.Example
+Activate.ps1
+Activates the Python virtual environment that contains the Activate.ps1 script.
+
+.Example
+Activate.ps1 -Verbose
+Activates the Python virtual environment that contains the Activate.ps1 script,
+and shows extra information about the activation as it executes.
+
+.Example
+Activate.ps1 -VenvDir C:\Users\MyUser\Common\.venv
+Activates the Python virtual environment located in the specified location.
+
+.Example
+Activate.ps1 -Prompt "MyPython"
+Activates the Python virtual environment that contains the Activate.ps1 script,
+and prefixes the current prompt with the specified string (surrounded in
+parentheses) while the virtual environment is active.
+
+.Notes
+On Windows, it may be required to enable this Activate.ps1 script by setting the
+execution policy for the user. You can do this by issuing the following PowerShell
+command:
+
+PS C:\> Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
+
+For more information on Execution Policies:

+# MarkupSafe
+
+MarkupSafe implements a text object that escapes characters so it is
+safe to use in HTML and XML. Characters that have special meanings are
+replaced so that they display as the actual characters. This mitigates
+injection attacks, meaning untrusted user input can safely be displayed
+on a page.
+
+
+## Examples
+
+```pycon
+>>> from markupsafe import Markup, escape
+
+>>> # escape replaces special characters and wraps in Markup
+>>> escape("<script>alert(document.cookie);</script>")
+Markup('&lt;script&gt;alert(document.cookie);&lt;/script&gt;')
+
+>>> # wrap in Markup to mark text "safe" and prevent escaping
+>>> Markup("<strong>Hello</strong>")
+Markup('<strong>hello</strong>')
+
+>>> escape(Markup("<strong>Hello</strong>"))
+Markup('<strong>hello</strong>')
+
+>>> # Markup is a str subclass
+>>> # methods and operators escape their arguments
+>>> template = Markup("Hello <em>{name}</em>")
+>>> template.format(name='"World"')
+Markup('Hello <em>&#34;World&#34;</em>')
+```

+Installation
+============
+
+Binary wheel install
+--------------------
+
+PyNaCl ships as a binary wheel on macOS, Windows and Linux ``manylinux1`` [#many]_ ,
+so all dependencies are included. Make sure you have an up-to-date pip
+and run:
+
+.. code-block:: console
+
+    $ pip install pynacl
+
+Faster wheel build
+------------------
+
+You can define the environment variable ``LIBSODIUM_MAKE_ARGS`` to pass arguments to ``make``
+and enable `parallelization`_:
+
+.. code-block:: console
+
+    $ LIBSODIUM_MAKE_ARGS=-j4 pip install pynacl
+
+Linux source build
+------------------
+
+PyNaCl relies on `libsodium`_, a portable C library. A copy is bundled
+with PyNaCl so to install you can run:
+
+.. code-block:: console
+
+    $ pip install pynacl
+
+If you'd prefer to use the version of ``libsodium`` provided by your
+distribution, you can disable the bundled copy during install by running:
+
+.. code-block:: console
+
+    $ SODIUM_INSTALL=system pip install pynacl
+
+.. warning:: Usage of the legacy ``easy_install`` command provided by setuptools
+   is generally discouraged, and is completely unsupported in PyNaCl's case.
+
+.. _parallelization: https://www.gnu.org/software/make/manual/html_node/Parallel.html
+
+.. _libsodium: https://github.com/jedisct1/libsodium
+
+.. [#many] `manylinux1 wheels <https://www.python.org/dev/peps/pep-0513/>`_
+    are built on a baseline linux environment based on Centos 5.11
+    and should work on most x86 and x86_64 glibc based linux environments.
+
+Changelog
+=========
+
+1.5.0 (2022-01-07)
+------------------
+
+* **BACKWARDS INCOMPATIBLE:** Removed support for Python 2.7 and Python 3.5.
+* **BACKWARDS INCOMPATIBLE:** We no longer distribute ``manylinux1``
+  wheels.
+* Added ``manylinux2014``, ``manylinux_2_24``, ``musllinux``, and macOS
+  ``universal2`` wheels (the latter supports macOS ``arm64``).
+* Update ``libsodium`` to 1.0.18-stable (July 25, 2021 release).
+* Add inline type hints.
+
+1.4.0 (2020-05-25)
+------------------
+
+* Update ``libsodium`` to 1.0.18.
+* **BACKWARDS INCOMPATIBLE:** We no longer distribute 32-bit ``manylinux1``
+  wheels. Continuing to produce them was a maintenance burden.
+* Added support for Python 3.8, and removed support for Python 3.4.
+* Add low level bindings for extracting the seed and the public key
+  from crypto_sign_ed25519 secret key
+* Add low level bindings for deterministic random generation.
+* Add ``wheel`` and ``setuptools`` setup_requirements in ``setup.py`` (#485)
+* Fix checks on very slow builders (#481, #495)
+* Add low-level bindings to ed25519 arithmetic functions
+* Update low-level blake2b state implementation
+* Fix wrong short-input behavior of SealedBox.decrypt() (#517)
+* Raise CryptPrefixError exception instead of InvalidkeyError when trying
+  to check a password against a verifier stored in a unknown format (#519)
+* Add support for minimal builds of libsodium. Trying to call functions
+  not available in a minimal build will raise an UnavailableError
+  exception. To compile a minimal build of the bundled libsodium, set
+  the SODIUM_INSTALL_MINIMAL environment variable to any non-empty
+  string (e.g. ``SODIUM_INSTALL_MINIMAL=1``) for setup.
+
+1.3.0 2018-09-26
+----------------
+
+* Added support for Python 3.7.
+* Update ``libsodium`` to 1.0.16.
+* Run and test all code examples in PyNaCl docs through sphinx's
+  doctest builder.
+* Add low-level bindings for chacha20-poly1305 AEAD constructions.
+* Add low-level bindings for the chacha20-poly1305 secretstream constructions.
+* Add low-level bindings for ed25519ph pre-hashed signing construction.
+* Add low-level bindings for constant-time increment and addition
+  on fixed-precision big integers represented as little-endian
+  byte sequences.
+* Add low-level bindings for the ISO/IEC 7816-4 compatible padding API.
+* Add low-level bindings for libsodium's crypto_kx... key exchange
+  construction.
+* Set hypothesis deadline to None in tests/test_pwhash.py to avoid
+  incorrect test failures on slower processor architectures.  GitHub
+  issue #370
+
+1.2.1 - 2017-12-04
+------------------
+
+* Update hypothesis minimum allowed version.
+* Infrastructure: add proper configuration for readthedocs builder
+  runtime environment.
+
+1.2.0 - 2017-11-01
+------------------
+
+* Update ``libsodium`` to 1.0.15.
+* Infrastructure: add jenkins support for automatic build of
+  ``manylinux1`` binary wheels
+* Added support for ``SealedBox`` construction.
+* Added support for ``argon2i`` and ``argon2id`` password hashing constructs
+  and restructured high-level password hashing implementation to expose
+  the same interface for all hashers.
+* Added support for 128 bit ``siphashx24`` variant of ``siphash24``.
+* Added support for ``from_seed`` APIs for X25519 keypair generation.
+* Dropped support for Python 3.3.
+
+1.1.2 - 2017-03-31
+------------------
+
+* reorder link time library search path when using bundled
+  libsodium
+
+1.1.1 - 2017-03-15
+------------------
+
+* Fixed a circular import bug in ``nacl.utils``.
+
+1.1.0 - 2017-03-14
+------------------
+
+* Dropped support for Python 2.6.
+* Added ``shared_key()`` method on ``Box``.
+* You can now pass ``None`` to ``nonce`` when encrypting with ``Box`` or
+  ``SecretBox`` and it will automatically generate a random nonce.
+* Added support for ``siphash24``.
+* Added support for ``blake2b``.
+* Added support for ``scrypt``.
+* Update ``libsodium`` to 1.0.11.
+* Default to the bundled ``libsodium`` when compiling.
+* All raised exceptions are defined mixing-in
+  ``nacl.exceptions.CryptoError``
+
+1.0.1 - 2016-01-24
+------------------
+
+* Fix an issue with absolute paths that prevented the creation of wheels.
+
+1.0 - 2016-01-23
+----------------
+
+* PyNaCl has been ported to use the new APIs available in cffi 1.0+.
+  Due to this change we no longer support PyPy releases older than 2.6.
+* Python 3.2 support has been dropped.
+* Functions to convert between Ed25519 and Curve25519 keys have been added.
+
+0.3.0 - 2015-03-04
+------------------
+
+* The low-level API (`nacl.c.*`) has been changed to match the
+  upstream NaCl C/C++ conventions (as well as those of other NaCl bindings).
+  The order of arguments and return values has changed significantly. To
+  avoid silent failures, `nacl.c` has been removed, and replaced with
+  `nacl.bindings` (with the new argument ordering). If you have code which
+  calls these functions (e.g. `nacl.c.crypto_box_keypair()`), you must review
+  the new docstrings and update your code/imports to match the new
+  conventions.

+
+Acceptable password hashing for your software and your servers (but you should
+really use argon2id or scrypt)
+
+
+Installation
+============
+
+To install bcrypt, simply:
+
+.. code:: console
+
+    $ pip install bcrypt
+
+Note that bcrypt should build very easily on Linux provided you have a C
+compiler and a Rust compiler (the minimum supported Rust version is 1.56.0).
+
+For Debian and Ubuntu, the following command will ensure that the required dependencies are installed:
+
+.. code:: console
+
+    $ sudo apt-get install build-essential cargo
+
+For Fedora and RHEL-derivatives, the following command will ensure that the required dependencies are installed:
+
+.. code:: console
+
+    $ sudo yum install gcc cargo
+
+For Alpine, the following command will ensure that the required dependencies are installed:
+
+.. code:: console
+
+    $ apk add --update musl-dev gcc cargo
+
+
+Alternatives
+============
+
+While bcrypt remains an acceptable choice for password storage, depending on your specific use case you may also want to consider using scrypt (either via `standard library`_ or `cryptography`_) or argon2id via `argon2_cffi`_.
+
+Changelog
+=========
+
+Unreleased
+----------
+
+* Dropped support for Python 3.7.
+* We now support free-threaded Python 3.13.
+* We now support PyPy 3.11.
+* We now publish wheels for free-threaded Python 3.13, for PyPy 3.11 on
+  ``manylinux``, and for ARMv7l on ``manylinux``.
+
+4.2.1
+-----
+
+* Bump Rust dependency versions - this should resolve crashes on Python 3.13
+  free-threaded builds.
+* We no longer build ``manylinux`` wheels for PyPy 3.9.
+
+4.2.0
+-----
+
+* Bump Rust dependency versions
+* Removed the ``BCRYPT_ALLOW_RUST_163`` environment variable.
+
+4.1.3
+-----
+
+* Bump Rust dependency versions
+
+4.1.2
+-----
+
+* Publish both ``py37`` and ``py39`` wheels. This should resolve some errors
+  relating to initializing a module multiple times per process.
+
+4.1.1
+-----
+
+* Fixed the type signature on the ``kdf`` method.
+* Fixed packaging bug on Windows.
+* Fixed incompatibility with passlib package detection assumptions.
+
+4.1.0
+-----
+
+* Dropped support for Python 3.6.
+* Bumped MSRV to 1.64. (Note: Rust 1.63 can be used by setting the ``BCRYPT_ALLOW_RUST_163`` environment variable)
+
+4.0.1
+-----
+
+* We now build PyPy ``manylinux`` wheels.
+* Fixed a bug where passing an invalid ``salt`` to ``checkpw`` could result in
+  a ``pyo3_runtime.PanicException``. It now correctly raises a ``ValueError``.
+
+4.0.0
+-----
+
+* ``bcrypt`` is now implemented in Rust. Users building from source will need
+  to have a Rust compiler available. Nothing will change for users downloading
+  wheels.
+* We no longer ship ``manylinux2010`` wheels. Users should upgrade to the latest
+  ``pip`` to ensure this doesn’t cause issues downloading wheels on their
+  platform. We now ship ``manylinux_2_28`` wheels for users on new enough platforms.
+* ``NUL`` bytes are now allowed in inputs.
+
+
+3.2.2
+-----
+
+* Fixed packaging of ``py.typed`` files in wheels so that ``mypy`` works.
+
+3.2.1
+-----
+
+* Added support for compilation on z/OS
+* The next release of ``bcrypt`` with be 4.0 and it will require Rust at
+  compile time, for users building from source. There will be no additional
+  requirement for users who are installing from wheels. Users on most
+  platforms will be able to obtain a wheel by making sure they have an up to
+  date ``pip``. The minimum supported Rust version will be 1.56.0.
+* This will be the final release for which we ship ``manylinux2010`` wheels.
+  Going forward the minimum supported manylinux ABI for our wheels will be
+  ``manylinux2014``. The vast majority of users will continue to receive
+  ``manylinux`` wheels provided they have an up to date ``pip``.
+
+
+3.2.0
+-----
+
+* Added typehints for library functions.
+* Dropped support for Python versions less than 3.6 (2.7, 3.4, 3.5).
+* Shipped ``abi3`` Windows wheels (requires pip >= 20).
+
+3.1.7
+-----
+
+* Set a ``setuptools`` lower bound for PEP517 wheel building.
+* We no longer distribute 32-bit ``manylinux1`` wheels. Continuing to produce
+  them was a maintenance burden.
+
+3.1.6
+-----
+
+* Added support for compilation on Haiku.
+
+3.1.5
+-----
+
+* Added support for compilation on AIX.
+* Dropped Python 2.6 and 3.3 support.
+* Switched to using ``abi3`` wheels for Python 3. If you are not getting a
+  wheel on a compatible platform please upgrade your ``pip`` version.
+
+3.1.4
+-----
+
+* Fixed compilation with mingw and on illumos.
+
+3.1.3
+-----
+* Fixed a compilation issue on Solaris.
+* Added a warning when using too few rounds with ``kdf``.
+
+3.1.2
+-----
+* Fixed a compile issue affecting big endian platforms.
+* Fixed invalid escape sequence warnings on Python 3.6.
+* Fixed building in non-UTF8 environments on Python 2.
+
+3.1.1
+-----
+* Resolved a ``UserWarning`` when used with ``cffi`` 1.8.3.
+
+3.1.0
+-----
+* Added support for ``checkpw``, a convenience method for verifying a password.
+* Ensure that you get a ``$2y$`` hash when you input a ``$2y$`` salt.
+* Fixed a regression where ``$2a`` hashes were vulnerable to a wraparound bug.
+* Fixed compilation under Alpine Linux.
+
+3.0.0
+-----
+* Switched the C backend to code obtained from the OpenBSD project rather than
+  openwall.
+* Added support for ``bcrypt_pbkdf`` via the ``kdf`` function.
+
+2.0.0
+-----
+* Added support for an adjustible prefix when calling ``gensalt``.
+* Switched to CFFI 1.0+
+
+Usage
+-----
+
+Password Hashing
+~~~~~~~~~~~~~~~~
+
+Hashing and then later checking that a password matches the previous hashed
+password is very simple:
+
+.. code:: pycon
+
+    >>> import bcrypt
+    >>> password = b"super secret password"
+    >>> # Hash a password for the first time, with a randomly-generated salt
+    >>> hashed = bcrypt.hashpw(password, bcrypt.gensalt())
+    >>> # Check that an unhashed password matches one that has previously been
+    >>> # hashed
+    >>> if bcrypt.checkpw(password, hashed):
+    ...     print("It Matches!")
+    ... else:
+    ...     print("It Does not Match :(")
+
+KDF
+~~~
+
+As of 3.0.0 ``bcrypt`` now offers a ``kdf`` function which does ``bcrypt_pbkdf``.
+This KDF is used in OpenSSH's newer encrypted private key format.
+
+.. code:: pycon
+
+    >>> import bcrypt
+    >>> key = bcrypt.kdf(
+    ...     password=b'password',
+    ...     salt=b'salt',
+    ...     desired_key_bytes=32,
+    ...     rounds=100)
+
+
+Adjustable Work Factor
+~~~~~~~~~~~~~~~~~~~~~~
+One of bcrypt's features is an adjustable logarithmic work factor. To adjust
+the work factor merely pass the desired number of rounds to
+``bcrypt.gensalt(rounds=12)`` which defaults to 12):
+
+.. code:: pycon
+
+    >>> import bcrypt
+    >>> password = b"super secret password"
+    >>> # Hash a password for the first time, with a certain number of rounds
+    >>> hashed = bcrypt.hashpw(password, bcrypt.gensalt(14))
+    >>> # Check that a unhashed password matches one that has previously been
+    >>> #   hashed
+    >>> if bcrypt.checkpw(password, hashed):
+    ...     print("It Matches!")
+    ... else:
+    ...     print("It Does not Match :(")
+
+
+Adjustable Prefix
+~~~~~~~~~~~~~~~~~
+
+Another one of bcrypt's features is an adjustable prefix to let you define what
+libraries you'll remain compatible with. To adjust this, pass either ``2a`` or
+``2b`` (the default) to ``bcrypt.gensalt(prefix=b"2b")`` as a bytes object.
+
+As of 3.0.0 the ``$2y$`` prefix is still supported in ``hashpw`` but deprecated.
+
+Maximum Password Length
+~~~~~~~~~~~~~~~~~~~~~~~
+
+The bcrypt algorithm only handles passwords up to 72 characters, any characters
+beyond that are ignored. To work around this, a common approach is to hash a
+password with a cryptographic hash (such as ``sha256``) and then base64
+encode it to prevent NULL byte problems before hashing the result with
+``bcrypt``:
+
+.. code:: pycon
+
+    >>> password = b"an incredibly long password" * 10
+    >>> hashed = bcrypt.hashpw(
+    ...     base64.b64encode(hashlib.sha256(password).digest()),
+    ...     bcrypt.gensalt()
+    ... )
+
+Compatibility
+-------------
+
+This library should be compatible with py-bcrypt and it will run on Python
+3.8+ (including free-threaded builds), and PyPy 3.
+
+Security
+--------
+
+``bcrypt`` follows the `same security policy as cryptography`_, if you
+identify a vulnerability, we ask you to contact us privately.

+# Blinker
+
+Blinker provides a fast dispatching system that allows any number of
+interested parties to subscribe to events, or "signals".

+
+## Example
+
+Signal receivers can subscribe to specific senders or receive signals
+sent by any sender.
+
+```pycon
+>>> from blinker import signal
+>>> started = signal('round-started')
+>>> def each(round):
+...     print(f"Round {round}")
+...
+>>> started.connect(each)
+
+>>> def round_two(round):
+...     print("This is round two.")
+...
+>>> started.connect(round_two, sender=2)
+
+>>> for round in range(1, 4):
+...     started.send(round)
+...
+Round 1!
+Round 2!
+This is round two.
+Round 3!
+```

+Certifi: Python SSL Certificates
+================================
+
+Certifi provides Mozilla's carefully curated collection of Root Certificates for
+validating the trustworthiness of SSL certificates while verifying the identity
+of TLS hosts. It has been extracted from the `Requests`_ project.
+
+Installation
+------------
+
+``certifi`` is available on PyPI. Simply install it with ``pip``::
+
+    $ pip install certifi
+
+Usage
+-----
+
+To reference the installed certificate authority (CA) bundle, you can use the
+built-in function::
+
+    >>> import certifi
+
+    >>> certifi.where()
+    '/usr/local/lib/python3.7/site-packages/certifi/cacert.pem'
+
+Or from the command line::
+
+    $ python -m certifi
+    /usr/local/lib/python3.7/site-packages/certifi/cacert.pem
+
+Enjoy!
+
+.. _`Requests`: https://requests.readthedocs.io/en/master/
+
+Addition/Removal of Certificates
+--------------------------------
+
+Certifi does not support any addition/removal or other modification of the
+CA trust store content. This project is intended to provide a reliable and
+highly portable root of trust to python deployments. Look to upstream projects
+for methods to use alternate trust.

+/* We try to define Py_LIMITED_API before including Python.h.
+
+   Mess: we can only define it if Py_DEBUG, Py_TRACE_REFS and
+   Py_REF_DEBUG are not defined.  This is a best-effort approximation:
+   we can learn about Py_DEBUG from pyconfig.h, but it is unclear if
+   the same works for the other two macros.  Py_DEBUG implies them,
+   but not the other way around.
+
+   The implementation is messy (issue #350): on Windows, with _MSC_VER,
+   we have to define Py_LIMITED_API even before including pyconfig.h.
+   In that case, we guess what pyconfig.h will do to the macros above,
+   and check our guess after the #include.
+
+   Note that on Windows, with CPython 3.x, you need >= 3.5 and virtualenv
+   version >= 16.0.0.  With older versions of either, you don't get a
+   copy of PYTHON3.DLL in the virtualenv.  We can't check the version of
+   CPython *before* we even include pyconfig.h.  ffi.set_source() puts
+   a ``#define _CFFI_NO_LIMITED_API'' at the start of this file if it is
+   running on Windows < 3.5, as an attempt at fixing it, but that's
+   arguably wrong because it may not be the target version of Python.
+   Still better than nothing I guess.  As another workaround, you can
+   remove the definition of Py_LIMITED_API here.

+       completely concurrently from unrelated threads.  It assumes
+       that we don't hold the GIL before (if it exists), and we don't
+       hold it afterwards.
+
+       (What it really does used to be completely different in Python 2
+       and Python 3, with the Python 2 solution avoiding the spin-lock
+       around the Py_InitializeEx() call.  However, after recent changes
+       to CPython 2.7 (issue #358) it no longer works.  So we use the
+       Python 3 solution everywhere.)
+
+       This initializes Python by calling Py_InitializeEx().
+       Important: this must not be called concurrently at all.
+       So we use a global variable as a simple spin lock.  This global
+       variable must be from 'libpythonX.Y.so', not from this
+       cffi-based extension module, because it must be shared from
+       different cffi-based extension modules.
+
+       In Python < 3.8, we choose
+       _PyParser_TokenNames[0] as a completely arbitrary pointer value
+       that is never written to.  The default is to point to the
+       string "ENDMARKER".  We change it temporarily to point to the
+       next character in that string.  (Yes, I know it's REALLY
+       obscure.)
+
+       In Python >= 3.8, this string array is no longer writable, so
+       instead we pick PyCapsuleType.tp_version_tag.  We can't change
+       Python < 3.8 because someone might use a mixture of cffi
+       embedded modules, some of which were compiled before this file
+       changed.
+
+       In Python >= 3.12, this stopped working because that particular
+       tp_version_tag gets modified during interpreter startup.  It's
+       arguably a bad idea before 3.12 too, but again we can't change
+       that because someone might use a mixture of cffi embedded
+       modules, and no-one reported a bug so far.  In Python >= 3.12
+       we go instead for PyCapsuleType.tp_as_buffer, which is supposed
+       to always be NULL.  We write to it temporarily a pointer to
+       a struct full of NULLs, which is semantically the same.

+## ⚡ Performance
+
+This package offer better performance than its counterpart Chardet. Here are some numbers.
+
+| Package                                       | Accuracy | Mean per file (ms) | File per sec (est) |
+|-----------------------------------------------|:--------:|:------------------:|:------------------:|
+| [chardet](https://github.com/chardet/chardet) |   86 %   |       63 ms        |    16 file/sec     |
+| charset-normalizer                            | **98 %** |     **10 ms**      |    100 file/sec    |
+
+| Package                                       | 99th percentile | 95th percentile | 50th percentile |
+|-----------------------------------------------|:---------------:|:---------------:|:---------------:|
+| [chardet](https://github.com/chardet/chardet) |     265 ms      |      71 ms      |      7 ms       |
+| charset-normalizer                            |     100 ms      |      50 ms      |      5 ms       |
+
+_updated as of december 2024 using CPython 3.12_
+
+Chardet's performance on larger file (1MB+) are very poor. Expect huge difference on large payload.
+
+> Stats are generated using 400+ files using default parameters. More details on used files, see GHA workflows.
+> And yes, these results might change at any time. The dataset can be updated to include more files.
+> The actual delays heavily depends on your CPU capabilities. The factors should remain the same.
+> Keep in mind that the stats are generous and that Chardet accuracy vs our is measured using Chardet initial capability
+> (e.g. Supported Encoding) Challenge-them if you want.
+
+## ✨ Installation
+
+Using pip:
+
+```sh
+pip install charset-normalizer -U
+```
+
+## 🚀 Basic Usage
+
+### CLI
+This package comes with a CLI.
+
+```
+usage: normalizer [-h] [-v] [-a] [-n] [-m] [-r] [-f] [-t THRESHOLD]
+                  file [file ...]
+
+The Real First Universal Charset Detector. Discover originating encoding used
+on text file. Normalize text to unicode.
+
+positional arguments:
+  files                 File(s) to be analysed
+
+optional arguments:
+  -h, --help            show this help message and exit
+  -v, --verbose         Display complementary information about file if any.
+                        Stdout will contain logs about the detection process.
+  -a, --with-alternative
+                        Output complementary possibilities if any. Top-level
+                        JSON WILL be a list.
+  -n, --normalize       Permit to normalize input file. If not set, program
+                        does not write anything.
+  -m, --minimal         Only output the charset detected to STDOUT. Disabling
+                        JSON output.
+  -r, --replace         Replace file when trying to normalize it instead of
+                        creating a new one.
+  -f, --force           Replace file without asking if you are sure, use this
+                        flag with caution.
+  -t THRESHOLD, --threshold THRESHOLD
+                        Define a custom maximum amount of chaos allowed in
+                        decoded content. 0. <= chaos <= 1.
+  --version             Show version information and exit.
+```
+
+```bash
+normalizer ./data/sample.1.fr.srt
+```
+
+or
+
+```bash
+python -m charset_normalizer ./data/sample.1.fr.srt
+```
+
+🎉 Since version 1.4.0 the CLI produce easily usable stdout result in JSON format.

+### Python
+*Just print out normalized text*
+```python
+from charset_normalizer import from_path
+
+results = from_path('./my_subtitle.srt')
+
+print(str(results.best()))
+```
+
+*Upgrade your code without effort*
+```python
+from charset_normalizer import detect
+```
+
+The above code will behave the same as **chardet**. We ensure that we offer the best (reasonable) BC result possible.
+
+See the docs for advanced usage : [readthedocs.io](https://charset-normalizer.readthedocs.io/en/latest/)
+
+## 😇 Why
+
+When I started using Chardet, I noticed that it was not suited to my expectations, and I wanted to propose a
+reliable alternative using a completely different method. Also! I never back down on a good challenge!
+
+I **don't care** about the **originating charset** encoding, because **two different tables** can
+produce **two identical rendered string.**
+What I want is to get readable text, the best I can.
+
+In a way, **I'm brute forcing text decoding.** How cool is that ? 😎
+
+Don't confuse package **ftfy** with charset-normalizer or chardet. ftfy goal is to repair Unicode string whereas charset-normalizer to convert raw file in unknown encoding to unicode.
+
+## 🍰 How
+
+  - Discard all charset encoding table that could not fit the binary content.
+  - Measure noise, or the mess once opened (by chunks) with a corresponding charset encoding.
+  - Extract matches with the lowest mess detected.
+  - Additionally, we measure coherence / probe for a language.
+
+**Wait a minute**, what is noise/mess and coherence according to **YOU ?**
+
+*Noise :* I opened hundred of text files, **written by humans**, with the wrong encoding table. **I observed**, then
+**I established** some ground rules about **what is obvious** when **it seems like** a mess (aka. defining noise in rendered text).
+ I know that my interpretation of what is noise is probably incomplete, feel free to contribute in order to
+ improve or rewrite it.
+
+*Coherence :* For each language there is on earth, we have computed ranked letter appearance occurrences (the best we can). So I thought
+that intel is worth something here. So I use those records against decoded text to check if I can detect intelligent design.
+
+## ⚡ Known limitations
+
+  - Language detection is unreliable when text contains two or more languages sharing identical letters. (eg. HTML (english tags) + Turkish content (Sharing Latin characters))
+  - Every charset detector heavily depends on sufficient content. In common cases, do not bother run detection on very tiny content.
+

+"""
+Charset-Normalizer
+~~~~~~~~~~~~~~
+The Real First Universal Charset Detector.
+A library that helps you read text from an unknown charset encoding.
+Motivated by chardet, This package is trying to resolve the issue by taking a new approach.
+All IANA character set names for which the Python core library provides codecs are supported.
+
+Basic usage:
+   >>> from charset_normalizer import from_bytes
+   >>> results = from_bytes('Bсеки човек има право на образование. Oбразованието!'.encode('utf_8'))
+   >>> best_guess = results.best()
+   >>> str(best_guess)
+   'Bсеки човек има право на образование. Oбразованието!'
+
+Others methods and usages are available - see the full documentation
+at <https://github.com/Ousret/charset_normalizer>.

+# $ click_
+
+Click is a Python package for creating beautiful command line interfaces
+in a composable way with as little code as necessary. It's the "Command
+Line Interface Creation Kit". It's highly configurable but comes with
+sensible defaults out of the box.
+
+It aims to make the process of writing command line tools quick and fun
+while also preventing any frustration caused by the inability to
+implement an intended CLI API.
+
+Click in three points:
+
+-   Arbitrary nesting of commands
+-   Automatic help page generation
+-   Supports lazy loading of subcommands at runtime
+
+
+## A Simple Example
+
+```python
+import click
+
+@click.command()
+@click.option("--count", default=1, help="Number of greetings.")
+@click.option("--name", prompt="Your name", help="The person to greet.")
+def hello(count, name):
+    """Simple program that greets NAME for a total of COUNT times."""
+    for _ in range(count):
+        click.echo(f"Hello, {name}!")
+
+if __name__ == '__main__':
+    hello()
+```
+
+```
+$ python hello.py --count=3
+Your name: Click
+Hello, Click!
+Hello, Click!
+Hello, Click!
+```

+
+    A context can be used as context manager in which case it will call

+

+                      is the most descriptive name for the script or
+                      command.  For the toplevel script it is usually

+                               from environment variables is disabled.  This

+                               variables which are always read.
+    :param default_map: a dictionary (like object) with default values
+                        for parameters.
+    :param terminal_width: the width of the terminal.  The default is
+                           inherit from parent context.  If no context
+                           defines the terminal width then auto

+                              pages).  This defaults to 80 characters if
+                              not overridden.  In other words: even if the
+                              terminal is larger than that, Click will not
+                              format things wider than 80 characters by

+                              add some safety mapping on the right.
+    :param resilient_parsing: if this flag is enabled then Click will
+                              parse without any interactivity or callback
+                              invocation.  Default values will also be

+    :param allow_extra_args: if this is set to `True` then extra arguments
+                             at the end will not raise an error and will be
+                             kept on the context.  The default is to inherit
+                             from the command.

+                                    and arguments cannot be mixed.  The
+                                    default is to inherit from the command.

+                                   not know and keeps them for later
+                                   processing.
+    :param help_option_names: optionally a list of strings that define how
+                              the default help parameter is named.  The
+                              default is ``['--help']``.

+                                 etc.).  This for instance can be used to
+                                 implement case insensitive behavior.
+    :param color: controls if the terminal supports ANSI colors or not.  The
+                  default is autodetection.  This is only needed if ANSI
+                  codes are used in texts that Click prints which is by
+                  default not the case.  This for instance would affect
+                  help output.
+    :param show_default: Show the default value for commands. If this
+        value is not set, it defaults to the value from the parent

+        specific command.

+

+

+                        argument.  This is a list of flags or argument
+                        names.
+    :param type: the type that should be used.  Either a :class:`ParamType`
+                 or a Python type.  The latter is converted into the former
+                 automatically if supported.

+                    without any arguments.
+    :param callback: A function to further process or validate the value
+        after type conversion. It is called as ``f(ctx, param, value)``
+        and must return the value. It is called for all sources,
+        including prompts.
+    :param nargs: the number of arguments to match.  If not ``1`` the return
+                  value is a tuple instead of single value.  The default for
+                  nargs is ``1`` (except if the type is a tuple, then it's
+                  the arity of the tuple). If ``nargs=-1``, all remaining
+                  parameters are collected.
+    :param metavar: how the value is represented in the help page.
+    :param expose_value: if this is `True` then the value is passed onwards
+                         to the command callback and stored on the context,
+                         otherwise it's skipped.
+    :param is_eager: eager values are processed before non eager ones.  This
+                     should not be set for arguments or it will inverse the
+                     order of processing.
+    :param envvar: a string or list of strings that are environment variables
+                   that should be checked.
+    :param shell_complete: A function that returns custom shell
+        completions. Used instead of the param's type completion if
+        given. Takes ``ctx, param, incomplete`` and must return a list
+        of :class:`~click.shell_completion.CompletionItem` or a list of

+                        its deprecation in --help. The message can be customized

+
+    .. versionchanged:: 8.0
+        ``process_value`` validates required parameters and bounded
+        ``nargs``, and invokes the parameter callback before returning
+        the value. This allows the callback to validate prompts.
+        ``full_process_value`` is removed.

+        tuples.
+
+    .. versionchanged:: 8.0
+        Setting a default is no longer required for ``nargs>1``, it will
+        default to ``None``. ``multiple=True`` or ``nargs=-1`` will
+        default to ``()``.
+
+    .. versionchanged:: 7.1
+        Empty environment variables are ignored rather than taking the

+        Changed signature for parameter callback to also be passed the

+This module started out as largely a copy paste from the stdlib's
+optparse module with the features removed that we do not need from
+optparse because we implement them in Click on a higher level (for
+instance type handling, help formatting and a lot more).
+
+The plan is to remove more and more from here over time.
+
+The reason this is a different module and not optparse from the stdlib
+is that there are differences in 2.x and 3.x about the error messages
+generated and optparse in the stdlib uses gettext for no good reason
+and might cause us issues.
+
+Click uses parts of optparse written by Gregory P. Ward and maintained
+by the Python Software Foundation. This is limited to code in parser.py.

+    """This function creates an iterable context manager that can be used
+    to iterate over something while showing a progress bar.  It will
+    either iterate over the `iterable` or `length` items (that are counted
+    up).  While iteration happens, this function will print a rendered
+    progress bar to the given `file` (defaults to stdout) and will attempt
+    to calculate remaining time and more.  By default, this progress bar
+    will not be rendered if the file is not a terminal.
+
+    The context manager creates the progress bar.  When the context
+    manager is entered the progress bar is already created.  With every
+    iteration over the progress bar, the iterable passed to the bar is
+    advanced and the bar is updated.  When the context manager exits,
+    a newline is printed and the progress bar is finalized on screen.
+
+    Note: The progress bar is currently designed for use cases where the
+    total progress can be expected to take at least several seconds.
+    Because of this, the ProgressBar class object won't display
+    progress that is considered too fast, and progress where the time
+    between steps is less than a second.
+
+    No printing must happen or the progress bar will be unintentionally
+    destroyed.
+
+    Example usage::
+
+        with progressbar(items) as bar:
+            for item in bar:
+                do_something_with(item)
+
+    Alternatively, if no iterable is specified, one can manually update the
+    progress bar through the `update()` method instead of directly
+    iterating over the progress bar.  The update method accepts the number
+    of steps to increment the bar with::
+
+        with progressbar(length=chunks.total_bytes) as bar:
+            for chunk in chunks:
+                process_chunk(chunk)
+                bar.update(chunks.bytes)
+
+    The ``update()`` method also takes an optional value specifying the
+    ``current_item`` at the new position. This is useful when used
+    together with ``item_show_func`` to customize the output for each
+    manual step::
+
+        with click.progressbar(
+            length=total_size,
+            label='Unzipping archive',
+            item_show_func=lambda a: a.filename
+        ) as bar:
+            for archive in zip_file:
+                archive.extract()
+                bar.update(archive.size, archive)
+
+    :param iterable: an iterable to iterate over.  If not provided the length
+                     is required.
+    :param length: the number of items to iterate over.  By default the
+                   progressbar will attempt to ask the iterator about its
+                   length, which might or might not work.  If an iterable is
+                   also provided this parameter can be used to override the
+                   length.  If an iterable is not provided the progress bar
+                   will iterate over a range of that length.
+    :param label: the label to show next to the progress bar.
+    :param hidden: hide the progressbar. Defaults to ``False``. When no tty is
+        detected, it will only print the progressbar label. Setting this to
+        ``False`` also disables that.
+    :param show_eta: enables or disables the estimated time display.  This is
+                     automatically disabled if the length cannot be
+                     determined.
+    :param show_percent: enables or disables the percentage display.  The
+                         default is `True` if the iterable has a length or
+                         `False` if not.
+    :param show_pos: enables or disables the absolute position display.  The
+                     default is `False`.
+    :param item_show_func: A function called with the current item which
+        can return a string to show next to the progress bar. If the
+        function returns ``None`` nothing is shown. The current item can
+        be ``None``, such as when entering and exiting the bar.
+    :param fill_char: the character to use to show the filled part of the
+                      progress bar.
+    :param empty_char: the character to use to show the non-filled part of
+                       the progress bar.
+    :param bar_template: the format string to use as template for the bar.
+                         The parameters in it are ``label`` for the label,
+                         ``bar`` for the progress bar and ``info`` for the
+                         info section.
+    :param info_sep: the separator between multiple info items (eta etc.)
+    :param width: the width of the progress bar in characters, 0 means full
+                  terminal width
+    :param file: The file to write to. If this is not a terminal then
+        only the label is printed.
+    :param color: controls if the terminal supports ANSI colors or not.  The
+                  default is autodetection.  This is only needed if ANSI
+                  codes are included anywhere in the progress bar output
+                  which is not the case by default.
+    :param update_min_steps: Render only when this many updates have
+        completed. This allows tuning for very fast iterators.

+
+
+``cryptography`` is a package which provides cryptographic recipes and
+primitives to Python developers. Our goal is for it to be your "cryptographic
+standard library". It supports Python 3.7+ and PyPy3 7.3.11+.
+
+``cryptography`` includes both high level recipes and low level interfaces to
+common cryptographic algorithms such as symmetric ciphers, message digests, and
+key derivation functions. For example, to encrypt something with
+``cryptography``'s high level symmetric encryption recipe:
+
+.. code-block:: pycon
+
+    >>> from cryptography.fernet import Fernet
+    >>> # Put this somewhere safe!
+    >>> key = Fernet.generate_key()
+    >>> f = Fernet(key)
+    >>> token = f.encrypt(b"A really secret message. Not for prying eyes.")
+    >>> token
+    b'...'
+    >>> f.decrypt(token)
+    b'A really secret message. Not for prying eyes.'
+
+You can find more information in the `documentation`_.
+
+You can install ``cryptography`` with:
+
+.. code-block:: console
+
+    $ pip install cryptography
+
+For full details see `the installation documentation`_.
+
+Discussion
+~~~~~~~~~~
+
+If you run into bugs, you can file them in our `issue tracker`_.
+
+We maintain a `cryptography-dev`_ mailing list for development discussion.
+
+You can also join ``#pyca`` on ``irc.libera.chat`` to ask questions or get
+involved.

+
+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.
+
+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the
+      outstanding shares, or (iii) beneficial ownership of such entity.
+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "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
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   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,
+      where such license applies only to those patent claims licensable
+      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.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.

+# Flask
+
+Flask is a lightweight [WSGI] web application framework. It is designed
+to make getting started quick and easy, with the ability to scale up to
+complex applications. It began as a simple wrapper around [Werkzeug]
+and [Jinja], and has become one of the most popular Python web
+application frameworks.
+
+Flask offers suggestions, but doesn't enforce any dependencies or
+project layout. It is up to the developer to choose the tools and
+libraries they want to use. There are many extensions provided by the
+community that make adding new functionality easy.
+
+[WSGI]: https://wsgi.readthedocs.io/
+[Werkzeug]: https://werkzeug.palletsprojects.com/
+[Jinja]: https://jinja.palletsprojects.com/
+
+## A Simple Example
+
+```python
+# save this as app.py
+from flask import Flask
+
+app = Flask(__name__)
+
+@app.route("/")
+def hello():
+    return "Hello, World!"
+```
+
+```
+$ flask run
+  * Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)
+```

+class Flask(App):
+    """The flask object implements a WSGI application and acts as the central
+    object.  It is passed the name of the module or package of the
+    application.  Once it is created it will act as a central registry for
+    the view functions, the URL rules, template configuration and much more.
+
+    The name of the package is used to resolve resources from inside the
+    package or the folder the module is contained in depending on if the
+    package parameter resolves to an actual python package (a folder with
+    an :file:`__init__.py` file inside) or a standard module (just a ``.py`` file).
+
+    For more information about resource loading, see :func:`open_resource`.
+
+    Usually you create a :class:`Flask` instance in your main module or
+    in the :file:`__init__.py` file of your package like this::
+
+        from flask import Flask
+        app = Flask(__name__)
+
+    .. admonition:: About the First Parameter
+
+        The idea of the first parameter is to give Flask an idea of what
+        belongs to your application.  This name is used to find resources
+        on the filesystem, can be used by extensions to improve debugging
+        information and a lot more.
+
+        So it's important what you provide there.  If you are using a single
+        module, `__name__` is always the correct value.  If you however are
+        using a package, it's usually recommended to hardcode the name of
+        your package there.
+
+        For example if your application is defined in :file:`yourapplication/app.py`
+        you should create it with one of the two versions below::
+
+            app = Flask('yourapplication')
+            app = Flask(__name__.split('.')[0])
+
+        Why is that?  The application will work even with `__name__`, thanks
+        to how resources are looked up.  However it will make debugging more
+        painful.  Certain extensions can make assumptions based on the
+        import name of your application.  For example the Flask-SQLAlchemy
+        extension will look for the code in your application that triggered
+        an SQL query in debug mode.  If the import name is not properly set
+        up, that debugging information is lost.  (For example it would only
+        pick up SQL queries in `yourapplication.app` and not
+        `yourapplication.views.frontend`)

+    :param static_folder: The folder with static files that is served at
+        ``static_url_path``. Relative to the application ``root_path``
+        or an absolute path. Defaults to ``'static'``.
+    :param static_host: the host to use when adding the static route.
+        Defaults to None. Required when using ``host_matching=True``
+        with a ``static_folder`` configured.
+    :param host_matching: set ``url_map.host_matching`` attribute.
+        Defaults to False.
+    :param subdomain_matching: consider the subdomain relative to
+        :data:`SERVER_NAME` when matching routes. Defaults to False.
+    :param template_folder: the folder that contains the templates that should
+                            be used by the application.  Defaults to
+                            ``'templates'`` folder in the root path of the
+                            application.
+    :param instance_path: An alternative instance path for the application.
+                          By default the folder ``'instance'`` next to the
+                          package or module is assumed to be the instance
+                          path.
+    :param instance_relative_config: if set to ``True`` relative filenames
+                                     for loading the config are assumed to
+                                     be relative to the instance path instead
+                                     of the application root.
+    :param root_path: The path to the root of the application files.
+        This should only be set manually when it can't be detected
+        automatically, such as for namespace packages.

+        the scheme and domain, like ``https://example.com/hello``. When
+        not in an active request, URLs will be external by default, but
+        this requires setting :data:`SERVER_NAME` so Flask knows what

+        :data:`PREFERRED_URL_SCHEME` should also be configured as
+        needed. This config is only used when not in an active request.
+
+        Functions can be decorated with :meth:`url_defaults` to modify
+        keyword arguments before the URL is built.
+
+        If building fails for some reason, such as an unknown endpoint
+        or incorrect values, the app's :meth:`handle_url_build_error`
+        method is called. If that returns a string, that is returned,

+            generate. If this starts with a ``.``, the current blueprint
+            name (if any) will be used.

+        :param _method: If given, generate the URL associated with this
+            method for the endpoint.
+        :param _scheme: If given, the URL will have this scheme if it

+    """Works exactly like a dict but provides ways to fill it from files

+
+    Either you can fill the config from a config file::
+
+        app.config.from_pyfile('yourconfig.cfg')
+
+    Or alternatively you can define the configuration options in the
+    module that calls :meth:`from_object` or provide an import path to
+    a module that should be loaded.  It is also possible to tell it to
+    use the same module and with that provide the configuration values
+    just before the call::
+
+        DEBUG = True
+        SECRET_KEY = 'development key'
+        app.config.from_object(__name__)
+
+    In both cases (loading from any Python file or loading from modules),
+    only uppercase keys are added to the config.  This makes it possible to use
+    lowercase values in the config file for temporary values that are not added
+    to the config or to define the config keys in the same file that implements
+    the application.
+
+    Probably the most interesting way to load configurations is from an
+    environment variable pointing to a file::
+

+    """The flask object implements a WSGI application and acts as the central
+    object.  It is passed the name of the module or package of the
+    application.  Once it is created it will act as a central registry for
+    the view functions, the URL rules, template configuration and much more.
+
+    The name of the package is used to resolve resources from inside the
+    package or the folder the module is contained in depending on if the
+    package parameter resolves to an actual python package (a folder with
+    an :file:`__init__.py` file inside) or a standard module (just a ``.py`` file).
+
+    For more information about resource loading, see :func:`open_resource`.
+
+    Usually you create a :class:`Flask` instance in your main module or
+    in the :file:`__init__.py` file of your package like this::
+
+        from flask import Flask
+        app = Flask(__name__)
+
+    .. admonition:: About the First Parameter
+
+        The idea of the first parameter is to give Flask an idea of what
+        belongs to your application.  This name is used to find resources
+        on the filesystem, can be used by extensions to improve debugging
+        information and a lot more.
+
+        So it's important what you provide there.  If you are using a single
+        module, `__name__` is always the correct value.  If you however are
+        using a package, it's usually recommended to hardcode the name of
+        your package there.
+
+        For example if your application is defined in :file:`yourapplication/app.py`
+        you should create it with one of the two versions below::
+
+            app = Flask('yourapplication')
+            app = Flask(__name__.split('.')[0])
+
+        Why is that?  The application will work even with `__name__`, thanks
+        to how resources are looked up.  However it will make debugging more
+        painful.  Certain extensions can make assumptions based on the
+        import name of your application.  For example the Flask-SQLAlchemy
+        extension will look for the code in your application that triggered
+        an SQL query in debug mode.  If the import name is not properly set
+        up, that debugging information is lost.  (For example it would only
+        pick up SQL queries in `yourapplication.app` and not
+        `yourapplication.views.frontend`)
+
+    .. versionadded:: 0.7
+       The `static_url_path`, `static_folder`, and `template_folder`

+    :param static_host: the host to use when adding the static route.
+        Defaults to None. Required when using ``host_matching=True``

+        Defaults to False.

+    Decorating a function with a blueprint creates a deferred function
+    that is called with :class:`~flask.blueprints.BlueprintSetupState`
+    when the blueprint is registered on an application.
+
+    See :doc:`/blueprints` for more information.
+
+    :param name: The name of the blueprint. Will be prepended to each
+        endpoint name.
+    :param import_name: The name of the blueprint package, usually
+        ``__name__``. This helps locate the ``root_path`` for the
+        blueprint.
+    :param static_folder: A folder with static files that should be
+        served by the blueprint's static route. The path is relative to
+        the blueprint's root path. Blueprint static files are disabled
+        by default.
+    :param static_url_path: The url to serve static files from.
+        Defaults to ``static_folder``. If the blueprint does not have
+        a ``url_prefix``, the app's static route will take precedence,
+        and the blueprint's static files won't be accessible.
+    :param template_folder: A folder with templates that should be added
+        to the app's template search path. The path is relative to the
+        blueprint's root path. Blueprint templates are disabled by
+        default. Blueprint templates have a lower precedence than those
+        in the app's templates folder.
+    :param url_prefix: A path to prepend to all of the blueprint's URLs,
+        to make them distinct from the rest of the app's routes.
+    :param subdomain: A subdomain that blueprint routes will match on by
+        default.
+    :param url_defaults: A dict of default values that blueprint routes
+        will receive by default.
+    :param root_path: By default, the blueprint will automatically set
+        this based on ``import_name``. In certain situations this
+        automatic detection can fail, so the path can be specified
+        manually instead.

+Gunicorn 'Green Unicorn' is a Python WSGI HTTP Server for UNIX. It's a pre-fork
+worker model ported from Ruby's Unicorn_ project. The Gunicorn server is broadly
+compatible with various web frameworks, simply implemented, light on server
+resource usage, and fairly speedy.
+
+Feel free to join us in `#gunicorn`_ on `Libera.chat`_.
+
+Documentation
+-------------
+
+The documentation is hosted at https://docs.gunicorn.org.
+
+Installation
+------------
+
+Gunicorn requires **Python 3.x >= 3.7**.
+
+Install from PyPI::
+
+    $ pip install gunicorn
+
+
+Usage
+-----
+
+Basic usage::
+
+    $ gunicorn [OPTIONS] APP_MODULE
+
+Where ``APP_MODULE`` is of the pattern ``$(MODULE_NAME):$(VARIABLE_NAME)``. The
+module name can be a full dotted path. The variable name refers to a WSGI
+callable that should be found in the specified module.
+
+Example with test app::
+
+    $ cd examples
+    $ gunicorn --workers=2 test:app
+
+
+Contributing
+------------
+
+See `our complete contributor's guide <CONTRIBUTING.md>`_ for more details.
+
+
+License
+-------

+Internationalized Domain Names in Applications (IDNA)
+=====================================================
+
+Support for the Internationalized Domain Names in
+Applications (IDNA) protocol as specified in `RFC 5891
+<https://tools.ietf.org/html/rfc5891>`_. This is the latest version of
+the protocol and is sometimes referred to as “IDNA 2008”.
+
+This library also provides support for Unicode Technical
+Standard 46, `Unicode IDNA Compatibility Processing
+<https://unicode.org/reports/tr46/>`_.
+
+This acts as a suitable replacement for the “encodings.idna”
+module that comes with the Python standard library, but which
+only supports the older superseded IDNA specification (`RFC 3490
+<https://tools.ietf.org/html/rfc3490>`_).
+
+Basic functions are simply executed:
+
+.. code-block:: pycon
+
+    >>> import idna
+    >>> idna.encode('ドメイン.テスト')
+    b'xn--eckwd4c7c.xn--zckzah'
+    >>> print(idna.decode('xn--eckwd4c7c.xn--zckzah'))
+    ドメイン.テスト
+
+
+Installation
+------------
+
+This package is available for installation from PyPI:
+
+.. code-block:: bash
+
+    $ python3 -m pip install idna
+
+
+Usage
+-----
+
+For typical usage, the ``encode`` and ``decode`` functions will take a
+domain name argument and perform a conversion to A-labels or U-labels
+respectively.
+
+.. code-block:: pycon
+
+    >>> import idna
+    >>> idna.encode('ドメイン.テスト')
+    b'xn--eckwd4c7c.xn--zckzah'
+    >>> print(idna.decode('xn--eckwd4c7c.xn--zckzah'))
+    ドメイン.テスト
+
+You may use the codec encoding and decoding methods using the
+``idna.codec`` module:
+
+.. code-block:: pycon
+
+    >>> import idna.codec
+    >>> print('домен.испытание'.encode('idna2008'))
+    b'xn--d1acufc.xn--80akhbyknj4f'
+    >>> print(b'xn--d1acufc.xn--80akhbyknj4f'.decode('idna2008'))
+    домен.испытание
+
+Conversions can be applied at a per-label basis using the ``ulabel`` or
+``alabel`` functions if necessary:
+
+.. code-block:: pycon
+
+    >>> idna.alabel('测试')
+    b'xn--0zwm56d'
+
+Compatibility Mapping (UTS #46)
++++++++++++++++++++++++++++++++
+
+As described in `RFC 5895 <https://tools.ietf.org/html/rfc5895>`_, the
+IDNA specification does not normalize input from different potential
+ways a user may input a domain name. This functionality, known as
+a “mapping”, is considered by the specification to be a local
+user-interface issue distinct from IDNA conversion functionality.
+
+This library provides one such mapping that was developed by the
+Unicode Consortium. Known as `Unicode IDNA Compatibility Processing
+<https://unicode.org/reports/tr46/>`_, it provides for both a regular
+mapping for typical applications, as well as a transitional mapping to
+help migrate from older IDNA 2003 applications. Strings are
+preprocessed according to Section 4.4 “Preprocessing for IDNA2008”
+prior to the IDNA operations.
+
+For example, “Königsgäßchen” is not a permissible label as *LATIN
+CAPITAL LETTER K* is not allowed (nor are capital letters in general).
+UTS 46 will convert this into lower case prior to applying the IDNA
+conversion.
+
+.. code-block:: pycon
+
+    >>> import idna
+    >>> idna.encode('Königsgäßchen')
+    ...
+    idna.core.InvalidCodepoint: Codepoint U+004B at position 1 of 'Königsgäßchen' not allowed
+    >>> idna.encode('Königsgäßchen', uts46=True)
+    b'xn--knigsgchen-b4a3dun'
+    >>> print(idna.decode('xn--knigsgchen-b4a3dun'))
+    königsgäßchen
+
+Transitional processing provides conversions to help transition from
+the older 2003 standard to the current standard. For example, in the
+original IDNA specification, the *LATIN SMALL LETTER SHARP S* (ß) was
+converted into two *LATIN SMALL LETTER S* (ss), whereas in the current
+IDNA specification this conversion is not performed.
+
+.. code-block:: pycon
+
+    >>> idna.encode('Königsgäßchen', uts46=True, transitional=True)
+    'xn--knigsgsschen-lcb0w'
+
+Implementers should use transitional processing with caution, only in
+rare cases where conversion from legacy labels to current labels must be
+performed (i.e. IDNA implementations that pre-date 2008). For typical
+applications that just need to convert labels, transitional processing
+is unlikely to be beneficial and could produce unexpected incompatible
+results.
+
+``encodings.idna`` Compatibility
+++++++++++++++++++++++++++++++++
+
+Function calls from the Python built-in ``encodings.idna`` module are
+mapped to their IDNA 2008 equivalents using the ``idna.compat`` module.
+Simply substitute the ``import`` clause in your code to refer to the new
+module name.
+
+Exceptions
+----------
+
+All errors raised during the conversion following the specification
+should raise an exception derived from the ``idna.IDNAError`` base
+class.
+
+More specific exceptions that may be generated as ``idna.IDNABidiError``
+when the error reflects an illegal combination of left-to-right and
+right-to-left characters in a label; ``idna.InvalidCodepoint`` when
+a specific codepoint is an illegal character in an IDN label (i.e.
+INVALID); and ``idna.InvalidCodepointContext`` when the codepoint is
+illegal based on its positional context (i.e. it is CONTEXTO or CONTEXTJ
+but the contextual requirements are not satisfied.)
+
+Building and Diagnostics
+------------------------
+
+The IDNA and UTS 46 functionality relies upon pre-calculated lookup
+tables for performance. These tables are derived from computing against
+eligibility criteria in the respective standards. These tables are
+computed using the command-line script ``tools/idna-data``.
+
+This tool will fetch relevant codepoint data from the Unicode repository
+and perform the required calculations to identify eligibility. There are
+three main modes:
+
+* ``idna-data make-libdata``. Generates ``idnadata.py`` and
+  ``uts46data.py``, the pre-calculated lookup tables used for IDNA and
+  UTS 46 conversions. Implementers who wish to track this library against
+  a different Unicode version may use this tool to manually generate a
+  different version of the ``idnadata.py`` and ``uts46data.py`` files.
+
+* ``idna-data make-table``. Generate a table of the IDNA disposition
+  (e.g. PVALID, CONTEXTJ, CONTEXTO) in the format found in Appendix
+  B.1 of RFC 5892 and the pre-computed tables published by `IANA
+  <https://www.iana.org/>`_.
+
+* ``idna-data U+0061``. Prints debugging output on the various
+  properties associated with an individual Unicode codepoint (in this
+  case, U+0061), that are used to assess the IDNA and UTS 46 status of a
+  codepoint. This is helpful in debugging or analysis.
+
+The tool accepts a number of arguments, described using ``idna-data
+-h``. Most notably, the ``--version`` argument allows the specification
+of the version of Unicode to be used in computing the table data. For
+example, ``idna-data --version 9.0.0 make-libdata`` will generate
+library data against Unicode 9.0.0.
+
+
+Additional Notes
+----------------
+
+* **Packages**. The latest tagged release version is published in the
+  `Python Package Index <https://pypi.org/project/idna/>`_.
+
+* **Version support**. This library supports Python 3.6 and higher.
+  As this library serves as a low-level toolkit for a variety of
+  applications, many of which strive for broad compatibility with older
+  Python versions, there is no rush to remove older interpreter support.
+  Removing support for older versions should be well justified in that the
+  maintenance burden has become too high.
+
+* **Python 2**. Python 2 is supported by version 2.x of this library.
+  Use "idna<3" in your requirements file if you need this library for
+  a Python 2 application. Be advised that these versions are no longer
+  actively developed.
+
+* **Testing**. The library has a test suite based on each rule of the
+  IDNA specification, as well as tests that are provided as part of the
+  Unicode Technical Standard 46, `Unicode IDNA Compatibility Processing
+  <https://unicode.org/reports/tr46/>`_.
+
+* **Emoji**. It is an occasional request to support emoji domains in
+  this library. Encoding of symbols like emoji is expressly prohibited by
+  the technical standard IDNA 2008 and emoji domains are broadly phased
+  out across the domain industry due to associated security risks. For
+  now, applications that need to support these non-compliant labels
+  may wish to consider trying the encode/decode operation in this library
+  first, and then falling back to using `encodings.idna`. See `the Github
+  project <https://github.com/kjd/idna/issues/18>`_ for more discussion.

+# ItsDangerous
+
+... so better sign this
+
+Various helpers to pass data to untrusted environments and to get it
+back safe and sound. Data is cryptographically signed to ensure that a
+token has not been tampered with.
+
+It's possible to customize how data is serialized. Data is compressed as
+needed. A timestamp can be added and verified automatically while
+loading a token.
+
+
+## A Simple Example
+
+Here's how you could generate a token for transmitting a user's id and
+name between web requests.
+
+```python
+from itsdangerous import URLSafeSerializer
+auth_s = URLSafeSerializer("secret key", "auth")
+token = auth_s.dumps({"id": 5, "name": "itsdangerous"})
+
+print(token)
+# eyJpZCI6NSwibmFtZSI6Iml0c2Rhbmdlcm91cyJ9.6YP6T0BaO67XP--9UzTrmurXSmg
+
+data = auth_s.loads(token)
+print(data["name"])
+# itsdangerous
+```

+# Jinja
+
+Jinja is a fast, expressive, extensible templating engine. Special
+placeholders in the template allow writing code similar to Python
+syntax. Then the template is passed data to render the final document.
+
+It includes:
+
+-   Template inheritance and inclusion.
+-   Define and import macros within templates.
+-   HTML templates can use autoescaping to prevent XSS from untrusted
+    user input.
+-   A sandboxed environment can safely render untrusted templates.
+-   AsyncIO support for generating templates and calling async
+    functions.
+-   I18N support with Babel.
+-   Templates are compiled to optimized Python code just-in-time and
+    cached, or can be compiled ahead-of-time.
+-   Exceptions point to the correct line in templates to make debugging
+    easier.
+-   Extensible filters, tests, functions, and even syntax.
+
+Jinja's philosophy is that while application logic belongs in Python if
+possible, it shouldn't make the template designer's job difficult by
+restricting functionality too much.
+
+
+## In A Nutshell

+    (tummy's memcache or cmemcache) but will accept any class that provides
+    the minimal interface required.
+
+    Libraries compatible with this class:
+
+    -   `cachelib <https://github.com/pallets/cachelib>`_
+    -   `python-memcached <https://pypi.org/project/python-memcached/>`_
+
+    (Unfortunately the django cache interface is not compatible because it
+    does not support storing binary data, only text. You can however pass
+    the underlying cache client to the bytecode cache which is available
+    as `django.core.cache.cache._client`.)
+
+    The minimal interface for the client passed to the constructor is this:
+
+    .. class:: MinimalClientInterface
+
+        .. method:: set(key, value[, timeout])
+
+            Stores the bytecode in the cache.  `value` is a string and
+            `timeout` the timeout of the key.  If timeout is not provided
+            a default timeout or no timeout should be assumed, if it's
+            provided it's an integer with the number of seconds the cache
+            item should exist.
+
+        .. method:: get(key)
+
+            Returns the value for the cache key.  If the item does not
+            exist in the cache the return value must be `None`.
+
+    The other arguments to the constructor are the prefix for all keys that
+    is added before the actual cache key and the timeout for the bytecode in
+    the cache system.  We recommend a high (or no) timeout.
+
+    This bytecode cache does not support clearing of used items in the cache.
+    The clear method is a no-operation function.

+    Modifications on environments after the first template was loaded
+    will lead to surprising effects and undefined behavior.
+
+    Here are the possible initialization parameters:
+
+        `block_start_string`
+            The string marking the beginning of a block.  Defaults to ``'{%'``.
+
+        `block_end_string`
+            The string marking the end of a block.  Defaults to ``'%}'``.
+
+        `variable_start_string`
+            The string marking the beginning of a print statement.
+            Defaults to ``'{{'``.
+
+        `variable_end_string`
+            The string marking the end of a print statement.  Defaults to
+            ``'}}'``.
+
+        `comment_start_string`
+            The string marking the beginning of a comment.  Defaults to ``'{#'``.
+
+        `comment_end_string`
+            The string marking the end of a comment.  Defaults to ``'#}'``.
+
+        `line_statement_prefix`
+            If given and a string, this will be used as prefix for line based
+            statements.  See also :ref:`line-statements`.
+
+        `line_comment_prefix`
+            If given and a string, this will be used as prefix for line based
+            comments.  See also :ref:`line-statements`.
+
+            .. versionadded:: 2.2
+
+        `trim_blocks`
+            If this is set to ``True`` the first newline after a block is
+            removed (block, not variable tag!).  Defaults to `False`.
+
+        `lstrip_blocks`
+            If this is set to ``True`` leading spaces and tabs are stripped
+            from the start of a line to a block.  Defaults to `False`.
+
+        `newline_sequence`
+            The sequence that starts a newline.  Must be one of ``'\r'``,
+            ``'\n'`` or ``'\r\n'``.  The default is ``'\n'`` which is a
+            useful default for Linux and OS X systems as well as web
+            applications.
+
+        `keep_trailing_newline`
+            Preserve the trailing newline when rendering templates.
+            The default is ``False``, which causes a single newline,
+            if present, to be stripped from the end of the template.
+
+            .. versionadded:: 2.7
+
+        `extensions`
+            List of Jinja extensions to use.  This can either be import paths
+            as strings or extension classes.  For more information have a
+            look at :ref:`the extensions documentation <jinja-extensions>`.
+
+        `optimized`
+            should the optimizer be enabled?  Default is ``True``.
+
+        `undefined`
+            :class:`Undefined` or a subclass of it that is used to represent
+            undefined values in the template.
+
+        `finalize`
+            A callable that can be used to process the result of a variable
+            expression before it is output.  For example one can convert
+            ``None`` implicitly into an empty string here.
+
+        `autoescape`
+            If set to ``True`` the XML/HTML autoescaping feature is enabled by
+            default.  For more details about autoescaping see
+            :class:`~markupsafe.Markup`.  As of Jinja 2.4 this can also
+            be a callable that is passed the template name and has to
+            return ``True`` or ``False`` depending on autoescape should be
+            enabled by default.
+
+            .. versionchanged:: 2.4
+               `autoescape` can now be a function
+
+        `loader`
+            The template loader for this environment.
+
+        `cache_size`
+            The size of the cache.  Per default this is ``400`` which means
+            that if more than 400 templates are loaded the loader will clean
+            out the least recently used template.  If the cache size is set to
+            ``0`` templates are recompiled all the time, if the cache size is
+            ``-1`` the cache will not be cleaned.
+
+            .. versionchanged:: 2.8
+               The cache size was increased to 400 from a low 50.
+
+        `auto_reload`
+            Some loaders load templates from locations where the template
+            sources may change (ie: file system or database).  If
+            ``auto_reload`` is set to ``True`` (default) every time a template is
+            requested the loader checks if the source changed and if yes, it
+            will reload the template.  For higher performance it's possible to
+            disable that.
+
+        `bytecode_cache`
+            If set to a bytecode cache object, this object will provide a
+            cache for the internal Jinja bytecode so that templates don't
+            have to be parsed if they were not changed.
+
+            See :ref:`bytecode-cache` for more information.
+
+        `enable_async`
+            If set to true this enables async template execution which
+            allows using async functions and generators.

+
+    * ``lineno`` is the number of the line on which the string was found,
+    * ``function`` is the name of the ``gettext`` function used (if the

+         with multiple string arguments.

+    the values are sorted first so only one group is returned for each
+    unique value.
+
+    For example, a list of ``User`` objects with a ``city`` attribute
+    can be rendered in groups. In this example, ``grouper`` refers to

+
+    ``groupby`` yields namedtuples of ``(grouper, list)``, which
+    can be used instead of the tuple unpacking above. ``grouper`` is the

+    will have two values. This can be disabled by passing

+        The default parsing mode is a full tuple.  If `simplified` is `True`
+        only names and literals are parsed; ``with_namespace`` allows namespace
+        attr refs as well. The `no_condexpr` parameter is forwarded to
+        :meth:`parse_expression`.
+
+        Because tuples do not require delimiters and may end in a bogus comma
+        an extra hint is needed that marks the end of a tuple.  For example
+        for loops support tuples between `for` and `in`.  In that case the
+        `extra_end_rules` is set to ``['name:in']``.
+
+        `explicit_parentheses` is true if the parsing was triggered by an
+        expression in parentheses.  This is used to figure out if an empty
+        tuple is a valid expression or not.

+packaging
+=========
+
+.. start-intro
+
+Reusable core utilities for various Python Packaging
+`interoperability specifications <https://packaging.python.org/specifications/>`_.
+
+This library provides utilities that implement the interoperability
+specifications which have clearly one correct behaviour (eg: :pep:`440`)
+or benefit greatly from having a single shared implementation (eg: :pep:`425`).
+
+.. end-intro
+
+The ``packaging`` project includes the following: version handling, specifiers,
+markers, requirements, tags, utilities.
+
+Documentation
+-------------
+
+The `documentation`_ provides information and the API for the following:
+
+- Version Handling
+- Specifiers
+- Markers
+- Requirements
+- Tags
+- Utilities
+
+Installation
+------------
+
+Use ``pip`` to install these utilities::
+
+    pip install packaging
+
+The ``packaging`` library uses calendar-based versioning (``YY.N``).
+
+Discussion
+----------
+
+If you run into bugs, you can file them in our `issue tracker`_.
+
+You can also join ``#pypa`` on Freenode to ask questions or get involved.

+      source, and configuration files.
+
+      "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
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   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,
+      where such license applies only to those patent claims licensable
+      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.
+
+   END OF TERMS AND CONDITIONS

+		  GNU LESSER GENERAL PUBLIC LICENSE
+		       Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+     51 Franklin Street, Suite 500, Boston, MA  02110-1335  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL.  It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it.  You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+  When we speak of free software, we are referring to freedom of use,
+not price.  Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+  To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights.  These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  To protect each distributor, we want to make it very clear that
+there is no warranty for the free library.  Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+  Finally, software patents pose a constant threat to the existence of
+any free program.  We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder.  Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+  Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License.  This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License.  We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+  When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom.  The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+  We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License.  It also provides other free software developers Less
+of an advantage over competing non-free programs.  These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries.  However, the Lesser license provides advantages in certain
+special circumstances.
+
+  For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard.  To achieve this, non-free programs must be
+allowed to use the library.  A more frequent case is that a free
+library does the same job as widely used non-free libraries.  In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+  In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software.  For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+  Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+		  GNU LESSER GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+  
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+  6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Use a suitable shared library mechanism for linking with the
+    Library.  A suitable mechanism is one that (1) uses at run time a
+    copy of the library already present on the user's computer system,
+    rather than copying library functions into the executable, and (2)
+    will operate properly with a modified version of the library, if
+    the user installs one, as long as the modified version is
+    interface-compatible with the version that the work was made with.
+
+    c) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    d) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    e) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+			    NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+           How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.  It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the library's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This library is free software; you can redistribute it and/or
+    modify it under the terms of the GNU Lesser General Public
+    License as published by the Free Software Foundation; either
+    version 2.1 of the License, or (at your option) any later version.
+
+    This library is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
+    Lesser General Public License for more details.
+
+    You should have received a copy of the GNU Lesser General Public
+    License along with this library; if not, write to the Free Software
+    Foundation, Inc., 51 Franklin Street, Suite 500, Boston, MA  02110-1335  USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the
+  library `Frob' (a library for tweaking knobs) written by James Random Hacker.

+Welcome to Paramiko!
+====================
+
+Paramiko is a pure-Python [#]_ (3.6+) implementation of the SSHv2 protocol
+[#]_, providing both client and server functionality. It provides the
+foundation for the high-level SSH library `Fabric <https://fabfile.org>`_,
+which is what we recommend you use for common client use-cases such as running
+remote shell commands or transferring files.
+
+Direct use of Paramiko itself is only intended for users who need
+advanced/low-level primitives or want to run an in-Python sshd.
+
+For installation information, changelogs, FAQs and similar, please visit `our
+main project website <https://paramiko.org>`_; for API details, see `the
+versioned docs <https://docs.paramiko.org>`_. Additionally, the project
+maintainer keeps a `roadmap <http://bitprophet.org/projects#roadmap>`_ on his
+personal site.
+
+.. [#]
+    Paramiko relies on `cryptography <https://cryptography.io>`_ for crypto
+    functionality, which makes use of C and Rust extensions but has many
+    precompiled options available. See `our installation page
+    <https://www.paramiko.org/installing.html>`_ for details.
+
+.. [#]
+    OpenSSH's RFC specification page is a fantastic resource and collection of
+    links that we won't bother replicating here:
+    https://www.openssh.com/specs.html
+
+    OpenSSH itself also happens to be our primary reference implementation:
+    when in doubt, we consult how they do things, unless there are good reasons
+    not to. There are always some gaps, but we do our best to reconcile them
+    when possible.

+        Connect to an SSH server and authenticate to it.  The server's host key
+        is checked against the system host keys (see `load_system_host_keys`)
+        and any local host keys (`load_host_keys`).  If the server's hostname
+        is not found in either set of host keys, the missing host key policy
+        is used (see `set_missing_host_key_policy`).  The default policy is
+        to reject the key and raise an `.SSHException`.
+
+        Authentication is attempted in the following order of priority:
+
+            - The ``pkey`` or ``key_filename`` passed in (if any)
+
+              - ``key_filename`` may contain OpenSSH public certificate paths
+                as well as regular private-key paths; when files ending in
+                ``-cert.pub`` are found, they are assumed to match a private
+                key, and both components will be loaded. (The private key
+                itself does *not* need to be listed in ``key_filename`` for
+                this to occur - *just* the certificate.)
+
+            - Any key we can find through an SSH agent
+            - Any "id_rsa", "id_dsa" or "id_ecdsa" key discoverable in
+              ``~/.ssh/``
+
+              - When OpenSSH-style public certificates exist that match an
+                existing such private key (so e.g. one has ``id_rsa`` and
+                ``id_rsa-cert.pub``) the certificate will be loaded alongside
+                the private key and used for authentication.
+
+            - Plain username/password auth, if a password was given
+
+        If a private key requires a password to unlock it, and a password is
+        passed in, that password will be used to attempt to unlock the key.

+        called in server mode when the client requests a channel, after
+        authentication is complete.
+
+        If you allow channel requests (and an ssh server that didn't would be
+        useless), you should also override some of the channel request methods
+        below, which are used to determine which services will be allowed on
+        a given channel:
+
+            - `check_channel_pty_request`

+            - `check_channel_x11_request`
+            - `check_channel_forward_agent_request`
+
+        The ``chanid`` parameter is a small number that uniquely identifies the

+        unless this method returns ``OPEN_SUCCEEDED`` -- once a
+        `.Channel` object is created, you can call `.Channel.get_id` to
+        retrieve the channel ID.

+        ``0``) to allow the channel request, or one of the following error
+        codes to reject it:

+        the SSH session yet.  Use `connect` or `start_client` to begin a client
+        session, or `start_server` to begin a server session.
+
+        If the object is not actually a socket, it must have the following
+        methods:
+
+        - ``send(bytes)``: Writes from 1 to ``len(bytes)`` bytes, and returns
+          an int representing the number of bytes written.  Returns
+          0 or raises ``EOFError`` if the stream has been closed.
+        - ``recv(int)``: Reads from 1 to ``int`` bytes and returns them as a
+          string.  Returns 0 or raises ``EOFError`` if the stream has been
+          closed.
+        - ``close()``: Closes the socket.
+        - ``settimeout(n)``: Sets a (float) timeout on I/O operations.
+
+        For ease of use, you may also pass in an address (as a tuple) or a host
+        string as the ``sock`` argument.  (A host string is a hostname with an
+        optional port (separated by ``":"``) which will be converted into a
+        tuple of ``(hostname, port)``.)  A socket will be connected to this
+        address and used for communication.  Exceptions from the ``socket``
+        call may be thrown in this case.

+            iterable of algorithm identifiers, which will be disabled for the
+            lifetime of the transport.
+
+            Keys should match the last word in the class' builtin algorithm
+            tuple attributes, such as ``"ciphers"`` to disable names within
+            ``_preferred_ciphers``; or ``"kex"`` to disable something defined
+            inside ``_preferred_kex``. Values should exactly match members of
+            the matching attribute.
+
+            For example, if you need to disable
+            ``diffie-hellman-group16-sha512`` key exchange (perhaps because
+            your code talks to a server which implements it differently from

+
+pip is the `package installer`_ for Python. You can use pip to install packages from the `Python Package Index`_ and other indexes.
+
+Please take a look at our documentation for how to install and use pip:
+
+* `Installation`_
+* `Usage`_
+
+We release updates regularly, with a new version every 3 months. Find more details in our documentation:
+
+* `Release notes`_
+* `Release process`_
+
+In pip 20.3, we've `made a big improvement to the heart of pip`_; `learn more`_. We want your input, so `sign up for our user experience research studies`_ to help us do it right.
+
+**Note**: pip 21.0, in January 2021, removed Python 2 support, per pip's `Python 2 support policy`_. Please migrate to Python 3.
+
+If you find bugs, need help, or want to talk to the developers, please use our mailing lists or chat rooms:
+
+* `Issue tracking`_
+* `Discourse channel`_
+* `User IRC`_
+
+If you want to get involved head over to GitHub to get the source code, look at our development documentation and feel free to jump on the developer mailing lists and chat rooms:
+
+* `GitHub page`_
+* `Development documentation`_
+* `Development mailing list`_
+* `Development IRC`_
+

+between parses. pip parses general options twice internally, and shouldn't

+    (e.g. "a=1&b=2" vs "b=2&a=1") and produce conflicts unexpecting to users.

+    2. Parse the query to avoid the ordering issue. Note that ordering under the
+       same key in the query are NOT cleaned; i.e. "a=1&a=2" and "a=2&a=1" are
+       still considered different.

+       that this drops the "egg=" part historically used to denote the requested

+    # 2.7, pip3.3 on Python 3.3, etc. But these entry points are baked into

+    # a *different* version of Python the entry points will be wrong. The
+    # correct fix for this is to enhance the metadata to be able to describe
+    # such versioned entry points, but that won't happen till Metadata 2.0 is
+    # available.
+    # In the meantime, projects using versioned entry points will either have

+    directly, but indicate that we need additional dependencies. We model that
+    by having an artificial ExtrasCandidate that wraps the "base" candidate.
+
+    The ExtrasCandidate differs from the base in the following ways:
+
+    1. It has a unique name, of the form foo[extra]. This causes the resolver
+       to treat it as a separate node in the dependency graph.
+    2. When we're getting the candidate's dependencies,
+       a) We specify that we want the extra dependencies as well.
+       b) We add a dependency on the base candidate.
+          See below for why this is needed.
+    3. We return None for the underlying InstallRequirement, as the base
+       candidate will provide it, and we don't want to end up with duplicates.
+
+    The dependency on the base candidate is needed so that the resolver can't
+    decide that it should recommend foo[extra1] version 1.0 and foo[extra2]
+    version 2.0. Having those candidates depend on foo=1.0 and foo=2.0

+
+# This prober doesn't actually recognize a language or a charset.
+# It is a helper prober for the use of the Hebrew model probers
+
+### General ideas of the Hebrew charset recognition ###
+#
+# Four main charsets exist in Hebrew:
+# "ISO-8859-8" - Visual Hebrew
+# "windows-1255" - Logical Hebrew
+# "ISO-8859-8-I" - Logical Hebrew
+# "x-mac-hebrew" - ?? Logical Hebrew ??
+#
+# Both "ISO" charsets use a completely identical set of code points, whereas
+# "windows-1255" and "x-mac-hebrew" are two different proper supersets of
+# these code points. windows-1255 defines additional characters in the range
+# 0x80-0x9F as some misc punctuation marks as well as some Hebrew-specific
+# diacritics and additional 'Yiddish' ligature letters in the range 0xc0-0xd6.
+# x-mac-hebrew defines similar additional code points but with a different
+# mapping.
+#
+# As far as an average Hebrew text with no diacritics is concerned, all four
+# charsets are identical with respect to code points. Meaning that for the
+# main Hebrew alphabet, all four map the same values to all 27 Hebrew letters
+# (including final letters).
+#
+# The dominant difference between these charsets is their directionality.
+# "Visual" directionality means that the text is ordered as if the renderer is
+# not aware of a BIDI rendering algorithm. The renderer sees the text and
+# draws it from left to right. The text itself when ordered naturally is read
+# backwards. A buffer of Visual Hebrew generally looks like so:
+# "[last word of first line spelled backwards] [whole line ordered backwards
+# and spelled backwards] [first word of first line spelled backwards]
+# [end of line] [last word of second line] ... etc' "
+# adding punctuation marks, numbers and English text to visual text is
+# naturally also "visual" and from left to right.
+#
+# "Logical" directionality means the text is ordered "naturally" according to
+# the order it is read. It is the responsibility of the renderer to display
+# the text from right to left. A BIDI algorithm is used to place general
+# punctuation marks, numbers and English text in the text.
+#
+# Texts in x-mac-hebrew are almost impossible to find on the Internet. From
+# what little evidence I could find, it seems that its general directionality
+# is Logical.
+#
+# To sum up all of the above, the Hebrew probing mechanism knows about two
+# charsets:
+# Visual Hebrew - "ISO-8859-8" - backwards text - Words and sentences are
+#    backwards while line order is natural. For charset recognition purposes
+#    the line order is unimportant (In fact, for this implementation, even
+#    word order is unimportant).
+# Logical Hebrew - "windows-1255" - normal, naturally ordered text.
+#
+# "ISO-8859-8-I" is a subset of windows-1255 and doesn't need to be
+#    specifically identified.
+# "x-mac-hebrew" is also identified as windows-1255. A text in x-mac-hebrew
+#    that contain special punctuation marks or diacritics is displayed with
+#    some unconverted characters showing as question marks. This problem might
+#    be corrected using another model prober for x-mac-hebrew. Due to the fact
+#    that x-mac-hebrew texts are so rare, writing another model prober isn't
+#    worth the effort and performance hit.
+#
+#### The Prober ####
+#
+# The prober is divided between two SBCharSetProbers and a HebrewProber,
+# all of which are managed, created, fed data, inquired and deleted by the
+# SBCSGroupProber. The two SBCharSetProbers identify that the text is in
+# fact some kind of Hebrew, Logical or Visual. The final decision about which
+# one is it is made by the HebrewProber by combining final-letter scores
+# with the scores of the two SBCharSetProbers to produce a final answer.
+#
+# The SBCSGroupProber is responsible for stripping the original text of HTML
+# tags, English characters, numbers, low-ASCII punctuation characters, spaces
+# and new lines. It reduces any sequence of such characters to a single space.
+# The buffer fed to each prober in the SBCS group prober is pure text in
+# high-ASCII.
+# The two SBCharSetProbers (model probers) share the same language model:
+# Win1255Model.
+# The first SBCharSetProber uses the model normally as any other
+# SBCharSetProber does, to recognize windows-1255, upon which this model was
+# built. The second SBCharSetProber is told to make the pair-of-letter
+# lookup in the language model backwards. This in practice exactly simulates
+# a visual Hebrew model using the windows-1255 logical Hebrew model.
+#
+# The HebrewProber is not using any language model. All it does is look for
+# final-letter evidence suggesting the text is either logical Hebrew or visual
+# Hebrew. Disjointed from the model probers, the results of the HebrewProber
+# alone are meaningless. HebrewProber always returns 0.00 as confidence
+# since it never identifies a charset by itself. Instead, the pointer to the
+# HebrewProber is passed to the model probers as a helper "Name Prober".
+# When the Group prober receives a positive identification from any prober,
+# it asks for the name of the charset identified. If the prober queried is a
+# Hebrew model prober, the model prober forwards the call to the
+# HebrewProber to make the final decision. In the HebrewProber, the
+# decision is made according to the final-letters scores maintained and Both
+# model probers scores. The answer is returned in the form of the name of the
+# charset identified, either "windows-1255" or "ISO-8859-8".

+The ``distro`` package (``distro`` stands for Linux Distribution) provides
+information about the Linux distribution it runs on, such as a reliable
+machine-readable distro ID, or version information.
+
+It is the recommended replacement for Python's original
+:py:func:`platform.linux_distribution` function, but it provides much more
+functionality. An alternative implementation became necessary because Python
+3.5 deprecated this function, and Python 3.8 removed it altogether. Its
+predecessor function :py:func:`platform.dist` was already deprecated since
+Python 2.6 and removed in Python 3.8. Still, there are many cases in which
+access to OS distribution information is needed. See `Python issue 1322
+<https://bugs.python.org/issue1322>`_ for more information.

+    distro ID for one of the listed distros, please create an issue in the
+    `distro issue tracker`_.

+
+    * blanks (which should not be there anyway) are translated to underscores,
+
+    * a normalization of the ID is performed, based upon
+      `normalization tables`_. The purpose of this normalization is to ensure
+      that the ID is as reliable as possible, even across incompatible changes
+      in the OS distributions. A common reason for an incompatible change is
+      the addition of an os-release file, or the addition of the lsb_release

+      from the distro release file name.

+
+        Parameters:
+
+        * ``include_lsb`` (bool): Controls whether the

+          `os-release file`_ that is to be used as a data source.
+
+          An empty string (the default) will cause the default path name to

+
+          If the specified or defaulted os-release file does not exist, the
+          data source for the os-release file will be empty.
+
+        * ``distro_release_file`` (string): The path name of the
+          `distro release file`_ that is to be used as a data source.
+
+          An empty string (the default) will cause a default search algorithm
+          to be used (see `distro release file`_ for details).
+
+          If the specified distro release file does not exist, or if no default
+          distro release file can be found, the data source for the distro
+          release file will be empty.
+
+        * ``include_uname`` (bool): Controls whether uname command output is
+          included as a data source. If the uname command is not available in
+          the program execution path the data source for the uname command will
+          be empty.
+
+        * ``root_dir`` (string): The absolute path to the root directory to use
+          to find distro-related information files.
+
+        Public instance attributes:
+
+        * ``os_release_file`` (string): The path name of the
+          `os-release file`_ that is actually used as a data source. The
+          empty string if no distro release file is used as a data source.
+
+        * ``distro_release_file`` (string): The path name of the
+          `distro release file`_ that is actually used as a data source. The
+          empty string if no distro release file is used as a data source.
+
+        * ``include_lsb`` (bool): The result of the ``include_lsb`` parameter.
+          This controls whether the lsb information will be loaded.
+
+        * ``include_uname`` (bool): The result of the ``include_uname``
+          parameter. This controls whether the uname information will
+          be loaded.
+
+        Raises:
+

+"""A collection of modules for building different kinds of trees from HTML
+documents.
+
+To create a treebuilder for a new type of tree, you need to do
+implement several things:
+
+1. A set of classes for various types of elements: Document, Doctype, Comment,
+   Element. These must implement the interface of ``base.treebuilders.Node``
+   (although comment nodes have a different signature for their constructor,
+   see ``treebuilders.etree.Comment``) Textual content may also be implemented
+   as another node type, or not, as your tree implementation requires.
+
+2. A treebuilder object (called ``TreeBuilder`` by convention) that inherits
+   from ``treebuilders.base.TreeBuilder``. This has 4 required attributes:
+
+   * ``documentClass`` - the class to use for the bottommost node of a document
+   * ``elementClass`` - the class to use for HTML Elements
+   * ``commentClass`` - the class to use for comments
+   * ``doctypeClass`` - the class to use for doctypes
+
+   It also has one required method:
+
+   * ``getDocument`` - Returns the root node of the complete document tree
+
+3. If you wish to run the unit tests, you must also create a ``testSerializer``
+   method on your treebuilder which accepts a node and returns a string
+   containing Node and its children serialized according to the format used in
+   the unittests

+"""Module for supporting the lxml.etree library. The idea here is to use as much
+of the native library as possible, without using fragile hacks like custom element
+names that break between releases. The downside of this is that we cannot represent
+all possible trees; specifically the following are known to cause problems:
+
+Text or comments as siblings of the root element
+Docypes with no name
+
+When any of these things occur, we emit a DataLossWarning

+
+    :param callable default:
+        Convert user type to builtin type that Packer supports.
+        See also simplejson's document.
+
+    :param bool use_single_float:
+        Use single precision float type for float. (default: False)
+
+    :param bool autoreset:
+        Reset buffer after each pack and return its content as `bytes`. (default: True).
+        If set this to false, use `bytes()` to get content and `.reset()` to clear buffer.
+
+    :param bool use_bin_type:
+        Use bin type introduced in msgpack spec 2.0 for bytes.
+        It also enables str8 type for unicode. (default: True)
+
+    :param bool strict_types:
+        If set to true, types will be checked to be exact. Derived classes
+        from serializable types will not be serialized and will be
+        treated as unsupported type and forwarded to default.
+        Additionally tuples will not be serialized as lists.
+        This is useful when trying to implement accurate serialization
+        for python types.
+
+    :param bool datetime:
+        If set to true, datetime with tzinfo is packed into Timestamp type.
+        Note that the tzinfo is stripped in the timestamp.
+        You can get UTC datetime with `timestamp=3` option of the Unpacker.
+        (Python 2 is not supported).
+
+    :param str unicode_errors:
+        The error handler for encoding unicode. (default: 'strict')
+        DO NOT USE THIS!!  This option is kept for very specific usage.

+Package resource API
+--------------------
+
+A resource is a logical file contained within a package, or a logical
+subdirectory thereof.  The package resource API expects resource names
+to have their path parts separated with ``/``, *not* whatever the local
+path separator is.  Do not use os.path operations to manipulate resource
+names being passed into the API.
+
+The package resource API is designed to work with normal filesystem packages,
+.egg files, and unpacked .egg files.  It can also work in a limited way with
+.zip files and with custom PEP 302 loaders that support the ``get_data()``
+method.

+    Pygments
+    ~~~~~~~~
+
+    Pygments is a syntax highlighting package written in Python.
+
+    It is a generic syntax highlighter for general use in all kinds of software
+    such as forum systems, wikis or other applications that need to prettify
+    source code. Highlights are:
+
+    * a wide range of common languages and markup formats is supported
+    * special attention is paid to details, increasing quality by a fair amount
+    * support for new languages and formats are added easily
+    * a number of output formats, presently HTML, LaTeX, RTF, SVG, all image
+      formats that PIL supports, and ANSI sequences
+    * it is usable as a command-line tool and as a library
+    * ... and it highlights even Brainfuck!
+
+    The `Pygments master branch`_ is installable with ``easy_install Pygments==dev``.

+class HtmlFormatter(Formatter):
+    r"""
+    Format tokens as HTML 4 ``<span>`` tags within a ``<pre>`` tag, wrapped
+    in a ``<div>`` tag. The ``<div>``'s CSS class can be set by the `cssclass`
+    option.
+
+    If the `linenos` option is set to ``"table"``, the ``<pre>`` is
+    additionally wrapped inside a ``<table>`` which has one row and two
+    cells: one containing the line numbers and one containing the code.
+    Example:
+
+    .. sourcecode:: html
+
+        <div class="highlight" >
+        <table><tr>
+          <td class="linenos" title="click to toggle"
+            onclick="with (this.firstChild.style)
+                     { display = (display == '') ? 'none' : '' }">
+            <pre>1
+            2</pre>
+          </td>
+          <td class="code">
+            <pre><span class="Ke">def </span><span class="NaFu">foo</span>(bar):
+              <span class="Ke">pass</span>
+            </pre>
+          </td>
+        </tr></table></div>
+
+    (whitespace added to improve clarity).
+
+    Wrapping can be disabled using the `nowrap` option.
+
+    A list of lines can be specified using the `hl_lines` option to make these
+    lines highlighted (as of Pygments 0.11).
+
+    With the `full` option, a complete HTML 4 document is output, including
+    the style definitions inside a ``<style>`` tag, or in a separate file if
+    the `cssfile` option is given.
+
+    When `tagsfile` is set to the path of a ctags index file, it is used to
+    generate hyperlinks from names to their definition.  You must enable
+    `lineanchors` and run ctags with the `-n` option for this to work.  The
+    `python-ctags` module from PyPI must be installed to use this feature;
+    otherwise a `RuntimeError` will be raised.
+
+    The `get_style_defs(arg='')` method of a `HtmlFormatter` returns a string
+    containing CSS rules for the CSS classes used by the formatter. The
+    argument `arg` can be used to specify additional CSS selectors that
+    are prepended to the classes. A call `fmter.get_style_defs('td .code')`
+    would result in the following CSS classes:
+
+    .. sourcecode:: css
+
+        td .code .kw { font-weight: bold; color: #00FF00 }
+        td .code .cm { color: #999999 }
+        ...
+
+    If you have Pygments 0.6 or higher, you can also pass a list or tuple to the
+    `get_style_defs()` method to request multiple prefixes for the tokens:
+
+    .. sourcecode:: python
+
+        formatter.get_style_defs(['div.syntax pre', 'pre.syntax'])
+
+    The output would then look like this:
+
+    .. sourcecode:: css
+
+        div.syntax pre .kw,
+        pre.syntax .kw { font-weight: bold; color: #00FF00 }
+        div.syntax pre .cm,
+        pre.syntax .cm { color: #999999 }
+        ...
+
+    Additional options accepted:
+
+    `nowrap`
+        If set to ``True``, don't wrap the tokens at all, not even inside a ``<pre>``
+        tag. This disables most other options (default: ``False``).
+
+    `full`
+        Tells the formatter to output a "full" document, i.e. a complete
+        self-contained document (default: ``False``).
+
+    `title`
+        If `full` is true, the title that should be used to caption the
+        document (default: ``''``).
+
+    `style`
+        The style to use, can be a string or a Style subclass (default:
+        ``'default'``). This option has no effect if the `cssfile`
+        and `noclobber_cssfile` option are given and the file specified in
+        `cssfile` exists.
+
+    `noclasses`
+        If set to true, token ``<span>`` tags (as well as line number elements)
+        will not use CSS classes, but inline styles. This is not recommended
+        for larger pieces of code since it increases output size by quite a bit
+        (default: ``False``).
+
+    `classprefix`
+        Since the token types use relatively short class names, they may clash
+        with some of your own class names. In this case you can use the
+        `classprefix` option to give a string to prepend to all Pygments-generated
+        CSS class names for token types.
+        Note that this option also affects the output of `get_style_defs()`.
+
+    `cssclass`
+        CSS class for the wrapping ``<div>`` tag (default: ``'highlight'``).
+        If you set this option, the default selector for `get_style_defs()`
+        will be this class.
+
+        .. versionadded:: 0.9
+           If you select the ``'table'`` line numbers, the wrapping table will
+           have a CSS class of this string plus ``'table'``, the default is
+           accordingly ``'highlighttable'``.
+
+    `cssstyles`
+        Inline CSS styles for the wrapping ``<div>`` tag (default: ``''``).
+
+    `prestyles`
+        Inline CSS styles for the ``<pre>`` tag (default: ``''``).
+
+        .. versionadded:: 0.11
+
+    `cssfile`
+        If the `full` option is true and this option is given, it must be the
+        name of an external file. If the filename does not include an absolute
+        path, the file's path will be assumed to be relative to the main output
+        file's path, if the latter can be found. The stylesheet is then written
+        to this file instead of the HTML file.
+
+        .. versionadded:: 0.6
+
+    `noclobber_cssfile`
+        If `cssfile` is given and the specified file exists, the css file will
+        not be overwritten. This allows the use of the `full` option in
+        combination with a user specified css file. Default is ``False``.
+
+        .. versionadded:: 1.1
+
+    `linenos`
+        If set to ``'table'``, output line numbers as a table with two cells,
+        one containing the line numbers, the other the whole code.  This is
+        copy-and-paste-friendly, but may cause alignment problems with some
+        browsers or fonts.  If set to ``'inline'``, the line numbers will be
+        integrated in the ``<pre>`` tag that contains the code (that setting
+        is *new in Pygments 0.8*).
+
+        For compatibility with Pygments 0.7 and earlier, every true value
+        except ``'inline'`` means the same as ``'table'`` (in particular, that
+        means also ``True``).
+
+        The default value is ``False``, which means no line numbers at all.
+
+        **Note:** with the default ("table") line number mechanism, the line
+        numbers and code can have different line heights in Internet Explorer
+        unless you give the enclosing ``<pre>`` tags an explicit ``line-height``
+        CSS property (you get the default line spacing with ``line-height:
+        125%``).
+
+    `hl_lines`
+        Specify a list of lines to be highlighted. The line numbers are always
+        relative to the input (i.e. the first line is line 1) and are
+        independent of `linenostart`.
+
+        .. versionadded:: 0.11
+
+    `linenostart`
+        The line number for the first line (default: ``1``).
+
+    `linenostep`
+        If set to a number n > 1, only every nth line number is printed.
+
+    `linenospecial`
+        If set to a number n > 0, every nth line number is given the CSS
+        class ``"special"`` (default: ``0``).
+
+    `nobackground`
+        If set to ``True``, the formatter won't output the background color
+        for the wrapping element (this automatically defaults to ``False``
+        when there is no wrapping element [eg: no argument for the
+        `get_syntax_defs` method given]) (default: ``False``).
+
+        .. versionadded:: 0.6
+
+    `lineseparator`
+        This string is output between lines of code. It defaults to ``"\n"``,
+        which is enough to break a line inside ``<pre>`` tags, but you can
+        e.g. set it to ``"<br>"`` to get HTML line breaks.
+
+        .. versionadded:: 0.7
+
+    `lineanchors`
+        If set to a nonempty string, e.g. ``foo``, the formatter will wrap each
+        output line in an anchor tag with an ``id`` (and `name`) of ``foo-linenumber``.
+        This allows easy linking to certain lines.
+
+        .. versionadded:: 0.9
+
+    `linespans`
+        If set to a nonempty string, e.g. ``foo``, the formatter will wrap each
+        output line in a span tag with an ``id`` of ``foo-linenumber``.
+        This allows easy access to lines via javascript.
+
+        .. versionadded:: 1.6
+
+    `anchorlinenos`
+        If set to `True`, will wrap line numbers in <a> tags. Used in
+        combination with `linenos` and `lineanchors`.
+
+    `tagsfile`
+        If set to the path of a ctags file, wrap names in anchor tags that
+        link to their definitions. `lineanchors` should be used, and the
+        tags file should specify line numbers (see the `-n` option to ctags).
+
+        .. versionadded:: 1.6
+
+    `tagurlformat`
+        A string formatting pattern used to generate links to ctags definitions.
+        Available variables are `%(path)s`, `%(fname)s` and `%(fext)s`.
+        Defaults to an empty string, resulting in just `#prefix-number` links.
+
+        .. versionadded:: 1.6
+
+    `filename`
+        A string used to generate a filename when rendering ``<pre>`` blocks,
+        for example if displaying source code. If `linenos` is set to
+        ``'table'`` then the filename will be rendered in an initial row
+        containing a single `<th>` which spans both columns.
+
+        .. versionadded:: 2.1
+
+    `wrapcode`
+        Wrap the code inside ``<pre>`` blocks using ``<code>``, as recommended
+        by the HTML5 specification.
+
+        .. versionadded:: 2.4
+
+    `debug_token_types`
+        Add ``title`` attributes to all token ``<span>`` tags that show the
+        name of the token.
+
+        .. versionadded:: 2.10
+
+
+    **Subclassing the HTML formatter**
+
+    .. versionadded:: 0.7
+
+    The HTML formatter is now built in a way that allows easy subclassing, thus
+    customizing the output HTML code. The `format()` method calls
+    `self._format_lines()` which returns a generator that yields tuples of ``(1,
+    line)``, where the ``1`` indicates that the ``line`` is a line of the
+    formatted source code.
+
+    If the `nowrap` option is set, the generator is the iterated over and the
+    resulting HTML is output.
+
+    Otherwise, `format()` calls `self.wrap()`, which wraps the generator with
+    other generators. These may add some HTML code to the one generated by
+    `_format_lines()`, either by modifying the lines generated by the latter,
+    then yielding them again with ``(1, line)``, and/or by yielding other HTML
+    code before or after the lines, with ``(0, html)``. The distinction between
+    source lines and other code makes it possible to wrap the generator multiple
+    times.
+
+    The default `wrap()` implementation adds a ``<div>`` and a ``<pre>`` tag.
+
+    A custom `HtmlFormatter` subclass could look like this:
+
+    .. sourcecode:: python
+
+        class CodeHtmlFormatter(HtmlFormatter):
+
+            def wrap(self, source, outfile):
+                return self._wrap_code(source)
+
+            def _wrap_code(self, source):
+                yield 0, '<code>'
+                for i, t in source:
+                    if i == 1:
+                        # it's a line of formatted code
+                        t += '<br>'
+                    yield i, t
+                yield 0, '</code>'
+
+    This results in wrapping the formatted lines with a ``<code>`` tag, where the
+    source lines are broken using ``<br>`` tags.
+
+    After calling `wrap()`, the `format()` method also adds the "line numbers"
+    and/or "full document" wrappers if the respective options are set. Then, all
+    HTML yielded by the wrapped generator is output.

+## Small explanation of the mess below :)
+#
+# The previous version of the LaTeX formatter just assigned a command to
+# each token type defined in the current style.  That obviously is
+# problematic if the highlighted code is produced for a different style
+# than the style commands themselves.
+#
+# This version works much like the HTML formatter which assigns multiple
+# CSS classes to each <span> tag, from the most specific to the least
+# specific token type, thus falling back to the parent token type if one
+# is not defined.  Here, the classes are there too and use the same short
+# forms given in token.STANDARD_TYPES.
+#
+# Highlighted code now only uses one custom command, which by default is
+# \PY and selectable by the commandprefix option (and in addition the
+# escapes \PYZat, \PYZlb and \PYZrb which haven't been renamed for
+# backwards compatibility purposes).
+#
+# \PY has two arguments: the classes, separated by +, and the text to
+# render in that style.  The classes are resolved into the respective
+# style commands by magic, which serves to ignore unknown classes.
+#
+# The magic macros are:
+# * \PY@it, \PY@bf, etc. are unconditionally wrapped around the text
+#   to render in \PY@do.  Their definition determines the style.
+# * \PY@reset resets \PY@it etc. to do nothing.
+# * \PY@toks parses the list of classes, using magic inspired by the
+#   keyval package (but modified to use plusses instead of commas
+#   because fancyvrb redefines commas inside its environments).
+# * \PY@tok processes one class, calling the \PY@tok@classname command
+#   if it exists.
+# * \PY@tok@classname sets the \PY@it etc. to reflect the chosen style
+#   for its class.
+# * \PY resets the style, parses the classnames and then calls \PY@do.
+#
+# Tip: to read this code, print it out in substituted form using e.g.
+# >>> print STYLE_TEMPLATE % {'cp': 'PY'}

+    r"""
+    Format tokens as LaTeX code. This needs the `fancyvrb` and `color`
+    standard packages.
+
+    Without the `full` option, code is formatted as one ``Verbatim``
+    environment, like this:
+
+    .. sourcecode:: latex
+
+        \begin{Verbatim}[commandchars=\\\{\}]
+        \PY{k}{def }\PY{n+nf}{foo}(\PY{n}{bar}):
+            \PY{k}{pass}
+        \end{Verbatim}
+
+    The special command used here (``\PY``) and all the other macros it needs
+    are output by the `get_style_defs` method.
+
+    With the `full` option, a complete LaTeX document is output, including
+    the command definitions in the preamble.
+
+    The `get_style_defs()` method of a `LatexFormatter` returns a string
+    containing ``\def`` commands defining the macros needed inside the
+    ``Verbatim`` environments.
+
+    Additional options accepted:
+
+    `style`
+        The style to use, can be a string or a Style subclass (default:
+        ``'default'``).
+
+    `full`
+        Tells the formatter to output a "full" document, i.e. a complete
+        self-contained document (default: ``False``).
+
+    `title`
+        If `full` is true, the title that should be used to caption the
+        document (default: ``''``).
+
+    `docclass`
+        If the `full` option is enabled, this is the document class to use
+        (default: ``'article'``).
+
+    `preamble`
+        If the `full` option is enabled, this can be further preamble commands,
+        e.g. ``\usepackage`` (default: ``''``).
+
+    `linenos`
+        If set to ``True``, output line numbers (default: ``False``).
+
+    `linenostart`
+        The line number for the first line (default: ``1``).
+
+    `linenostep`
+        If set to a number n > 1, only every nth line number is printed.
+
+    `verboptions`
+        Additional options given to the Verbatim environment (see the *fancyvrb*
+        docs for possible values) (default: ``''``).
+
+    `commandprefix`
+        The LaTeX commands used to produce colored output are constructed
+        using this prefix and some letters (default: ``'PY'``).
+
+        .. versionadded:: 0.7
+        .. versionchanged:: 0.10
+           The default is now ``'PY'`` instead of ``'C'``.
+
+    `texcomments`
+        If set to ``True``, enables LaTeX comment lines.  That is, LaTex markup
+        in comment tokens is not escaped so that LaTeX can render it (default:
+        ``False``).
+
+        .. versionadded:: 1.2
+
+    `mathescape`
+        If set to ``True``, enables LaTeX math mode escape in comments. That
+        is, ``'$...$'`` inside a comment will trigger math mode (default:
+        ``False``).
+
+        .. versionadded:: 1.2
+
+    `escapeinside`
+        If set to a string of length 2, enables escaping to LaTeX. Text
+        delimited by these 2 characters is read as LaTeX code and
+        typeset accordingly. It has no effect in string literals. It has
+        no effect in comments if `texcomments` or `mathescape` is
+        set. (default: ``''``).
+
+        .. versionadded:: 2.0
+
+    `envname`
+        Allows you to pick an alternative environment name replacing Verbatim.
+        The alternate environment still has to support Verbatim's option syntax.
+        (default: ``'Verbatim'``).

+        don't add a XML declaration and a doctype.  If true, the `fontfamily`
+        and `fontsize` options are ignored.  Defaults to ``False``.
+
+    `fontfamily`
+        The value to give the wrapping ``<g>`` element's ``font-family``
+        attribute, defaults to ``"monospace"``.
+
+    `fontsize`
+        The value to give the wrapping ``<g>`` element's ``font-size``
+        attribute, defaults to ``"14px"``.
+
+    `linenos`
+        If ``True``, add line numbers (default: ``False``).
+
+    `linenostart`
+        The line number for the first line (default: ``1``).
+
+    `linenostep`
+        If set to a number n > 1, only every nth line number is printed.
+        
+    `linenowidth`
+        Maximum width devoted to line numbers (default: ``3*ystep``, sufficient
+        for up to 4-digit line numbers. Increase width for longer code blocks).  
+        
+    `xoffset`
+        Starting offset in X direction, defaults to ``0``.
+
+    `yoffset`
+        Starting offset in Y direction, defaults to the font size if it is given
+        in pixels, or ``20`` else.  (This is necessary since text coordinates
+        refer to the text baseline, not the top edge.)
+
+    `ystep`
+        Offset to add to the Y coordinate for each subsequent line.  This should
+        roughly be the text size plus 5.  It defaults to that value if the text
+        size is given in pixels, or ``25`` else.
+
+    `spacehack`
+        Convert spaces in the source to ``&#160;``, which are non-breaking
+        spaces.  SVG provides the ``xml:space`` attribute to control how
+        whitespace inside tags is handled, in theory, the ``preserve`` value
+        could be used to keep all whitespace as-is.  However, many current SVG
+        viewers don't obey that rule, so this option is provided as a workaround
+        and defaults to ``True``.

+pyparsing module - Classes and methods to define and execute parsing grammars
+=============================================================================
+
+The pyparsing module is an alternative approach to creating and
+executing simple grammars, vs. the traditional lex/yacc approach, or the
+use of regular expressions.  With pyparsing, you don't need to learn
+a new syntax for defining grammars or matching expressions - the parsing
+module provides a library of classes that you use to construct the
+grammar directly in Python.
+
+Here is a program to parse "Hello, World!" (or any greeting of the form
+``"<salutation>, <addressee>!"``), built up using :class:`Word`,
+:class:`Literal`, and :class:`And` elements
+(the :meth:`'+'<ParserElement.__add__>` operators create :class:`And` expressions,
+and the strings are auto-converted to :class:`Literal` expressions)::
+
+    from pip._vendor.pyparsing import Word, alphas
+
+    # define grammar of a greeting
+    greet = Word(alphas) + "," + Word(alphas) + "!"
+
+    hello = "Hello, World!"
+    print(hello, "->", greet.parse_string(hello))
+
+The program outputs the following::
+
+    Hello, World! -> ['Hello', ',', 'World', '!']
+
+The Python representation of the grammar is quite readable, owing to the
+self-explanatory class names, and the use of :class:`'+'<And>`,
+:class:`'|'<MatchFirst>`, :class:`'^'<Or>` and :class:`'&'<Each>` operators.
+
+The :class:`ParseResults` object returned from
+:class:`ParserElement.parseString` can be
+accessed as a nested list, a dictionary, or an object with named
+attributes.
+
+The pyparsing module handles some of the problems that are typically
+vexing when writing text parsers:
+
+  - extra or missing whitespace (the above program will also handle
+    "Hello,World!", "Hello  ,  World  !", etc.)
+  - quoted strings
+  - embedded comments
+
+
+Getting Started -
+-----------------
+Visit the classes :class:`ParserElement` and :class:`ParseResults` to
+see the base classes that most other pyparsing
+classes inherit from. Use the docstrings for examples of how to:
+
+ - construct literal match expressions from :class:`Literal` and
+   :class:`CaselessLiteral` classes
+ - construct character word-group expressions using the :class:`Word`
+   class
+ - see how to create repetitive expressions using :class:`ZeroOrMore`
+   and :class:`OneOrMore` classes
+ - use :class:`'+'<And>`, :class:`'|'<MatchFirst>`, :class:`'^'<Or>`,
+   and :class:`'&'<Each>` operators to combine simple expressions into
+   more complex ones
+ - associate names with your parsed results using
+   :class:`ParserElement.setResultsName`
+ - access the parsed data, which is returned as a :class:`ParseResults`
+   object
+ - find some helpful expression short-cuts like :class:`delimitedList`
+   and :class:`oneOf`
+ - find more useful common expressions in the :class:`pyparsing_common`
+   namespace class

+
+        Parse actions can be called to perform data conversions, do extra validation,
+        update external data structures, or enhance or replace the parsed tokens.
+        Each parse action ``fn`` is a callable method with 0-3 arguments, called as
+        ``fn(s, loc, toks)`` , ``fn(loc, toks)`` , ``fn(toks)`` , or just ``fn()`` , where:
+

+        - loc = the location of the matching substring
+        - toks = a list of the matched tokens, packaged as a :class:`ParseResults` object
+
+        The parsed tokens are passed to the parse action as ParseResults. They can be
+        modified in place using list-style append, extend, and pop operations to update
+        the parsed list elements; and with dictionary-style item set and del operations
+        to add, update, or remove any named results. If the tokens are modified in place,
+        it is not necessary to return them with a return statement.
+
+        Parse actions can also completely replace the given tokens, with another ``ParseResults``
+        object, or with some entirely different object (common for parse actions that perform data
+        conversions). A convenient way to build a new parse result is to define the values
+        using a dict, and then create the return value using :class:`ParseResults.from_dict`.
+
+        If None is passed as the ``fn`` parse action, all previously added parse actions for this
+        expression are cleared.
+
+        Optional keyword arguments:
+
+        - call_during_try = (default= ``False``) indicate if parse action should be run during
+          lookaheads and alternate testing. For parse actions that have side effects, it is
+          important to only call the parse action once it is determined that it is being
+          called as part of a successful parse. For parse actions that perform additional
+          validation, then call_during_try should be passed as True, so that the validation
+          code is included in the preliminary "try" parses.
+
+        Note: the default parsing behavior is to expand tabs in the input string
+        before starting the parsing process.  See :class:`parse_string` for more
+        information on parsing strings containing ``<TAB>`` s, and suggested
+        methods to maintain a consistent view of the parsed string, the parse
+        location, and line and column positions within the parsed string.

+        Parse a string with respect to the parser definition. This function is intended as the primary interface to the
+        client code.
+
+        :param instring: The input string to be parsed.
+        :param parse_all: If set, the entire input string must match the grammar.
+        :param parseAll: retained for pre-PEP8 compatibility, will be removed in a future release.
+        :raises ParseException: Raised if ``parse_all`` is set and the input string does not match the whole grammar.
+        :returns: the parsed data as a :class:`ParseResults` object, which may be accessed as a `list`, a `dict`, or
+          an object with attributes if the given parser includes results names.
+
+        If the input string is required to match the entire grammar, ``parse_all`` flag must be set to ``True``. This
+        is also equivalent to ending the grammar with :class:`StringEnd`().
+
+        To report proper column numbers, ``parse_string`` operates on a copy of the input string where all tabs are
+        converted to spaces (8 spaces per tab, as per the default in ``string.expandtabs``). If the input string
+        contains tabs and the grammar uses parse actions that use the ``loc`` argument to index into the string
+        being parsed, one can ensure a consistent view of the input string by doing one of the following:
+
+        - calling ``parse_with_tabs`` on your grammar before calling ``parse_string`` (see :class:`parse_with_tabs`),
+        - define your parse action using the full ``(s,loc,toks)`` signature, and reference the input string using the
+          parse action's ``s`` argument, or
+        - explicitly expand the tabs in your input string before calling ``parse_string``.
+
+        Examples:
+
+        By default, partial matches are OK.
+
+        >>> res = Word('a').parse_string('aaaaabaaa')
+        >>> print(res)
+        ['aaaaa']
+
+        The parsing behavior varies by the inheriting class of this abstract class. Please refer to the children
+        directly to see more examples.
+
+        It raises an exception if parse_all flag is set and instring does not match the whole grammar.

+      if ``body_chars`` is also specified, then this is the string of
+      initial characters
+    - ``body_chars`` - string of characters that
+      can be used for matching after a matched initial character as

+      (default=``None``)
+    - ``min`` - minimum number of characters to match (default=1)
+    - ``max`` - maximum number of characters to match (default=0)
+    - ``exact`` - exact number of characters to match (default=0)
+    - ``as_keyword`` - match as a keyword (default=``False``)

+      (default=``None``)
+
+    :class:`srange` is useful for defining custom character set strings
+    for defining :class:`Word` expressions, using range notation from
+    regular expression character sets.
+
+    A common mistake is to use :class:`Word` to match a specific literal
+    string, as in ``Word("Address")``. Remember that :class:`Word`
+    uses the string argument to define *sets* of matchable characters.
+    This expression would match "Add", "AAA", "dAred", or any other word
+    made up of the characters 'A', 'd', 'r', 'e', and 's'. To match an
+    exact literal string, use :class:`Literal` or :class:`Keyword`.
+
+    pyparsing includes helper strings for building Words:
+
+    - :class:`alphas`
+    - :class:`nums`
+    - :class:`alphanums`
+    - :class:`hexnums`
+    - :class:`alphas8bit` (alphabetic characters in ASCII range 128-255
+      - accented, tilded, umlauted, etc.)
+    - :class:`punc8bit` (non-alphabetic characters in ASCII range
+      128-255 - currency, symbols, superscripts, diacriticals, etc.)
+    - :class:`printables` (any non-whitespace character)
+
+    ``alphas``, ``nums``, and ``printables`` are also defined in several
+    Unicode sets - see :class:`pyparsing_unicode``.
+
+    Example::
+
+        # a word composed of digits
+        integer = Word(nums) # equivalent to Word("0123456789") or Word(srange("0-9"))
+
+        # a word with a leading capital, and zero or more lowercase
+        capital_word = Word(alphas.upper(), alphas.lower())
+
+        # hostnames are alphanumeric, with leading alpha, and '-'
+        hostname = Word(alphas, alphanums + '-')
+
+        # roman numeral (not a strict parser, accepts invalid mix of characters)
+        roman = Word("IVXLCDM")

+    (DEPRECATED - use IndentedBlock class instead)
+    Helper method for defining space-delimited indentation blocks,
+    such as those used to define block statements in Python source code.
+
+    Parameters:
+
+    - ``blockStatementExpr`` - expression defining syntax of statement that
+      is repeated within the indented block
+    - ``indentStack`` - list created by caller to manage indentation stack
+      (multiple ``statementWithIndentedBlock`` expressions within a single
+      grammar should share a common ``indentStack``)
+    - ``indent`` - boolean indicating whether block must be indented beyond
+      the current level; set to ``False`` for block of left-most statements
+      (default= ``True``)
+
+    A valid block must contain at least one ``blockStatement``.
+
+    (Note that indentedBlock uses internal parse actions which make it
+    incompatible with packrat parsing.)

+Requests HTTP Library
+~~~~~~~~~~~~~~~~~~~~~
+
+Requests is an HTTP library, written in Python, for human beings.
+Basic GET usage:
+
+   >>> import requests
+   >>> r = requests.get('https://www.python.org')
+   >>> r.status_code
+   200
+   >>> b'Python is a programming language' in r.content
+   True
+
+... or POST:
+
+   >>> payload = dict(key1='value1', key2='value2')
+   >>> r = requests.post('https://httpbin.org/post', data=payload)
+   >>> print(r.text)
+   {
+     ...
+     "form": {
+       "key1": "value1",
+       "key2": "value2"
+     },
+     ...
+   }
+
+The other HTTP methods are supported - see `requests.api`. Full documentation
+is at <https://requests.readthedocs.io>.

+        See class Generic for more information on generic types.  An
+        example for annotating a decorator::

+           T = TypeVar('T')
+           P = ParamSpec('P')

+           `preload_content=False` the default behaviour someday soon without
+           breaking backwards compatibility.
+

+            HTTP request method (such as GET, POST, PUT, etc.)

+            Data to send in the request body, either :class:`str`, :class:`bytes`,
+            an iterable of :class:`str`/:class:`bytes`, or a file-like object.
+
+        :param headers:
+            Dictionary of custom headers to send, such as User-Agent,
+            If-None-Match, etc. If None, pool headers are used. If provided,
+            these headers completely replace any pool-specific headers.

+            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.

+            If ``True``, will make sure that the host of the pool requests is

+            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

+
+        :param chunked:
+            If True, urllib3 will send the body using chunked transfer

+        :param int body_pos:
+            Position to seek to in file-like body in the event of a retry or

+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 pip._vendor.urllib3 import PoolManager
+    from pip._vendor.urllib3.contrib.appengine import AppEngineManager, is_appengine_sandbox
+
+    if is_appengine_sandbox():

+        # 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.

+TLS with SNI_-support for Python 2. Follow these instructions if you would
+like to verify TLS certificates in Python 2. Note, the default libraries do
+*not* do certificate checking; you need to do additional work to validate
+certificates yourself.
+
+This needs the following packages installed:
+
+* `pyOpenSSL`_ (tested with 16.0.0)
+* `cryptography`_ (minimum 1.3.4, from pyopenssl)
+* `idna`_ (minimum 2.0, from cryptography)
+
+However, pyopenssl depends on cryptography, which depends on idna, so while we
+use all three directly here we end up having relatively few packages required.
+
+You can install them with the following command:
+
+.. code-block:: bash
+
+    $ python -m pip install pyopenssl cryptography idna
+
+To activate certificate checking, call
+:func:`~urllib3.contrib.pyopenssl.inject_into_urllib3` from your Python code
+before you begin making HTTP requests. This can be done in a ``sitecustomize``
+module, or at any other time before your application begins using ``urllib3``,
+like this:
+
+.. code-block:: python
+
+    try:
+        import pip._vendor.urllib3.contrib.pyopenssl as pyopenssl
+        pyopenssl.inject_into_urllib3()
+    except ImportError:
+        pass
+
+Now you can use :mod:`urllib3` as you normally would, and it will support SNI
+when the required modules are installed.
+
+Activating this module also has the positive side effect of disabling SSL/TLS
+compression in Python 2 (see `CRIME attack`_).

+SecureTranport support for urllib3 via ctypes.
+
+This makes platform-native TLS available to urllib3 users on macOS without the
+use of a compiler. This is an important feature because the Python Package
+Index is moving to become a TLSv1.2-or-higher server, and the default OpenSSL
+that ships with macOS is not capable of doing TLSv1.2. The only way to resolve
+this is to give macOS users an alternative solution to the problem, and that
+solution is to use SecureTransport.
+
+We use ctypes here because this solution must not require a compiler. That's
+because pip is not allowed to require a compiler either.
+
+This is not intended to be a seriously long-term solution to this problem.
+The hope is that PEP 543 will eventually solve this issue for us, at which
+point we can retire this contrib module. But in the short term, we need to
+solve the impending tire fire that is Python on Mac without this kind of
+contrib module. So...here we are.
+
+To use this module, simply import and inject it::
+
+    import pip._vendor.urllib3.contrib.securetransport as securetransport
+    securetransport.inject_into_urllib3()
+
+Happy TLSing!

+This module contains provisional support for SOCKS proxies from within
+urllib3. This module supports SOCKS4, SOCKS4A (an extension of SOCKS4), and
+SOCKS5. To enable its functionality, either install PySocks or install this
+module with the ``socks`` extra.
+
+The SOCKS implementation supports the full range of urllib3 features. It also
+supports the following SOCKS features:
+
+- SOCKS4A (``proxy_url='socks4a://...``)
+- SOCKS4 (``proxy_url='socks4://...``)
+- SOCKS5 with remote DNS (``proxy_url='socks5h://...``)
+- SOCKS5 with local DNS (``proxy_url='socks5://...``)
+- Usernames and passwords for the SOCKS proxy
+
+.. note::
+   It is recommended to use ``socks5h://`` or ``socks4a://`` schemes in
+   your ``proxy_url`` to ensure that DNS resolution is done from the remote
+   server instead of client-side when connecting to a domain name.
+
+SOCKS4 supports IPv4 and domain names with the SOCKS4A extension. SOCKS5
+supports IPv4, IPv6, and domain names.
+
+When connecting to a SOCKS4 proxy the ``username`` portion of the ``proxy_url``
+will be sent as the ``userid`` section of the SOCKS request:
+
+.. code-block:: python
+
+    proxy_url="socks4a://<userid>@proxy-host"
+
+When connecting to a SOCKS5 proxy the ``username`` and ``password`` portion
+of the ``proxy_url`` will be sent as the username/password to authenticate
+with the proxy:
+
+.. code-block:: python
+
+    proxy_url="socks5h://<username>:<password>@proxy-host"

+    Backwards-compatible with :class:`http.client.HTTPResponse` but the response ``body`` is
+    loaded and decoded on-demand when the ``data`` property is accessed.  This
+    class is also compatible with the Python standard library's :mod:`io`
+    module, and can hence be treated as a readable object in the context of that
+    framework.
+
+    Extra parameters for behaviour not present in :class:`http.client.HTTPResponse`:
+
+    :param preload_content:
+        If True, the response's body will be preloaded during construction.
+
+    :param decode_content:
+        If True, will attempt to decode the body based on the
+        'content-encoding' header.
+
+    :param original_response:
+        When this HTTPResponse wrapper is generated from an :class:`http.client.HTTPResponse`
+        object, it's convenient to include the original for debug purposes. It's
+        otherwise unused.
+
+    :param retries:
+        The retries contains the last :class:`~urllib3.util.retry.Retry` that
+        was used during the request.
+
+    :param enforce_content_length:
+        Enforce content length checking. Body returned by server must match
+        value of Content-Length header, if present. Otherwise, raise error.

+        Set to ``False`` to disable and imply ``raise_on_redirect=False``.
+
+    :param int status:
+        How many times to retry on bad status codes.
+
+        These are retries made on responses, where status code matches
+        ``status_forcelist``.
+
+        Set to ``0`` to fail on the first retry of this type.
+
+    :param int other:
+        How many times to retry on other errors.
+
+        Other errors are errors that are not connect, read, redirect or status errors.
+        These errors might be raised after the request was sent to the server, so the
+        request might have side-effects.
+
+        Set to ``0`` to fail on the first retry of this type.
+
+        If ``total`` is not set, it's a good idea to set this to 0 to account
+        for unexpected edge cases and avoid infinite retry loops.
+
+    :param iterable allowed_methods:
+        Set of uppercased HTTP method verbs that we should retry on.
+
+        By default, we only retry on methods which are considered to be
+        idempotent (multiple requests with the same parameters end with the
+        same state). See :attr:`Retry.DEFAULT_ALLOWED_METHODS`.
+
+        Set to a ``False`` value to retry on any verb.
+
+        .. warning::
+
+            Previously this parameter was named ``method_whitelist``, that
+            usage is deprecated in v1.26.0 and will be removed in v2.0.
+
+    :param iterable status_forcelist:
+        A set of integer HTTP status codes that we should force a retry on.
+        A retry is initiated if the request method is in ``allowed_methods``
+        and the response status code is in ``status_forcelist``.
+
+        By default, this is disabled with ``None``.
+
+    :param float backoff_factor:
+        A backoff factor to apply between attempts after the second try
+        (most errors are resolved immediately by a second try without a
+        delay). urllib3 will sleep for::
+
+            {backoff factor} * (2 ** ({number of total retries} - 1))
+
+        seconds. If the backoff_factor is 0.1, then :func:`.sleep` will sleep
+        for [0.0s, 0.2s, 0.4s, ...] between retries. It will never be longer
+        than :attr:`Retry.DEFAULT_BACKOFF_MAX`.
+
+        By default, backoff is disabled (set to 0).
+
+    :param bool raise_on_redirect: Whether, if the number of redirects is
+        exhausted, to raise a MaxRetryError, or to return a response with a
+        response code in the 3xx range.
+
+    :param bool raise_on_status: Similar meaning to ``raise_on_redirect``:
+        whether we should raise an exception, or return a response,
+        if status falls in ``status_forcelist`` range and retries have
+        been exhausted.
+
+    :param tuple history: The history of the request encountered during
+        each call to :meth:`~Retry.increment`. The list is in the order
+        the requests occurred. Each list item is of class :class:`RequestHistory`.
+
+    :param bool respect_retry_after_header:
+        Whether to respect Retry-After header on status codes defined as
+        :attr:`Retry.RETRY_AFTER_STATUS_CODES` or not.
+
+    :param iterable remove_headers_on_redirect:
+        Sequence of headers to remove from the request when a response
+        indicating a redirect is returned before firing off the redirected
+        request.

+
+        For example, Python's DNS resolver does not obey the timeout specified

+        high CPU load, high swap, the program running at a low priority level,
+        or other behaviors.
+
+        In addition, the read and total timeouts only measure the time between
+        read operations on the socket connecting the client and the server,
+        not the total amount of time for the request to return a complete
+        response. For most requests, the timeout is raised because the server
+        has not sent the first byte in the specified time. This is not always
+        the case; if a server streams one byte every fifteen seconds, a timeout
+        of 20 seconds will not trigger, even though the request will take
+        several minutes to complete.
+
+        If your goal is to cut off any request after a set amount of wall clock

+# There are two types of APIs you can use for waiting on sockets: the fancy
+# modern stateful APIs like epoll/kqueue, and the older stateless APIs like
+# select/poll. The stateful APIs are more efficient when you have a lots of
+# sockets to keep track of, because you can set them up once and then use them
+# lots of times. But we only ever want to wait on a single socket at a time
+# and don't want to keep track of state, so the stateless APIs are actually
+# more efficient. So we want to use select() or poll().
+#
+# Now, how do we choose between select() and poll()? On traditional Unixes,
+# select() has a strange calling convention that makes it slow, or fail
+# altogether, for high-numbered file descriptors. The point of poll() is to fix
+# that, so on Unixes, we prefer poll().
+#
+# On Windows, there is no poll() (or at least Python doesn't provide a wrapper
+# for it), but that's OK, because on Windows, select() doesn't have this
+# strange calling convention; plain select() works fine.
+#
+# So: on Windows we use select(), and everywhere else we use poll(). We also
+# fall back to select() in case poll() is somehow broken or missing.

+Package resource API
+--------------------
+
+A resource is a logical file contained within a package, or a logical
+subdirectory thereof.  The package resource API expects resource names
+to have their path parts separated with ``/``, *not* whatever the local
+path separator is.  Do not use os.path operations to manipulate resource
+names being passed into the API.
+
+The package resource API is designed to work with normal filesystem packages,
+.egg files, and unpacked .egg files.  It can also work in a limited way with
+.zip files and with custom PEP 302 loaders that support the ``get_data()``
+method.

+pyparsing module - Classes and methods to define and execute parsing grammars
+=============================================================================
+
+The pyparsing module is an alternative approach to creating and executing simple grammars,
+vs. the traditional lex/yacc approach, or the use of regular expressions.  With pyparsing, you
+don't need to learn a new syntax for defining grammars or matching expressions - the parsing module
+provides a library of classes that you use to construct the grammar directly in Python.
+
+Here is a program to parse "Hello, World!" (or any greeting of the form 
+C{"<salutation>, <addressee>!"}), built up using L{Word}, L{Literal}, and L{And} elements 
+(L{'+'<ParserElement.__add__>} operator gives L{And} expressions, strings are auto-converted to
+L{Literal} expressions)::
+
+    from pyparsing import Word, alphas
+
+    # define grammar of a greeting
+    greet = Word(alphas) + "," + Word(alphas) + "!"
+
+    hello = "Hello, World!"
+    print (hello, "->", greet.parseString(hello))
+
+The program outputs the following::
+
+    Hello, World! -> ['Hello', ',', 'World', '!']
+
+The Python representation of the grammar is quite readable, owing to the self-explanatory
+class names, and the use of '+', '|' and '^' operators.
+
+The L{ParseResults} object returned from L{ParserElement.parseString<ParserElement.parseString>} can be accessed as a nested list, a dictionary, or an
+object with named attributes.
+
+The pyparsing module handles some of the problems that are typically vexing when writing text parsers:
+ - extra or missing whitespace (the above program will also handle "Hello,World!", "Hello  ,  World  !", etc.)
+ - quoted strings
+ - embedded comments
+
+
+Getting Started -
+-----------------
+Visit the classes L{ParserElement} and L{ParseResults} to see the base classes that most other pyparsing
+classes inherit from. Use the docstrings for examples of how to:
+ - construct literal match expressions from L{Literal} and L{CaselessLiteral} classes
+ - construct character word-group expressions using the L{Word} class
+ - see how to create repetitive expressions using L{ZeroOrMore} and L{OneOrMore} classes

+           instead of re-executing parsing/validating code.  Memoizing is done of

+

+            
+           This speedup may break existing programs that use parse actions that

+           you first import pyparsing.  To activate the packrat feature, your

+           C{enablePackrat} before calling C{psyco.full()}.  If you do not do this,
+           Python will crash.  For best results, call C{enablePackrat()} immediately

+    Token for matching words composed of allowed character sets.
+    Defined with string containing all allowed initial characters,
+    an optional string containing allowed body characters (if omitted,
+    defaults to the initial character set), and an optional minimum,
+    maximum, and/or exact length.  The default value for C{min} is 1 (a
+    minimum value < 1 is not valid); the default values for C{max} and C{exact}
+    are 0, meaning no maximum or exact length restriction. An optional
+    C{excludeChars} parameter can list characters that might be found in 
+    the input C{bodyChars} string; useful to define a word of all printables
+    except for one or two characters, for instance.
+    
+    L{srange} is useful for defining custom character set strings for defining 
+    C{Word} expressions, using range notation from regular expression character sets.
+    
+    A common mistake is to use C{Word} to match a specific literal string, as in 
+    C{Word("Address")}. Remember that C{Word} uses the string argument to define
+    I{sets} of matchable characters. This expression would match "Add", "AAA",
+    "dAred", or any other word made up of the characters 'A', 'd', 'r', 'e', and 's'.
+    To match an exact literal string, use L{Literal} or L{Keyword}.
+
+    pyparsing includes helper strings for building Words:
+     - L{alphas}
+     - L{nums}
+     - L{alphanums}
+     - L{hexnums}
+     - L{alphas8bit} (alphabetic characters in ASCII range 128-255 - accented, tilded, umlauted, etc.)
+     - L{punc8bit} (non-alphabetic characters in ASCII range 128-255 - currency, symbols, superscripts, diacriticals, etc.)
+     - L{printables} (any non-whitespace character)
+
+    Example::

+# This implements an LR parser that is constructed from grammar rules defined
+# as Python functions. The grammer is specified by supplying the BNF inside
+# Python documentation strings.  The inspiration for this technique was borrowed
+# from John Aycock's Spark parsing system.  PLY might be viewed as cross between
+# Spark and the GNU bison utility.
+#
+# The current implementation is only somewhat object-oriented. The
+# LR parser itself is defined in terms of an object (which allows multiple
+# parsers to co-exist).  However, most of the variables used during table
+# construction are defined in terms of global variables.  Users shouldn't
+# notice unless they are trying to define multiple parsers at the same
+# time using threads (in which case they should have their head examined).
+#
+# This implementation supports both SLR and LALR(1) parsing.  LALR(1)
+# support was originally implemented by Elias Ioup (ezioup@alumni.uchicago.edu),
+# using the algorithm found in Aho, Sethi, and Ullman "Compilers: Principles,
+# Techniques, and Tools" (The Dragon Book).  LALR(1) has since been replaced
+# by the more efficient DeRemer and Pennello algorithm.
+#
+# :::::::: WARNING :::::::
+#
+# Construction of LR parsing tables is fairly complicated and expensive.
+# To make this module run fast, a *LOT* of work has been put into
+# optimization---often at the expensive of readability and what might
+# consider to be good Python "coding style."   Modify the code at your
+# own risk!

+# Requests
+
+**Requests** is a simple, yet elegant, HTTP library.
+
+```python
+>>> import requests
+>>> r = requests.get('https://httpbin.org/basic-auth/user/pass', auth=('user', 'pass'))
+>>> r.status_code
+200
+>>> r.headers['content-type']
+'application/json; charset=utf8'
+>>> r.encoding
+'utf-8'
+>>> r.text
+'{"authenticated": true, ...'
+>>> r.json()
+{'authenticated': True, ...}
+```
+
+Requests allows you to send HTTP/1.1 requests extremely easily. There’s no need to manually add query strings to your URLs, or to form-encode your `PUT` & `POST` data — but nowadays, just use the `json` method!
+
+Requests is one of the most downloaded Python packages today, pulling in around `30M downloads / week`— according to GitHub, Requests is currently [depended upon](https://github.com/psf/requests/network/dependents?package_id=UGFja2FnZS01NzA4OTExNg%3D%3D) by `1,000,000+` repositories. You may certainly put your trust in this code.

+
+## Cloning the repository
+
+When cloning the Requests repository, you may need to add the `-c
+fetch.fsck.badTimezone=ignore` flag to avoid an error about a bad commit (see
+[this issue](https://github.com/psf/requests/issues/2690) for more background):
+
+```shell
+git clone -c fetch.fsck.badTimezone=ignore https://github.com/psf/requests.git
+```
+
+You can also apply this setting to your global Git config:
+
+```shell
+git config --global fetch.fsck.badTimezone ignore
+```

+
+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.
+
+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the
+      outstanding shares, or (iii) beneficial ownership of such entity.
+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "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
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   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,
+      where such license applies only to those patent claims licensable
+      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.

+Requests HTTP Library
+~~~~~~~~~~~~~~~~~~~~~
+
+Requests is an HTTP library, written in Python, for human beings.
+Basic GET usage:
+
+   >>> import requests
+   >>> r = requests.get('https://www.python.org')
+   >>> r.status_code
+   200
+   >>> b'Python is a programming language' in r.content
+   True
+
+... or POST:
+
+   >>> payload = dict(key1='value1', key2='value2')
+   >>> r = requests.post('https://httpbin.org/post', data=payload)
+   >>> print(r.text)
+   {
+     ...
+     "form": {
+       "key1": "value1",
+       "key2": "value2"
+     },
+     ...
+   }
+
+The other HTTP methods are supported - see `requests.api`. Full documentation
+is at <https://requests.readthedocs.io>.

+        to use to select a connection from a given urllib3 Connection Pool.
+
+        The SSL related pool key arguments are not consistently set. As of
+        this writing, use the following to determine what keys may be in that
+        dictionary:
+
+        * If ``verify`` is ``True``, ``"ssl_context"`` will be set and will be the
+          default Requests SSL Context
+        * If ``verify`` is ``False``, ``"ssl_context"`` will not be set but
+          ``"cert_reqs"`` will be set
+        * If ``verify`` is a string, (i.e., it is a user-specified trust bundle)
+          ``"ca_certs"`` will be set if the string is not a directory recognized
+          by :py:func:`os.path.isdir`, otherwise ``"ca_certs_dir"`` will be
+          set.
+        * If ``"cert"`` is specified, ``"cert_file"`` will always be set. If
+          ``"cert"`` is a tuple with a second item, ``"key_file"`` will also
+          be present
+
+        To override these settings, one may subclass this class, call this
+        method and use the above logic to change parameters as desired. For
+        example, if one wishes to use a custom :py:class:`ssl.SSLContext` one
+        must both set ``"ssl_context"`` and based on what else they require,

+    # 'isinstance'.  In concrete CCompiler subclasses, 'compiler_type'

+       Provides a 'warn()' method so you can generate warning messages that
+       report physical line number, even if the logical line in question
+       spans multiple physical lines.  Also provides 'unreadline()' for
+       implementing line-at-a-time lookahead.
+
+       Constructor is called as:
+
+           TextFile (filename=None, file=None, **options)
+
+       It bombs (RuntimeError) if both 'filename' and 'file' are None;
+       'filename' should be a string, and 'file' a file object (or
+       something that provides 'readline()' and 'close()' methods).  It is
+       recommended that you supply at least 'filename', so that TextFile
+       can include it in warning messages.  If 'file' is not supplied,
+       TextFile creates its own using 'io.open()'.
+
+       The options are all boolean, and affect the value returned by
+       'readline()':
+         strip_comments [default: true]
+           strip from "#" to end-of-line, as well as any whitespace
+           leading up to the "#" -- unless it is escaped by a backslash
+         lstrip_ws [default: false]
+           strip leading whitespace from each line before returning it
+         rstrip_ws [default: true]
+           strip trailing whitespace (including line terminator!) from
+           each line before returning it
+         skip_blanks [default: true}
+           skip lines that are empty *after* stripping comments and
+           whitespace.  (If both lstrip_ws and rstrip_ws are false,
+           then some lines may consist of solely whitespace: these will
+           *not* be skipped, even if 'skip_blanks' is true.)
+         join_lines [default: false]
+           if a backslash is the last non-newline character on a line
+           after stripping comments and whitespace, join the following line
+           to it to form one "logical line"; if N consecutive lines end
+           with a backslash, then N+1 physical lines will be joined to
+           form one logical line.
+         collapse_join [default: false]
+           strip leading whitespace from lines that are joined to their
+           predecessor; only matters if (join_lines and not lstrip_ws)
+         errors [default: 'strict']
+           error handler used to decode the file content
+
+       Note that since 'rstrip_ws' can strip the trailing newline, the
+       semantics of 'readline()' must differ from those of the builtin file
+       object's 'readline()' method!  In particular, 'readline()' returns
+       None for end-of-file: an empty string might just be a blank line (or
+       an all-whitespace line), if 'rstrip_ws' is true but 'skip_blanks' is

+    """Version numbering for anal retentives and software idealists.
+    Implements the standard interface for version number classes as
+    described above.  A version number consists of two or three
+    dot-separated numeric components, with an optional "pre-release" tag
+    on the end.  The pre-release tag consists of the letter 'a' or 'b'
+    followed by a number.  If the numeric components of two version
+    numbers are equal, then one with a pre-release tag will always
+    be deemed earlier (lesser) than one without.
+
+    The following are valid version numbers (shown in the order that
+    would be obtained by sorting according to the supplied cmp function):
+
+        0.4       0.4.0  (these two are equivalent)
+        0.4.1
+        0.5a1

+        0.5

+        1.0.4a3
+        1.0.4b1

+        1.3.a4
+        1.3pl1

+
+# The rules according to Greg Stein:
+# 1) a version number has 1 or more numbers separated by a period or by
+#    sequences of letters. If only periods, then these are compared
+#    left-to-right to determine an ordering.
+# 2) sequences of letters are part of the tuple for comparison and are
+#    compared lexicographically
+# 3) recognize the numeric components may have leading zeroes
+#
+# The LooseVersion class below implements these rules: a version number
+# string is split up into a tuple of integer and string components, and
+# comparison is a simple tuple comparison.  This means that version
+# numbers behave in a predictable and obvious way, but a way that might
+# not necessarily be how people *want* version numbers to behave.  There
+# wouldn't be a problem if people could stick to purely numeric version
+# numbers: just split on period and compare the numbers as tuples.
+# However, people insist on putting letters into their version numbers;
+# the most common purpose seems to be:
+#   - indicating a "pre-release" version
+#     ('alpha', 'beta', 'a', 'b', 'pre', 'p')
+#   - indicating a post-release patch ('p', 'pl', 'patch')
+# but of course this can't cover all version number schemes, and there's
+# no way to know what a programmer means without asking him.
+#
+# The problem is what to do with letters (and other non-numeric
+# characters) in a version number.  The current implementation does the
+# obvious and predictable thing: keep them as strings and compare
+# lexically within a tuple comparison.  This has the desired effect if
+# an appended letter sequence implies something "post-release":
+# eg. "0.99" < "0.99pl14" < "1.0", and "5.001" < "5.001m" < "5.002".
+#
+# However, if letters in a version number imply a pre-release version,
+# the "obvious" thing isn't correct.  Eg. you would expect that
+# "1.5.1" < "1.5.2a2" < "1.5.2", but under the tuple/lexical comparison
+# implemented here, this just isn't so.
+#
+# Two possible solutions come to mind.  The first is to tie the
+# comparison algorithm to a particular set of semantic rules, as has
+# been done in the StrictVersion class above.  This works great as long
+# as everyone can go along with bondage and discipline.  Hopefully a
+# (large) subset of Python module programmers will agree that the
+# particular flavour of bondage and discipline provided by StrictVersion
+# provides enough benefit to be worth using, and will submit their
+# version numbering scheme to its domination.  The free-thinking
+# anarchists in the lot will never give in, though, and something needs
+# to be done to accommodate them.
+#
+# Perhaps a "moderately strict" version class could be implemented that
+# lets almost anything slide (syntactically), and makes some heuristic
+# assumptions about non-digits in version number strings.  This could
+# sink into special-case-hell, though; if I was as talented and
+# idiosyncratic as Larry Wall, I'd go ahead and implement a class that
+# somehow knows that "1.2.1" < "1.2.2a2" < "1.2.2" < "1.2.2pl3", and is
+# just as happy dealing with things like "2g6" and "1.13++".  I don't
+# think I'm smart enough to do it right though.
+#
+# In any case, I've coded the test suite for this module (see
+# ../test/test_version.py) specifically to fail on things like comparing
+# "1.2a2" and "1.2".  That's not because the *code* is doing anything
+# wrong, it's because the simple, obvious design doesn't match my
+# complicated, hairy expectations for real-world version numbers.  It
+# would be a snap to fix the test suite to say, "Yep, LooseVersion does
+# the Right Thing" (ie. the code matches the conception).  But I'd rather
+# have a conception that matches common notions about version numbers.

+pyparsing module - Classes and methods to define and execute parsing grammars
+=============================================================================
+
+The pyparsing module is an alternative approach to creating and executing simple grammars,
+vs. the traditional lex/yacc approach, or the use of regular expressions.  With pyparsing, you
+don't need to learn a new syntax for defining grammars or matching expressions - the parsing module
+provides a library of classes that you use to construct the grammar directly in Python.
+
+Here is a program to parse "Hello, World!" (or any greeting of the form 
+C{"<salutation>, <addressee>!"}), built up using L{Word}, L{Literal}, and L{And} elements 
+(L{'+'<ParserElement.__add__>} operator gives L{And} expressions, strings are auto-converted to
+L{Literal} expressions)::
+
+    from pyparsing import Word, alphas
+
+    # define grammar of a greeting
+    greet = Word(alphas) + "," + Word(alphas) + "!"
+
+    hello = "Hello, World!"
+    print (hello, "->", greet.parseString(hello))
+
+The program outputs the following::
+
+    Hello, World! -> ['Hello', ',', 'World', '!']
+
+The Python representation of the grammar is quite readable, owing to the self-explanatory
+class names, and the use of '+', '|' and '^' operators.
+
+The L{ParseResults} object returned from L{ParserElement.parseString<ParserElement.parseString>} can be accessed as a nested list, a dictionary, or an
+object with named attributes.
+
+The pyparsing module handles some of the problems that are typically vexing when writing text parsers:
+ - extra or missing whitespace (the above program will also handle "Hello,World!", "Hello  ,  World  !", etc.)
+ - quoted strings
+ - embedded comments
+
+
+Getting Started -
+-----------------
+Visit the classes L{ParserElement} and L{ParseResults} to see the base classes that most other pyparsing
+classes inherit from. Use the docstrings for examples of how to:
+ - construct literal match expressions from L{Literal} and L{CaselessLiteral} classes
+ - construct character word-group expressions using the L{Word} class
+ - see how to create repetitive expressions using L{ZeroOrMore} and L{OneOrMore} classes
+ - use L{'+'<And>}, L{'|'<MatchFirst>}, L{'^'<Or>}, and L{'&'<Each>} operators to combine simple expressions into more complex ones
+ - associate names with your parsed results using L{ParserElement.setResultsName}
+ - find some helpful expression short-cuts like L{delimitedList} and L{oneOf}
+ - find more useful common expressions in the L{pyparsing_common} namespace class

+           often in many complex grammars) can immediately return a cached value,
+           instead of re-executing parsing/validating code.  Memoizing is done of
+           both valid results and parsing exceptions.
+           
+           Parameters:
+            - cache_size_limit - (default=C{128}) - if an integer value is provided
+              will limit the size of the packrat cache; if None is passed, then
+              the cache size will be unbounded; if 0 is passed, the cache will
+              be effectively disabled.
+            
+           This speedup may break existing programs that use parse actions that
+           have side-effects.  For this reason, packrat parsing is disabled when
+           you first import pyparsing.  To activate the packrat feature, your
+           program must call the class method C{ParserElement.enablePackrat()}.  If
+           your program uses C{psyco} to "compile as you go", you must call
+           C{enablePackrat} before calling C{psyco.full()}.  If you do not do this,
+           Python will crash.  For best results, call C{enablePackrat()} immediately
+           after importing pyparsing.

+    defaults to the initial character set), and an optional minimum,
+    maximum, and/or exact length.  The default value for C{min} is 1 (a
+    minimum value < 1 is not valid); the default values for C{max} and C{exact}
+    are 0, meaning no maximum or exact length restriction. An optional
+    C{excludeChars} parameter can list characters that might be found in

+    
+    L{srange} is useful for defining custom character set strings for defining 
+    C{Word} expressions, using range notation from regular expression character sets.
+    
+    A common mistake is to use C{Word} to match a specific literal string, as in 
+    C{Word("Address")}. Remember that C{Word} uses the string argument to define
+    I{sets} of matchable characters. This expression would match "Add", "AAA",
+    "dAred", or any other word made up of the characters 'A', 'd', 'r', 'e', and 's'.
+    To match an exact literal string, use L{Literal} or L{Keyword}.
+
+    pyparsing includes helper strings for building Words:
+     - L{alphas}
+     - L{nums}
+     - L{alphanums}
+     - L{hexnums}
+     - L{alphas8bit} (alphabetic characters in ASCII range 128-255 - accented, tilded, umlauted, etc.)
+     - L{punc8bit} (non-alphabetic characters in ASCII range 128-255 - currency, symbols, superscripts, diacriticals, etc.)

+    Call C{withAttribute} with a series of attribute names and values. Specify the list
+    of filter attributes names and values as:
+     - keyword arguments, as in C{(align="right")}, or
+     - as an explicit dict with C{**} operator, when an attribute name is also a Python
+          reserved word, as in C{**{"class":"Customer", "align":"right"}}
+     - a list of name-value tuples, as in ( ("ns1:class", "Customer"), ("ns2:align","right") )
+    For attribute names with a namespace prefix, you must use the second form.  Attribute
+    names are matched insensitive to upper/lower case.
+       
+    If just testing for C{class} (with or without a namespace), use C{L{withClass}}.
+
+    To verify that the attribute exists, but without specifying a value, pass
+    C{withAttribute.ANY_VALUE} as the value.

+    Helper method for constructing grammars of expressions made up of

+       - parseAction is the parse action to be associated with
+          expressions matching this operator expression (the
+          parse action tuple member may be omitted); if the parse action

+"""A PEP 517 interface to setuptools
+
+Previously, when a user or a command line tool (let's call it a "frontend")
+needed to make a request of setuptools to take a certain action, for
+example, generating a list of installation requirements, the frontend would
+would call "setup.py egg_info" or "setup.py bdist_wheel" on the command line.
+
+PEP 517 defines a different method of interfacing with setuptools. Rather
+than calling "setup.py" directly, the frontend should:
+
+  1. Set the current directory to the directory with a setup.py file
+  2. Import this module into a safe python interpreter (one in which
+     setuptools can potentially set global variables or crash hard).
+  3. Call one of the functions defined in PEP 517.
+
+What each function does is defined in PEP 517. However, here is a "casual"
+definition of the functions (this definition should not be relied on for
+bug reports or API stability):
+
+  - `build_wheel`: build a wheel in the folder and return the basename
+  - `get_requires_for_build_wheel`: get the `setup_requires` to build
+  - `prepare_metadata_for_build_wheel`: get the `install_requires`
+  - `build_sdist`: build an sdist in the folder and return the basename
+  - `get_requires_for_build_sdist`: get the `setup_requires` to build
+
+Again, this is not a formal definition! Just a "taste" of the module.

+
+        You are attempting to install a package to a directory that is not
+        on PYTHONPATH and which Python does not read ".pth" files from.  The
+        installation directory you specified (via --install-dir, --prefix, or
+        the distutils default setting) was:
+
+            %s
+
+        and your PYTHONPATH environment variable currently contains:
+
+            %r
+
+        Here are some of your options for correcting the problem:
+
+        * You can choose a different installation directory, i.e., one that is
+          on PYTHONPATH or supports .pth files
+
+        * You can add the installation directory to the PYTHONPATH environment
+          variable.  (It must then also be on PYTHONPATH whenever you run
+          Python and want to use the package(s) you are installing.)
+
+        * You can set up the installation directory to support ".pth" files by
+          using one of the approaches described here:
+
+          https://setuptools.pypa.io/en/latest/deprecated/easy_install.html#custom-installation-locations

+
+    zipimport.zipimporter objects are Python loaders charged with importing
+    data packaged inside zip archives. If stale loaders referencing the
+    original distribution, are left behind, they can fail to load modules from
+    the replacement distribution. E.g. if an old zipimport.zipimporter instance
+    is used to load data from a new zipped egg archive, it may cause the
+    operation to attempt to locate the requested data in the wrong location -
+    one indicated by the original distribution's zip archive directory

+    them down and remove them one by one, by updating their shared cached zip
+    archive directory information. This, of course, assumes that the
+    replacement distribution is packaged as a zipped egg.
+
+    If not asked to fix existing zipimport.zipimporter instances, we still do
+    our best to clear any remaining zipimport.zipimporter related cached data
+    that might somehow later get used when attempting to load data from the new

+    tracking down such remaining stale data, we can not catch every conceivable
+    usage from here, and we clear only those that we know of and have found to
+    cause problems if left alive. Any remaining caches should be updated by

+    """Distribution with support for tests and package data
+
+    This is an enhanced version of 'distutils.dist.Distribution' that
+    effectively adds the following new optional keyword arguments to 'setup()':
+
+     'install_requires' -- a string or sequence of strings specifying project
+        versions that the distribution requires when installed, in the format
+        used by 'pkg_resources.require()'.  They will be installed
+        automatically when the package is installed.  If you wish to use
+        packages that are not available in PyPI, or want to give your users an
+        alternate download location, you can add a 'find_links' option to the
+        '[easy_install]' section of your project's 'setup.cfg' file, and then
+        setuptools will scan the listed web pages for links that satisfy the
+        requirements.
+
+     'extras_require' -- a dictionary mapping names of optional "extras" to the
+        additional requirement(s) that using those extras incurs. For example,
+        this::
+
+            extras_require = dict(reST = ["docutils>=0.3", "reSTedit"])
+
+        indicates that the distribution can optionally provide an extra
+        capability called "reST", but it can only be used if docutils and
+        reSTedit are installed.  If the user installs your package using
+        EasyInstall and requests one of your extras, the corresponding
+        additional requirements will be installed if needed.
+
+     'test_suite' -- the name of a test suite to run for the 'test' command.
+        If the user runs 'python setup.py test', the package will be installed,
+        and the named test suite will be run.  The format is the same as
+        would be used on a 'unittest.py' command line.  That is, it is the
+        dotted name of an object to import and call to generate a test suite.
+
+     'package_data' -- a dictionary mapping package names to lists of filenames
+        or globs to use to find data files contained in the named packages.
+        If the dictionary has filenames or globs listed under '""' (the empty
+        string), those names will be searched for in every package, in addition
+        to any names for the specific package.  Data files found using these
+        names/globs will be installed along with the package, in the same
+        location as the package.  Note that globs are allowed to reference
+        the contents of non-package subdirectories, as long as you use '/' as
+        a path separator.  (Globs are automatically converted to
+        platform-specific paths at runtime.)
+
+    In addition to these new keywords, this class also has several new methods
+    for manipulating the distribution's contents.  For example, the 'include()'
+    and 'exclude()' methods can be thought of as in-place add and subtract
+    commands that add or remove packages, modules, extensions, and so on from
+    the distribution.

+
+urllib3 is a powerful, *user-friendly* HTTP client for Python. Much of the
+Python ecosystem already uses urllib3 and you should too.
+urllib3 brings many critical features that are missing from the Python
+standard libraries:
+
+- Thread safety.
+- Connection pooling.
+- Client-side SSL/TLS verification.
+- File uploads with multipart encoding.
+- Helpers for retrying requests and dealing with HTTP redirects.
+- Support for gzip, deflate, brotli, and zstd encoding.
+- Proxy support for HTTP and SOCKS.
+- 100% test coverage.
+
+urllib3 is powerful and easy to use:
+
+```python3
+>>> import urllib3
+>>> resp = urllib3.request("GET", "http://httpbin.org/robots.txt")
+>>> resp.status
+200
+>>> resp.data
+b"User-agent: *\nDisallow: /deny\n"
+```
+
+## Installing
+
+urllib3 can be installed with [pip](https://pip.pypa.io):

+        """
+        Make a request using :meth:`urlopen` with the ``fields`` encoded in
+        the body. This is useful for request methods like POST, PUT, PATCH, etc.
+
+        When ``encode_multipart=True`` (default), then
+        :func:`urllib3.encode_multipart_formdata` is used to encode
+        the payload with the appropriate content type. Otherwise
+        :func:`urllib.parse.urlencode` is used with the
+        'application/x-www-form-urlencoded' content type.
+
+        Multipart encoding must be used when posting files, and it's reasonably
+        safe to use it in other times too. However, it may break request
+        signing, such as with OAuth.
+
+        Supports an optional ``fields`` parameter of key/value strings AND
+        key/filetuple. A filetuple is a (filename, data, MIME type) tuple where
+        the MIME type is optional. For example::
+
+            fields = {
+                'foo': 'bar',
+                'fakefile': ('foofile.txt', 'contents of foofile'),
+                'realfile': ('barfile.txt', open('realfile').read()),
+                'typedfile': ('bazfile.bin', open('bazfile').read(),
+                              'image/jpeg'),
+                'nonamefile': 'contents of nonamefile field',
+            }
+
+        When uploading a file, providing a filename (the first parameter of the
+        tuple) is optional but recommended to best mimic behavior of browsers.
+
+        Note that if ``headers`` are supplied, the 'Content-Type' header will
+        be overwritten because it depends on the dynamic random boundary string
+        which is used to compose the body of the request. The random boundary
+        string can be explicitly set with the ``multipart_boundary`` parameter.
+
+        :param method:
+            HTTP request method (such as GET, POST, PUT, etc.)
+
+        :param url:
+            The URL to perform the request on.
+
+        :param fields:
+            Data to encode and send in the request body.
+
+        :param headers:
+            Dictionary of custom headers to send, such as User-Agent,
+            If-None-Match, etc. If None, pool headers are used. If provided,
+            these headers completely replace any pool-specific headers.
+
+        :param encode_multipart:
+            If True, encode the ``fields`` using the multipart/form-data MIME
+            format.
+
+        :param multipart_boundary:
+            If not specified, then a random boundary will be generated using
+            :func:`urllib3.filepost.choose_boundary`.

+        into :class:`http.client.HTTPConnection`.
+
+    :param timeout:
+        Socket timeout in seconds for each individual connection. This can
+        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.
+
+    :param maxsize:
+        Number of connections to save that can be reused. More than 1 is useful
+        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.
+

+        Parsed proxy URL, should not be used directly, instead, see
+        :class:`urllib3.ProxyManager`

+        Get a connection from the pool and perform an HTTP request. This is the
+        lowest level call for making a request, so you'll need to specify all
+        the raw details.
+
+        .. note::
+
+           More commonly, it's appropriate to use a convenience method
+           such as :meth:`request`.
+
+        .. note::
+
+           `release_conn` will only behave as expected if
+           `preload_content=False` because we want to make
+           `preload_content=False` the default behaviour someday soon without
+           breaking backwards compatibility.
+
+        :param method:
+            HTTP request method (such as GET, POST, PUT, etc.)
+
+        :param url:
+            The URL to perform the request on.
+
+        :param body:
+            Data to send in the request body, either :class:`str`, :class:`bytes`,
+            an iterable of :class:`str`/:class:`bytes`, or a file-like object.
+
+        :param headers:
+            Dictionary of custom headers to send, such as User-Agent,
+            If-None-Match, etc. If None, pool headers are used. If provided,
+            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.
+
+            If ``None`` (default) will retry 3 times, see ``Retry.DEFAULT``. 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 bool preload_content:
+            If True, the response's body will be preloaded into memory.
+
+        :param bool decode_content:
+            If True, will attempt to decode the body based on the
+            'content-encoding' header.
+
+        :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 ``preload_content``
+            which defaults to ``True``.
+
+        :param bool 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.

+Support for streaming http requests in emscripten.
+
+A few caveats -
+
+If your browser (or Node.js) has WebAssembly JavaScript Promise Integration enabled
+https://github.com/WebAssembly/js-promise-integration/blob/main/proposals/js-promise-integration/Overview.md
+*and* you launch pyodide using `pyodide.runPythonAsync`, this will fetch data using the
+JavaScript asynchronous fetch api (wrapped via `pyodide.ffi.call_sync`). In this case
+timeouts and streaming should just work.
+
+Otherwise, it uses a combination of XMLHttpRequest and a web-worker for streaming.
+
+This approach has several caveats:
+
+Firstly, you can't do streaming http in the main UI thread, because atomics.wait isn't allowed.
+Streaming only works if you're running pyodide in a web worker.
+
+Secondly, this uses an extra web worker and SharedArrayBuffer to do the asynchronous fetch
+operation, so it requires that you have crossOriginIsolation enabled, by serving over https
+(or from localhost) with the two headers below set:
+
+    Cross-Origin-Opener-Policy: same-origin
+    Cross-Origin-Embedder-Policy: require-corp
+
+You can tell if cross origin isolation is successfully enabled by looking at the global crossOriginIsolated variable in
+JavaScript console. If it isn't, streaming requests will fallback to XMLHttpRequest, i.e. getting the whole
+request into a buffer and then returning it. it shows a warning in the JavaScript console in this case.
+
+Finally, the webworker which does the streaming fetch is created on initial import, but will only be started once
+control is returned to javascript. Call `await wait_for_streaming_ready()` to wait for streaming fetch.
+
+NB: in this code, there are a lot of JavaScript objects. They are named js_*
+to make it clear what type of object they are.

+Module for using pyOpenSSL as a TLS backend. This module was relevant before
+the standard library ``ssl`` module supported SNI, but now that we've dropped
+support for Python 2.7 all relevant Python versions support SNI so
+**this module is no longer recommended**.
+
+This needs the following packages installed:
+
+* `pyOpenSSL`_ (tested with 16.0.0)
+* `cryptography`_ (minimum 1.3.4, from pyopenssl)
+* `idna`_ (minimum 2.0)
+
+However, pyOpenSSL depends on cryptography, so while we use all three directly here we
+end up having relatively few packages required.
+
+You can install them with the following command:
+
+.. code-block:: bash
+
+    $ python -m pip install pyopenssl cryptography idna
+
+To activate certificate checking, call
+:func:`~urllib3.contrib.pyopenssl.inject_into_urllib3` from your Python code
+before you begin making HTTP requests. This can be done in a ``sitecustomize``
+module, or at any other time before your application begins using ``urllib3``,
+like this:
+
+.. code-block:: python
+
+    try:
+        import urllib3.contrib.pyopenssl
+        urllib3.contrib.pyopenssl.inject_into_urllib3()
+    except ImportError:
+        pass
+
+.. _pyopenssl: https://www.pyopenssl.org

+"""
+This module contains provisional support for SOCKS proxies from within
+urllib3. This module supports SOCKS4, SOCKS4A (an extension of SOCKS4), and
+SOCKS5. To enable its functionality, either install PySocks or install this
+module with the ``socks`` extra.
+
+The SOCKS implementation supports the full range of urllib3 features. It also
+supports the following SOCKS features:
+
+- SOCKS4A (``proxy_url='socks4a://...``)
+- SOCKS4 (``proxy_url='socks4://...``)
+- SOCKS5 with remote DNS (``proxy_url='socks5h://...``)
+- SOCKS5 with local DNS (``proxy_url='socks5://...``)
+- Usernames and passwords for the SOCKS proxy
+
+.. note::
+   It is recommended to use ``socks5h://`` or ``socks4a://`` schemes in
+   your ``proxy_url`` to ensure that DNS resolution is done from the remote
+   server instead of client-side when connecting to a domain name.
+
+SOCKS4 supports IPv4 and domain names with the SOCKS4A extension. SOCKS5
+supports IPv4, IPv6, and domain names.
+
+When connecting to a SOCKS4 proxy the ``username`` portion of the ``proxy_url``
+will be sent as the ``userid`` section of the SOCKS request:
+
+.. code-block:: python
+
+    proxy_url="socks4a://<userid>@proxy-host"
+
+When connecting to a SOCKS5 proxy the ``username`` and ``password`` portion
+of the ``proxy_url`` will be sent as the username/password to authenticate
+with the proxy:
+
+.. code-block:: python
+
+    proxy_url="socks5h://<username>:<password>@proxy-host"

+
+    Each retry attempt will create a new Retry object with updated values, so
+    they can be safely reused.
+
+    Retries can be defined as a default for a pool:
+
+    .. code-block:: python
+
+        retries = Retry(connect=5, read=2, redirect=5)
+        http = PoolManager(retries=retries)

+
+    Or per-request (which overrides the default for the pool):
+
+    .. code-block:: python
+
+        response = http.request("GET", "https://example.com/", retries=Retry(10))
+
+    Retries can be disabled by passing ``False``:
+
+    .. code-block:: python
+
+        response = http.request("GET", "https://example.com/", retries=False)
+
+    Errors will be wrapped in :class:`~urllib3.exceptions.MaxRetryError` unless
+    retries are disabled, in which case the causing exception will be raised.
+
+    :param int total:
+        Total number of retries to allow. Takes precedence over other counts.
+
+        Set to ``None`` to remove this constraint and fall back on other
+        counts.
+
+        Set to ``0`` to fail on the first retry.
+
+        Set to ``False`` to disable and imply ``raise_on_redirect=False``.
+
+    :param int connect:
+        How many connection-related errors to retry on.
+
+        These are errors raised before the request is sent to the remote server,
+        which we assume has not triggered the server to process the request.
+
+        Set to ``0`` to fail on the first retry of this type.
+
+    :param int read:
+        How many times to retry on read errors.
+
+        These errors are raised after the request was sent to the server, so the
+        request may have side-effects.
+
+        Set to ``0`` to fail on the first retry of this type.
+
+    :param int redirect:
+        How many redirects to perform. Limit this to avoid infinite redirect
+        loops.
+
+        A redirect is a HTTP response with a status code 301, 302, 303, 307 or
+        308.
+
+        Set to ``0`` to fail on the first retry of this type.
+
+        Set to ``False`` to disable and imply ``raise_on_redirect=False``.
+
+    :param int status:
+        How many times to retry on bad status codes.
+
+        These are retries made on responses, where status code matches
+        ``status_forcelist``.
+
+        Set to ``0`` to fail on the first retry of this type.
+
+    :param int other:
+        How many times to retry on other errors.
+
+        Other errors are errors that are not connect, read, redirect or status errors.
+        These errors might be raised after the request was sent to the server, so the
+        request might have side-effects.
+
+        Set to ``0`` to fail on the first retry of this type.
+
+        If ``total`` is not set, it's a good idea to set this to 0 to account
+        for unexpected edge cases and avoid infinite retry loops.
+
+    :param Collection allowed_methods:
+        Set of uppercased HTTP method verbs that we should retry on.
+
+        By default, we only retry on methods which are considered to be
+        idempotent (multiple requests with the same parameters end with the
+        same state). See :attr:`Retry.DEFAULT_ALLOWED_METHODS`.
+
+        Set to a ``None`` value to retry on any verb.
+
+    :param Collection status_forcelist:
+        A set of integer HTTP status codes that we should force a retry on.
+        A retry is initiated if the request method is in ``allowed_methods``
+        and the response status code is in ``status_forcelist``.
+
+        By default, this is disabled with ``None``.
+
+    :param float backoff_factor:
+        A backoff factor to apply between attempts after the second try
+        (most errors are resolved immediately by a second try without a
+        delay). urllib3 will sleep for::
+
+            {backoff factor} * (2 ** ({number of previous retries}))
+
+        seconds. If `backoff_jitter` is non-zero, this sleep is extended by::
+
+            random.uniform(0, {backoff jitter})
+
+        seconds. For example, if the backoff_factor is 0.1, then :func:`Retry.sleep` will
+        sleep for [0.0s, 0.2s, 0.4s, 0.8s, ...] between retries. No backoff will ever
+        be longer than `backoff_max`.
+
+        By default, backoff is disabled (factor set to 0).
+
+    :param bool raise_on_redirect: Whether, if the number of redirects is
+        exhausted, to raise a MaxRetryError, or to return a response with a
+        response code in the 3xx range.
+
+    :param bool raise_on_status: Similar meaning to ``raise_on_redirect``:
+        whether we should raise an exception, or return a response,
+        if status falls in ``status_forcelist`` range and retries have
+        been exhausted.
+
+    :param tuple history: The history of the request encountered during
+        each call to :meth:`~Retry.increment`. The list is in the order
+        the requests occurred. Each list item is of class :class:`RequestHistory`.
+
+    :param bool respect_retry_after_header:
+        Whether to respect Retry-After header on status codes defined as
+        :attr:`Retry.RETRY_AFTER_STATUS_CODES` or not.
+
+    :param Collection remove_headers_on_redirect:
+        Sequence of headers to remove from the request when a response
+        indicating a redirect is returned before firing off the redirected
+        request.

+
+        For example, Python's DNS resolver does not obey the timeout specified
+        on the socket. Other factors that can affect total request time include
+        high CPU load, high swap, the program running at a low priority level,
+        or other behaviors.
+
+        In addition, the read and total timeouts only measure the time between
+        read operations on the socket connecting the client and the server,
+        not the total amount of time for the request to return a complete
+        response. For most requests, the timeout is raised because the server
+        has not sent the first byte in the specified time. This is not always
+        the case; if a server streams one byte every fifteen seconds, a timeout
+        of 20 seconds will not trigger, even though the request will take
+        several minutes to complete.

+# lots of times. But we only ever want to wait on a single socket at a time
+# and don't want to keep track of state, so the stateless APIs are actually
+# more efficient. So we want to use select() or poll().
+#
+# Now, how do we choose between select() and poll()? On traditional Unixes,
+# select() has a strange calling convention that makes it slow, or fail
+# altogether, for high-numbered file descriptors. The point of poll() is to fix
+# that, so on Unixes, we prefer poll().
+#
+# On Windows, there is no poll() (or at least Python doesn't provide a wrapper
+# for it), but that's OK, because on Windows, select() doesn't have this
+# strange calling convention; plain select() works fine.

+# Werkzeug
+
+*werkzeug* German noun: "tool". Etymology: *werk* ("work"), *zeug* ("stuff")
+
+Werkzeug is a comprehensive [WSGI][] web application library. It began as
+a simple collection of various utilities for WSGI applications and has
+become one of the most advanced WSGI utility libraries.
+
+It includes:
+
+-   An interactive debugger that allows inspecting stack traces and
+    source code in the browser with an interactive interpreter for any
+    frame in the stack.
+-   A full-featured request object with objects to interact with
+    headers, query args, form data, files, and cookies.
+-   A response object that can wrap other WSGI applications and handle
+    streaming data.
+-   A routing system for matching URLs to endpoints and generating URLs
+    for endpoints, with an extensible system for capturing variables
+    from URLs.
+-   HTTP utilities to handle entity tags, cache control, dates, user
+    agents, cookies, files, and more.
+-   A threaded WSGI server for use while developing applications
+    locally.
+-   A test client for simulating HTTP requests during testing without
+    requiring running a server.
+
+Werkzeug doesn't enforce any dependencies. It is up to the developer to
+choose a template engine, database adapter, and even how to handle
+requests. It can be used to build all sorts of end user applications
+such as blogs, wikis, or bulletin boards.
+
+[Flask][] wraps Werkzeug, using it to handle the details of WSGI while
+providing more structure and patterns for defining powerful
+applications.

+
+
+## A Simple Example
+
+```python
+# save this as app.py
+from werkzeug.wrappers import Request, Response
+
+@Request.application
+def application(request: Request) -> Response:
+    return Response("Hello, World!")
+
+if __name__ == "__main__":
+    from werkzeug.serving import run_simple
+    run_simple("127.0.0.1", 5000, application)
+```
+
+```
+$ python -m app
+  * Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)
+```

+    multiple values for the same key which is for example used by the parsing
+    functions in the wrappers.  This is necessary because some HTML form
+    elements pass multiple values for the same key.
+
+    :class:`MultiDict` implements all standard dictionary methods.
+    Internally, it saves all values for a key as a list, but the standard dict
+    access methods will only return the first value for a key. If you want to
+    gain access to the other values, too, you have to use the `list` methods as
+    explained below.
+
+    Basic Usage:
+
+    >>> d = MultiDict([('a', 'b'), ('a', 'c')])
+    >>> d
+    MultiDict([('a', 'b'), ('a', 'c')])
+    >>> d['a']
+    'b'
+    >>> d.getlist('a')
+    ['b', 'c']
+    >>> 'a' in d
+    True
+
+    It behaves like a normal dict thus all dict functions will only return the
+    first value when multiple values for one key are found.

+    exceptions.

+"""Implements a number of Python exceptions which can be raised from within
+a view to trigger a standard HTTP non-200 response.
+
+Usage Example
+-------------
+
+.. code-block:: python
+
+    from werkzeug.wrappers.request import Request
+    from werkzeug.exceptions import HTTPException, NotFound
+
+    def view(request):
+        raise NotFound()
+
+    @Request.application
+    def application(request):
+        try:
+            return view(request)
+        except HTTPException as e:
+            return e
+
+As you can see from this example those exceptions are callable WSGI
+applications. However, they are not Werkzeug response objects. You
+can get a response object by calling ``get_response()`` on a HTTP
+exception.
+
+Keep in mind that you may have to pass an environ (WSGI) or scope
+(ASGI) to ``get_response()`` because some errors fetch additional
+information relating to the request.
+
+If you want to hook in a different exception page to say, a 404 status
+code, you can add a second except for a specific subclass of an error:
+
+.. code-block:: python
+
+    @Request.application
+    def application(request):
+        try:
+            return view(request)
+        except NotFound as e:
+            return not_found(request)
+        except HTTPException as e:
+            return e

+Application Dispatcher
+======================
+
+This middleware creates a single WSGI application that dispatches to
+multiple other WSGI applications mounted at different URL paths.
+
+A common example is writing a Single Page Application, where you have a
+backend API and a frontend written in JavaScript that does the routing
+in the browser rather than requesting different pages from the server.
+The frontend is a single HTML and JS file that should be served for any
+path besides "/api".
+
+This example dispatches to an API app under "/api", an admin app
+under "/admin", and an app that serves frontend files for all other
+requests::
+
+    app = DispatcherMiddleware(serve_frontend, {
+        '/api': api_app,
+        '/admin': admin_app,
+    })
+
+In production, you might instead handle this at the HTTP server level,
+serving files or proxying to application servers based on location. The
+API and admin apps would each be deployed with a separate WSGI server,
+and the static files would be served directly by the HTTP server.

+    """Proxy requests under a path to an external server, routing other
+    requests to the app.
+
+    This middleware can only proxy HTTP requests, as HTTP is the only
+    protocol handled by the WSGI server. Other protocols, such as
+    WebSocket requests, cannot be proxied at this layer. This should
+    only be used for development, in production a real proxy server
+    should be used.
+
+    The middleware takes a dict mapping a path prefix to a dict
+    describing the host to be proxied to::
+
+        app = ProxyMiddleware(app, {
+            "/static/": {
+                "target": "http://127.0.0.1:5001/",
+            }
+        })
+
+    Each host has the following options:
+
+    ``target``:
+        The target URL to dispatch to. This is required.
+    ``remove_prefix``:
+        Whether to remove the prefix from the URL before dispatching it
+        to the target. The default is ``False``.
+    ``host``:
+        ``"<auto>"`` (default):
+            The host header is automatically rewritten to the URL of the
+            target.
+        ``None``:
+            The host header is unmodified from the client request.
+        Any other value:
+            The host header is overwritten with the value.
+    ``headers``:
+        A dictionary of headers to be sent with the request to the
+        target. The default is ``{}``.
+    ``ssl_context``:
+        A :class:`ssl.SSLContext` defining how to verify requests if the
+        target is HTTPS. The default is ``None``.
+
+    In the example above, everything under ``"/static/"`` is proxied to
+    the server on port 5001. The host header is rewritten to the target,
+    and the ``"/static/"`` prefix is removed from the URLs.
+
+    :param app: The WSGI application to wrap.
+    :param targets: Proxy target configurations. See description above.
+    :param chunk_size: Size of chunks to read from input stream and
+        write to target.
+    :param timeout: Seconds before an operation to a target fails.

+X-Forwarded-For Proxy Fix
+=========================
+
+This module provides a middleware that adjusts the WSGI environ based on
+``X-Forwarded-`` headers that proxies in front of an application may
+set.
+
+When an application is running behind a proxy server, WSGI may see the
+request as coming from that server rather than the real client. Proxies
+set various headers to track where the request actually came from.
+
+This middleware should only be used if the application is actually
+behind such a proxy, and should be configured with the number of proxies
+that are chained in front of it. Not all proxies set all the headers.
+Since incoming headers can be faked, you must set how many proxies are
+setting each header so the middleware knows what to trust.

+    """A WSGI middleware which provides static content for development
+    environments or simple server setups. Its usage is quite simple::
+
+        import os
+        from werkzeug.middleware.shared_data import SharedDataMiddleware
+
+        app = SharedDataMiddleware(app, {
+            '/shared': os.path.join(os.path.dirname(__file__), 'shared')
+        })
+
+    The contents of the folder ``./shared`` will now be available on
+    ``http://example.com/shared/``.  This is pretty useful during development
+    because a standalone media server is not required. Files can also be
+    mounted on the root folder and still continue to use the application because
+    the shared data middleware forwards all unhandled requests to the
+    application, even if the requests are below one of the shared folders.
+
+    If `pkg_resources` is available you can also tell the middleware to serve
+    files from package data::
+
+        app = SharedDataMiddleware(app, {
+            '/static': ('myapplication', 'static')
+        })
+
+    This will then serve the ``static`` folder in the `myapplication`
+    Python package.
+
+    The optional `disallow` parameter can be a list of :func:`~fnmatch.fnmatch`
+    rules for files that are not accessible from the web.  If `cache` is set to
+    `False` no caching headers are sent.
+
+    Currently the middleware does not support non-ASCII filenames. If the
+    encoding on the file system happens to match the encoding of the URI it may
+    work but this could also be by accident. We strongly suggest using ASCII
+    only file names for static files.
+
+    The middleware will guess the mimetype using the Python `mimetype`
+    module.  If it's unable to figure out the charset it will fall back
+    to `fallback_mimetype`.
+
+    :param app: the application to wrap.  If you don't want to wrap an
+                application you can pass it :exc:`NotFound`.
+    :param exports: a list or dict of exported files and folders.
+    :param disallow: a list of :func:`~fnmatch.fnmatch` rules.
+    :param cache: enable or disable caching headers.
+    :param cache_timeout: the cache timeout in seconds for the headers.
+    :param fallback_mimetype: The fallback mimetype for unknown files.
+
+    .. versionchanged:: 1.0
+        The default ``fallback_mimetype`` is

+"""When it comes to combining multiple controller or view functions
+(however you want to call them) you need a dispatcher. A simple way
+would be applying regular expression tests on the ``PATH_INFO`` and
+calling registered callback functions that return the value then.
+
+This module implements a much more powerful system than simple regular
+expression matching because it can also convert values in the URLs and
+build URLs.
+
+Here a simple example that creates a URL map for an application with
+two subdomains (www and kb) and some URL rules:
+
+.. code-block:: python
+
+    m = Map([
+        # Static URLs
+        Rule('/', endpoint='static/index'),
+        Rule('/about', endpoint='static/about'),
+        Rule('/help', endpoint='static/help'),
+        # Knowledge Base
+        Subdomain('kb', [
+            Rule('/', endpoint='kb/index'),
+            Rule('/browse/', endpoint='kb/browse'),
+            Rule('/browse/<int:id>/', endpoint='kb/browse'),
+            Rule('/browse/<int:id>/<int:page>', endpoint='kb/browse')
+        ])
+    ], default_subdomain='www')
+
+If the application doesn't use subdomains it's perfectly fine to not set
+the default subdomain and not use the `Subdomain` rule factory. The
+endpoint in the rules can be anything, for example import paths or
+unique identifiers. The WSGI application can use those endpoints to get the
+handler for that URL.  It doesn't have to be a string at all but it's
+recommended.
+
+Now it's possible to create a URL adapter for one of the subdomains and
+build URLs:
+
+.. code-block:: python
+
+    c = m.bind('example.com')
+
+    c.build("kb/browse", dict(id=42))
+    'http://kb.example.com/browse/42/'
+
+    c.build("kb/browse", dict())
+    'http://kb.example.com/browse/'
+
+    c.build("kb/browse", dict(id=42, page=3))
+    'http://kb.example.com/browse/42/3'
+
+    c.build("static/about")
+    '/about'
+
+    c.build("static/index", force_external=True)
+    'http://www.example.com/'
+
+    c = m.bind('example.com', subdomain='kb')
+
+    c.build("static/about")
+    'http://www.example.com/about'
+
+The first argument to bind is the server name *without* the subdomain.
+Per default it will assume that the script is mounted on the root, but
+often that's not the case so you can provide the real mount point as
+second argument:
+
+.. code-block:: python
+
+    c = m.bind('example.com', '/applications/example')
+
+The third argument can be the subdomain, if not given the default
+subdomain is used.  For more details about binding have a look at the
+documentation of the `MapAdapter`.
+
+And here is how you can match URLs:
+
+.. code-block:: python
+
+    c = m.bind('example.com')
+
+    c.match("/")
+    ('static/index', {})
+
+    c.match("/about")
+    ('static/about', {})
+
+    c = m.bind('example.com', '/', 'kb')
+
+    c.match("/")
+    ('kb/index', {})
+
+    c.match("/browse/42/23")
+    ('kb/browse', {'id': 42, 'page': 23})
+
+If matching fails you get a ``NotFound`` exception, if the rule thinks
+it's a good idea to redirect (for example because the URL was defined
+to have a slash at the end but the request was missing that slash) it
+will raise a ``RequestRedirect`` exception. Both are subclasses of
+``HTTPException`` so you can use those errors as responses in the

+        """The usage is simple: you just pass the match method the current
+        path info as well as the method (which defaults to `GET`).  The
+        following things can then happen:
+
+        - you receive a `NotFound` exception that indicates that no URL is
+          matching.  A `NotFound` exception is also a WSGI application you
+          can call to get a default page not found page (happens to be the
+          same object as `werkzeug.exceptions.NotFound`)
+
+        - you receive a `MethodNotAllowed` exception that indicates that there
+          is a match for this URL but not for the current request method.
+          This is useful for RESTful applications.
+
+        - you receive a `RequestRedirect` exception with a `new_url`
+          attribute.  This exception is used to notify you about a request
+          Werkzeug requests from your WSGI application.  This is for example the
+          case if you request ``/foo`` although the correct URL is ``/foo/``
+          You can use the `RequestRedirect` instance as response-like object
+          similar to all other subclasses of `HTTPException`.
+
+        - you receive a ``WebsocketMismatch`` exception if the only
+          match is a WebSocket rule but the bind is an HTTP request, or
+          if the match is an HTTP rule but the bind is a WebSocket
+          request.
+
+        - you get a tuple in the form ``(endpoint, arguments)`` if there is
+          a match (unless `return_rule` is True, in which case you get a tuple
+          in the form ``(rule, arguments)``)
+
+        If the path info is not passed to the match method the default path
+        info of the map is used (defaults to the root URL if not defined
+        explicitly).
+
+        All of the exceptions raised are subclasses of `HTTPException` so they
+        can be used as WSGI responses. They will all render generic error or
+        redirect pages.
+
+        Here is a small example for matching:
+
+        >>> m = Map([
+        ...     Rule('/', endpoint='index'),
+        ...     Rule('/downloads/', endpoint='downloads/index'),

+        ... ])
+        >>> urls = m.bind("example.com", "/")

+        ('index', {})
+        >>> urls.match("/downloads/42")
+        ('downloads/show', {'id': 42})
+
+        And here is what happens on redirect and missing URLs:
+
+        >>> urls.match("/downloads")
+        Traceback (most recent call last):
+          ...
+        RequestRedirect: http://example.com/downloads/

+    """A Rule represents one URL pattern.  There are some options for `Rule`
+    that change the way it behaves and are passed to the `Rule` constructor.
+    Note that besides the rule-string all arguments *must* be keyword arguments
+    in order to not break the application on Werkzeug upgrades.
+
+    `string`
+        Rule strings basically are just normal URL paths with placeholders in
+        the format ``<converter(arguments):name>`` where the converter and the
+        arguments are optional.  If no converter is defined the `default`
+        converter is used which means `string` in the normal configuration.
+
+        URL rules that end with a slash are branch URLs, others are leaves.
+        If you have `strict_slashes` enabled (which is the default), all
+        branch URLs that are matched without a trailing slash will trigger a
+        redirect to the same URL with the missing slash appended.
+
+        The converters are defined on the `Map`.
+
+    `endpoint`
+        The endpoint for this rule. This can be anything. A reference to a
+        function, a string, a number etc.  The preferred way is using a string
+        because the endpoint is used for URL generation.
+
+    `defaults`
+        An optional dict with defaults for other rules with the same endpoint.
+        This is a bit tricky but useful if you want to have unique URLs::
+
+            url_map = Map([
+                Rule('/all/', defaults={'page': 1}, endpoint='all_entries'),
+                Rule('/all/page/<int:page>', endpoint='all_entries')
+            ])
+
+        If a user now visits ``http://example.com/all/page/1`` they will be
+        redirected to ``http://example.com/all/``.  If `redirect_defaults` is
+        disabled on the `Map` instance this will only affect the URL
+        generation.
+
+    `subdomain`
+        The subdomain rule string for this rule. If not specified the rule
+        only matches for the `default_subdomain` of the map.  If the map is
+        not bound to a subdomain this feature is disabled.
+
+        Can be useful if you want to have user profiles on different subdomains
+        and all subdomains are forwarded to your application::
+
+            url_map = Map([
+                Rule('/', subdomain='<username>', endpoint='user/homepage'),
+                Rule('/stats', subdomain='<username>', endpoint='user/stats')
+            ])
+
+    `methods`
+        A sequence of http methods this rule applies to.  If not specified, all
+        methods are allowed. For example this can be useful if you want different
+        endpoints for `POST` and `GET`.  If methods are defined and the path
+        matches but the method matched against is not in this list or in the
+        list of another rule for that path the error raised is of the type
+        `MethodNotAllowed` rather than `NotFound`.  If `GET` is present in the
+        list of methods and `HEAD` is not, `HEAD` is added automatically.
+
+    `strict_slashes`
+        Override the `Map` setting for `strict_slashes` only for this rule. If
+        not specified the `Map` setting is used.
+
+    `merge_slashes`
+        Override :attr:`Map.merge_slashes` for this rule.
+
+    `build_only`
+        Set this to True and the rule will never match but will create a URL
+        that can be build. This is useful if you have resources on a subdomain
+        or folder that are not handled by the WSGI application (like static data)
+
+    `redirect_to`
+        If given this must be either a string or callable.  In case of a
+        callable it's called with the url adapter that triggered the match and
+        the values of the URL as keyword arguments and has to return the target
+        for the redirect, otherwise it has to be a string with placeholders in
+        rule syntax::
+
+            def foo_with_slug(adapter, id):
+                # ask the database for the slug for the old id.  this of
+                # course has nothing to do with werkzeug.
+                return f'foo/{Foo.get_slug_for_id(id)}'
+
+            url_map = Map([
+                Rule('/foo/<slug>', endpoint='foo'),
+                Rule('/some/old/url/<slug>', redirect_to='foo/<slug>'),
+                Rule('/other/old/url/<int:id>', redirect_to=foo_with_slug)
+            ])
+
+        When the rule is matched the routing system will raise a
+        `RequestRedirect` exception with the target for the redirect.
+
+        Keep in mind that the URL will be joined against the URL root of the
+        script so don't use a leading slash on the target URL unless you
+        really mean root of that domain.
+
+    `alias`
+        If enabled this rule serves as an alias for another rule with the same
+        endpoint and arguments.
+
+    `host`
+        If provided and the URL map has host matching enabled this can be
+        used to provide a match rule for the whole host.  This also means
+        that the subdomain feature is disabled.
+
+    `websocket`
+        If ``True``, this rule is only matches for WebSocket (``ws://``,
+        ``wss://``) requests. By default, rules will only match for HTTP
+        requests.
+

+        Can be a domain, IPv4 or IPv6 address, or file path starting
+        with ``unix://`` for a Unix socket.
+    :param port: The port to bind to, for example ``8080``. Using ``0``
+        tells the OS to pick a random free port.
+    :param application: The WSGI application to run.
+    :param use_reloader: Use a reloader process to restart the server
+        process when files are changed.
+    :param use_debugger: Use Werkzeug's debugger, which will show
+        formatted tracebacks on unhandled exceptions.

+        can be opened for any frame in the traceback. Some protection is

+        on a publicly visible server.
+    :param extra_files: The reloader will watch these files for changes
+        in addition to Python modules. For example, watch a
+        configuration file.
+    :param exclude_patterns: The reloader will ignore changes to any
+        files matching these :mod:`fnmatch` patterns. For example,
+        ignore cache files.
+    :param reloader_interval: How often the reloader tries to check for
+        changes.
+    :param reloader_type: The reloader to use. The ``'stat'`` reloader
+        is built in, but may require significant CPU to watch files. The
+        ``'watchdog'`` reloader is much more efficient but requires
+        installing the ``watchdog`` package first.

+    :param processes: Handle concurrent requests using up to this number
+        of processes. Cannot be used with ``threaded``.
+    :param request_handler: Use a different
+        :class:`~BaseHTTPServer.BaseHTTPRequestHandler` subclass to
+        handle requests.
+    :param static_files: A dict mapping URL prefixes to directories to
+        serve static files from using
+        :class:`~werkzeug.middleware.SharedDataMiddleware`.
+    :param passthrough_errors: Don't catch unhandled exceptions at the
+        server level, let the server crash instead. If ``use_debugger``
+        is enabled, the debugger will still catch such errors.
+    :param ssl_context: Configure TLS to serve over HTTPS. Can be an
+        :class:`ssl.SSLContext` object, a ``(cert_file, key_file)``
+        tuple to create a typical context, or the string ``'adhoc'`` to
+        generate a temporary self-signed certificate.

+
+    The signature of this class is also used in some other places as of
+    Werkzeug 0.5 (:func:`create_environ`, :meth:`Response.from_values`,
+    :meth:`Client.open`).  Because of this most of the functionality is
+    available through the constructor alone.

+    other with the :attr:`form` and :attr:`files` attributes, but are
+    passed with the same argument to the constructor: `data`.
+
+    `data` can be any of these values:
+
+    -   a `str` or `bytes` object: The object is converted into an
+        :attr:`input_stream`, the :attr:`content_length` is set and you have to
+        provide a :attr:`content_type`.
+    -   a `dict` or :class:`MultiDict`: The keys have to be strings. The values
+        have to be either any of the following objects, or a list of any of the
+        following objects:
+
+        -   a :class:`file`-like object:  These are converted into
+            :class:`FileStorage` objects automatically.
+        -   a `tuple`:  The :meth:`~FileMultiDict.add_file` method is called
+            with the key and the unpacked `tuple` items as positional
+            arguments.
+        -   a `str`:  The string is set as form data for the associated key.
+    -   a file-like object: The object content is loaded in memory and then
+        handled like a regular `str` or a `bytes`.
+
+    :param path: the path of the request.  In the WSGI environment this will
+                 end up as `PATH_INFO`.  If the `query_string` is not defined

+                 it is used as query string.
+    :param base_url: the base URL is a URL that is used to extract the WSGI
+                     URL scheme, host (server name + server port) and the
+                     script root (`SCRIPT_NAME`).
+    :param query_string: an optional string or dict with URL parameters.
+    :param method: the HTTP method to use, defaults to `GET`.
+    :param input_stream: an optional input stream.  Do not specify this and
+                         `data`.  As soon as an input stream is set you can't
+                         modify :attr:`args` and :attr:`files` unless you
+                         set the :attr:`input_stream` to `None` again.
+    :param content_type: The content type for the request.  As of 0.5 you

+
+    The first argument can be a file path or a file-like object. Paths
+    are preferred in most cases because Werkzeug can manage the file and
+    get extra information from the path. Passing a file-like object
+    requires that the file is opened in binary mode, and is mostly
+    useful when building a file in memory with :class:`io.BytesIO`.
+
+    Never pass file paths provided by a user. The path is assumed to be
+    trusted, so a user could craft a path to access a file you didn't
+    intend. Use :func:`send_from_directory` to safely serve user-provided paths.
+
+    If the WSGI server sets a ``file_wrapper`` in ``environ``, it is
+    used, otherwise Werkzeug's built-in wrapper is used. Alternatively,
+    if the HTTP server supports ``X-Sendfile``, ``use_x_sendfile=True``
+    will tell the server to send the given path, which is much more
+    efficient than reading it in Python.
+
+    :param path_or_file: The path to the file to send, relative to the
+        current working directory if a relative path is given.
+        Alternatively, a file-like object opened in binary mode. Make
+        sure the file pointer is seeked to the start of the data.
+    :param environ: The WSGI environ for the current request.
+    :param mimetype: The MIME type to send for the file. If not
+        provided, it will try to detect it from the file name.
+    :param as_attachment: Indicate to a browser that it should offer to
+        save the file instead of displaying it.
+    :param download_name: The default name browsers will use when saving
+        the file. Defaults to the passed file name.
+    :param conditional: Enable conditional and range responses based on
+        request headers. Requires passing a file path and ``environ``.
+    :param etag: Calculate an ETag for the file, which requires passing
+        a file path. Can also be a string to use instead.
+    :param last_modified: The last modified time to send for the file,
+        in seconds. If not provided, it will try to detect it from the
+        file path.
+    :param max_age: How long the client should cache the file, in
+        seconds. If set, ``Cache-Control`` will be ``public``, otherwise
+        it will be ``no-cache`` to prefer conditional caching.
+    :param use_x_sendfile: Set the ``X-Sendfile`` header to let the
+        server to efficiently send the file. Requires support from the
+        HTTP server. Requires passing a file path.
+    :param response_class: Build the response using this class. Defaults
+        to :class:`~werkzeug.wrappers.Response`.
+    :param _root_path: Do not use. For internal use only. Use
+        :func:`send_from_directory` to safely send files under a path.

+
+    The response body is flexible to support different use cases. The
+    simple form is passing bytes, or a string which will be encoded as
+    UTF-8. Passing an iterable of bytes or strings makes this a
+    streaming response. A generator is particularly useful for building
+    a CSV file in memory or using SSE (Server Sent Events). A file-like
+    object is also iterable, although the
+    :func:`~werkzeug.utils.send_file` helper should be used in that
+    case.
+
+    The response object is itself a WSGI application callable. When
+    called (:meth:`__call__`) with ``environ`` and ``start_response``,
+    it will pass its status and headers to ``start_response`` then
+    return its body as an iterable.
