-<#
-.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: 
-https://go.microsoft.com/fwlink/?LinkID=135170

-.Description
-Get-PyVenvConfig parses the values from the pyvenv.cfg file located in the
-given folder, and returns them in a map.
-
-For each line in the pyvenv.cfg file, if that line can be parsed into exactly
-two strings separated by `=` (with any amount of whitespace surrounding the =)
-then it is considered a `key = value` line. The left hand string is the key,
-the right hand is the value.
-
-If the value starts with a `'` or a `"` then the first and last character is
-stripped from the value before being captured.
-
-.Parameter ConfigDir
-Path to the directory that contains the `pyvenv.cfg` file.

-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.

-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.

-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.
-
-
-Installing
-----------
-
-Install and update using `pip`_:
-
-.. code-block:: text
-
-    pip install -U MarkupSafe
-
-.. _pip: https://pip.pypa.io/en/stable/quickstart/
-
-
-Examples
---------
-
-.. code-block:: 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>')

-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.
-

-Installing
-----------
-
-Install and update using `pip`_:
-
-.. code-block:: text
-
-    pip install -U Werkzeug
-
-.. _pip: https://pip.pypa.io/en/stable/quickstart/

-
-.. code-block:: python
-
-    from werkzeug.wrappers import Request, Response
-
-    @Request.application
-    def application(request):
-        return Response('Hello, World!')
-
-    if __name__ == '__main__':
-        from werkzeug.serving import run_simple

-==========
-
-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
-
-
-Installing
-----------
-
-Install and update using `pip`_:
-
-.. code-block:: text
-
-    $ pip install -U click
-
-.. _pip: https://pip.pypa.io/en/stable/quickstart/
-
-
-A Simple Example
-----------------
-
-.. code-block:: 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()
-
-.. code-block:: text
-
-    $ python hello.py --count=3

-

-                      command.  For the toplevel script it is usually

-                               from environment variables is disabled.  This
-                               does not affect manually set environment
-                               variables which are always read.
-    :param default_map: a dictionary (like object) with default values

-    :param terminal_width: the width of the terminal.  The default is
-                           inherit from parent context.  If no context

-                              pages).  This defaults to 80 characters if

-                              terminal is larger than that, Click will not
-                              format things wider than 80 characters by

-                             kept on the context.  The default is to inherit
-                             from the command.

-                                   not know and keeps them for later
-                                   processing.

-                              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

-    :class:`Option`\s or :class:`Argument`\s.  Other subclasses are currently
-    not supported by design as some of the internals for parsing are
-    intentionally not finalized.
-
-    Some settings are supported by both options and arguments.
-
-    :param param_decls: the parameter declarations for this option or
-                        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 later is converted into the former
-                 automatically if supported.
-    :param required: controls if this is optional or not.
-    :param default: the default value if omitted.  This can also be a callable,
-                    in which case it's invoked when the default is needed
-                    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
-        strings.
-
-    .. 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.
-
-    .. versionchanged:: 8.0
-        ``autocompletion`` is renamed to ``shell_complete`` and has new
-        semantics described above. The old name is deprecated and will
-        be removed in 8.1, until then it will be wrapped to match the
-        new requirements.
-
-    .. versionchanged:: 8.0
-        For ``multiple=True, nargs>1``, the default must be a list of
-        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
-        empty string value. This makes it possible for scripts to clear
-        variables if they can't unset them.
-
-    .. versionchanged:: 2.0
-        Changed signature for parameter callback to also be passed the
-        parameter. The old callback format will still work, but it will
-        raise a warning to give you a chance to migrate the code easier.

-"""
-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 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.

-                      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.

-class Flask(Scaffold):
-    """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.

-
-    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::
-
-        app.config.from_envvar('YOURAPPLICATION_SETTINGS')

-    is converted into a response object by Flask itself, it becomes tricky to
-    add headers to it.  This function can be called instead of using a return
-    and you will get a response object which you can use to attach headers.
-
-    If view looked like this and you want to add a new header::
-
-        def index():
-            return render_template('index.html', foo=42)

-    code::
-
-        response = make_response(render_template('not_found.html'), 404)
-
-    The other use case of this function is to force the return value of a

-    decorators::

-    `url_for` (instead of `url_for`'s default to raise the

-    An example::
-
-        def external_url_handler(error, endpoint, values):
-            "Looks up an external URL when `url_for` cannot build a URL."
-            # This is an example of hooking the build_error_handler.

-to handle this we will dump the items as a list of ``[key, value]``
-pairs. Subclass :class:`JSONTag` and give it the new key ``' od'`` to
-identify the type. The session serializer processes dicts first, so
-insert the new tag at the front of the order since ``OrderedDict`` must
-be processed before ``dict``.

-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.
-
-
-Installing
-----------
-
-Install and update using `pip`_:
-
-.. code-block:: text
-
-    pip install -U itsdangerous
-
-.. _pip: https://pip.pypa.io/en/stable/quickstart/
-
-
-A Simple Example
-----------------
-
-Here's how you could generate a token for transmitting a user's id and
-name between web requests.
-
-.. code-block:: 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

-    the minimal interface required.
-
-    Libraries compatible with this class:
-
-    -   `cachelib <https://github.com/pallets/cachelib>`_
-    -   `python-memcached <https://pypi.org/project/python-memcached/>`_

-    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.

-    they are not shared and if no template was loaded so far.
-    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.

-    If you don't want that behavior set the `babel_style` parameter to `False`
-    which causes only strings to be returned and parameters are always stored
-    in tuples.  As a consequence invalid gettext calls (calls without a single
-    string parameter or string parameters after non-string parameters) are
-    skipped.
-
-    This example explains the behavior:

-
-    * ``lineno`` is the number of the line on which the string was found,
-    * ``function`` is the name of the ``gettext`` function used (if the
-      string was extracted from embedded Python code), and
-    *   ``message`` is the string, or a tuple of strings for functions
-         with multiple string arguments.
-
-    This extraction function operates on the AST and is because of that unable
-    to extract any comments.  For comment support you have to use the babel

-between parses. pip parses general options twice internally, and shouldn't
-pass on state. To be consistent, all options will follow this design.

-    # Special case pip and setuptools to generate versioned wrappers

-    # The issue is that some projects (specifically, pip and setuptools) use
-    # code in setup.py to create "versioned" entry points - pip2.7 on Python
-    # 2.7, pip3.3 on Python 3.3, etc. But these entry points are baked into
-    # the wheel metadata at build time, and so if the wheel is installed with
-    # 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
-    # incorrect versioned entry points, or they will not be able to distribute
-    # "universal" wheels (i.e., they will need a wheel per Python version).
-    #
-    # Because setuptools and pip are bundled with _ensurepip and virtualenv,
-    # we need to use universal wheels. So, as a stopgap until Metadata 2.0, we
-    # override the versioned entry points in the wheel and generate the
-    # correct ones. This code is purely a short-term measure until Metadata 2.0
-    # is available.
-    #
-    # To add the level of hack in this section of code, in order to support
-    # ensurepip this code will look for an ``ENSUREPIP_OPTIONS`` environment
-    # variable which will control which version scripts get installed.
-    #

-"""For neatly implementing static typing in pip.
-
-`mypy` - the static type analysis tool we use - uses the `typing` module, which
-provides core functionality fundamental to mypy's functioning.
-
-Generally, `typing` would be imported at runtime and used in that fashion -
-it acts as a no-op at runtime and does not have any run-time overhead by
-design.
-
-As it turns out, `typing` is not vendorable - it uses separate sources for
-Python 2/Python 3. Thus, this codebase can not expect it to be present.
-To work around this, mypy allows the typing import to be behind a False-y
-optional to prevent it from running at runtime and type-comments can be used
-to remove the need for the types to be accessible directly during runtime.
-
-This module provides the False-y guard in a nicely named fashion so that a
-curious maintainer can reach here to read this.
-
-In pip, all static-typing related imports should be guarded as follows:
-
-    from pip._internal.utils.typing import MYPY_CHECK_RUNNING
-
-    if MYPY_CHECK_RUNNING:
-        from typing import ...
-
-Ref: https://github.com/python/mypy/issues/3216

-if MYPY_CHECK_RUNNING:
-    from typing import cast
-else:
-    # typing's cast() is needed at runtime, but we don't want to import typing.
-    # Thus, we use a dummy no-op version, which we tell mypy to ignore.
-    def cast(type_, value):  # type: ignore
-        return value

-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
- - 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

-           Repeated parse attempts at the same string location (which happens
-           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.

-class Word(Token):
-    """
-    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::
-        # 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+'-')

-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

-           Repeated parse attempts at the same string location (which happens
-           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 
-    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.)

-    Helper method for constructing grammars of expressions made up of
-    operators working in a precedence hierarchy.  Operators may be unary or
-    binary, left- or right-associative.  Parse actions can also be attached
-    to operator expressions. The generated parser will also recognize the use 
-    of parentheses to override operator precedences (see example below).
-    
-    Note: if you define a deep operator list, you may see performance issues
-    when using infixNotation. See L{ParserElement.enablePackrat} for a
-    mechanism to potentially improve your parser performance.
-
-    Parameters:
-     - baseExpr - expression representing the most basic element for the nested
-     - opList - list of tuples, one for each operator precedence level in the
-      expression grammar; each tuple is of the form
-      (opExpr, numTerms, rightLeftAssoc, parseAction), where:
-       - opExpr is the pyparsing expression for the operator;
-          may also be a string, which will be converted to a Literal;
-          if numTerms is 3, opExpr is a tuple of two expressions, for the
-          two operators separating the 3 terms
-       - numTerms is the number of terms for this operator (must
-          be 1, 2, or 3)
-       - rightLeftAssoc is the indicator whether the operator is
-          right or left associative, using the pyparsing-defined
-          constants C{opAssoc.RIGHT} and C{opAssoc.LEFT}.
-       - 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
-          is passed a tuple or list of functions, this is equivalent to
-          calling C{setParseAction(*fn)} (L{ParserElement.setParseAction})
-     - lpar - expression for matching left-parentheses (default=C{Suppress('(')})

-"""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.

-        bad install directory or PYTHONPATH
-
-        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.readthedocs.io/en/latest/easy_install.html#custom-installation-locations

-    importing data from the original distribution. Any such finders need to be
-    cleared since the replacement distribution might be packaged differently,
-    e.g. a zipped egg distribution might get replaced with an unzipped egg
-    folder or vice versa. Having the old finders cached may then cause Python
-    to attempt loading modules from the replacement distribution using an
-    incorrect loader.
-
-    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
-    information. Such an operation may then fail outright, e.g. report having
-    read a 'bad local file header', or even worse, it may fail silently &
-    return invalid data.
-
-    zipimport._zip_directory_cache contains cached zip archive directory
-    information for all existing zipimport.zipimporter instances and all such
-    instances connected to the same archive share the same cached directory
-    information.

-    If asked, and the underlying Python implementation allows it, we can fix
-    all existing zipimport.zipimporter instances instead of having to track
-    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
-    distribution and thus cause such load operations to fail. Note that when
-    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

-class Distribution(_Distribution):
-    """Distribution with support for features, 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.
-
-     'features' **deprecated** -- a dictionary mapping option names to
-        'setuptools.Feature'
-        objects.  Features are a portion of the distribution that can be
-        included or excluded based on user options, inter-feature dependencies,
-        and availability on the current system.  Excluded features are omitted
-        from all setup commands, including source and binary distributions, so
-        you can create multiple distributions from the same source tree.
-        Feature names should be valid Python identifiers, except that they may
-        contain the '-' (minus) sign.  Features can be included or excluded
-        via the command line options '--with-X' and '--without-X', where 'X' is
-        the name of the feature.  Whether a feature is included by default, and
-        whether you are allowed to control this from the command line, is
-        determined by the Feature object.  See the 'Feature' class for more
-        information.
-
-     '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.  They are used by the feature subsystem to configure the
-    distribution for the included and excluded features.

-
-    A subset of the distribution that can be excluded if unneeded/wanted
-
-    Features are created using these keyword arguments:
-
-      'description' -- a short, human readable description of the feature, to
-         be used in error messages, and option help messages.
-
-      'standard' -- if true, the feature is included by default if it is
-         available on the current system.  Otherwise, the feature is only
-         included if requested via a command line '--with-X' option, or if
-         another included feature requires it.  The default setting is 'False'.
-
-      'available' -- if true, the feature is available for installation on the
-         current system.  The default setting is 'True'.
-
-      'optional' -- if true, the feature's inclusion can be controlled from the
-         command line, using the '--with-X' or '--without-X' options.  If
-         false, the feature's inclusion status is determined automatically,
-         based on 'availabile', 'standard', and whether any other feature
-         requires it.  The default setting is 'True'.
-
-      'require_features' -- a string or sequence of strings naming features
-         that should also be included if this feature is included.  Defaults to
-         empty list.  May also contain 'Require' objects that should be
-         added/removed from the distribution.
-
-      'remove' -- a string or list of strings naming packages to be removed
-         from the distribution if this feature is *not* included.  If the
-         feature *is* included, this argument is ignored.  This argument exists
-         to support removing features that "crosscut" a distribution, such as
-         defining a 'tests' feature that removes all the 'tests' subpackages
-         provided by other features.  The default for this argument is an empty
-         list.  (Note: the named package(s) or modules must exist in the base
-         distribution when the 'setup()' function is initially called.)
-
-      other keywords -- any other keyword arguments are saved, and passed to
-         the distribution's 'include()' and 'exclude()' methods when the
-         feature is included or excluded, respectively.  So, for example, you
-         could pass 'packages=["a","b"]' to cause packages 'a' and 'b' to be
-         added or removed from the distribution as appropriate.
-
-    A feature must include at least one 'requires', 'remove', or other
-    keyword argument.  Otherwise, it can't affect the distribution in any way.
-    Note also that you can subclass 'Feature' to create your own specialized
-    feature types that modify the distribution in other ways when included or
-    excluded.  See the docstrings for the various methods here for more detail.
-    Aside from the methods, the only feature attributes that distributions look
-    at are 'description' and 'optional'.

-class Headers:
-    """An object that stores some headers. It has a dict-like interface,
-    but is ordered, can store the same key multiple times, and iterating
-    yields ``(key, value)`` pairs instead of only keys.
-
-    This data structure is useful if you want a nicer way to handle WSGI
-    headers which are stored as tuples in a list.
-
-    From Werkzeug 0.3 onwards, the :exc:`KeyError` raised by this class is
-    also a subclass of the :class:`~exceptions.BadRequest` HTTP exception
-    and will render a page for a ``400 BAD REQUEST`` if caught in a
-    catch-all for HTTP exceptions.
-
-    Headers is mostly compatible with the Python :class:`wsgiref.headers.Headers`
-    class, with the exception of `__getitem__`.  :mod:`wsgiref` will return
-    `None` for ``headers['missing']``, whereas :class:`Headers` will raise
-    a :class:`KeyError`.
-
-    To create a new :class:`Headers` object pass it a list or dict of headers
-    which are used as default values.  This does not reuse the list passed
-    to the constructor for internal usage.
-
-    :param defaults: The list of default values for the :class:`Headers`.
-
-    .. versionchanged:: 0.9
-       This data structure now stores unicode values similar to how the
-       multi dicts do it.  The main difference is that bytes can be set as
-       well which will automatically be latin1 decoded.
-
-    .. versionchanged:: 0.9
-       The :meth:`linked` function was removed without replacement as it
-       was an API that does not support the changes to the encoding model.

-UBUNTU FONT LICENCE Version 1.0
--------------------------------
-
-PREAMBLE
-This licence allows the licensed fonts to be used, studied, modified and
-redistributed freely. The fonts, including any derivative works, can be
-bundled, embedded, and redistributed provided the terms of this licence
-are met. The fonts and derivatives, however, cannot be released under
-any other licence. The requirement for fonts to remain under this
-licence does not require any document created using the fonts or their
-derivatives to be published under this licence, as long as the primary
-purpose of the document is not to be a vehicle for the distribution of
-the fonts.
-
-DEFINITIONS
-"Font Software" refers to the set of files released by the Copyright
-Holder(s) under this licence and clearly marked as such. This may
-include source files, build scripts and documentation.
-
-"Original Version" refers to the collection of Font Software components
-as received under this licence.
-
-"Modified Version" refers to any derivative made by adding to, deleting,
-or substituting -- in part or in whole -- any of the components of the
-Original Version, by changing formats or by porting the Font Software to
-a new environment.
-
-"Copyright Holder(s)" refers to all individuals and companies who have a
-copyright ownership of the Font Software.
-
-"Substantially Changed" refers to Modified Versions which can be easily
-identified as dissimilar to the Font Software by users of the Font
-Software comparing the Original Version with the Modified Version.
-
-To "Propagate" a work means to do anything with it that, without
-permission, would make you directly or secondarily liable for
-infringement under applicable copyright law, except executing it on a
-computer or modifying a private copy. Propagation includes copying,
-distribution (with or without modification and with or without charging
-a redistribution fee), making available to the public, and in some
-countries other activities as well.
-
-PERMISSION & CONDITIONS
-This licence does not grant any rights under trademark law and all such
-rights are reserved.
-
-Permission is hereby granted, free of charge, to any person obtaining a
-copy of the Font Software, to propagate the Font Software, subject to
-the below conditions:
-
-1) Each copy of the Font Software must contain the above copyright
-notice and this licence. These can be included either as stand-alone
-text files, human-readable headers or in the appropriate machine-
-readable metadata fields within text or binary files as long as those
-fields can be easily viewed by the user.
-
-2) The font name complies with the following:
-(a) The Original Version must retain its name, unmodified.
-(b) Modified Versions which are Substantially Changed must be renamed to
-avoid use of the name of the Original Version or similar names entirely.
-(c) Modified Versions which are not Substantially Changed must be
-renamed to both (i) retain the name of the Original Version and (ii) add
-additional naming elements to distinguish the Modified Version from the
-Original Version. The name of such Modified Versions must be the name of
-the Original Version, with "derivative X" where X represents the name of
-the new work, appended to that name.
-
-3) The name(s) of the Copyright Holder(s) and any contributor to the
-Font Software shall not be used to promote, endorse or advertise any
-Modified Version, except (i) as required by this licence, (ii) to
-acknowledge the contribution(s) of the Copyright Holder(s) or (iii) with
-their explicit written permission.
-
-4) The Font Software, modified or unmodified, in part or in whole, must
-be distributed entirely under this licence, and must not be distributed
-under any other licence. The requirement for fonts to remain under this
-licence does not affect any document created using the Font Software,
-except any version of the Font Software extracted from a document
-created using the Font Software may only be distributed under this
-licence.
-
-TERMINATION
-This licence becomes null and void if any of the above conditions are
-not met.
-
-DISCLAIMER
-THE FONT SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND,
-EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO ANY WARRANTIES OF
-MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT OF
-COPYRIGHT, PATENT, TRADEMARK, OR OTHER RIGHT. IN NO EVENT SHALL THE
-COPYRIGHT HOLDER BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER LIABILITY,
-INCLUDING ANY GENERAL, SPECIAL, INDIRECT, INCIDENTAL, OR CONSEQUENTIAL
-DAMAGES, WHETHER IN AN ACTION OF CONTRACT, TORT OR OTHERWISE, ARISING
-FROM, OUT OF THE USE OR INABILITY TO USE THE FONT SOFTWARE OR FROM OTHER
-DEALINGS IN THE FONT SOFTWARE.

-"""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()

-    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

-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.

-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
-        ``application/octet-stream``. If a filename looks like a text
-        mimetype, the ``utf-8`` charset is added to it.
-
-    .. versionadded:: 0.6
-        Added ``fallback_mimetype``.
-
-    .. versionchanged:: 0.5
-        Added ``cache_timeout``.

-"""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
-application.
-
-If matching succeeded but the URL rule was incompatible to the given
-method (for example there were only rules for ``GET`` and ``HEAD`` but
-routing tried to match a ``POST`` request) a ``MethodNotAllowed``
-exception is raised.

-class Rule(RuleFactory):
-    """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`` he 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.

-        `HTTP_HOST` if provided) as used `server_name` with disabled subdomain
-        feature.
-
-        If `subdomain` is `None` but an environment and a server name is
-        provided it will calculate the current subdomain automatically.
-        Example: `server_name` is ``'example.com'`` and the `SERVER_NAME`
-        in the wsgi `environ` is ``'staging.dev.example.com'`` the calculated
-        subdomain will be ``'staging.dev'``.
-
-        If the object passed as environ has an environ attribute, the value of
-        this attribute is used instead.  This allows you to pass request
-        objects.  Additionally `PATH_INFO` added as a default of the
-        :class:`MapAdapter` so that you don't have to pass the path info to
-        the match method.

-            If the passed server name specifies port 443, it will match

-        """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'),
-        ...     Rule('/downloads/<int:id>', endpoint='downloads/show')
-        ... ])
-        >>> urls = m.bind("example.com", "/")
-        >>> urls.match("/", "GET")
-        ('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/
-        >>> urls.match("/missing")

-                       method specified on binding.
-        :param return_rule: return the rule that matched instead of just the

-        `match` you call `build` and pass it the endpoint and a dict of

-
-        The `build` function also accepts an argument called `force_external`
-        which, if you set it to `True` will force external URLs. Per default
-        external URLs (include the server name) will only be used if the
-        target URL is on a different subdomain.

-
-        Because URLs cannot contain non ASCII data you will always get
-        bytes back.  Non ASCII characters are urlencoded with the
-        charset defined on the map instance.
-
-        Additional values are converted to strings and appended to the URL as
-        URL querystring parameters:

-

-        '/?p=z&q=a&q=b'
-
-        If a rule does not exist when building a `BuildError` exception is
-        raised.
-
-        The build method accepts an argument called `method` which allows you
-        to specify the method you want to have an URL built for if you have
-        different methods for the same endpoint specified.
-
-        :param endpoint: the endpoint of the URL to build.
-        :param values: the values for the URL to build.  Unhandled values are
-                       appended to the URL as query parameters.
-        :param method: the HTTP method for the rule if there are different
-                       URLs for different methods on the same endpoint.
-        :param force_external: enforce full canonical external URLs. If the URL
-                               scheme is not provided, this will generate
-                               a protocol-relative URL.

-                               URL as query string argument.  Disable this
-                               if you want the builder to ignore those.

-        If the value is a path that starts with ``unix://`` it will bind
-        to a Unix socket instead of a TCP socket..
-    :param port: The port for the server.  eg: ``8080``
-    :param application: the WSGI application to execute
-    :param use_reloader: should the server automatically restart the python
-                         process if modules were changed?
-    :param use_debugger: should the werkzeug debugging system be used?
-    :param use_evalex: should the exception evaluation feature be enabled?
-    :param extra_files: a list of files the reloader should watch
-                        additionally to the modules.  For example configuration
-                        files.
-    :param exclude_patterns: List of :mod:`fnmatch` patterns to ignore
-        when running the reloader. For example, ignore cache files that
-        shouldn't reload when updated.
-    :param reloader_interval: the interval for the reloader in seconds.
-    :param reloader_type: the type of reloader to use.  The default is
-                          auto detection.  Valid values are ``'stat'`` and
-                          ``'watchdog'``. See :ref:`reloader` for more

-                     thread?
-    :param processes: if greater than 1 then handle each request in a new process
-                      up to this maximum number of concurrent processes.
-    :param request_handler: optional parameter that can be used to replace
-                            the default one.  You can use this to replace it

-                            subclass.
-    :param static_files: a list or dict of paths for static files.  This works
-                         exactly like :class:`SharedDataMiddleware`, it's actually
-                         just wrapping the application in that middleware before
-                         serving.
-    :param passthrough_errors: set this to `True` to disable the error catching.
-                               This means that the server will die on errors but
-                               it can be useful to hook debuggers in (pdb etc.)
-    :param ssl_context: an SSL context for the connection. Either an
-                        :class:`ssl.SSLContext`, a tuple in the form

-    """This class can be used to conveniently create a WSGI environment
-    for testing purposes.  It can be used to quickly create WSGI environments
-    or request objects from arbitrary data.
-
-    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.
-
-    Files and regular form data can be manipulated independently of each
-    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
-                 and there is a question mark in the `path` everything after
-                 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
-                         don't have to provide this when specifying files
-                         and form data via `data`.
-    :param content_length: The content length for the request.  You don't
-                           have to specify this when providing data via
-                           `data`.
-    :param errors_stream: an optional error stream that is used for
-                          `wsgi.errors`.  Defaults to :data:`stderr`.
-    :param multithread: controls `wsgi.multithread`.  Defaults to `False`.
-    :param multiprocess: controls `wsgi.multiprocess`.  Defaults to `False`.
-    :param run_once: controls `wsgi.run_once`.  Defaults to `False`.
-    :param headers: an optional list or :class:`Headers` object of headers.
-    :param data: a string or dict of form data or a file-object.
-                 See explanation above.
-    :param json: An object to be serialized and assigned to ``data``.
-        Defaults the content type to ``"application/json"``.
-        Serialized with the function assigned to :attr:`json_dumps`.
-    :param environ_base: an optional dict of environment defaults.
-    :param environ_overrides: an optional dict of environment overrides.
-    :param charset: the charset used to encode string data.
-    :param auth: An authorization object to use for the
-        ``Authorization`` header value. A ``(username, password)`` tuple
-        is a shortcut for ``Basic`` authorization.

-

-    stream is exhausted and the caller tries to get more bytes from it
-    :func:`on_exhausted` is called which by default returns an empty
-    string.  The return value of that function is forwarded
-    to the reader function.  So if it returns an empty string
-    :meth:`read` will return an empty string as well.
-
-    The limit however must never be higher than what the stream can
-    output.  Otherwise :meth:`readlines` will try to read past the

-
-    .. admonition:: Note on WSGI compliance
-
-       calls to :meth:`readline` and :meth:`readlines` are not
-       WSGI compliant because it passes a size argument to the
-       readline methods.  Unfortunately the WSGI PEP is not safely
-       implementable without a size argument to :meth:`readline`
-       because there is no EOF marker in the stream.  As a result
-       of that the use of :meth:`readline` is discouraged.
-
-       For the same reason iterating over the :class:`LimitedStream`
-       is not portable.  It internally calls :meth:`readline`.
-
-       We strongly suggest using :meth:`read` only or using the
-       :func:`make_line_iter` which safely iterates line-based
-       over a WSGI input stream.
-
-    :param stream: the stream to wrap.
-    :param limit: the limit for the stream, must not be longer than
-                  what the string can provide if the stream does not
-                  end with `EOF` (like `wsgi.input`)
