+<#
+.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:

+.Description
+Get-PyVenvConfig parses the values from the pyvenv.cfg file located in the

+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.

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

+## ⚡ Performance
+
+This package offer better performance than its counterpart Chardet. Here are some numbers.
+
+| Package                                       | Accuracy | Mean per file (ms) | File per sec (est) |
+|-----------------------------------------------|:--------:|:------------------:|:------------------:|
+| [chardet](https://github.com/chardet/chardet) |   86 %   |       200 ms       |     5 file/sec     |
+| charset-normalizer                            | **98 %** |     **10 ms**      |    100 file/sec    |

+
+Chardet's performance on larger file (1MB+) are very poor. Expect huge difference on large payload.
+
+> Stats are generated using 400+ files using default parameters. More details on used files, see GHA workflows.
+> And yes, these results might change at any time. The dataset can be updated to include more files.
+> The actual delays heavily depends on your CPU capabilities. The factors should remain the same.
+> Keep in mind that the stats are generous and that Chardet accuracy vs our is measured using Chardet initial capability
+> (eg. Supported Encoding) Challenge-them if you want.
+
+## ✨ Installation
+
+Using pip:
+
+```sh
+pip install charset-normalizer -U
+```
+
+## 🚀 Basic Usage
+
+### CLI
+This package comes with a CLI.
+
+```
+usage: normalizer [-h] [-v] [-a] [-n] [-m] [-r] [-f] [-t THRESHOLD]
+                  file [file ...]
+
+The Real First Universal Charset Detector. Discover originating encoding used
+on text file. Normalize text to unicode.
+
+positional arguments:
+  files                 File(s) to be analysed
+
+optional arguments:
+  -h, --help            show this help message and exit
+  -v, --verbose         Display complementary information about file if any.
+                        Stdout will contain logs about the detection process.
+  -a, --with-alternative
+                        Output complementary possibilities if any. Top-level
+                        JSON WILL be a list.
+  -n, --normalize       Permit to normalize input file. If not set, program
+                        does not write anything.
+  -m, --minimal         Only output the charset detected to STDOUT. Disabling
+                        JSON output.
+  -r, --replace         Replace file when trying to normalize it instead of
+                        creating a new one.
+  -f, --force           Replace file without asking if you are sure, use this
+                        flag with caution.
+  -t THRESHOLD, --threshold THRESHOLD
+                        Define a custom maximum amount of chaos allowed in
+                        decoded content. 0. <= chaos <= 1.
+  --version             Show version information and exit.
+```
+
+```bash
+normalizer ./data/sample.1.fr.srt
+```
+
+or
+
+```bash
+python -m charset_normalizer ./data/sample.1.fr.srt
+```
+
+🎉 Since version 1.4.0 the CLI produce easily usable stdout result in JSON format.
+
+```json
+{
+    "path": "/home/default/projects/charset_normalizer/data/sample.1.fr.srt",
+    "encoding": "cp1252",
+    "encoding_aliases": [
+        "1252",
+        "windows_1252"
+    ],
+    "alternative_encodings": [
+        "cp1254",
+        "cp1256",
+        "cp1258",
+        "iso8859_14",
+        "iso8859_15",
+        "iso8859_16",
+        "iso8859_3",
+        "iso8859_9",
+        "latin_1",
+        "mbcs"
+    ],
+    "language": "French",
+    "alphabets": [
+        "Basic Latin",
+        "Latin-1 Supplement"
+    ],
+    "has_sig_or_bom": false,
+    "chaos": 0.149,
+    "coherence": 97.152,
+    "unicode_path": null,
+    "is_preferred": true
+}
+```
+
+### Python
+*Just print out normalized text*
+```python
+from charset_normalizer import from_path
+
+results = from_path('./my_subtitle.srt')
+
+print(str(results.best()))
+```
+
+*Upgrade your code without effort*
+```python
+from charset_normalizer import detect
+```
+
+The above code will behave the same as **chardet**. We ensure that we offer the best (reasonable) BC result possible.
+
+See the docs for advanced usage : [readthedocs.io](https://charset-normalizer.readthedocs.io/en/latest/)
+
+## 😇 Why
+
+When I started using Chardet, I noticed that it was not suited to my expectations, and I wanted to propose a
+reliable alternative using a completely different method. Also! I never back down on a good challenge!
+
+I **don't care** about the **originating charset** encoding, because **two different tables** can
+produce **two identical rendered string.**
+What I want is to get readable text, the best I can. 
+
+In a way, **I'm brute forcing text decoding.** How cool is that ? 😎
+
+Don't confuse package **ftfy** with charset-normalizer or chardet. ftfy goal is to repair unicode string whereas charset-normalizer to convert raw file in unknown encoding to unicode.
+
+## 🍰 How
+
+  - Discard all charset encoding table that could not fit the binary content.
+  - Measure noise, or the mess once opened (by chunks) with a corresponding charset encoding.
+  - Extract matches with the lowest mess detected.
+  - Additionally, we measure coherence / probe for a language.
+
+**Wait a minute**, what is noise/mess and coherence according to **YOU ?**
+
+*Noise :* I opened hundred of text files, **written by humans**, with the wrong encoding table. **I observed**, then
+**I established** some ground rules about **what is obvious** when **it seems like** a mess.
+ I know that my interpretation of what is noise is probably incomplete, feel free to contribute in order to
+ improve or rewrite it.
+
+*Coherence :* For each language there is on earth, we have computed ranked letter appearance occurrences (the best we can). So I thought
+that intel is worth something here. So I use those records against decoded text to check if I can detect intelligent design.
+
+## ⚡ Known limitations
+
+  - Language detection is unreliable when text contains two or more languages sharing identical letters. (eg. HTML (english tags) + Turkish content (Sharing Latin characters))
+  - Every charset detector heavily depends on sufficient content. In common cases, do not bother run detection on very tiny content.
+

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

+Decorators for Humans
+=====================
+
+The goal of the decorator module is to make it easy to define
+signature-preserving function decorators and decorator factories.
+It also includes an implementation of multiple dispatch and other niceties
+(please check the docs). It is released under a two-clauses
+BSD license, i.e. basically you can do whatever you want with it but I am not
+responsible.
+
+Installation
+-------------
+
+If you are lazy, just perform
+
+ ``$ pip install decorator``
+
+which will install just the module on your system.
+
+If you prefer to install the full distribution from source, including
+the documentation, clone the `GitHub repo`_ or download the tarball_, unpack it and run
+
+ ``$ pip install .``
+
+in the main directory, possibly as superuser.
+
+.. _tarball: https://pypi.org/project/decorator/#files
+.. _GitHub repo: https://github.com/micheles/decorator
+
+Testing
+--------
+
+If you have the source code installation you can run the tests with
+
+ `$ python src/tests/test.py -v`
+
+or (if you have setuptools installed)
+
+ `$ python setup.py test`
+
+Notice that you may run into trouble if in your system there
+is an older version of the decorator module; in such a case remove the
+old version. It is safe even to copy the module `decorator.py` over
+an existing one, since we kept backward-compatibility for a long time.
+
+Repository
+---------------
+
+The project is hosted on GitHub. You can look at the source here:
+
+ https://github.com/micheles/decorator
+
+Documentation
+---------------
+
+The documentation has been moved to https://github.com/micheles/decorator/blob/master/docs/documentation.md
+
+From there you can get a PDF version by simply using the print
+functionality of your browser.
+
+Here is the documentation for previous versions of the module:
+
+https://github.com/micheles/decorator/blob/4.3.2/docs/tests.documentation.rst
+https://github.com/micheles/decorator/blob/4.2.1/docs/tests.documentation.rst
+https://github.com/micheles/decorator/blob/4.1.2/docs/tests.documentation.rst
+https://github.com/micheles/decorator/blob/4.0.0/documentation.rst
+https://github.com/micheles/decorator/blob/3.4.2/documentation.rst
+
+For the impatient
+-----------------
+
+Here is an example of how to define a family of decorators tracing slow
+operations:
+
+.. code-block:: python
+
+   from decorator import decorator
+
+   @decorator
+   def warn_slow(func, timelimit=60, *args, **kw):
+       t0 = time.time()
+       result = func(*args, **kw)
+       dt = time.time() - t0
+       if dt > timelimit:
+           logging.warn('%s took %d seconds', func.__name__, dt)
+       else:
+           logging.info('%s took %d seconds', func.__name__, dt)
+       return result
+
+   @warn_slow  # warn if it takes more than 1 minute
+   def preprocess_input_files(inputdir, tempdir):
+       ...
+
+   @warn_slow(timelimit=600)  # warn if it takes more than 10 minutes
+   def run_calculation(tempdir, outdir):
+       ...
+
+Enjoy!

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

+
+    Unlike the ordinary Element factory, the E factory allows you to pass in
+    more than just a tag and some optional attributes; you can also pass in
+    text and other elements.  The text is added as either text or tail
+    attributes, and elements are inserted at the right spot.  Some small
+    examples::
+
+        >>> from lxml import etree as ET
+        >>> from lxml.builder import E
+
+        >>> ET.tostring(E("tag"))
+        '<tag/>'
+        >>> ET.tostring(E("tag", "text"))
+        '<tag>text</tag>'
+        >>> ET.tostring(E("tag", "text", key="value"))
+        '<tag key="value">text</tag>'
+        >>> ET.tostring(E("tag", E("subtag", "text"), "tail"))
+        '<tag><subtag>text</subtag>tail</tag>'
+
+    For simple tags, the factory also allows you to write ``E.tag(...)`` instead
+    of ``E('tag', ...)``::
+
+        >>> ET.tostring(E.tag())
+        '<tag/>'
+        >>> ET.tostring(E.tag("text"))
+        '<tag>text</tag>'
+        >>> ET.tostring(E.tag(E.subtag("text"), "tail"))
+        '<tag><subtag>text</subtag>tail</tag>'
+
+    Here's a somewhat larger example; this shows how to generate HTML
+    documents, using a mix of prepared factory functions for inline elements,
+    nested ``E.tag`` calls, and embedded XHTML fragments::
+
+        # some common inline elements
+        A = E.a
+        I = E.i
+        B = E.b
+
+        def CLASS(v):
+            # helper function, 'class' is a reserved word
+            return {'class': v}
+
+        page = (
+            E.html(
+                E.head(
+                    E.title("This is a sample document")
+                ),
+                E.body(
+                    E.h1("Hello!", CLASS("title")),
+                    E.p("This is a paragraph with ", B("bold"), " text in it!"),
+                    E.p("This is another paragraph, with a ",
+                        A("link", href="http://www.python.org"), "."),
+                    E.p("Here are some reserved characters: <spam&egg>."),
+                    ET.XML("<p>And finally, here is an embedded XHTML fragment.</p>"),
+                )
+            )
+        )
+
+        print ET.tostring(page)
+
+    Here's a prettyprinted version of the output from the above script::
+
+        <html>
+          <head>
+            <title>This is a sample document</title>
+          </head>
+          <body>
+            <h1 class="title">Hello!</h1>
+            <p>This is a paragraph with <b>bold</b> text in it!</p>
+            <p>This is another paragraph, with <a href="http://www.python.org">link</a>.</p>
+            <p>Here are some reserved characters: &lt;spam&amp;egg&gt;.</p>
+            <p>And finally, here is an embedded XHTML fragment.</p>
+          </body>
+        </html>
+
+    For namespace support, you can pass a namespace map (``nsmap``)
+    and/or a specific target ``namespace`` to the ElementMaker class::
+
+        >>> E = ElementMaker(namespace="http://my.ns/")
+        >>> print(ET.tostring( E.test ))
+        <test xmlns="http://my.ns/"/>
+
+        >>> E = ElementMaker(namespace="http://my.ns/", nsmap={'p':'http://my.ns/'})

+    The public Element class.  All custom Element classes must inherit

+
+    BIG FAT WARNING: Subclasses *must not* override __init__ or
+    __new__ as it is absolutely undefined when these objects will be
+    created or destroyed.  All persistent state of Elements must be
+    stored in the underlying XML.  If you really need to initialize
+    the object after creation, you can implement an ``_init(self)``
+    method that will be called directly after object creation.
+
+    Subclasses of this class can be instantiated to create a new
+    Element.  By default, the tag name will be the class name and the
+    namespace will be empty.  You can modify this with the following
+    class attributes:
+
+    * TAG - the tag name, possibly containing a namespace in Clark
+      notation
+
+    * NAMESPACE - the default namespace URI, unless provided as part
+      of the TAG attribute.
+
+    * HTML - flag if the class is an HTML tag, as opposed to an XML
+      tag.  This only applies to un-namespaced tags and defaults to
+      false (i.e. XML).
+
+    * PARSER - the parser that provides the configuration for the
+      newly created document.  Providing an HTML parser here will
+      default to creating an HTML element.
+
+    In user code, the latter three are commonly inherited in class
+    hierarchies that implement a common namespace.

+lxml-based doctest output comparison.
+
+Note: normally, you should just import the `lxml.usedoctest` and
+`lxml.html.usedoctest` modules from within a doctest, instead of this
+one::
+
+    >>> import lxml.usedoctest # for XML output
+
+    >>> import lxml.html.usedoctest # for HTML output
+
+To use this module directly, you must call ``lxmldoctest.install()``,
+which will cause doctest to use this in all subsequent calls.
+
+This changes the way output is checked and comparisons are made for
+XML or HTML-like content.
+
+XML or HTML content is noticed because the example starts with ``<``
+(it's HTML if it starts with ``<html``).  You can also use the
+``PARSE_HTML`` and ``PARSE_XML`` flags to force parsing.
+
+Some rough wildcard-like things are allowed.  Whitespace is generally
+ignored (except in attributes).  In text (attributes and text in the
+body) you can use ``...`` as a wildcard.  In an example it also
+matches any trailing tags in the element, though it does not match
+leading tags.  You may create a tag ``<any>`` or include an ``any``
+attribute in the tag.  An ``any`` tag matches any tag, while the
+attribute matches any and all attributes.
+
+When a match fails, the reformatted example and gotten text is
+displayed (indented), and a rough diff-like output is given.  Anything
+marked with ``+`` is in the output but wasn't supposed to be, and
+similarly ``-`` means its in the example but wasn't in the output.
+
+You can disable parsing on one line with ``# doctest:+NOPARSE_MARKUP``

+
+        The ``doctype`` option allows passing in a plain string that will

+
+        The ``inclusive_ns_prefixes`` should be a list of namespace strings
+        (i.e. ['xs', 'xsi']) that will be promoted to the top-level element

+    (string) and 'xml_declaration' (bool).  Note that changing the
+    encoding to a non UTF-8 compatible encoding will enable a
+    declaration by default.
+
+    You can also serialise to a Unicode string without declaration by
+    passing the name ``'unicode'`` as encoding (or the ``str`` function
+    in Py3 or ``unicode`` in Py2).  This changes the return value from
+    a byte string to an unencoded unicode string.
+
+    The keyword argument 'pretty_print' (bool) enables formatted XML.
+
+    The keyword argument 'method' selects the output method: 'xml',
+    'html', plain 'text' (text content without tags), 'c14n' or 'c14n2'.
+    Default is 'xml'.
+
+    With ``method="c14n"`` (C14N version 1), the options ``exclusive``,
+    ``with_comments`` and ``inclusive_ns_prefixes`` request exclusive
+    C14N, include comments, and list the inclusive prefixes respectively.
+
+    With ``method="c14n2"`` (C14N version 2), the ``with_comments`` and
+    ``strip_text`` options control the output of comments and text space
+    according to C14N 2.0.
+
+    Passing a boolean value to the ``standalone`` option will output
+    an XML declaration with the corresponding ``standalone`` flag.
+
+    The ``doctype`` option allows passing in a plain string that will
+    be serialised before the XML tree.  Note that passing in non
+    well-formed content here will make the XML output non well-formed.
+    Also, an existing doctype in the document tree will not be removed
+    when serialising an ElementTree instance.
+
+    You can prevent the tail text of the element from being serialised
+    by passing the boolean ``with_tail`` option.  This has no impact
+    on the tail text of children, which will always be serialised.

+    without creating a copy first, and the capsule destructor will not be
+    called.  The document will then eventually be cleaned up by lxml using
+    the libxml2 API function ``xmlFreeDoc()`` once it is no longer used.

+    The ``encoding`` argument controls the output encoding (defaults to
+    ASCII, with &#...; character references for any characters outside
+    of ASCII).  Note that you can pass the name ``'unicode'`` as
+    ``encoding`` argument to serialise to a Unicode string.
+
+    The ``method`` argument defines the output method.  It defaults to
+    'html', but can also be 'xml' for xhtml output, or 'text' to
+    serialise to plain text without markup.
+
+    To leave out the tail text of the top-level element that is being
+    serialised, pass ``with_tail=False``.
+
+    The ``doctype`` option allows passing in a plain string that will
+    be serialised before the XML tree.  Note that passing in non
+    well-formed content here will make the XML output non well-formed.
+    Also, an existing doctype in the document tree will not be removed
+    when serialising an ElementTree instance.
+
+    Example::
+
+        >>> from lxml import html
+        >>> root = html.fragment_fromstring('<p>Hello<br>world!</p>')
+
+        >>> html.tostring(root)

+    """
+    Instances cleans the document of each of the possible offending
+    elements.  The cleaning is controlled by attributes; you can
+    override attributes in a subclass, or set them in the constructor.
+
+    ``scripts``:
+        Removes any ``<script>`` tags.
+
+    ``javascript``:
+        Removes any Javascript, like an ``onclick`` attribute. Also removes stylesheets
+        as they could contain Javascript.
+
+    ``comments``:
+        Removes any comments.
+
+    ``style``:
+        Removes any style tags.
+
+    ``inline_style``
+        Removes any style attributes.  Defaults to the value of the ``style`` option.
+
+    ``links``:
+        Removes any ``<link>`` tags
+
+    ``meta``:
+        Removes any ``<meta>`` tags
+
+    ``page_structure``:
+        Structural parts of a page: ``<head>``, ``<html>``, ``<title>``.
+
+    ``processing_instructions``:
+        Removes any processing instructions.
+
+    ``embedded``:
+        Removes any embedded objects (flash, iframes)
+
+    ``frames``:
+        Removes any frame-related tags
+
+    ``forms``:
+        Removes any form tags
+
+    ``annoying_tags``:
+        Tags that aren't *wrong*, but are annoying.  ``<blink>`` and ``<marquee>``
+
+    ``remove_tags``:
+        A list of tags to remove.  Only the tags will be removed,
+        their content will get pulled up into the parent tag.
+
+    ``kill_tags``:
+        A list of tags to kill.  Killing also removes the tag's content,
+        i.e. the whole subtree, not just the tag itself.
+
+    ``allow_tags``:
+        A list of tags to include (default include all).
+
+    ``remove_unknown_tags``:
+        Remove any tags that aren't standard parts of HTML.
+
+    ``safe_attrs_only``:
+        If true, only include 'safe' attributes (specifically the list
+        from the feedparser HTML sanitisation web site).
+
+    ``safe_attrs``:
+        A set of attribute names to override the default list of attributes
+        considered 'safe' (when safe_attrs_only=True).
+
+    ``add_nofollow``:
+        If true, then any <a> tags will have ``rel="nofollow"`` added to them.
+
+    ``host_whitelist``:
+        A list or set of hosts that you can use for embedded content
+        (for content like ``<object>``, ``<link rel="stylesheet">``, etc).
+        You can also implement/override the method
+        ``allow_embedded_url(el, url)`` or ``allow_element(el)`` to
+        implement more complex rules for what can be embedded.
+        Anything that passes this test will be shown, regardless of
+        the value of (for instance) ``embedded``.
+
+        Note that this parameter might not work as intended if you do not
+        make the links absolute before doing the cleaning.
+
+        Note that you may also need to set ``whitelist_tags``.
+
+    ``whitelist_tags``:
+        A set of tags that can be included with ``host_whitelist``.
+        The default is ``iframe`` and ``embed``; you may wish to
+        include other tags like ``script``, or you may want to
+        implement ``allow_embedded_url`` for more control.  Set to None to
+        include all tags.

+    """An ISO Schematron validator.
+
+    Pass a root Element or an ElementTree to turn it into a validator.
+    Alternatively, pass a filename as keyword argument 'file' to parse from
+    the file system.
+
+    Schematron is a less well known, but very powerful schema language.
+    The main idea is to use the capabilities of XPath to put restrictions on
+    the structure and the content of XML documents.
+
+    The standard behaviour is to fail on ``failed-assert`` findings only
+    (``ASSERTS_ONLY``).  To change this, you can either pass a report filter
+    function to the ``error_finder`` parameter (e.g. ``ASSERTS_AND_REPORTS``
+    or a custom ``XPath`` object), or subclass isoschematron.Schematron for
+    complete control of the validation process.
+
+    Built on the Schematron language 'reference' skeleton pure-xslt
+    implementation, the validator is created as an XSLT 1.0 stylesheet using
+    these steps:
+
+     0) (Extract from XML Schema or RelaxNG schema)
+     1) Process inclusions
+     2) Process abstract patterns
+     3) Compile the schematron schema to XSLT
+
+    The ``include`` and ``expand`` keyword arguments can be used to switch off
+    steps 1) and 2).
+    To set parameters for steps 1), 2) and 3) hand parameter dictionaries to the
+    keyword arguments ``include_params``, ``expand_params`` or
+    ``compile_params``.
+    For convenience, the compile-step parameter ``phase`` is also exposed as a
+    keyword argument ``phase``. This takes precedence if the parameter is also
+    given in the parameter dictionary.
+
+    If ``store_schematron`` is set to True, the (included-and-expanded)
+    schematron document tree is stored and available through the ``schematron``
+    property.
+    If ``store_xslt`` is set to True, the validation XSLT document tree will be
+    stored and can be retrieved through the ``validator_xslt`` property.
+    With ``store_report`` set to True (default: False), the resulting validation
+    report document gets stored and can be accessed as the ``validation_report``
+    property.

+     OVERVIEW - iso_abstract_expand.xsl
+     
+	    This is a preprocessor for ISO Schematron, which implements abstract patterns. 
+	    It also 
+	       	* extracts a particular schema using an ID, where there are multiple 
+             schemas, such as when they are embedded in the same NVDL script 
+           * allows parameter substitution inside @context, @test, @select, @path
+	    	   * experimentally, allows parameter recognition and substitution inside
+             text (NOTE: to be removed, for compataibility with other implementations,   
+             please do not use this) 
+		
+		This should be used after iso-dsdl-include.xsl and before the skeleton or
+		meta-stylesheet (e.g. iso-svrl.xsl) . It only requires XSLT 1.
+

+<!-- 
+     OVERVIEW : iso_dsdl_include.xsl
+     
+	    This is an inclusion preprocessor for the non-smart text inclusions
+	    of ISO DSDL. It handles 
+	    	<relax:extRef> for ISO RELAX NG
+	    	<sch:include>  for ISO Schematron and Schematron 1.n
+	    	<sch:extends>  for 2009 draft ISO Schematron
+	    	<xi:xinclude>  simple W3C XIncludes for ISO NVRL and DSRL 
+	    	<crdl:ref>     for draft ISO CRDL
+	    	<dtll:include> for draft ISO DTLL
+	    	<* @xlink:href> for simple W3C XLink 1.1 embedded links
+	    	
+		 
+		This should be the first in any chain of processing. It only requires
+		XSLT 1. Each kind of inclusion can be turned off (or on) on the command line.
+		
+		Ids in fragment identifiers or xpointers will be sought in the following
+		order:
+		    * @xml:id
+		    * id() for typed schemas (e.g. from DTD) [NOTE: XInclude does not support this]
+		    * untyped @id 
+		    
+	The proposed behaviour for the update to ISO Schematron has been implemented. If an
+	include points to an element with the same name as the parent, then that element's
+	contents will be included. This supports the merge style of inclusion.    
+	
+	When an inclusion is made, it is preceded by a PI with target DSDL_INCLUDE_START
+	and the href and closed by a PI with target DSDL_INCLUDE_START and the href. This is
+	to allow better location of problems, though only to the file level. 
+	
+	Limitations:
+	* No rebasing: relative paths will be interpreted based on the initial document's
+	path, not the including document. (Severe limitation!)
+	* No checking for circular references
+	* Not full xpointers: only ID matching
+	* <relax:include> not implemented 
+	* XInclude handling of xml:base and xml:lang not implemented   
+-->
+<!-- 
+  VERSION INFORMATION
+	2009-02-25 
+	* Update DSDL namespace to use schematron.com
+	* Tested with SAXON9, Xalan 2.7.1, IE7, 
+	* IE does not like multiple variables in same template with same name: rename.   
+	2008-09-18
+	* Remove new behaviour for include, because it conflicts with existing usage [KH]
+	* Add extends[@href] element with that merge functionality
+	* Generate PIs to notate source of inclusions for potential better diagnostics
+	
+	2008-09-16
+	* Fix for XSLT1
+	
+	2008-08-28
+	* New behaviour for schematron includes: if the pointed to element is the same as the current,
+	include the children.
+	
+	2008-08-20
+	* Fix bug: in XSLT1 cannot do $document/id('x') but need to use for-each
+	
+	2008-08-04
+	* Add support for inclusions in old namespace  
+	
+	2008-08-03
+	* Fix wrong param name include-relaxng & include-crdl (KH, PH)
+	* Allow inclusion of XSLT and XHTML (KH)
+	* Fix inclusion of fragments (KH)
+	
+	2008-07-25
+	* Add selectable input parameter
+	
+	2008-07-24  
+	* RJ New

+   OVERVIEW
+   
+   ASCC/Schematron.com Skeleton Module for ISO Schematron (for XSLT1 systems)
+   
+   ISO Schematron is a language for making assertion about the presence or absence
+   of patterns in XML documents. It is typically used for as a schema language, or
+   to augment existing schema languages, and to check business rules. It is very
+   powerful, yet quite simple: a developer only need know XPath and about five other
+   elements.
+   
+   This is an open source implementation of ISO Schematron in XSLT. Although ISO does
+   not allow reference implementations which might compete with the text of the
+   standard, this code has been compiled by Rick Jelliffe, inventor of Schematron
+   and editor of the ISO standard; so developers can certainly use it as an 
+   unofficial reference implementation for clarification. 
+   
+   This implementation is based on one by Oliver Becker. API documentation is 
+   available separately; try www.schematron.com for this. Funding for this
+   stylesheet over the years has come from Topologi Pty. Ltd., Geotempo Ltd.,
+   and ASCC, Tapei.
+   
+   There are two versions of this skeleton: one is tailored for XSLT1 processors
+   and the other is tailored for XSLT2 processors. Future versions of the
+   XSLT2 skeleton may support more features than that the XSLT 1 skeleton.
+-->
+<!--
+   TIPS
+      
+   A tip for new users of Schematron: make your assertions contain positive messages
+   about what is expected, rather than error messages. For example, use the form
+   "An X should have a Y, because Z". 
+   
+   Another tip is that Schematron provides an
+   element <sch:ns> for declaring the namespaces and prefixes used in Xpaths in 
+   attribute values; it does not extend the XML Namespaces mechanism: if a name
+   in an XPath has a prefix, there must be an <sch:ns> element for that prefix; if
+   a name in an XPath does not have a prefix, it is always in no namespace.
+   
+   A tip for implementers of Schematron, either using this API or re-implementing it:
+   make the value of the diagnostics, flags and richer features available if possible;
+   Schematron has many of the optional richer features which, if implemented, provide
+   a compelling alternative approach to validation and business-rules checking compared
+   to other schema languages and programs. 
+   
+   If you create your own meta-stylesheet to override this one, it is a
+   good idea to have both in the same directory and to run the stylesheet
+   from that directory, as many XSLT implementations have ideosyncratic
+   handling of URLs: keep it simple.

+  XSLT VERSION SUPPORT
+
+  XSLT 1:
+     A schema using the standard XSLT 1 query binding will have a /schema/@queryBinding='xslt' or 
+     nothing.
+
+       * Note: XT does not implement key() and will die if given it. 
+       * Add all formal parameters to default templates
+       * Fix missing apply-templates from process-ns and add params back
+
+  EXSLT:  Experimental support
+     A schema using the EXSLT query binding will have a /schema/@queryBinding='exslt'.
+     It is built on XSLT 1. After experience is gained, this binding is expected to be 
+     formalized as part of ISO Schematron, which currently reserves the "exslt" name for this purpose.
+
+     Some EXSLT engines have the extra functions built-in. For these, there is no need to
+     provide library locations. For engines that require the functions, either hard code
+     them in this script or provide them on the command-line argument.
+ 
+-->
+<!--
+   PROCESS INFORMATION
+   
+   This stylesheet compiles a Schematron schema (*.sch) into XSLT code (*.xsl). 
+   The generated XSLT code can then be run against an XML file (*.xml, etc) and
+   will produce validation results.
+   
+   The output of validation results is performed using named templates (process-*). 
+   These can be overridden easily by making a new XSLT stylesheet that imports this 
+   stylesheet but has its own version of the relevant process-* templates. Several
+   of these invoking stylesheets are available: "iso_svrl.xsl", for example generates
+   ISO Schematron Validation Report Language format results.
+   
+   In this version of the stylesheet, the ISO feature called "abstract patterns" is
+   implemented using macro processing: a prior XSLT stage to which converts uses
+   of abstract patterns into normal patterns. If you do not use abstract patterns,
+   it is not necessary to preprocess the schema.
+   
+   To summarize, a basic process flow for some commandline processor is like this:
+     XSLT -input=xxx.sch  -output=xxx.xsl  -stylesheet=iso_schematron_skeleton.xsl
+     XSLT -input=document.xml  -output=xxx-document.results  -stylesheet=xxx.xsl
+   
+   iso_svrl.xslt is an implementation of Schematron that can use this skeleton and
+   generate ISO SVRL reports. A process flow for some commandline processor would
+   be like this:
+     XSLT -input=xxx.sch  -output=xxx.xsl  -stylesheet=iso_svrl.xsl
+     XSLT -input=document.xml  -output=xxx-document.results  -stylesheet=xxx.xsl
+     
+   It is not impossible that ultimately a third stage, to handle macro-preprocessing
+   and inclusion, might be necessary. (The trade-off is in making this XSLT more
+   complex compared to making the outer process more complex.)
+             
+  This version has so far been tested with
+     Saxon 8
+     MSXML 4 (or 6?)   
+
+ Please note that if you are using SAXON and JAXP, then you should use 
+  System.setProperty("javax.xml.transform.TransformerFactory",
+                          "net.sf.saxon.TransformerFactoryImpl");
+ rather than 
+  System.setProperty("javax.xml.xpath.TransformerFactory",
+                           "net.sf.saxon.TransformerFactoryImpl");
+ which is does not work, at least for the versions of SAXON we tried.

+   Version: 2008-07-14 minor update for inclusion experiments
+   	* RJ Clean up zero-length fragment test on include
+   	* RJ Add experimental support for include containers 
+   	* RJ For path generation, test for //iso:schema not just /iso:schema, for potential embedded Schematron support   
+   	* RJ Don't generate double error messages for old namespace elements
+   	* RJ Experimental iso:rule/iso:title just kept as comment (bigger request Uche Ogbuji)
+   	* RJ Remove spurious debug messages
+   	* RJ Fix bug that prevented including patterns in this (report Roger
+   	Costello)
+  
+   Version: 2007-10-17
+     From this version on I am forking XSLT2 support to a different version of the script.
+     This is due to the increasingly horrible state of the namespace handling code as well
+     as other inconsistencies between the major implementations of different versions.
+     The intent is that future versions of this will have XSLT2 isms removed and be simplified
+     to cope with only XSLT1 and EXLST. Note that though this version is called
+     iso_schematron_skeleton_for_xslt1, the various meta-stylesheets will continue to just call
+     iso_schematron_skeleton: it is up to you to rename the stylesheet to the one you want to
+     use.
+
+       * RJ fix FULL-PATH problem with attribute names
+
+
+   Version: 2007-07-19

+    	* DPC Remove "optimize" parameter
+    	* DPC Add autodetecting optimize parameter attribute to skip checking attribute

+    
+   Version: 2007-04-04
+   	* RJ debug mode param

+   		  Move process-ns to outside the stylesheet body.
+   		* DP, FG, fix handling of xslt:key

+          * Be strict about queryBinding spelling errors
+          * Extra comments on the different queryBindings
+          * KH Add option "message-paths" to generate XPath from output 
+          * KH Add option "terminate" to halt with an error after the first assertion
+          * KH refactor paths in schematron-full-path

+           * Add many extra parameters to the process-* calls, so that almost
+           all the information in the schema can be provided to client programs.
+           Also, rearrange the parameters to fit in with the ISO schema, which
+           has "rich" and "linkable" attribute groups.

+           * remove legacy templates for the old ASCC namespace and no namespace, 
+              and use an import statement instead. Much cleaner now!
+           * patterns use @id not @name
+           * titles can contain sub-elements
+           * start change sch:rule to allow attributes, PIs and comments

+    Contributors: Rick Jelliffe (original), Oliver Becker (architecture, XSLT2), 
+             Miloslav Nic (diagnostic, phase, options), Ludwig Svenonius (abstract)
+             Uche Ogbuji (misc. bug fixes), Jim Ancona (SAXON workaround),
+	 	     Francis Norton (generate-id-from-path), Robert Leftwich, Bryan Rasmussen,
+             Dave Pawson (include, fallback), Florent Georges (namespaces, exslt, attribute
+             context), Benoit Maisonny (attribute context), John Dumps (process-message newline),
+             Cliff Stanford (diagnostics and other newlines)
+
+    
+    KNOWN TYPICAL LIMITATIONS:
+      * Don't use <sch:ns prefix="xsl" .../> with a namespace other than the standard
+      XSLT one. This would be a bizarre thing to do anyway. 
+      * Don't use other prefixes for the XSLT namespace either; some implementations will
+      not handle it correctly.
+     
+     EXTENSIONS:
+      ISO Schematron is designed as a framework with some standard query language
+      bindings. If you need to support other features, please do so safely by making
+      up your own @queryLanguage name: this makes it clear that your schema requires
+      special features. For example, default ISO Schematron does not support user
+      defined functions; so if you want to use the user defined function feature
+      in XSLT, you need to have a schema with some queryBinding attribute name like
+      "XSLT-with-my-functions" or whatever.

+
+   Implementation of Schematron Validation Report Language from ISO Schematron
+   ISO/IEC 19757 Document Schema Definition Languages (DSDL) 
+     Part 3: Rule-based validation  Schematron 
+     Annex D: Schematron Validation Report Language 
+
+  This ISO Standard is available free as a Publicly Available Specification in PDF from ISO.
+  Also see www.schematron.com for drafts and other information.
+
+  This implementation of SVRL is designed to run with the "Skeleton" implementation 
+  of Schematron which Oliver Becker devised. The skeleton code provides a 
+  Schematron implementation but with named templates for handling all output; 
+  the skeleton provides basic templates for output using this API, but client
+  validators can be written to import the skeleton and override the default output
+  templates as required. (In order to understand this, you must understand that
+  a named template such as "process-assert" in this XSLT stylesheet overrides and
+  replaces any template with the same name in the imported skeleton XSLT file.)
+
+  The other important thing to understand in this code is that there are different
+  versions of the Schematron skeleton. These track the development of Schematron through
+  Schematron 1.5, Schematron 1.6 and now ISO Schematron. One only skeleton must be
+  imported. The code has templates for the different skeletons commented out for 
+  convenience. ISO Schematron has a different namespace than Schematron 1.5 and 1.6;
+  so the ISO Schematron skeleton has been written itself with an optional import
+  statement to in turn import the Schematron 1.6 skeleton. This will allow you to 
+  validate with schemas from either namespace.
+  
+
+  History:  
+    2009-03-18
+    	* Fix atrribute with space "see " which generates wrong name in some processors
+    2008-08-11
+   		* RJ Fix attribute/@select which saxon allows  in XSLT 1
+   2008-08-07
+    	* RJ Add output-encoding attribute to specify final encoding to use
+    	* Alter allow-foreign functionality so that Schematron span, emph and dir elements make 
+    	  it to the output, for better formatting and because span can be used to mark up
+    	  semantically interesting information embedded in diagnostics, which reduces the
+    	  need to extend SVRL itself
+    	* Diagnostic-reference had an invalid attribute @id that duplicated @diagnostic: removed
+  	2008-08-06
+    	* RJ Fix invalid output:  svrl:diagnostic-reference is not contained in an svrl:text
+    	* Output comment to SVRL file giving filename if available (from command-line parameter)
+  	2008-08-04
+  		* RJ move sch: prefix to schold: prefix to prevent confusion (we want people to
+  		be able to switch from old namespace to new namespace without changing the
+  		sch: prefix, so it is better to keep that prefix completely out of the XSLT)
+  		* Extra signature fixes (PH)
+    2008-08-03
+    	* Repair missing class parameter on process-p
+    2008-07-31
+    	* Update skeleton names
+    2007-04-03 
+    	* Add option generate-fired-rule (RG)
+    2007-02-07
+    	* Prefer true|false for parameters. But allow yes|no on some old for compatability
+    	* DP Diagnostics output to svrl:text. Diagnosis put out after assertion text.
+      	* Removed non-SVRL elements and attributes: better handled as an extra layer that invokes this one
+      	* Add more formal parameters
+      	* Correct confusion between $schemaVersion and $queryBinding
+     	* Indent
+     	* Validate against RNC schemas for XSLT 1 and 2 (with regex tests removed)
+     	* Validate output with UniversalTest.sch against RNC schema for ISO SVRL
+    	
+    2007-02-01
+       	* DP. Update formal parameters of overriding named templates to handle more attributes.
+       	* DP. Refactor handling of rich and linkable parameters to a named template.
+
+    2007-01-22
+    	* DP change svrl:ns to svrl:ns-in-attribute-value
+		* Change default when no queryBinding from "unknown" to "xslt"
+	
+    2007-01-18:
+     	* Improve documentation
+     	* KH Add command-line options to generate paths or not 
+       	* Use axsl:attribute rather than xsl:attribute to shut XSLT2 up
+       	* Add extra command-line options to pass to the iso_schematron_skeleton
+  
+    2006-12-01: iso_svrl.xsl Rick Jelliffe, 
+          * update namespace, 
+          * update phase handling,
+          * add flag param to process-assert and process-report & @ flag on output
+  
+    2001: Conformance1-5.xsl Rick Jelliffe, 
+          * Created, using the skeleton code contributed by Oliver Becker

+ISO SCHEMATRON 2010
+
+XSLT implementation by Rick Jelliffe with assistance from members of Schematron-love-in maillist.
+
+2010-04-21
+
+Two distributions are available. One is for XSLT1 engines. 
+The other is for XSLT2 engines, such as SAXON 9.
+
+
+This version of Schematron splits the process into a pipeline of several different XSLT stages.
+
+1) First, preprocess your Schematron schema with iso_dsdl_include.xsl.  
+This is a macro processor to assemble the schema from various parts. 
+If your schema is not in separate parts, you can skip this stage.
+This stage also generates error messages for some common XPath syntax problems.
+
+2) Second, preprocess the output from stage 1 with iso_abstract_expand.xsl.  
+This is a macro processor to convert abstract patterns to real patterns. 
+If your schema does not use abstract patterns, you can skip this
+stage.
+
+3) Third, compile the Schematron schema into an XSLT script. 
+This will typically use iso_svrl_for_xslt1.xsl or iso_svrl_for_xslt2.xsl 
+(which in turn invoke iso_schematron_skeleton_for_xslt1.xsl or iso_schematron_skeleton_for_saxon.xsl)
+However, other "meta-stylesheets" are also in common use; the principle of operation is the same.
+If your schema uses Schematron phases, supply these as command line/invocation parameters
+to this process.
+
+4) Fourth, run the script generated by stage 3 against the document being validated.
+If you are using the SVRL script, then the output of validation will be an XML document.
+If your schema uses Schematron parameters, supply these as command line/invocation parameters
+to this process. 
+
+
+The XSLT2 distribution also features several next generation features, 
+such as validating multiple documents. See the source code for details.
+
+Schematron assertions can be written in any language, of course; the file
+sch-messages-en.xhtml contains the diagnostics messages from the XSLT2 skeleton
+in English, and this can be used as template to localize the skeleton's
+error messages. Note that typically programming errors in Schematron are XPath
+errors, which requires localized messages from the XSLT engine.
+

+    u"""iterparse(self, source, events=("end",), tag=None, \
+                  attribute_defaults=False, dtd_validation=False, \
+                  load_dtd=False, no_network=True, remove_blank_text=False, \

+                  html=False, recover=None, huge_tree=False, schema=None)
+
+    Incremental parser.
+
+    Parses XML into a tree and generates tuples (event, element) in a
+    SAX-like fashion. ``event`` is any of 'start', 'end', 'start-ns',
+    'end-ns'.
+
+    For 'start' and 'end', ``element`` is the Element that the parser just
+    found opening or closing.  For 'start-ns', it is a tuple (prefix, URI) of
+    a new namespace declaration.  For 'end-ns', it is simply None.  Note that
+    all start and end events are guaranteed to be properly nested.
+
+    The keyword argument ``events`` specifies a sequence of event type names
+    that should be generated.  By default, only 'end' events will be
+    generated.
+
+    The additional ``tag`` argument restricts the 'start' and 'end' events to
+    those elements that match the given tag.  The ``tag`` argument can also be
+    a sequence of tags to allow matching more than one tag.  By default,
+    events are generated for all elements.  Note that the 'start-ns' and
+    'end-ns' events are not impacted by this restriction.
+
+    The other keyword arguments in the constructor are mainly based on the
+    libxml2 parser configuration.  A DTD will also be loaded if validation or
+    attribute default values are requested.
+
+    Available boolean keyword arguments:
+     - attribute_defaults: read default attributes from DTD
+     - dtd_validation: validate (if DTD is available)
+     - load_dtd: use DTD for parsing
+     - no_network: prevent network access for related files
+     - remove_blank_text: discard blank text nodes
+     - remove_comments: discard comments
+     - remove_pis: discard processing instructions
+     - strip_cdata: replace CDATA sections by normal text content (default: True)
+     - compact: safe memory for short text content (default: True)
+     - resolve_entities: replace entities by their text value (default: True)
+     - huge_tree: disable security restrictions and support very deep trees
+                  and very long text content (only affects libxml2 2.7+)
+     - html: parse input as HTML (default: XML)
+     - recover: try hard to parse through broken input (default: True for HTML,
+                False otherwise)
+
+    Other keyword arguments:
+     - encoding: override the document encoding
+     - schema: an XMLSchema to validate against

+
+    The XML parser.
+
+    Parsers can be supplied as additional argument to various parse
+    functions of the lxml API.  A default parser is always available
+    and can be replaced by a call to the global function
+    'set_default_parser'.  New parsers can be created at any time
+    without a major run-time overhead.
+
+    The keyword arguments in the constructor are mainly based on the
+    libxml2 parser configuration.  A DTD will also be loaded if DTD
+    validation or attribute default values are requested (unless you
+    additionally provide an XMLSchema from which the default
+    attributes can be read).
+
+    Available boolean keyword arguments:
+
+    - attribute_defaults - inject default attributes from DTD or XMLSchema
+    - dtd_validation     - validate against a DTD referenced by the document
+    - load_dtd           - use DTD for parsing
+    - no_network         - prevent network access for related files (default: True)
+    - ns_clean           - clean up redundant namespace declarations
+    - recover            - try hard to parse through broken XML
+    - remove_blank_text  - discard blank text nodes that appear ignorable
+    - remove_comments    - discard comments
+    - remove_pis         - discard processing instructions
+    - strip_cdata        - replace CDATA sections by normal text content (default: True)
+    - compact            - save memory for short text content (default: True)
+    - collect_ids        - use a hash table of XML IDs for fast access (default: True, always True with DTD validation)
+    - resolve_entities   - replace entities by their text value (default: True)

+

+
+    - encoding - override the document encoding (note: libiconv encoding name)
+    - target   - a parser target object that will receive the parse events
+    - schema   - an XMLSchema to validate against
+
+    Note that you should avoid sharing parsers between threads.  While this is

+             xf.write_declaration(standalone=True)
+             xf.write_doctype('<!DOCTYPE root SYSTEM "some.dtd">')
+
+             # generate an element (the root element)
+             with xf.element('root'):
+                  # write a complete Element into the open root element
+                  xf.write(etree.Element('test'))
+
+                  # generate and write more Elements, e.g. through iterparse
+                  for element in generate_some_elements():
+                      # serialise generated elements into the XML file
+                      xf.write(element)

+                  xf.write(etree.Element('start'), "text", etree.Element('end'))
+
+    If 'output_file' is a file(-like) object, passing ``close=True`` will
+    close it when exiting the context manager.  By default, it is left
+    to the owner to do that.  When a file path is used, lxml will take care
+    of opening and closing the file itself.  Also, when a compression level
+    is set, lxml will deliberately close the file to make sure all data gets
+    compressed and written.
+
+    Setting ``buffered=False`` will flush the output after each operation,
+    such as opening or closing an ``xf.element()`` block or calling
+    ``xf.write()``.  Alternatively, calling ``xf.flush()`` can be used to
+    explicitly flush any pending output when buffering is enabled.

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

+    # In the meantime, projects using versioned entry points will either have

+    by having an artificial ExtrasCandidate that wraps the "base" candidate.
+
+    The ExtrasCandidate differs from the base in the following ways:
+
+    1. It has a unique name, of the form foo[extra]. This causes the resolver

+    2. When we're getting the candidate's dependencies,
+       a) We specify that we want the extra dependencies as well.
+       b) We add a dependency on the base candidate.
+          See below for why this is needed.
+    3. We return None for the underlying InstallRequirement, as the base
+       candidate will provide it, and we don't want to end up with duplicates.
+
+    The dependency on the base candidate is needed so that the resolver can't
+    decide that it should recommend foo[extra1] version 1.0 and foo[extra2]
+    version 2.0. Having those candidates depend on foo=1.0 and foo=2.0

+    to the newly found leaves. The loop stops when no leaves are left: all

+    node twice (i.e. cycles). This is done through a depth-first search through
+    the graph, while keeping track of the path to the node.
+
+    Cycles in the graph result would result in node being revisited while also
+    being on its own path. In this case, take no action. This helps ensure we
+    don't get stuck in a cycle.

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

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

+    MessagePack Packer
+
+    Usage::
+
+        packer = Packer()
+        astream.write(packer.pack(a))
+        astream.write(packer.pack(b))
+
+    Packer's constructor has some keyword arguments:
+
+    :param callable default:
+        Convert user type to builtin type that Packer supports.
+        See also simplejson's document.
+
+    :param bool use_single_float:
+        Use single precision float type for float. (default: False)
+
+    :param bool autoreset:
+        Reset buffer after each pack and return its content as `bytes`. (default: True).
+        If set this to false, use `bytes()` to get content and `.reset()` to clear buffer.
+
+    :param bool use_bin_type:
+        Use bin type introduced in msgpack spec 2.0 for bytes.
+        It also enables str8 type for unicode. (default: True)
+
+    :param bool strict_types:
+        If set to true, types will be checked to be exact. Derived classes
+        from serializable types will not be serialized and will be
+        treated as unsupported type and forwarded to default.
+        Additionally tuples will not be serialized as lists.
+        This is useful when trying to implement accurate serialization
+        for python types.
+
+    :param bool datetime:
+        If set to true, datetime with tzinfo is packed into Timestamp type.
+        Note that the tzinfo is stripped in the timestamp.
+        You can get UTC datetime with `timestamp=3` option of the Unpacker.
+        (Python 2 is not supported).
+
+    :param str unicode_errors:
+        The error handler for encoding unicode. (default: 'strict')
+        DO NOT USE THIS!!  This option is kept for very specific usage.
+
+    Example of streaming deserialize from file-like object::
+
+        unpacker = Unpacker(file_like)
+        for o in unpacker:
+            process(o)
+
+    Example of streaming deserialize from socket::
+
+        unpacker = Unpacker()
+        while True:
+            buf = sock.recv(1024**2)
+            if not buf:
+                break
+            unpacker.feed(buf)
+            for o in unpacker:
+                process(o)
+
+    Raises ``ExtraData`` when *packed* contains extra bytes.
+    Raises ``OutOfData`` when *packed* is incomplete.
+    Raises ``FormatError`` when *packed* is not valid msgpack.
+    Raises ``StackError`` when *packed* contains too nested.
+    Other exceptions can be raised during unpacking.

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

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

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

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

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

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

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

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

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

+          an object with attributes if the given parser includes results names.
+
+        If the input string is required to match the entire grammar, ``parse_all`` flag must be set to ``True``. This

+
+        To report proper column numbers, ``parse_string`` operates on a copy of the input string where all tabs are
+        converted to spaces (8 spaces per tab, as per the default in ``string.expandtabs``). If the input string
+        contains tabs and the grammar uses parse actions that use the ``loc`` argument to index into the string

+
+        - calling ``parse_with_tabs`` on your grammar before calling ``parse_string`` (see :class:`parse_with_tabs`),
+        - define your parse action using the full ``(s,loc,toks)`` signature, and reference the input string using the
+          parse action's ``s`` argument, or
+        - explicitly expand the tabs in your input string before calling ``parse_string``.
+
+        Examples:

+
+        The parsing behavior varies by the inheriting class of this abstract class. Please refer to the children

+      match as a word; "ABC" will match "AAA", "ABAB", "CBAC", etc.;
+      if ``body_chars`` is also specified, then this is the string of
+      initial characters
+    - ``body_chars`` - string of characters that
+      can be used for matching after a matched initial character as
+      given in ``init_chars``; if omitted, same as the initial characters
+      (default=``None``)
+    - ``min`` - minimum number of characters to match (default=1)
+    - ``max`` - maximum number of characters to match (default=0)
+    - ``exact`` - exact number of characters to match (default=0)
+    - ``as_keyword`` - match as a keyword (default=``False``)
+    - ``exclude_chars`` - characters that might be

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

+        # - to *match* a specific recursion level, and

+        # and the two run concurrently. The *search* must *match* each recursion level
+        # to find the best possible match. This is handled by a memo table, which
+        # provides the previous match to the next level match attempt.
+        #

+    Helper method for defining space-delimited indentation blocks,

+

+
+    - ``blockStatementExpr`` - expression defining syntax of statement that
+      is repeated within the indented block
+    - ``indentStack`` - list created by caller to manage indentation stack
+      (multiple ``statementWithIndentedBlock`` expressions within a single

+    - ``indent`` - boolean indicating whether block must be indented beyond
+      the current level; set to ``False`` for block of left-most statements
+      (default= ``True``)
+
+    A valid block must contain at least one ``blockStatement``.

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

+           P = ParamSpec('P')
+
+        Parameter specification variables exist primarily for the benefit of static
+        type checkers.  They are used to forward the parameter types of one
+        callable to another callable, a pattern commonly found in higher order
+        functions and decorators.  They are only valid when used in ``Concatenate``,
+        or s the first argument to ``Callable``. In Python 3.10 and higher,
+        they are also supported in user-defined Generics at runtime.
+        See class Generic for more information on generic types.  An
+        example for annotating a decorator::
+
+           T = TypeVar('T')
+           P = ParamSpec('P')
+
+           def add_logging(f: Callable[P, T]) -> Callable[P, T]:

+        are yet to be decided.  See PEP 612 for details.
+
+        Parameter specification variables can be introspected. e.g.:
+
+           P.__name__ == 'T'
+           P.__bound__ == None
+           P.__covariant__ == False

+
+        ``TypeGuard`` aims to benefit *type narrowing* -- a technique used by static
+        type checkers to determine a more precise type of an expression within a
+        program's code flow.  Usually type narrowing is done by analyzing
+        conditional code flow and applying the narrowing to a block of code.  The
+        conditional expression here is sometimes referred to as a "type guard".
+
+        Sometimes it would be convenient to use a user-defined boolean function
+        as a type guard.  Such a function should use ``TypeGuard[...]`` as its
+        return type to alert static type checkers to this intention.
+
+        Using  ``-> TypeGuard`` tells the static type checker that for a given
+        function:
+
+        1. The return value is a boolean.
+        2. If the return value is ``True``, the type of its argument
+        is the type inside ``TypeGuard``.
+
+        For example::
+
+            def is_str(val: Union[str, float]):
+                # "isinstance" type guard
+                if isinstance(val, str):

+                else:
+                    # Else, type of ``val`` is narrowed to ``float``.
+                    ...
+
+        Strict type narrowing is not enforced -- ``TypeB`` need not be a narrower

+        At runtime, functions marked this way should return a boolean.
+
+        ``TypeGuard`` aims to benefit *type narrowing* -- a technique used by static
+        type checkers to determine a more precise type of an expression within a
+        program's code flow.  Usually type narrowing is done by analyzing
+        conditional code flow and applying the narrowing to a block of code.  The
+        conditional expression here is sometimes referred to as a "type guard".
+
+        Sometimes it would be convenient to use a user-defined boolean function
+        as a type guard.  Such a function should use ``TypeGuard[...]`` as its
+        return type to alert static type checkers to this intention.
+
+        Using  ``-> TypeGuard`` tells the static type checker that for a given
+        function:
+
+        1. The return value is a boolean.
+        2. If the return value is ``True``, the type of its argument
+        is the type inside ``TypeGuard``.
+
+        For example::
+
+            def is_str(val: Union[str, float]):
+                # "isinstance" type guard
+                if isinstance(val, str):
+                    # Type of ``val`` is narrowed to ``str``

+                else:
+                    # Else, type of ``val`` is narrowed to ``float``.
+                    ...
+
+        Strict type narrowing is not enforced -- ``TypeB`` need not be a narrower
+        form of ``TypeA`` (it can even be a wider form) and this may lead to
+        type-unsafe results.  The main reason is to allow for things like

+        In the same way that a normal type variable is a stand-in for a single
+        type such as ``int``, a type variable *tuple* is a stand-in for a *tuple*
+        type such as ``Tuple[int, str]``.
+
+        Type variable tuples can be used in ``Generic`` declarations.
+        Consider the following example::
+
+            class Array(Generic[*Ts]): ...
+
+        The ``Ts`` type variable tuple here behaves like ``tuple[T1, T2]``,
+        where ``T1`` and ``T2`` are type variables. To use these type variables
+        as type parameters of ``Array``, we must *unpack* the type variable tuple using
+        the star operator: ``*Ts``. The signature of ``Array`` then behaves
+        as if we had simply written ``class Array(Generic[T1, T2]): ...``.
+        In contrast to ``Generic[T1, T2]``, however, ``Generic[*Shape]`` allows
+        us to parameterise the class with an *arbitrary* number of type parameters.
+
+        Type variable tuples can be used anywhere a normal ``TypeVar`` can.
+        This includes class definitions, as shown above, as well as function
+        signatures and variable annotations::
+
+            class Array(Generic[*Ts]):
+

+        decorator. For example, the type checker will synthesize an ``__init__``
+        method.
+
+        The arguments to this decorator can be used to customize this behavior:
+        - ``eq_default`` indicates whether the ``eq`` parameter is assumed to be
+          True or False if it is omitted by the caller.
+        - ``order_default`` indicates whether the ``order`` parameter is
+          assumed to be True or False if it is omitted by the caller.
+        - ``kw_only_default`` indicates whether the ``kw_only`` parameter is
+          assumed to be True or False if it is omitted by the caller.
+        - ``field_specifiers`` specifies a static list of supported classes
+          or functions that describe fields, similar to ``dataclasses.field()``.
+
+        At runtime, this decorator records its arguments in the
+        ``__dataclass_transform__`` attribute on the decorated object.
+
+        See PEP 681 for details.

+            you read the entire contents of the response such as when
+            `preload_content=True`). This is useful if you're not preloading

+This module uses ctypes to bind a whole bunch of functions and constants from
+SecureTransport. The goal here is to provide the low-level API to
+SecureTransport. These are essentially the C-level functions and constants, and
+they're pretty gross to work with.

+
+There are `limitations <https://cloud.google.com/appengine/docs/python/\
+urlfetch/#Python_Quotas_and_limits>`_ to the URLFetch service and it may not be
+the best choice for your application. There are three options for using
+urllib3 on Google App Engine:
+
+1. You can use :class:`AppEngineManager` with URLFetch. URLFetch is
+   cost-effective in many circumstances as long as your usage is within the
+   limitations.
+2. You can use a normal :class:`~urllib3.PoolManager` by enabling sockets.
+   Sockets also have `limitations and restrictions
+   <https://cloud.google.com/appengine/docs/python/sockets/\
+   #limitations-and-restrictions>`_ and have a lower free quota than URLFetch.
+   To use sockets, be sure to specify the following in your ``app.yaml``::
+
+        env_variables:
+            GAE_USE_SOCKETS_HTTPLIB : 'true'
+
+3. If you are using `App Engine Flexible
+<https://cloud.google.com/appengine/docs/flexible/>`_, you can use the standard
+:class:`PoolManager` without any configuration or special environment variables.

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

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

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

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

+        How many connection-related errors to retry on.
+
+        These are errors raised before the request is sent to the remote server,

+
+        Set to ``0`` to fail on the first retry of this type.
+
+        If ``total`` is not set, it's a good idea to set this to 0 to account

+
+        By default, we only retry on methods which are considered to be

+
+    :param iterable status_forcelist:
+        A set of integer HTTP status codes that we should force a retry on.
+        A retry is initiated if the request method is in ``allowed_methods``
+        and the response status code is in ``status_forcelist``.
+
+        By default, this is disabled with ``None``.

+
+            {backoff factor} * (2 ** ({number of total retries} - 1))

+        seconds. If the backoff_factor is 0.1, then :func:`.sleep` will sleep
+        for [0.0s, 0.2s, 0.4s, ...] between retries. It will never be longer
+        than :attr:`Retry.DEFAULT_BACKOFF_MAX`.
+

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

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

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

+        "appname" is the name of application.
+            If None, just the system directory is returned.
+        "appauthor" (only used on Windows) is the name of the
+            appauthor or distributing body for this application. Typically
+            it is the owning company name. This falls back to appname. You may
+            pass False to disable it.
+        "version" is an optional version path element to append to the
+            path. You might want to use this if you want multiple versions
+            of your app to be able to run independently. If used, this
+            would typically be "<major>.<minor>".
+            Only applied when appname is present.
+        "opinion" (boolean) can be False to disable the appending of
+            "Logs" to the base app data dir for Windows, and "log" to the
+            base cache dir for Unix. See discussion below.
+
+    Typical user log directories are:
+        Mac OS X:   ~/Library/Logs/<AppName>
+        Unix:       ~/.cache/<AppName>/log  # or under $XDG_CACHE_HOME if defined

+        Vista:      C:\Users\<username>\AppData\Local\<AppAuthor>\<AppName>\Logs
+
+    On Windows the only suggestion in the MSDN docs is that local settings
+    go in the `CSIDL_LOCAL_APPDATA` directory. (Note: I'm interested in
+    examples of what some windows apps use for a logs dir.)
+
+    OPINION: This function appends "Logs" to the `CSIDL_LOCAL_APPDATA`
+    value for Windows and appends "log" to the user cache dir for Unix.
+    This can be disabled with the `opinion=False` option.

+"""For neatly implementing static typing in packaging.
+
+`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 packaging, all static-typing related imports should be guarded as follows:
+
+    from packaging._typing import TYPE_CHECKING
+
+    if TYPE_CHECKING:
+        from typing import ...

+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

+    
+    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

+    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}.

+     - L{alphas}
+     - L{nums}
+     - L{alphanums}
+     - L{hexnums}

+     - 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('(')})
+     - rpar - expression for matching right-parentheses (default=C{Suppress(')')})

+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+

+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including

+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

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

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

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

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

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

+    attributes of the Distribution instance.
+

+    'distutils.fancy_getopt'.  Any command-line options between the current
+    and the next command are used to set attributes of the current command

+Provides the CygwinCCompiler class, a subclass of UnixCCompiler that
+handles the Cygwin port of the GNU C compiler to Windows.  It also contains
+the Mingw32CCompiler class which handles the mingw32 port of GCC (same as
+cygwin in no-cygwin mode).

+# problems:
+#
+# * if you use a msvc compiled python version (1.5.2)
+#   1. you have to insert a __GNUC__ section in its config.h
+#   2. you have to generate an import library for its dll
+#      - create a def-file for python??.dll
+#      - create an import library using
+#             dlltool --dllname python15.dll --def python15.def \
+#                       --output-lib libpython15.a
+#
+#   see also http://starship.python.net/crew/kernr/mingw32/Notes.html
+#
+# * We put export_symbols in a def-file, and don't use
+#   --export-all-symbols because it doesn't worked reliable in some
+#   tested configurations. And because other windows compilers also
+#   need their symbols specified this no serious problem.
+#
+# tested configurations:
+#
+# * cygwin gcc 2.91.57/ld 2.9.4/dllwrap 0.2.4 works
+#   (after patching python's config.h and for C++ some other include files)
+#   see also http://starship.python.net/crew/kernr/mingw32/Notes.html
+# * mingw32 gcc 2.95.2/ld 2.9.4/dllwrap 0.2.4 works
+#   (ld doesn't support -shared, so we use dllwrap)
+# * cygwin gcc 2.95.2/ld 2.10.90/dllwrap 2.10.90 works now
+#   - its dllwrap doesn't work, there is a bug in binutils 2.10.90
+#     see also http://sources.redhat.com/ml/cygwin/2000-06/msg01274.html
+#   - using gcc -mdll instead dllwrap doesn't work without -static because
+#     it tries to link against dlls instead their import libraries. (If
+#     it finds the dll first.)
+#     By specifying -static we force ld to link against the import libraries,
+#     this is windows standard and there are normally not the necessary symbols
+#     in the dlls.
+#   *** only the version of June 2000 shows these problems
+# * cygwin gcc 3.2/ld 2.13.90 works
+#   (ld supports -shared)
+# * mingw gcc 3.2/ld 2.13 works
+#   (ld supports -shared)

+      extra_compile_args : [string]
+        any extra platform- and compiler-specific information to use
+        when compiling the source files in 'sources'.  For platforms and

+        extension language (i.e. "c", "c++", "objc"). Will be detected
+        from the source extensions if not provided.
+      optional : boolean
+        specifies that a build failure in the extension should not abort the
+        build process, but simply not install the failing extension.

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

+       Note that since 'rstrip_ws' can strip the trailing newline, the
+       semantics of 'readline()' must differ from those of the builtin file
+       object's 'readline()' method!  In particular, 'readline()' returns
+       None for end-of-file: an empty string might just be a blank line (or

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

+"""For neatly implementing static typing in packaging.
+
+`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 packaging, all static-typing related imports should be guarded as follows:
+
+    from packaging._typing import TYPE_CHECKING
+
+    if TYPE_CHECKING:
+        from typing import ...

+else:

+
+# typing's cast syntax requires calling typing.cast at runtime, but we don't
+# want to import typing at runtime. Here, we inform the type checkers that
+# we're importing `typing.cast` as `cast` and re-implement typing.cast's
+# runtime behavior in a block that is ignored by type checkers.

+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

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

+

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

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

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

+    Defined with string containing all allowed initial characters,

+    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.)

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

+

+
+        * You 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:

+
+    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

+    archive directory information. This, of course, assumes that the
+    replacement distribution is packaged as a zipped egg.
+

+    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

+    usage from here, and we clear only those that we know of and have found to

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

+
+Six is a Python 2 and 3 compatibility library.  It provides utility functions
+for smoothing over the differences between the Python versions with the goal of
+writing Python code that is compatible on both Python versions.  See the
+documentation for more information on what is provided.
+
+Six supports Python 2.7 and 3.3+.  It is contained in only one Python
+file, so it can be easily copied into your project. (The copyright and license
+notice must be retained.)
+
+Online documentation is at https://six.readthedocs.io/.
+
+Bugs can be reported to https://github.com/benjaminp/six.  The code can also
+be found there.

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

+            }
+
+        When uploading a file, providing a filename (the first parameter of the
+        tuple) is optional but recommended to best mimic behavior of browsers.
+
+        Note that if ``headers`` are supplied, the 'Content-Type' header will
+        be overwritten because it depends on the dynamic random boundary string
+        which is used to compose the body of the request. The random boundary

+"""
+Support for streaming http requests in emscripten.
+
+A few caveats -
+
+Firstly, you can't do streaming http in the main UI thread, because atomics.wait isn't allowed.
+Streaming only works if you're running pyodide in a web worker.
+
+Secondly, this uses an extra web worker and SharedArrayBuffer to do the asynchronous fetch
+operation, so it requires that you have crossOriginIsolation enabled, by serving over https
+(or from localhost) with the two headers below set:
+
+    Cross-Origin-Opener-Policy: same-origin
+    Cross-Origin-Embedder-Policy: require-corp
+
+You can tell if cross origin isolation is successfully enabled by looking at the global crossOriginIsolated variable in
+javascript console. If it isn't, streaming requests will fallback to XMLHttpRequest, i.e. getting the whole
+request into a buffer and then returning it. it shows a warning in the javascript console in this case.

+Finally, the webworker which does the streaming fetch is created on initial import, but will only be started once
+control is returned to javascript. Call `await wait_for_streaming_ready()` to wait for streaming fetch.
+
+NB: in this code, there are a lot of javascript objects. They are named js_*
+to make it clear what type of object they are.

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

+        pass

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

+
+    Each retry attempt will create a new Retry object with updated values, so
+    they can be safely reused.
+
+    Retries can be defined as a default for a pool:
+
+    .. code-block:: python
+
+        retries = Retry(connect=5, read=2, redirect=5)
+        http = PoolManager(retries=retries)
+        response = http.request("GET", "https://example.com/")
+
+    Or per-request (which overrides the default for the pool):
+
+    .. code-block:: python
+
+        response = http.request("GET", "https://example.com/", retries=Retry(10))
+
+    Retries can be disabled by passing ``False``:
+
+    .. code-block:: python
+
+        response = http.request("GET", "https://example.com/", retries=False)
+
+    Errors will be wrapped in :class:`~urllib3.exceptions.MaxRetryError` unless
+    retries are disabled, in which case the causing exception will be raised.
+
+    :param int total:
+        Total number of retries to allow. Takes precedence over other counts.
+
+        Set to ``None`` to remove this constraint and fall back on other
+        counts.
+
+        Set to ``0`` to fail on the first retry.
+
+        Set to ``False`` to disable and imply ``raise_on_redirect=False``.
+
+    :param int connect:
+        How many connection-related errors to retry on.
+
+        These are errors raised before the request is sent to the remote server,
+        which we assume has not triggered the server to process the request.
+
+        Set to ``0`` to fail on the first retry of this type.
+
+    :param int read:
+        How many times to retry on read errors.
+
+        These errors are raised after the request was sent to the server, so the
+        request may have side-effects.
+
+        Set to ``0`` to fail on the first retry of this type.
+
+    :param int redirect:
+        How many redirects to perform. Limit this to avoid infinite redirect
+        loops.
+
+        A redirect is a HTTP response with a status code 301, 302, 303, 307 or
+        308.
+
+        Set to ``0`` to fail on the first retry of this type.
+
+        Set to ``False`` to disable and imply ``raise_on_redirect=False``.
+
+    :param int status:
+        How many times to retry on bad status codes.
+
+        These are retries made on responses, where status code matches
+        ``status_forcelist``.
+
+        Set to ``0`` to fail on the first retry of this type.
+
+    :param int other:
+        How many times to retry on other errors.
+
+        Other errors are errors that are not connect, read, redirect or status errors.
+        These errors might be raised after the request was sent to the server, so the
+        request might have side-effects.
+
+        Set to ``0`` to fail on the first retry of this type.
+
+        If ``total`` is not set, it's a good idea to set this to 0 to account
+        for unexpected edge cases and avoid infinite retry loops.
+
+    :param Collection allowed_methods:
+        Set of uppercased HTTP method verbs that we should retry on.
+
+        By default, we only retry on methods which are considered to be
+        idempotent (multiple requests with the same parameters end with the
+        same state). See :attr:`Retry.DEFAULT_ALLOWED_METHODS`.
+
+        Set to a ``None`` value to retry on any verb.
+
+    :param Collection status_forcelist:
+        A set of integer HTTP status codes that we should force a retry on.
+        A retry is initiated if the request method is in ``allowed_methods``
+        and the response status code is in ``status_forcelist``.
+
+        By default, this is disabled with ``None``.
+
+    :param float backoff_factor:
+        A backoff factor to apply between attempts after the second try
+        (most errors are resolved immediately by a second try without a
+        delay). urllib3 will sleep for::
+
+            {backoff factor} * (2 ** ({number of previous retries}))
+
+        seconds. If `backoff_jitter` is non-zero, this sleep is extended by::
+
+            random.uniform(0, {backoff jitter})
+
+        seconds. For example, if the backoff_factor is 0.1, then :func:`Retry.sleep` will
+        sleep for [0.0s, 0.2s, 0.4s, 0.8s, ...] between retries. No backoff will ever
+        be longer than `backoff_max`.
+
+        By default, backoff is disabled (factor set to 0).
+
+    :param bool raise_on_redirect: Whether, if the number of redirects is
+        exhausted, to raise a MaxRetryError, or to return a response with a
+        response code in the 3xx range.
+
+    :param bool raise_on_status: Similar meaning to ``raise_on_redirect``:
+        whether we should raise an exception, or return a response,
+        if status falls in ``status_forcelist`` range and retries have
+        been exhausted.
+
+    :param tuple history: The history of the request encountered during
+        each call to :meth:`~Retry.increment`. The list is in the order
+        the requests occurred. Each list item is of class :class:`RequestHistory`.
+
+    :param bool respect_retry_after_header:
+        Whether to respect Retry-After header on status codes defined as
+        :attr:`Retry.RETRY_AFTER_STATUS_CODES` or not.
+
+    :param Collection remove_headers_on_redirect:
+        Sequence of headers to remove from the request when a response
+        indicating a redirect is returned before firing off the redirected
+        request.

+        This combines the connect and read timeouts into one; the read timeout

+        event that both a connect timeout and a total are specified, or a read
+        timeout and a total are specified, the shorter timeout will be applied.

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

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