+# Instantiator
+
+This library provides a way of avoiding usage of constructors when instantiating PHP classes.

+[![Latest Unstable Version](https://poser.pugx.org/doctrine/instantiator/v/unstable.png)](https://packagist.org/packages/doctrine/instantiator)
+
+## Installation
+
+The suggested installation method is via [composer](https://getcomposer.org/):
+
+```sh
+php composer.phar require "doctrine/instantiator:~1.0.3"
+```
+
+## Usage
+
+The instantiator is able to create new instances of any class without using the constructor or any API of the class
+itself:
+
+```php
+$instantiator = new \Doctrine\Instantiator\Instantiator();
+
+$instance = $instantiator->instantiate(\My\ClassName\Here::class);
+```
+
+## Contributing
+
+Please read the [CONTRIBUTING.md](CONTRIBUTING.md) contents if you wish to help out!
+
+## Credits
+
+This library was migrated from [ocramius/instantiator](https://github.com/Ocramius/Instantiator), which
+has been donated to the doctrine organization, and which is now deprecated in favour of this package.

+# Contributions are welcome!
+
+## Quick guide
+
+ * Fork the repo.
+ * Checkout the branch you want to make changes on:
+  * Master if you make changes to the code that are not backward compatible.
+  * Default branch when adding new features.
+  * Branch before the default if you are fixing a bug for an existing feature (or the default/master branch if the feature was introduced in that version).
+ * Install dependencies: `composer install`.
+ * Create branch, e.g. `feature-foo` or `bugfix-bar`.
+ * Make changes.
+ * If you are adding functionality or fixing a bug - add a test!
+ * Fix project itself: `php php-cs-fixer fix`.
+ * Regenerate readme: `php php-cs-fixer readme > README.rst`. Do not modify `README.rst` manually!
+ * Check if tests pass: `phpunit` [(4.x or 5.x)](https://phpunit.de/manual/current/en/installation.html)
+
+## Opening a pull request
+
+You can do some things to increase the chance that your pull request is accepted the first time:
+
+ * Submit one pull request per fix or feature.
+ * If your changes are not up to date - rebase your branch on the parent branch.
+ * Follow the conventions used in the project.
+ * Remember about tests and documentation.
+ * Don't bump version.
+
+## Making new fixers
+
+There is a [cookbook](https://github.com/FriendsOfPHP/PHP-CS-Fixer/blob/master/COOKBOOK-FIXERS.md) with basic instructions on how to build a new fixer. Consider reading it
+before opening a PR.

+Cookbook - Making a new Fixer for PHP CS Fixer
+==============================================
+
+You want to make a new fixer to PHP CS Fixer and do not know how to
+start. Follow this document and you will be able to do it.
+
+## Background
+
+In order to be able to create a new fixer, you need some background.
+PHP CS Fixer is a transcompiler which takes valid PHP code and pretty
+print valid PHP code. It does all transformations in multiple passes,
+a.k.a., multi-pass compiler.
+
+Therefore, a new fixer is meant to be ideally
+[idempotent](http://en.wikipedia.org/wiki/Idempotence#Computer_science_meaning),
+or at least atomic in its actions. More on this later.
+
+All contributions go through a code review process. Do not feel
+discouraged - it is meant only to give more people more chance to
+contribute, and to detect bugs ([Linus'
+Law](http://en.wikipedia.org/wiki/Linus%27s_Law)).
+
+If possible, try to get acquainted with the public interface for the
+[Tokens class](Symfony/CS/Tokenizer/Tokens.php)
+and [Token class](Symfony/CS/Tokenizer/Token.php)
+classes.
+
+## Assumptions
+
+* You are familiar with Test Driven Development.
+* Forked FriendsOfPHP/PHP-CS-Fixer into your own Github Account.
+* Cloned your forked repository locally.
+* Installed the dependencies of PHP CS Fixer using [Composer](https://getcomposer.org/).
+* You have read [`CONTRIBUTING.md`](CONTRIBUTING.md).
+
+## Step by step
+
+For this step-by-step, we are going to create a simple fixer that
+removes all comments of the code that are preceded by ';' (semicolon).
+
+We are calling it `remove_comments` (code name), or,
+`RemoveCommentsFixer` (class name).
+
+### Step 1 - Creating files
+
+Create a new file in
+`PHP-CS-Fixer/Symfony/CS/Fixer/Contrib/RemoveCommentsFixer.php`.
+Put this content inside:
+```php
+<?php
+
+/*
+ * This file is part of the PHP CS utility.
+ *
+ * (c) Fabien Potencier <fabien@symfony.com>
+ *
+ * This source file is subject to the MIT license that is bundled
+ * with this source code in the file LICENSE.
+ */
+
+namespace Symfony\CS\Fixer\Contrib;
+
+use Symfony\CS\AbstractFixer;
+use Symfony\CS\Tokenizer\Tokens;
+
+/**
+ * @author Your name <your@email.com>
+ */
+final class RemoveCommentsFixer extends AbstractFixer
+{
+    /**
+     * {@inheritdoc}
+     */
+    public function fix(\SplFileInfo $file, $content)
+    {
+        // Add the fixing logic of the fixer here.
+    }
+
+    /**
+     * {@inheritdoc}
+     */
+    public function getDescription()
+    {
+        // Return a short description of the Fixer, it will be used in the README.rst.
+    }
+}
+```
+
+Note how the class and file name match. Also keep in mind that all
+fixers must implement `FixerInterface`. In this case, the fixer is
+inheriting from `AbstractFixer`, which fulfills the interface with some
+default behavior.
+
+Now let us create the test file at
+`Symfony/CS/Tests/Fixer/Contrib/RemoveCommentsFixerTest.php` . Put this
+content inside:
+
+```php
+<?php
+
+/*
+ * This file is part of the PHP CS utility.
+ *
+ * (c) Fabien Potencier <fabien@symfony.com>
+ *
+ * This source file is subject to the MIT license that is bundled
+ * with this source code in the file LICENSE.
+ */
+
+namespace Symfony\CS\Tests\Fixer\Contrib;
+
+use Symfony\CS\Tests\Fixer\AbstractFixerTestBase;

+{
+    /**
+     * @dataProvider provideFixCases
+     */
+    public function testFix($expected, $input = null)
+    {
+        $this->makeTest($expected, $input);

+
+    public function provideFixCases()

+```
+
+The files are created, one thing is still missing though: we need to
+update the README.md. Fortunately, PHP CS Fixer can help you here.
+Execute the following command in your command shell:
+
+`$ php php-cs-fixer readme > README.rst`
+
+### Step 2 - Using tests to define fixers behavior
+
+Now that the files are created, you can start writing test to define the
+behavior of the fixer. You have to do it in two ways: first, ensuring
+the fixer changes what it should be changing; second, ensuring that
+fixer does not change what is not supposed to change. Thus:
+
+#### Keeping things as they are:
+`Symfony/CS/Tests/Fixer/Contrib/RemoveCommentsFixerTest.php`@provideFixCases:
+```php
+    ...
+    public function provideFixCases()
+    {
+    	return array(
+    		array('<?php echo "This should not be changed";') // Each sub-array is a test
+    	);
+    }
+    ...
+```
+
+#### Ensuring things change:
+`Symfony/CS/Tests/Fixer/Contrib/RemoveCommentsFixerTest.php`@provideFixCases:
+```php
+    ...
+    public function provideFixCases()
+    {
+    	return array(
+    		array(
+    			'<?php echo "This should be changed"; ', // This is expected output
+    			'<?php echo "This should be changed"; /* Comment */', // This is input
+    		)
+    	);
+    }
+    ...
+```
+
+Note that expected outputs are **always** tested alone to ensure your fixer will not change it.
+
+We want to have a failing test to start with, so the test file now looks
+like:
+`Symfony/CS/Tests/Fixer/Contrib/RemoveCommentsFixerTest.php`
+```php
+<?php
+
+/*

+ * with this source code in the file LICENSE.
+ */
+
+namespace Symfony\CS\Tests\Fixer\Contrib;
+
+use Symfony\CS\Tests\Fixer\AbstractFixerTestBase;
+
+/**
+ * @author Your name <your@email.com>
+ *
+ * @internal
+ */
+final class RemoveCommentsFixerTest extends AbstractFixerTestBase
+{
+    /**
+     * @dataProvider provideFixCases
+     */
+    public function testFix($expected, $input = null)
+    {
+        $this->makeTest($expected, $input);
+    }
+
+    public function provideFixCases()
+    {
+        return array(
+            array(
+               '<?php echo "This should be changed"; ', // This is expected output
+               '<?php echo "This should be changed"; /* Comment */', // This is input
+            )
+        );
+    }
+}
+```
+
+
+### Step 3 - Implement your solution
+
+You have defined the behavior of your fixer in tests. Now it is time to
+implement it.
+
+We need first to create one method to describe what this fixer does:
+`Symfony/CS/Fixer/Contrib/RemoveCommentsFixer.php`:
+```php
+final class RemoveCommentsFixer extends AbstractFixer
+{
+    ...
+    /**
+     * {@inheritdoc}
+     */
+    public function getDescription()
+    {
+        return 'Removes all comments of the code that are preceded by ";" (semicolon).'; // Trailing dot is important. We thrive to use English grammar properly.
+    }
+}
+```
+
+For now, let us just make a fixer that applies no modification:
+`Symfony/CS/Fixer/Contrib/RemoveCommentsFixer.php`:
+```php
+final class RemoveCommentsFixer extends AbstractFixer
+{
+    /**
+     * {@inheritdoc}
+     */
+    public function fix(\SplFileInfo $file, $content)
+    {
+        $tokens = Tokens::fromCode($content);
+
+        return $tokens->generateCode();
+    }
+}
+```
+
+Run `$ phpunit Symfony/CS/Tests/Fixer/Contrib/RemoveCommentsFixerTest.php`.
+You are going to see that the tests fails.
+
+### Break
+Now we have pretty much a cradle to work with. A file with a failing
+test, and the fixer, that for now does not do anything.
+
+How do fixers work? In the PHP CS Fixer, they work by iterating through
+pieces of codes (each being a Token), and inspecting what exists before
+and after that bit and making a decision, usually:
+
+ * Adding code.
+ * Modifying code.
+ * Deleting code.
+ * Ignoring code.
+
+In our case, we want to find all comments, and foreach (pun intended)
+one of them check if they are preceded by a semicolon symbol.
+
+Now you need to do some reading, because all these symbols obey a list
+defined by the PHP compiler. It is the ["List of Parser
+Tokens"](http://php.net/manual/en/tokens.php).
+
+Internally, PHP CS Fixer transforms some of PHP native tokens into custom
+tokens through the use of [Transfomers](Symfony/CS/Tokenizer/Transformer),
+they aim to help you reason about the changes you may want to do in the
+fixers.
+
+So we can get to move forward, humor me in believing that comments have
+one symbol name: `T_COMMENT`.
+
+### Step 3 - Implement your solution - continuation.
+
+We do not want all symbols to be analysed. Only `T_COMMENT`. So let us
+iterate the token(s) we are interested in.
+`Symfony/CS/Fixer/Contrib/RemoveCommentsFixer.php`:
+```php
+final class RemoveCommentsFixer extends AbstractFixer
+{
+    /**
+     * {@inheritdoc}
+     */
+    public function fix(\SplFileInfo $file, $content)
+    {
+        $tokens = Tokens::fromCode($content);
+
+        $foundComments = $tokens->findGivenKind(T_COMMENT);
+        foreach($foundComments as $index => $token){
+
+        }
+
+        return $tokens->generateCode();
+    }
+}
+```
+
+OK, now for each `T_COMMENT`, all we need to do is check if the previous
+token is a semicolon.
+`Symfony/CS/Fixer/Contrib/RemoveCommentsFixer.php`:
+```php
+final class RemoveCommentsFixer extends AbstractFixer
+{
+    /**
+     * {@inheritdoc}
+     */
+    public function fix(\SplFileInfo $file, $content)
+    {
+        $tokens = Tokens::fromCode($content);
+
+        $foundComments = $tokens->findGivenKind(T_COMMENT);
+        foreach($foundComments as $index => $token){
+            $prevTokenIndex = $tokens->getPrevMeaningfulToken($index);
+            $prevToken = $tokens[$prevTokenIndex];
+
+            if($prevToken->equals(';')){
+                $token->clear();
+            }
+        }
+
+        return $tokens->generateCode();
+    }
+}
+```
+
+So the fixer in the end looks like this:
+```php
+<?php
+
+/*
+ * This file is part of the PHP CS utility.
+ *
+ * (c) Fabien Potencier <fabien@symfony.com>
+ *
+ * This source file is subject to the MIT license that is bundled
+ * with this source code in the file LICENSE.
+ *
+ */
+
+namespace Symfony\CS\Fixer\Contrib;
+
+use Symfony\CS\AbstractFixer;
+use Symfony\CS\Tokenizer\Tokens;
+
+/**
+ * @author Your name <your@email.com>
+ */
+final class RemoveCommentsFixer extends AbstractFixer {
+    /**
+     * {@inheritdoc}
+     */
+    public function fix(\SplFileInfo $file, $content) {
+        $tokens = Tokens::fromCode($content);
+
+        $foundComments = $tokens->findGivenKind(T_COMMENT);
+        foreach ($foundComments as $index => $token) {
+            $prevTokenIndex = $tokens->getPrevMeaningfulToken($index);
+            $prevToken = $tokens[$prevTokenIndex];
+
+            if ($prevToken->equals(';')) {
+                $token->clear();
+            }
+        }
+
+        return $tokens->generateCode();
+    }
+
+    /**
+     * {@inheritdoc}
+     */
+    public function getDescription() {
+        return 'Removes all comments of the code that are preceded by ";" (semicolon).';// Trailing dot is important. We thrive to use English grammar properly.
+    }
+}
+```
+
+### Step 4 - Format, Commit, PR.
+
+Note that so far, we have not coded adhering to PSR-1/2. This is done on
+purpose. For every commit you make, you must use PHP CS Fixer to fix
+itself. Thus, on the command line call:
+
+`$ php php-cs-fixer fix`
+
+This will fix all the coding style mistakes.
+
+After the final CS fix, you are ready to commit. Do it.
+
+Now, go to Github and open a Pull Request.
+
+
+### Step 5 - Peer review: it is all about code and community building.
+
+Congratulations, you have made your first fixer. Be proud. Your work
+will be reviewed carefully by PHP CS Fixer community.
+
+The review usually flows like this:
+
+1. People will check your code for common mistakes and logical
+caveats. Usually, the person building a fixer is blind about some
+behavior mistakes of fixers. Expect to write few more tests to cater for
+the reviews.
+2. People will discuss the relevance of your fixer. If it is
+something that goes along with Symfony style standards, or PSR-1/PSR-2
+standards, they will ask you to move from Symfony/CS/Fixers/Contrib to
+Symfony/CS/Fixers/{Symfony, PSR2, etc}.
+3. People will also discuss whether your fixer is idempotent or not.
+If they understand that your fixer must always run before or after a
+certain fixer, they will ask you to override a method named
+`getPriority()`. Do not be afraid of asking the reviewer for help on how
+to do it.
+4. People may ask you to rebase your code to unify commits or to get
+rid of merge commits.
+5. Go to 1 until no actions are needed anymore.
+
+Your fixer will be incorporated in the next release.
+
+# Congratulations! You have done it.
+
+
+
+## Q&A
+
+#### Why is not my PR merged yet?
+
+PHP CS Fixer is used by many people, that expect it to be stable. So
+sometimes, few PR are delayed a bit so to avoid cluttering at @dev
+channel on composer.
+
+Other possibility is that reviewers are giving time to other members of
+PHP CS Fixer community to partake on the review debates of your fixer.
+
+In any case, we care a lot about what you do and we want to see it being
+part of the application as soon as possible.
+
+#### May I use short arrays (`$a = []`)?
+
+No. Short arrays were introduced in PHP 5.4 and PHP CS Fixer still
+supports PHP 5.3.6.
+
+#### Why are you steering me to create my fixer at CONTRIB_LEVEL ?
+
+CONTRIB_LEVEL is the most lax level - and it is far more likely to have
+your fixer accepted at CONTRIB_LEVEL and later changed to SYMFOMY_LEVEL
+or PSR2_LEVEL; than the other way around.
+
+If you make your contribution directly at PSR2_LEVEL, eventually the
+relevance debate will take place and your fixer might be pushed to
+CONTRIB_LEVEL.
+
+#### Why am I asked to use `getPrevMeaningfulToken()` instead of `getPrevNonWhitespace()`?
+
+The main difference is that `getPrevNonWhitespace()` ignores only
+whitespaces (`T_WHITESPACE`), while `getPrevMeaningfulToken()` ignores
+whitespaces and comments. And usually that is what you want. For
+example:
+
+```php
+$a->/*comment*/func();
+```
+
+If you are inspecting `func()`, and you want to check whether this is
+part of an object, if you use `getPrevNonWhitespace()` you are going to
+get `/*comment*/`, which might belie your test. On the other hand, if
+you use `getPrevMeaningfulToken()`, no matter if you have got a comment
+or a whitespace, the returned token will always be `->`.

+PHP Coding Standards Fixer
+==========================
+
+The PHP Coding Standards Fixer tool fixes *most* issues in your code when you
+want to follow the PHP coding standards as defined in the PSR-1 and PSR-2
+documents and many more.
+
+If you are already using a linter to identify coding standards problems in your
+code, you know that fixing them by hand is tedious, especially on large
+projects. This tool does not only detect them, but also fixes them for you.
+
+Requirements
+------------
+
+PHP needs to be a minimum version of PHP 5.3.6.
+
+Installation
+------------
+
+Locally
+~~~~~~~
+
+Download the `php-cs-fixer.phar`_ file and store it somewhere on your computer.
+
+Globally (manual)
+~~~~~~~~~~~~~~~~~
+
+You can run these commands to easily access ``php-cs-fixer`` from anywhere on
+your system:
+
+.. code-block:: bash
+
+    $ wget https://github.com/FriendsOfPHP/PHP-CS-Fixer/releases/download/v1.13.3/php-cs-fixer.phar -O php-cs-fixer
+
+or with curl:
+
+.. code-block:: bash
+
+    $ curl -L https://github.com/FriendsOfPHP/PHP-CS-Fixer/releases/download/v1.13.3/php-cs-fixer.phar -o php-cs-fixer
+
+then:
+
+.. code-block:: bash
+
+    $ sudo chmod a+x php-cs-fixer
+    $ sudo mv php-cs-fixer /usr/local/bin/php-cs-fixer
+
+Then, just run ``php-cs-fixer``.
+
+Globally (Composer)
+~~~~~~~~~~~~~~~~~~~
+
+To install PHP CS Fixer, install Composer and issue the following command:
+
+.. code-block:: bash
+
+    $ ./composer.phar global require friendsofphp/php-cs-fixer
+
+Please be aware that before v1.12 package name was different:
+
+.. code-block:: bash
+
+    $ ./composer.phar global require fabpot/php-cs-fixer
+
+Then make sure you have ``~/.composer/vendor/bin`` in your ``PATH`` and
+you're good to go:
+
+.. code-block:: bash
+
+    $ export PATH="$PATH:$HOME/.composer/vendor/bin"
+
+Globally (homebrew)
+~~~~~~~~~~~~~~~~~~~
+
+PHP-CS-Fixer is part of the homebrew-php project. Follow the installation
+instructions at https://github.com/homebrew/homebrew-php if you don't
+already have it.
+
+.. code-block:: bash
+
+    $ brew install homebrew/php/php-cs-fixer
+
+Update
+------
+
+Locally
+~~~~~~~
+
+The ``self-update`` command tries to update ``php-cs-fixer`` itself:
+
+.. code-block:: bash
+
+    $ php php-cs-fixer.phar self-update
+
+Globally (manual)
+~~~~~~~~~~~~~~~~~
+
+You can update ``php-cs-fixer`` through this command:
+
+.. code-block:: bash
+
+    $ sudo php-cs-fixer self-update
+
+Globally (Composer)
+~~~~~~~~~~~~~~~~~~~
+
+You can update ``php-cs-fixer`` through this command:
+
+.. code-block:: bash
+
+    $ ./composer.phar global update friendsofphp/php-cs-fixer
+
+Globally (homebrew)
+~~~~~~~~~~~~~~~~~~~
+
+You can update ``php-cs-fixer`` through this command:
+
+.. code-block:: bash
+
+    $ brew upgrade php-cs-fixer
+
+Usage
+-----
+
+The ``fix`` command tries to fix as much coding standards
+problems as possible on a given file or files in a given directory and its subdirectories:
+
+.. code-block:: bash
+
+    $ php php-cs-fixer.phar fix /path/to/dir
+    $ php php-cs-fixer.phar fix /path/to/file
+
+The ``--format`` option for the output format. Supported formats are ``txt`` (default one), ``json`` and ``xml``.
+
+The ``--verbose`` option will show the applied fixers. When using the ``txt`` format it will also displays progress notifications.
+
+The ``--level`` option limits the fixers to apply on the
+project:
+
+.. code-block:: bash
+
+    $ php php-cs-fixer.phar fix /path/to/project --level=psr0
+    $ php php-cs-fixer.phar fix /path/to/project --level=psr1
+    $ php php-cs-fixer.phar fix /path/to/project --level=psr2
+    $ php php-cs-fixer.phar fix /path/to/project --level=symfony
+
+By default, all PSR-2 fixers and some additional ones are run. The "contrib
+level" fixers cannot be enabled via this option; you should instead set them
+manually by their name via the ``--fixers`` option.
+
+The ``--fixers`` option lets you choose the exact fixers to
+apply (the fixer names must be separated by a comma):
+
+.. code-block:: bash
+
+    $ php php-cs-fixer.phar fix /path/to/dir --fixers=linefeed,short_tag,indentation
+
+You can also blacklist the fixers you don't want by placing a dash in front of the fixer name, if this is more convenient,
+using ``-name_of_fixer``:
+
+.. code-block:: bash
+
+    $ php php-cs-fixer.phar fix /path/to/dir --fixers=-short_tag,-indentation
+
+When using combination with exact and blacklist fixers, apply exact fixers along with above blacklisted result:
+
+.. code-block:: bash
+
+    $ php php-cs-fixer.phar fix /path/to/dir --fixers=linefeed,-short_tag
+
+A combination of ``--dry-run`` and ``--diff`` will
+display summary of proposed fixes, leaving your files unchanged.
+
+The command can also read from standard input, in which case it won't
+automatically fix anything:
+
+.. code-block:: bash
+
+    $ cat foo.php | php php-cs-fixer.phar fix --diff -
+
+Choose from the list of available fixers:

+
+
+The ``--config`` option customizes the files to analyse, based
+on some well-known directory structures:
+
+.. code-block:: bash
+
+    # For the Symfony 2.3+ branch
+    $ php php-cs-fixer.phar fix /path/to/sf23 --config=sf23
+
+Choose from the list of available configurations:
+
+* **default** A default configuration
+
+* **magento** The configuration for a Magento application
+
+* **sf23**    The configuration for the Symfony 2.3+ branch
+
+The ``--dry-run`` option displays the files that need to be
+fixed but without actually modifying them:
+
+.. code-block:: bash
+
+    $ php php-cs-fixer.phar fix /path/to/code --dry-run
+
+Instead of using command line options to customize the fixer, you can save the
+configuration in a ``.php_cs`` file in the root directory of
+your project. The file must return an instance of
+``Symfony\CS\ConfigInterface``, which lets you configure the fixers, the level, the files,
+and directories that need to be analyzed. The example below will add two contrib fixers
+to the default list of symfony-level fixers:
+
+.. code-block:: php
+
+    <?php
+
+    $finder = Symfony\CS\Finder::create()
+        ->exclude('somedir')
+        ->notPath('src/Symfony/Component/Translation/Tests/fixtures/resources.php')
+        ->in(__DIR__)
+    ;
+
+    return Symfony\CS\Config::create()
+        ->fixers(array('strict_param', 'short_array_syntax'))
+        ->finder($finder)
+    ;
+
+**NOTE**: ``exclude`` will work only for directories, so if you need to exclude file, try ``notPath``.
+
+See `Symfony\\Finder <http://symfony.com/doc/current/components/finder.html>`_
+online documentation for other `Finder` methods.
+
+If you want complete control over which fixers you use, you may use the empty level and
+then specify all fixers to be used:
+
+.. code-block:: php
+
+    <?php
+
+    $finder = Symfony\CS\Finder::create()
+        ->in(__DIR__)
+    ;
+
+    return Symfony\CS\Config::create()
+        ->level(Symfony\CS\FixerInterface::NONE_LEVEL)
+        ->fixers(array('trailing_spaces', 'encoding'))
+        ->finder($finder)
+    ;
+
+You may also use a blacklist for the Fixers instead of the above shown whitelist approach.
+The following example shows how to use all ``symfony`` Fixers but the ``psr0`` fixer.
+Note the additional ``-`` in front of the Fixer name.
+
+.. code-block:: php
+
+    <?php
+
+    $finder = Symfony\CS\Finder::create()
+        ->exclude('somedir')
+        ->in(__DIR__)
+    ;
+
+    return Symfony\CS\Config::create()
+        ->fixers(array('-psr0'))
+        ->finder($finder)
+    ;
+
+The ``symfony`` level is set by default, you can also change the default level:
+
+.. code-block:: php
+
+    <?php
+
+    return Symfony\CS\Config::create()
+        ->level(Symfony\CS\FixerInterface::PSR2_LEVEL)
+    ;
+
+In combination with these config and command line options, you can choose various usage.
+
+For example, default level is ``symfony``, but if you also don't want to use
+the ``psr0`` fixer, you can specify the ``--fixers="-psr0"`` option.
+
+But if you use the ``--fixers`` option with only exact fixers,
+only those exact fixers are enabled whether or not level is set.
+
+With the ``--config-file`` option you can specify the path to the
+``.php_cs`` file.
+
+Caching
+-------
+
+You can enable caching by returning a custom config with caching enabled. This will
+speed up further runs.
+
+.. code-block:: php
+
+    <?php
+
+    return Symfony\CS\Config::create()
+        ->setUsingCache(true)
+    ;
+
+Exit codes
+----------
+*  0 OK.
+*  1 Changes made (or dry-run was used and files need changes) or PHP/HHVM minimal requirement to run the Fixer not match.
+* 16 Configuration error of the application.
+* 32 Configuration error of a Fixer.
+
+(applies to exit codes of the `fix` command only)
+
+Helpers
+-------
+
+Dedicated plugins exist for:
+
+* `Atom`_
+* `NetBeans`_
+* `PhpStorm`_
+* `Sublime Text`_
+* `Vim`_
+
+Contribute
+----------
+
+The tool comes with quite a few built-in fixers and finders, but everyone is
+more than welcome to `contribute`_ more of them.
+
+Fixers
+~~~~~~
+
+A *fixer* is a class that tries to fix one CS issue (a ``Fixer`` class must
+implement ``FixerInterface``).
+
+Configs
+~~~~~~~
+
+A *config* knows about the CS level and the files and directories that must be
+scanned by the tool when run in the directory of your project. It is useful for
+projects that follow a well-known directory structures (like for Symfony
+projects for instance).

+The <info>%command.name%</info> command tries to fix as much coding standards
+problems as possible on a given file or files in a given directory and its subdirectories:
+
+    <info>$ php %command.full_name% /path/to/dir</info>
+    <info>$ php %command.full_name% /path/to/file</info>
+
+The <comment>--format</comment> option for the output format. Supported formats are ``txt`` (default one), ``json`` and ``xml``.
+
+The <comment>--verbose</comment> option will show the applied fixers. When using the ``txt`` format it will also displays progress notifications.
+
+The <comment>--level</comment> option limits the fixers to apply on the
+project:
+
+    <info>$ php %command.full_name% /path/to/project --level=psr0</info>
+    <info>$ php %command.full_name% /path/to/project --level=psr1</info>
+    <info>$ php %command.full_name% /path/to/project --level=psr2</info>
+    <info>$ php %command.full_name% /path/to/project --level=symfony</info>
+
+By default, all PSR-2 fixers and some additional ones are run. The "contrib
+level" fixers cannot be enabled via this option; you should instead set them
+manually by their name via the <comment>--fixers</comment> option.
+
+The <comment>--fixers</comment> option lets you choose the exact fixers to
+apply (the fixer names must be separated by a comma):
+
+    <info>$ php %command.full_name% /path/to/dir --fixers=linefeed,short_tag,indentation</info>
+
+You can also blacklist the fixers you don't want by placing a dash in front of the fixer name, if this is more convenient,
+using <comment>-name_of_fixer</comment>:
+
+    <info>$ php %command.full_name% /path/to/dir --fixers=-short_tag,-indentation</info>
+
+When using combination with exact and blacklist fixers, apply exact fixers along with above blacklisted result:
+
+    <info>$ php php-cs-fixer.phar fix /path/to/dir --fixers=linefeed,-short_tag</info>
+
+A combination of <comment>--dry-run</comment> and <comment>--diff</comment> will
+display summary of proposed fixes, leaving your files unchanged.
+
+The command can also read from standard input, in which case it won't
+automatically fix anything:
+
+    <info>$ cat foo.php | php %command.full_name% --diff -</info>
+
+Choose from the list of available fixers:
+
+{$this->getFixersHelp()}
+
+The <comment>--config</comment> option customizes the files to analyse, based
+on some well-known directory structures:
+
+    <comment># For the Symfony 2.3+ branch</comment>
+    <info>$ php %command.full_name% /path/to/sf23 --config=sf23</info>
+
+Choose from the list of available configurations:
+
+{$this->getConfigsHelp()}
+The <comment>--dry-run</comment> option displays the files that need to be
+fixed but without actually modifying them:
+
+    <info>$ php %command.full_name% /path/to/code --dry-run</info>
+
+Instead of using command line options to customize the fixer, you can save the
+configuration in a <comment>.php_cs</comment> file in the root directory of
+your project. The file must return an instance of
+``Symfony\CS\ConfigInterface``, which lets you configure the fixers, the level, the files,
+and directories that need to be analyzed. The example below will add two contrib fixers
+to the default list of symfony-level fixers:
+
+    <?php
+
+    \$finder = Symfony\CS\Finder::create()
+        ->exclude('somedir')
+        ->notPath('src/Symfony/Component/Translation/Tests/fixtures/resources.php')
+        ->in(__DIR__)
+    ;
+
+    return Symfony\CS\Config::create()
+        ->fixers(array('strict_param', 'short_array_syntax'))
+        ->finder(\$finder)
+    ;
+
+    ?>
+
+**NOTE**: ``exclude`` will work only for directories, so if you need to exclude file, try ``notPath``.
+
+See `Symfony\\\\Finder <http://symfony.com/doc/current/components/finder.html>`_
+online documentation for other `Finder` methods.
+
+If you want complete control over which fixers you use, you may use the empty level and
+then specify all fixers to be used:
+
+    <?php
+
+    \$finder = Symfony\CS\Finder::create()
+        ->in(__DIR__)
+    ;
+
+    return Symfony\CS\Config::create()
+        ->level(Symfony\CS\FixerInterface::NONE_LEVEL)
+        ->fixers(array('trailing_spaces', 'encoding'))
+        ->finder(\$finder)
+    ;
+
+    ?>
+
+You may also use a blacklist for the Fixers instead of the above shown whitelist approach.
+The following example shows how to use all ``symfony`` Fixers but the ``psr0`` fixer.
+Note the additional <comment>-</comment> in front of the Fixer name.
+
+    <?php
+
+    \$finder = Symfony\CS\Finder::create()
+        ->exclude('somedir')
+        ->in(__DIR__)
+    ;
+
+    return Symfony\CS\Config::create()
+        ->fixers(array('-psr0'))
+        ->finder(\$finder)
+    ;
+
+    ?>
+
+The ``symfony`` level is set by default, you can also change the default level:
+
+    <?php
+
+    return Symfony\CS\Config::create()
+        ->level(Symfony\CS\FixerInterface::PSR2_LEVEL)
+    ;
+
+    ?>
+
+In combination with these config and command line options, you can choose various usage.
+
+For example, default level is ``symfony``, but if you also don't want to use
+the ``psr0`` fixer, you can specify the ``--fixers="-psr0"`` option.
+
+But if you use the ``--fixers`` option with only exact fixers,
+only those exact fixers are enabled whether or not level is set.
+
+With the <comment>--config-file</comment> option you can specify the path to the
+<comment>.php_cs</comment> file.
+
+Caching
+-------
+
+You can enable caching by returning a custom config with caching enabled. This will
+speed up further runs.
+
+    <?php
+
+    return Symfony\CS\Config::create()
+        ->setUsingCache(true)
+    ;
+
+    ?>

+PHP Coding Standards Fixer
+==========================
+
+The PHP Coding Standards Fixer tool fixes *most* issues in your code when you
+want to follow the PHP coding standards as defined in the PSR-1 and PSR-2
+documents and many more.
+
+If you are already using a linter to identify coding standards problems in your
+code, you know that fixing them by hand is tedious, especially on large
+projects. This tool does not only detect them, but also fixes them for you.
+
+Requirements
+------------
+
+PHP needs to be a minimum version of PHP 5.3.6.
+
+Installation
+------------
+
+Locally
+~~~~~~~
+
+Download the `php-cs-fixer.phar`_ file and store it somewhere on your computer.
+
+Globally (manual)
+~~~~~~~~~~~~~~~~~
+
+You can run these commands to easily access ``php-cs-fixer`` from anywhere on
+your system:
+
+.. code-block:: bash
+
+    $ wget %download.url% -O php-cs-fixer
+
+or with curl:
+
+.. code-block:: bash
+
+    $ curl -L %download.url% -o php-cs-fixer
+
+then:
+
+.. code-block:: bash
+
+    $ sudo chmod a+x php-cs-fixer
+    $ sudo mv php-cs-fixer /usr/local/bin/php-cs-fixer
+
+Then, just run ``php-cs-fixer``.
+
+Globally (Composer)
+~~~~~~~~~~~~~~~~~~~
+
+To install PHP CS Fixer, install Composer and issue the following command:
+
+.. code-block:: bash
+
+    $ ./composer.phar global require friendsofphp/php-cs-fixer
+
+Please be aware that before v1.12 package name was different:
+
+.. code-block:: bash
+
+    $ ./composer.phar global require fabpot/php-cs-fixer
+
+Then make sure you have ``~/.composer/vendor/bin`` in your ``PATH`` and
+you're good to go:
+
+.. code-block:: bash
+
+    $ export PATH="$PATH:$HOME/.composer/vendor/bin"
+
+Globally (homebrew)
+~~~~~~~~~~~~~~~~~~~
+
+PHP-CS-Fixer is part of the homebrew-php project. Follow the installation
+instructions at https://github.com/homebrew/homebrew-php if you don't
+already have it.
+
+.. code-block:: bash
+
+    $ brew install homebrew/php/php-cs-fixer
+
+Update
+------
+
+Locally
+~~~~~~~
+
+The ``self-update`` command tries to update ``php-cs-fixer`` itself:
+
+.. code-block:: bash
+
+    $ php php-cs-fixer.phar self-update
+
+Globally (manual)
+~~~~~~~~~~~~~~~~~
+
+You can update ``php-cs-fixer`` through this command:
+
+.. code-block:: bash
+
+    $ sudo php-cs-fixer self-update
+
+Globally (Composer)
+~~~~~~~~~~~~~~~~~~~
+
+You can update ``php-cs-fixer`` through this command:
+
+.. code-block:: bash
+
+    $ ./composer.phar global update friendsofphp/php-cs-fixer
+
+Globally (homebrew)
+~~~~~~~~~~~~~~~~~~~
+
+You can update ``php-cs-fixer`` through this command:
+
+.. code-block:: bash
+
+    $ brew upgrade php-cs-fixer
+
+Usage
+-----
+
+EOF;
+
+        $footer = <<<'EOF'
+
+Helpers
+-------
+
+Dedicated plugins exist for:
+
+* `Atom`_
+* `NetBeans`_
+* `PhpStorm`_
+* `Sublime Text`_
+* `Vim`_
+
+Contribute
+----------
+
+The tool comes with quite a few built-in fixers and finders, but everyone is
+more than welcome to `contribute`_ more of them.
+
+Fixers
+~~~~~~
+
+A *fixer* is a class that tries to fix one CS issue (a ``Fixer`` class must
+implement ``FixerInterface``).
+
+Configs
+~~~~~~~
+
+A *config* knows about the CS level and the files and directories that must be
+scanned by the tool when run in the directory of your project. It is useful for
+projects that follow a well-known directory structures (like for Symfony
+projects for instance).

+  https://github.com/guzzle/guzzle/pull/1189
+
+## 6.0.2 - 2015-07-04
+
+* Fixed a memory leak in the curl handlers in which references to callbacks
+  were not being removed by `curl_reset`.
+* Cookies are now extracted properly before redirects.
+* Cookies now allow more character ranges.
+* Decoded Content-Encoding responses are now modified to correctly reflect
+  their state if the encoding was automatically removed by a handler. This
+  means that the `Content-Encoding` header may be removed an the
+  `Content-Length` modified to reflect the message size after removing the
+  encoding.
+* Added a more explicit error message when trying to use `form_params` and
+  `multipart` in the same request.
+* Several fixes for HHVM support.
+* Functions are now conditionally required using an additional level of
+  indirection to help with global Composer installations.
+
+## 6.0.1 - 2015-05-27
+
+* Fixed a bug with serializing the `query` request option where the `&`
+  separator was missing.
+* Added a better error message for when `body` is provided as an array. Please
+  use `form_params` or `multipart` instead.
+* Various doc fixes.
+
+## 6.0.0 - 2015-05-26
+
+* See the UPGRADING.md document for more information.
+* Added `multipart` and `form_params` request options.
+* Added `synchronous` request option.
+* Added the `on_headers` request option.
+* Fixed `expect` handling.
+* No longer adding default middlewares in the client ctor. These need to be
+  present on the provided handler in order to work.
+* Requests are no longer initiated when sending async requests with the
+  CurlMultiHandler. This prevents unexpected recursion from requests completing
+  while ticking the cURL loop.
+* Removed the semantics of setting `default` to `true`. This is no longer
+  required now that the cURL loop is not ticked for async requests.
+* Added request and response logging middleware.
+* No longer allowing self signed certificates when using the StreamHandler.
+* Ensuring that `sink` is valid if saving to a file.
+* Request exceptions now include a "handler context" which provides handler
+  specific contextual information.
+* Added `GuzzleHttp\RequestOptions` to allow request options to be applied
+  using constants.
+* `$maxHandles` has been removed from CurlMultiHandler.
+* `MultipartPostBody` is now part of the `guzzlehttp/psr7` package.
+
+## 5.3.0 - 2015-05-19
+
+* Mock now supports `save_to`
+* Marked `AbstractRequestEvent::getTransaction()` as public.
+* Fixed a bug in which multiple headers using different casing would overwrite
+  previous headers in the associative array.
+* Added `Utils::getDefaultHandler()`
+* Marked `GuzzleHttp\Client::getDefaultUserAgent` as deprecated.
+* URL scheme is now always lowercased.
+
+## 6.0.0-beta.1
+
+* Requires PHP >= 5.5
+* Updated to use PSR-7
+  * Requires immutable messages, which basically means an event based system
+    owned by a request instance is no longer possible.
+  * Utilizing the [Guzzle PSR-7 package](https://github.com/guzzle/psr7).
+  * Removed the dependency on `guzzlehttp/streams`. These stream abstractions
+    are available in the `guzzlehttp/psr7` package under the `GuzzleHttp\Psr7`
+    namespace.
+* Added middleware and handler system
+  * Replaced the Guzzle event and subscriber system with a middleware system.
+  * No longer depends on RingPHP, but rather places the HTTP handlers directly
+    in Guzzle, operating on PSR-7 messages.
+  * Retry logic is now encapsulated in `GuzzleHttp\Middleware::retry`, which
+    means the `guzzlehttp/retry-subscriber` is now obsolete.
+  * Mocking responses is now handled using `GuzzleHttp\Handler\MockHandler`.
+* Asynchronous responses
+  * No longer supports the `future` request option to send an async request.
+    Instead, use one of the `*Async` methods of a client (e.g., `requestAsync`,
+    `getAsync`, etc.).
+  * Utilizing `GuzzleHttp\Promise` instead of React's promise library to avoid
+    recursion required by chaining and forwarding react promises. See
+    https://github.com/guzzle/promises
+  * Added `requestAsync` and `sendAsync` to send request asynchronously.
+  * Added magic methods for `getAsync()`, `postAsync()`, etc. to send requests
+    asynchronously.
+* Request options
+  * POST and form updates
+    * Added the `form_fields` and `form_files` request options.
+    * Removed the `GuzzleHttp\Post` namespace.
+    * The `body` request option no longer accepts an array for POST requests.
+  * The `exceptions` request option has been deprecated in favor of the
+    `http_errors` request options.
+  * The `save_to` request option has been deprecated in favor of `sink` request
+    option.
+* Clients no longer accept an array of URI template string and variables for
+  URI variables. You will need to expand URI templates before passing them
+  into a client constructor or request method.
+* Client methods `get()`, `post()`, `put()`, `patch()`, `options()`, etc. are
+  now magic methods that will send synchronous requests.
+* Replaced `Utils.php` with plain functions in `functions.php`.
+* Removed `GuzzleHttp\Collection`.
+* Removed `GuzzleHttp\BatchResults`. Batched pool results are now returned as
+  an array.
+* Removed `GuzzleHttp\Query`. Query string handling is now handled using an
+  associative array passed into the `query` request option. The query string
+  is serialized using PHP's `http_build_query`. If you need more control, you
+  can pass the query string in as a string.
+* `GuzzleHttp\QueryParser` has been replaced with the
+  `GuzzleHttp\Psr7\parse_query`.
+
+## 5.2.0 - 2015-01-27
+
+* Added `AppliesHeadersInterface` to make applying headers to a request based
+  on the body more generic and not specific to `PostBodyInterface`.
+* Reduced the number of stack frames needed to send requests.
+* Nested futures are now resolved in the client rather than the RequestFsm
+* Finishing state transitions is now handled in the RequestFsm rather than the
+  RingBridge.
+* Added a guard in the Pool class to not use recursion for request retries.
+
+## 5.1.0 - 2014-12-19
+
+* Pool class no longer uses recursion when a request is intercepted.
+* The size of a Pool can now be dynamically adjusted using a callback.
+  See https://github.com/guzzle/guzzle/pull/943.
+* Setting a request option to `null` when creating a request with a client will
+  ensure that the option is not set. This allows you to overwrite default
+  request options on a per-request basis.
+  See https://github.com/guzzle/guzzle/pull/937.
+* Added the ability to limit which protocols are allowed for redirects by
+  specifying a `protocols` array in the `allow_redirects` request option.
+* Nested futures due to retries are now resolved when waiting for synchronous
+  responses. See https://github.com/guzzle/guzzle/pull/947.
+* `"0"` is now an allowed URI path. See
+  https://github.com/guzzle/guzzle/pull/935.
+* `Query` no longer typehints on the `$query` argument in the constructor,
+  allowing for strings and arrays.
+* Exceptions thrown in the `end` event are now correctly wrapped with Guzzle
+  specific exceptions if necessary.
+
+## 5.0.3 - 2014-11-03
+
+This change updates query strings so that they are treated as un-encoded values
+by default where the value represents an un-encoded value to send over the
+wire. A Query object then encodes the value before sending over the wire. This
+means that even value query string values (e.g., ":") are url encoded. This
+makes the Query class match PHP's http_build_query function. However, if you
+want to send requests over the wire using valid query string characters that do
+not need to be encoded, then you can provide a string to Url::setQuery() and
+pass true as the second argument to specify that the query string is a raw
+string that should not be parsed or encoded (unless a call to getQuery() is
+subsequently made, forcing the query-string to be converted into a Query
+object).
+
+## 5.0.2 - 2014-10-30
+
+* Added a trailing `\r\n` to multipart/form-data payloads. See
+  https://github.com/guzzle/guzzle/pull/871
+* Added a `GuzzleHttp\Pool::send()` convenience method to match the docs.
+* Status codes are now returned as integers. See
+  https://github.com/guzzle/guzzle/issues/881
+* No longer overwriting an existing `application/x-www-form-urlencoded` header
+  when sending POST requests, allowing for customized headers. See
+  https://github.com/guzzle/guzzle/issues/877
+* Improved path URL serialization.
+
+  * No longer double percent-encoding characters in the path or query string if
+    they are already encoded.
+  * Now properly encoding the supplied path to a URL object, instead of only
+    encoding ' ' and '?'.
+  * Note: This has been changed in 5.0.3 to now encode query string values by
+    default unless the `rawString` argument is provided when setting the query
+    string on a URL: Now allowing many more characters to be present in the
+    query string without being percent encoded. See http://tools.ietf.org/html/rfc3986#appendix-A
+
+## 5.0.1 - 2014-10-16
+
+Bugfix release.
+
+* Fixed an issue where connection errors still returned response object in
+  error and end events event though the response is unusable. This has been
+  corrected so that a response is not returned in the `getResponse` method of
+  these events if the response did not complete. https://github.com/guzzle/guzzle/issues/867
+* Fixed an issue where transfer statistics were not being populated in the
+  RingBridge. https://github.com/guzzle/guzzle/issues/866
+
+## 5.0.0 - 2014-10-12
+
+Adding support for non-blocking responses and some minor API cleanup.
+
+### New Features
+
+* Added support for non-blocking responses based on `guzzlehttp/guzzle-ring`.
+* Added a public API for creating a default HTTP adapter.
+* Updated the redirect plugin to be non-blocking so that redirects are sent
+  concurrently. Other plugins like this can now be updated to be non-blocking.
+* Added a "progress" event so that you can get upload and download progress
+  events.
+* Added `GuzzleHttp\Pool` which implements FutureInterface and transfers
+  requests concurrently using a capped pool size as efficiently as possible.
+* Added `hasListeners()` to EmitterInterface.
+* Removed `GuzzleHttp\ClientInterface::sendAll` and marked
+  `GuzzleHttp\Client::sendAll` as deprecated (it's still there, just not the
+  recommended way).
+
+### Breaking changes
+
+The breaking changes in this release are relatively minor. The biggest thing to
+look out for is that request and response objects no longer implement fluent
+interfaces.
+
+* Removed the fluent interfaces (i.e., `return $this`) from requests,
+  responses, `GuzzleHttp\Collection`, `GuzzleHttp\Url`,
+  `GuzzleHttp\Query`, `GuzzleHttp\Post\PostBody`, and
+  `GuzzleHttp\Cookie\SetCookie`. This blog post provides a good outline of
+  why I did this: http://ocramius.github.io/blog/fluent-interfaces-are-evil/.
+  This also makes the Guzzle message interfaces compatible with the current
+  PSR-7 message proposal.
+* Removed "functions.php", so that Guzzle is truly PSR-4 compliant. Except
+  for the HTTP request functions from function.php, these functions are now
+  implemented in `GuzzleHttp\Utils` using camelCase. `GuzzleHttp\json_decode`
+  moved to `GuzzleHttp\Utils::jsonDecode`. `GuzzleHttp\get_path` moved to
+  `GuzzleHttp\Utils::getPath`. `GuzzleHttp\set_path` moved to
+  `GuzzleHttp\Utils::setPath`. `GuzzleHttp\batch` should now be
+  `GuzzleHttp\Pool::batch`, which returns an `objectStorage`. Using functions.php
+  caused problems for many users: they aren't PSR-4 compliant, require an
+  explicit include, and needed an if-guard to ensure that the functions are not
+  declared multiple times.
+* Rewrote adapter layer.
+    * Removing all classes from `GuzzleHttp\Adapter`, these are now
+      implemented as callables that are stored in `GuzzleHttp\Ring\Client`.
+    * Removed the concept of "parallel adapters". Sending requests serially or
+      concurrently is now handled using a single adapter.
+    * Moved `GuzzleHttp\Adapter\Transaction` to `GuzzleHttp\Transaction`. The
+      Transaction object now exposes the request, response, and client as public
+      properties. The getters and setters have been removed.
+* Removed the "headers" event. This event was only useful for changing the
+  body a response once the headers of the response were known. You can implement
+  a similar behavior in a number of ways. One example might be to use a
+  FnStream that has access to the transaction being sent. For example, when the
+  first byte is written, you could check if the response headers match your
+  expectations, and if so, change the actual stream body that is being
+  written to.
+* Removed the `asArray` parameter from
+  `GuzzleHttp\Message\MessageInterface::getHeader`. If you want to get a header
+  value as an array, then use the newly added `getHeaderAsArray()` method of
+  `MessageInterface`. This change makes the Guzzle interfaces compatible with
+  the PSR-7 interfaces.
+* `GuzzleHttp\Message\MessageFactory` no longer allows subclasses to add
+  custom request options using double-dispatch (this was an implementation
+  detail). Instead, you should now provide an associative array to the
+  constructor which is a mapping of the request option name mapping to a
+  function that applies the option value to a request.
+* Removed the concept of "throwImmediately" from exceptions and error events.
+  This control mechanism was used to stop a transfer of concurrent requests
+  from completing. This can now be handled by throwing the exception or by
+  cancelling a pool of requests or each outstanding future request individually.
+* Updated to "GuzzleHttp\Streams" 3.0.
+    * `GuzzleHttp\Stream\StreamInterface::getContents()` no longer accepts a
+      `maxLen` parameter. This update makes the Guzzle streams project
+      compatible with the current PSR-7 proposal.
+    * `GuzzleHttp\Stream\Stream::__construct`,
+      `GuzzleHttp\Stream\Stream::factory`, and
+      `GuzzleHttp\Stream\Utils::create` no longer accept a size in the second
+      argument. They now accept an associative array of options, including the
+      "size" key and "metadata" key which can be used to provide custom metadata.
+
+## 4.2.2 - 2014-09-08
+
+* Fixed a memory leak in the CurlAdapter when reusing cURL handles.
+* No longer using `request_fulluri` in stream adapter proxies.
+* Relative redirects are now based on the last response, not the first response.
+
+## 4.2.1 - 2014-08-19
+
+* Ensuring that the StreamAdapter does not always add a Content-Type header
+* Adding automated github releases with a phar and zip
+
+## 4.2.0 - 2014-08-17
+
+* Now merging in default options using a case-insensitive comparison.
+  Closes https://github.com/guzzle/guzzle/issues/767
+* Added the ability to automatically decode `Content-Encoding` response bodies
+  using the `decode_content` request option. This is set to `true` by default
+  to decode the response body if it comes over the wire with a
+  `Content-Encoding`. Set this value to `false` to disable decoding the
+  response content, and pass a string to provide a request `Accept-Encoding`
+  header and turn on automatic response decoding. This feature now allows you
+  to pass an `Accept-Encoding` header in the headers of a request but still
+  disable automatic response decoding.
+  Closes https://github.com/guzzle/guzzle/issues/764
+* Added the ability to throw an exception immediately when transferring
+  requests in parallel. Closes https://github.com/guzzle/guzzle/issues/760
+* Updating guzzlehttp/streams dependency to ~2.1
+* No longer utilizing the now deprecated namespaced methods from the stream
+  package.
+
+## 4.1.8 - 2014-08-14
+
+* Fixed an issue in the CurlFactory that caused setting the `stream=false`
+  request option to throw an exception.
+  See: https://github.com/guzzle/guzzle/issues/769
+* TransactionIterator now calls rewind on the inner iterator.
+  See: https://github.com/guzzle/guzzle/pull/765
+* You can now set the `Content-Type` header to `multipart/form-data`
+  when creating POST requests to force multipart bodies.
+  See https://github.com/guzzle/guzzle/issues/768
+
+## 4.1.7 - 2014-08-07
+
+* Fixed an error in the HistoryPlugin that caused the same request and response
+  to be logged multiple times when an HTTP protocol error occurs.
+* Ensuring that cURL does not add a default Content-Type when no Content-Type
+  has been supplied by the user. This prevents the adapter layer from modifying
+  the request that is sent over the wire after any listeners may have already
+  put the request in a desired state (e.g., signed the request).
+* Throwing an exception when you attempt to send requests that have the
+  "stream" set to true in parallel using the MultiAdapter.
+* Only calling curl_multi_select when there are active cURL handles. This was
+  previously changed and caused performance problems on some systems due to PHP
+  always selecting until the maximum select timeout.
+* Fixed a bug where multipart/form-data POST fields were not correctly
+  aggregated (e.g., values with "&").
+
+## 4.1.6 - 2014-08-03
+
+* Added helper methods to make it easier to represent messages as strings,
+  including getting the start line and getting headers as a string.
+
+## 4.1.5 - 2014-08-02
+
+* Automatically retrying cURL "Connection died, retrying a fresh connect"
+  errors when possible.
+* cURL implementation cleanup
+* Allowing multiple event subscriber listeners to be registered per event by
+  passing an array of arrays of listener configuration.
+
+## 4.1.4 - 2014-07-22
+
+* Fixed a bug that caused multi-part POST requests with more than one field to
+  serialize incorrectly.
+* Paths can now be set to "0"
+* `ResponseInterface::xml` now accepts a `libxml_options` option and added a
+  missing default argument that was required when parsing XML response bodies.
+* A `save_to` stream is now created lazily, which means that files are not
+  created on disk unless a request succeeds.
+
+## 4.1.3 - 2014-07-15
+
+* Various fixes to multipart/form-data POST uploads
+* Wrapping function.php in an if-statement to ensure Guzzle can be used
+  globally and in a Composer install
+* Fixed an issue with generating and merging in events to an event array
+* POST headers are only applied before sending a request to allow you to change
+  the query aggregator used before uploading
+* Added much more robust query string parsing
+* Fixed various parsing and normalization issues with URLs
+* Fixing an issue where multi-valued headers were not being utilized correctly
+  in the StreamAdapter
+
+## 4.1.2 - 2014-06-18
+
+* Added support for sending payloads with GET requests
+
+## 4.1.1 - 2014-06-08
+
+* Fixed an issue related to using custom message factory options in subclasses
+* Fixed an issue with nested form fields in a multi-part POST
+* Fixed an issue with using the `json` request option for POST requests
+* Added `ToArrayInterface` to `GuzzleHttp\Cookie\CookieJar`
+
+## 4.1.0 - 2014-05-27
+
+* Added a `json` request option to easily serialize JSON payloads.
+* Added a `GuzzleHttp\json_decode()` wrapper to safely parse JSON.
+* Added `setPort()` and `getPort()` to `GuzzleHttp\Message\RequestInterface`.
+* Added the ability to provide an emitter to a client in the client constructor.
+* Added the ability to persist a cookie session using $_SESSION.
+* Added a trait that can be used to add event listeners to an iterator.
+* Removed request method constants from RequestInterface.
+* Fixed warning when invalid request start-lines are received.
+* Updated MessageFactory to work with custom request option methods.
+* Updated cacert bundle to latest build.
+
+4.0.2 (2014-04-16)
+------------------
+
+* Proxy requests using the StreamAdapter now properly use request_fulluri (#632)
+* Added the ability to set scalars as POST fields (#628)
+
+## 4.0.1 - 2014-04-04
+
+* The HTTP status code of a response is now set as the exception code of
+  RequestException objects.
+* 303 redirects will now correctly switch from POST to GET requests.
+* The default parallel adapter of a client now correctly uses the MultiAdapter.
+* HasDataTrait now initializes the internal data array as an empty array so
+  that the toArray() method always returns an array.
+
+## 4.0.0 - 2014-03-29
+
+* For more information on the 4.0 transition, see:
+  http://mtdowling.com/blog/2014/03/15/guzzle-4-rc/
+* For information on changes and upgrading, see:

+* Added `GuzzleHttp\batch()` as a convenience function for sending requests in
+  parallel without needing to write asynchronous code.
+* Restructured how events are added to `GuzzleHttp\ClientInterface::sendAll()`.
+  You can now pass a callable or an array of associative arrays where each
+  associative array contains the "fn", "priority", and "once" keys.
+
+## 4.0.0.rc-2 - 2014-03-25
+
+* Removed `getConfig()` and `setConfig()` from clients to avoid confusion
+  around whether things like base_url, message_factory, etc. should be able to
+  be retrieved or modified.
+* Added `getDefaultOption()` and `setDefaultOption()` to ClientInterface
+* functions.php functions were renamed using snake_case to match PHP idioms
+* Added support for `HTTP_PROXY`, `HTTPS_PROXY`, and
+  `GUZZLE_CURL_SELECT_TIMEOUT` environment variables
+* Added the ability to specify custom `sendAll()` event priorities
+* Added the ability to specify custom stream context options to the stream
+  adapter.
+* Added a functions.php function for `get_path()` and `set_path()`
+* CurlAdapter and MultiAdapter now use a callable to generate curl resources
+* MockAdapter now properly reads a body and emits a `headers` event
+* Updated Url class to check if a scheme and host are set before adding ":"
+  and "//". This allows empty Url (e.g., "") to be serialized as "".
+* Parsing invalid XML no longer emits warnings
+* Curl classes now properly throw AdapterExceptions
+* Various performance optimizations
+* Streams are created with the faster `Stream\create()` function
+* Marked deprecation_proxy() as internal

+* Bug: The body of a request can now be set to `"0"`
+* Sending PHP stream requests no longer forces `HTTP/1.0`
+* Adding more information to ExceptionCollection exceptions so that users have more context, including a stack trace of
+  each sub-exception
+* Updated the `$ref` attribute in service descriptions to merge over any existing parameters of a schema (rather than
+  clobbering everything).
+* Merging URLs will now use the query string object from the relative URL (thus allowing custom query aggregators)
+* Query strings are now parsed in a way that they do no convert empty keys with no value to have a dangling `=`.
+  For example `foo&bar=baz` is now correctly parsed and recognized as `foo&bar=baz` rather than `foo=&bar=baz`.
+* Now properly escaping the regular expression delimiter when matching Cookie domains.
+* Network access is now disabled when loading XML documents
+

+* OauthPlugin now supports adding authentication to headers or query string (#425)
+
+## 3.7.3 - 2013-09-08
+
+* Added the ability to get the exception associated with a request/command when using `MultiTransferException` and
+  `CommandTransferException`.
+* Setting `additionalParameters` of a response to false is now honored when parsing responses with a service description
+* Schemas are only injected into response models when explicitly configured.

+
+## 3.7.0 - 2013-06-10
+
+* See UPGRADING.md for more information on how to upgrade.
+* Requests now support the ability to specify an array of $options when creating a request to more easily modify a
+  request. You can pass a 'request.options' configuration setting to a client to apply default request options to
+  every request created by a client (e.g. default query string variables, headers, curl options, etc.).
+* Added a static facade class that allows you to use Guzzle with static methods and mount the class to `\Guzzle`.
+  See `Guzzle\Http\StaticClient::mount`.
+* Added `command.request_options` to `Guzzle\Service\Command\AbstractCommand` to pass request options to requests
+      created by a command (e.g. custom headers, query string variables, timeout settings, etc.).
+* Stream size in `Guzzle\Stream\PhpStreamRequestFactory` will now be set if Content-Length is returned in the
+  headers of a response
+* Added `Guzzle\Common\Collection::setPath($path, $value)` to set a value into an array using a nested key
+  (e.g. `$collection->setPath('foo/baz/bar', 'test'); echo $collection['foo']['bar']['bar'];`)
+* ServiceBuilders now support storing and retrieving arbitrary data
+* CachePlugin can now purge all resources for a given URI
+* CachePlugin can automatically purge matching cached items when a non-idempotent request is sent to a resource
+* CachePlugin now uses the Vary header to determine if a resource is a cache hit
+* `Guzzle\Http\Message\Response` now implements `\Serializable`
+* Added `Guzzle\Cache\CacheAdapterFactory::fromCache()` to more easily create cache adapters
+* `Guzzle\Service\ClientInterface::execute()` now accepts an array, single command, or Traversable
+* Fixed a bug in `Guzzle\Http\Message\Header\Link::addLink()`
+* Better handling of calculating the size of a stream in `Guzzle\Stream\Stream` using fstat() and caching the size
+* `Guzzle\Common\Exception\ExceptionCollection` now creates a more readable exception message
+* Fixing BC break: Added back the MonologLogAdapter implementation rather than extending from PsrLog so that older
+  Symfony users can still use the old version of Monolog.
+* Fixing BC break: Added the implementation back in for `Guzzle\Http\Message\AbstractMessage::getTokenizedHeader()`.
+  Now triggering an E_USER_DEPRECATED warning when used. Use `$message->getHeader()->parseParams()`.
+* Several performance improvements to `Guzzle\Common\Collection`
+* Added an `$options` argument to the end of the following methods of `Guzzle\Http\ClientInterface`:
+  createRequest, head, delete, put, patch, post, options, prepareRequest
+* Added an `$options` argument to the end of `Guzzle\Http\Message\Request\RequestFactoryInterface::createRequest()`
+* Added an `applyOptions()` method to `Guzzle\Http\Message\Request\RequestFactoryInterface`
+* Changed `Guzzle\Http\ClientInterface::get($uri = null, $headers = null, $body = null)` to
+  `Guzzle\Http\ClientInterface::get($uri = null, $headers = null, $options = array())`. You can still pass in a
+  resource, string, or EntityBody into the $options parameter to specify the download location of the response.
+* Changed `Guzzle\Common\Collection::__construct($data)` to no longer accepts a null value for `$data` but a
+  default `array()`
+* Added `Guzzle\Stream\StreamInterface::isRepeatable`
+* Removed `Guzzle\Http\ClientInterface::setDefaultHeaders(). Use
+  $client->getConfig()->setPath('request.options/headers/{header_name}', 'value')`. or
+  $client->getConfig()->setPath('request.options/headers', array('header_name' => 'value'))`.
+* Removed `Guzzle\Http\ClientInterface::getDefaultHeaders(). Use $client->getConfig()->getPath('request.options/headers')`.
+* Removed `Guzzle\Http\ClientInterface::expandTemplate()`
+* Removed `Guzzle\Http\ClientInterface::setRequestFactory()`
+* Removed `Guzzle\Http\ClientInterface::getCurlMulti()`
+* Removed `Guzzle\Http\Message\RequestInterface::canCache`
+* Removed `Guzzle\Http\Message\RequestInterface::setIsRedirect`
+* Removed `Guzzle\Http\Message\RequestInterface::isRedirect`
+* Made `Guzzle\Http\Client::expandTemplate` and `getUriTemplate` protected methods.
+* You can now enable E_USER_DEPRECATED warnings to see if you are using a deprecated method by setting
+  `Guzzle\Common\Version::$emitWarnings` to true.
+* Marked `Guzzle\Http\Message\Request::isResponseBodyRepeatable()` as deprecated. Use
+      `$request->getResponseBody()->isRepeatable()` instead.
+* Marked `Guzzle\Http\Message\Request::canCache()` as deprecated. Use
+  `Guzzle\Plugin\Cache\DefaultCanCacheStrategy->canCacheRequest()` instead.
+* Marked `Guzzle\Http\Message\Request::canCache()` as deprecated. Use
+  `Guzzle\Plugin\Cache\DefaultCanCacheStrategy->canCacheRequest()` instead.

+  CacheStorageInterface. These two objects and interface will be removed in a future version.
+* Always setting X-cache headers on cached responses
+* Default cache TTLs are now handled by the CacheStorageInterface of a CachePlugin
+* `CacheStorageInterface::cache($key, Response $response, $ttl = null)` has changed to `cache(RequestInterface

+## 3.6.0 - 2013-05-29
+
+* ServiceDescription now implements ToArrayInterface
+* Added command.hidden_params to blacklist certain headers from being treated as additionalParameters
+* Guzzle can now correctly parse incomplete URLs
+* Mixed casing of headers are now forced to be a single consistent casing across all values for that header.
+* Messages internally use a HeaderCollection object to delegate handling case-insensitive header resolution
+* Removed the whole changedHeader() function system of messages because all header changes now go through addHeader().
+* Specific header implementations can be created for complex headers. When a message creates a header, it uses a
+  HeaderFactory which can map specific headers to specific header classes. There is now a Link header and
+  CacheControl header implementation.
+* Removed from interface: Guzzle\Http\ClientInterface::setUriTemplate
+* Removed from interface: Guzzle\Http\ClientInterface::setCurlMulti()
+* Removed Guzzle\Http\Message\Request::receivedRequestHeader() and implemented this functionality in
+  Guzzle\Http\Curl\RequestMediator

+* Removed the optional $tryChunkedTransfer option from Guzzle\Http\Message\EntityEnclosingRequestInterface
+* Removed the $asObjects argument from Guzzle\Http\Message\MessageInterface::getHeaders()
+* Removed Guzzle\Parser\ParserRegister::get(). Use getParser()
+* Removed Guzzle\Parser\ParserRegister::set(). Use registerParser().

+* Removed cURL blacklist support. This is no longer necessary now that Expect, Accept, etc. are managed by Guzzle
+  directly via interfaces
+* Removed the injecting of a request object onto a response object. The methods to get and set a request still exist
+  but are a no-op until removed.
+* Most classes that used to require a `Guzzle\Service\Command\CommandInterface` typehint now request a
+  `Guzzle\Service\Command\ArrayCommandInterface`.
+* Added `Guzzle\Http\Message\RequestInterface::startResponse()` to the RequestInterface to handle injecting a response
+  on a request while the request is still being transferred
+* The ability to case-insensitively search for header values
+* Guzzle\Http\Message\Header::hasExactHeader
+* Guzzle\Http\Message\Header::raw. Use getAll()
+* Deprecated cache control specific methods on Guzzle\Http\Message\AbstractMessage. Use the CacheControl header object
+  instead.
+* `Guzzle\Service\Command\CommandInterface` now extends from ToArrayInterface and ArrayAccess
+* Added the ability to cast Model objects to a string to view debug information.
+

+* Bug: Better cleanup of one-time events across the board (when an event is meant to fire once, it will now remove
+  itself from the EventDispatcher)
+* Bug: `Guzzle\Log\MessageFormatter` now properly writes "total_time" and "connect_time" values
+* Bug: Cloning an EntityEnclosingRequest now clones the EntityBody too
+* Bug: Fixed an undefined index error when parsing nested JSON responses with a sentAs parameter that reference a
+  non-existent key
+* Bug: All __call() method arguments are now required (helps with mocking frameworks)
+* Deprecating Response::getRequest() and now using a shallow clone of a request object to remove a circular reference
+  to help with refcount based garbage collection of resources created by sending a request
+* Deprecating ZF1 cache and log adapters. These will be removed in the next major version.
+* Deprecating `Response::getPreviousResponse()` (method signature still exists, but it's deprecated). Use the
+  HistoryPlugin for a history.
+* Added a `responseBody` alias for the `response_body` location
+* Refactored internals to no longer rely on Response::getRequest()
+* HistoryPlugin can now be cast to a string
+* HistoryPlugin now logs transactions rather than requests and responses to more accurately keep track of the requests
+  and responses that are sent over the wire

+* Configuration loading now allows remote files
+
+## 3.4.1 - 2013-04-16

+* Large refactoring to how CurlMulti handles work. There is now a proxy that sits in front of a pool of CurlMulti
+  handles. This greatly simplifies the implementation, fixes a couple bugs, and provides a small performance boost.
+* Exceptions are now properly grouped when sending requests in parallel
+* Redirects are now properly aggregated when a multi transaction fails
+* Redirects now set the response on the original object even in the event of a failure

+* Bug fix: Now correctly aggregating successful requests and failed requests in CurlMulti when a redirect occurs.
+* The new default CURLOPT_TIMEOUT setting has been increased to 150 seconds so that Guzzle works on poor connections.
+* Added a feature to EntityEnclosingRequest::setBody() that will automatically set the Content-Type of the request if
+  the Content-Type can be determined based on the entity body or the path of the request.
+* Added the ability to overwrite configuration settings in a client when grabbing a throwaway client from a builder.
+* Added support for a PSR-3 LogAdapter.
+* Added a `command.after_prepare` event
+* Added `oauth_callback` parameter to the OauthPlugin
+* Added the ability to create a custom stream class when using a stream factory
+* Added a CachingEntityBody decorator
+* Added support for `additionalParameters` in service descriptions to define how custom parameters are serialized.
+* The bundled SSL certificate is now provided in the phar file and extracted when running Guzzle from a phar.
+* You can now send any EntityEnclosingRequest with POST fields or POST files and cURL will handle creating bodies
+* POST requests using a custom entity body are now treated exactly like PUT requests but with a custom cURL method. This
+  means that the redirect behavior of POST requests with custom bodies will not be the same as POST requests that use
+  POST fields or files (the latter is only used when emulating a form POST in the browser).
+* Lots of cleanup to CurlHandle::factory and RequestFactory::createRequest
+

+* BC: Setting a service description on a client will no longer modify the client's command factories.
+* BC: Emitting IO events from a RequestMediator is now a parameter that must be set in a request's curl options using
+  the 'emit_io' key. This was previously set under a request's parameters using 'curl.emit_io'

+  lowercase
+* Operation parameter objects are now lazy loaded internally
+* Added ErrorResponsePlugin that can throw errors for responses defined in service description operations' errorResponses
+* Added support for instantiating responseType=class responseClass classes. Classes must implement
+  `Guzzle\Service\Command\ResponseClassInterface`

+* CachePlugin
+    * Added support for stale-if-error so that the CachePlugin can now serve stale content from the cache on error
+    * Debug headers can now added to cached response in the CachePlugin
+
+## 3.2.0 - 2013-02-14
+
+* CurlMulti is no longer reused globally. A new multi object is created per-client. This helps to isolate clients.

+Guzzle, PHP HTTP client
+=======================
+
+[![Latest Version](https://img.shields.io/github/release/guzzle/guzzle.svg?style=flat-square)](https://github.com/guzzle/guzzle/releases)
+[![Build Status](https://img.shields.io/travis/guzzle/guzzle.svg?style=flat-square)](https://travis-ci.org/guzzle/guzzle)
+[![Total Downloads](https://img.shields.io/packagist/dt/guzzlehttp/guzzle.svg?style=flat-square)](https://packagist.org/packages/guzzlehttp/guzzle)
+
+Guzzle is a PHP HTTP client that makes it easy to send HTTP requests and
+trivial to integrate with web services.
+
+- Simple interface for building query strings, POST requests, streaming large
+  uploads, streaming large downloads, using HTTP cookies, uploading JSON data,
+  etc...
+- Can send both synchronous and asynchronous requests using the same interface.
+- Uses PSR-7 interfaces for requests, responses, and streams. This allows you
+  to utilize other PSR-7 compatible libraries with Guzzle.
+- Abstracts away the underlying HTTP transport, allowing you to write
+  environment and transport agnostic code; i.e., no hard dependency on cURL,
+  PHP streams, sockets, or non-blocking event loops.
+- Middleware system allows you to augment and compose client behavior.
+
+```php
+$client = new \GuzzleHttp\Client();
+$res = $client->request('GET', 'https://api.github.com/repos/guzzle/guzzle');
+echo $res->getStatusCode();
+// 200
+echo $res->getHeaderLine('content-type');
+// 'application/json; charset=utf8'
+echo $res->getBody();
+// '{"id": 1420053, "name": "guzzle", ...}'
+
+// Send an asynchronous request.
+$request = new \GuzzleHttp\Psr7\Request('GET', 'http://httpbin.org');
+$promise = $client->sendAsync($request)->then(function ($response) {
+    echo 'I completed! ' . $response->getBody();
+});
+$promise->wait();
+```

+- [Gitter](https://gitter.im/guzzle/guzzle)
+
+
+## Installing Guzzle
+
+The recommended way to install Guzzle is through
+[Composer](http://getcomposer.org).
+
+```bash
+# Install Composer
+curl -sS https://getcomposer.org/installer | php
+```
+
+Next, run the Composer command to install the latest stable version of Guzzle:
+
+```bash
+php composer.phar require guzzlehttp/guzzle
+```
+
+After installing, you need to require Composer's autoloader:
+
+```php
+require 'vendor/autoload.php';
+```
+
+You can then later update Guzzle using composer:
+
+ ```bash
+composer.phar update
+ ```
+

+Guzzle Upgrade Guide
+====================
+
+5.0 to 6.0
+----------
+
+Guzzle now uses [PSR-7](http://www.php-fig.org/psr/psr-7/) for HTTP messages.
+Due to the fact that these messages are immutable, this prompted a refactoring
+of Guzzle to use a middleware based system rather than an event system. Any
+HTTP message interaction (e.g., `GuzzleHttp\Message\Request`) need to be
+updated to work with the new immutable PSR-7 request and response objects. Any
+event listeners or subscribers need to be updated to become middleware
+functions that wrap handlers (or are injected into a
+`GuzzleHttp\HandlerStack`).
+
+- Removed `GuzzleHttp\BatchResults`
+- Removed `GuzzleHttp\Collection`
+- Removed `GuzzleHttp\HasDataTrait`
+- Removed `GuzzleHttp\ToArrayInterface`
+- The `guzzlehttp/streams` dependency has been removed. Stream functionality
+  is now present in the `GuzzleHttp\Psr7` namespace provided by the
+  `guzzlehttp/psr7` package.
+- Guzzle no longer uses ReactPHP promises and now uses the
+  `guzzlehttp/promises` library. We use a custom promise library for three
+  significant reasons:
+  1. React promises (at the time of writing this) are recursive. Promise
+     chaining and promise resolution will eventually blow the stack. Guzzle
+     promises are not recursive as they use a sort of trampolining technique.
+     Note: there has been movement in the React project to modify promises to
+     no longer utilize recursion.
+  2. Guzzle needs to have the ability to synchronously block on a promise to
+     wait for a result. Guzzle promises allows this functionality (and does
+     not require the use of recursion).
+  3. Because we need to be able to wait on a result, doing so using React
+     promises requires wrapping react promises with RingPHP futures. This
+     overhead is no longer needed, reducing stack sizes, reducing complexity,
+     and improving performance.
+- `GuzzleHttp\Mimetypes` has been moved to a function in
+  `GuzzleHttp\Psr7\mimetype_from_extension` and
+  `GuzzleHttp\Psr7\mimetype_from_filename`.
+- `GuzzleHttp\Query` and `GuzzleHttp\QueryParser` have been removed. Query
+  strings must now be passed into request objects as strings, or provided to
+  the `query` request option when creating requests with clients. The `query`
+  option uses PHP's `http_build_query` to convert an array to a string. If you
+  need a different serialization technique, you will need to pass the query
+  string in as a string. There are a couple helper functions that will make
+  working with query strings easier: `GuzzleHttp\Psr7\parse_query` and
+  `GuzzleHttp\Psr7\build_query`.
+- Guzzle no longer has a dependency on RingPHP. Due to the use of a middleware
+  system based on PSR-7, using RingPHP and it's middleware system as well adds
+  more complexity than the benefits it provides. All HTTP handlers that were
+  present in RingPHP have been modified to work directly with PSR-7 messages
+  and placed in the `GuzzleHttp\Handler` namespace. This significantly reduces
+  complexity in Guzzle, removes a dependency, and improves performance. RingPHP
+  will be maintained for Guzzle 5 support, but will no longer be a part of
+  Guzzle 6.
+- As Guzzle now uses a middleware based systems the event system and RingPHP
+  integration has been removed. Note: while the event system has been removed,
+  it is possible to add your own type of event system that is powered by the
+  middleware system.
+  - Removed the `Event` namespace.
+  - Removed the `Subscriber` namespace.
+  - Removed `Transaction` class
+  - Removed `RequestFsm`
+  - Removed `RingBridge`
+  - `GuzzleHttp\Subscriber\Cookie` is now provided by
+    `GuzzleHttp\Middleware::cookies`
+  - `GuzzleHttp\Subscriber\HttpError` is now provided by
+    `GuzzleHttp\Middleware::httpError`
+  - `GuzzleHttp\Subscriber\History` is now provided by
+    `GuzzleHttp\Middleware::history`
+  - `GuzzleHttp\Subscriber\Mock` is now provided by
+    `GuzzleHttp\Handler\MockHandler`
+  - `GuzzleHttp\Subscriber\Prepare` is now provided by
+    `GuzzleHttp\PrepareBodyMiddleware`
+  - `GuzzleHttp\Subscriber\Redirect` is now provided by
+    `GuzzleHttp\RedirectMiddleware`
+- Guzzle now uses `Psr\Http\Message\UriInterface` (implements in
+  `GuzzleHttp\Psr7\Uri`) for URI support. `GuzzleHttp\Url` is now gone.
+- Static functions in `GuzzleHttp\Utils` have been moved to namespaced
+  functions under the `GuzzleHttp` namespace. This requires either a Composer
+  based autoloader or you to include functions.php.
+- `GuzzleHttp\ClientInterface::getDefaultOption` has been renamed to
+  `GuzzleHttp\ClientInterface::getConfig`.
+- `GuzzleHttp\ClientInterface::setDefaultOption` has been removed.
+- The `json` and `xml` methods of response objects has been removed. With the
+  migration to strictly adhering to PSR-7 as the interface for Guzzle messages,
+  adding methods to message interfaces would actually require Guzzle messages
+  to extend from PSR-7 messages rather then work with them directly.
+
+## Migrating to middleware
+
+The change to PSR-7 unfortunately required significant refactoring to Guzzle
+due to the fact that PSR-7 messages are immutable. Guzzle 5 relied on an event
+system from plugins. The event system relied on mutability of HTTP messages and
+side effects in order to work. With immutable messages, you have to change your
+workflow to become more about either returning a value (e.g., functional
+middlewares) or setting a value on an object. Guzzle v6 has chosen the
+functional middleware approach.
+
+Instead of using the event system to listen for things like the `before` event,
+you now create a stack based middleware function that intercepts a request on
+the way in and the promise of the response on the way out. This is a much
+simpler and more predictable approach than the event system and works nicely
+with PSR-7 middleware. Due to the use of promises, the middleware system is
+also asynchronous.
+
+v5:
+
+```php
+use GuzzleHttp\Event\BeforeEvent;
+$client = new GuzzleHttp\Client();
+// Get the emitter and listen to the before event.
+$client->getEmitter()->on('before', function (BeforeEvent $e) {
+    // Guzzle v5 events relied on mutation
+    $e->getRequest()->setHeader('X-Foo', 'Bar');
+});
+```
+
+v6:
+
+In v6, you can modify the request before it is sent using the `mapRequest`
+middleware. The idiomatic way in v6 to modify the request/response lifecycle is
+to setup a handler middleware stack up front and inject the handler into a
+client.
+
+```php
+use GuzzleHttp\Middleware;
+// Create a handler stack that has all of the default middlewares attached
+$handler = GuzzleHttp\HandlerStack::create();
+// Push the handler onto the handler stack
+$handler->push(Middleware::mapRequest(function (RequestInterface $request) {
+    // Notice that we have to return a request object
+    return $request->withHeader('X-Foo', 'Bar');
+}));
+// Inject the handler into the client
+$client = new GuzzleHttp\Client(['handler' => $handler]);
+```
+
+## POST Requests
+
+This version added the [`form_params`](http://guzzle.readthedocs.org/en/latest/request-options.html#form_params)
+and `multipart` request options. `form_params` is an associative array of
+strings or array of strings and is used to serialize an
+`application/x-www-form-urlencoded` POST request. The
+[`multipart`](http://guzzle.readthedocs.org/en/latest/request-options.html#multipart)
+option is now used to send a multipart/form-data POST request.
+
+`GuzzleHttp\Post\PostFile` has been removed. Use the `multipart` option to add
+POST files to a multipart/form-data request.
+
+The `body` option no longer accepts an array to send POST requests. Please use
+`multipart` or `form_params` instead.
+
+The `base_url` option has been renamed to `base_uri`.
+
+4.x to 5.0
+----------
+
+## Rewritten Adapter Layer
+
+Guzzle now uses [RingPHP](http://ringphp.readthedocs.org/en/latest) to send
+HTTP requests. The `adapter` option in a `GuzzleHttp\Client` constructor
+is still supported, but it has now been renamed to `handler`. Instead of
+passing a `GuzzleHttp\Adapter\AdapterInterface`, you must now pass a PHP
+`callable` that follows the RingPHP specification.
+
+## Removed Fluent Interfaces
+
+[Fluent interfaces were removed](http://ocramius.github.io/blog/fluent-interfaces-are-evil)
+from the following classes:
+
+- `GuzzleHttp\Collection`
+- `GuzzleHttp\Url`
+- `GuzzleHttp\Query`
+- `GuzzleHttp\Post\PostBody`
+- `GuzzleHttp\Cookie\SetCookie`
+
+## Removed functions.php
+
+Removed "functions.php", so that Guzzle is truly PSR-4 compliant. The following
+functions can be used as replacements.
+
+- `GuzzleHttp\json_decode` -> `GuzzleHttp\Utils::jsonDecode`
+- `GuzzleHttp\get_path` -> `GuzzleHttp\Utils::getPath`
+- `GuzzleHttp\Utils::setPath` -> `GuzzleHttp\set_path`
+- `GuzzleHttp\Pool::batch` -> `GuzzleHttp\batch`. This function is, however,
+  deprecated in favor of using `GuzzleHttp\Pool::batch()`.
+
+The "procedural" global client has been removed with no replacement (e.g.,
+`GuzzleHttp\get()`, `GuzzleHttp\post()`, etc.). Use a `GuzzleHttp\Client`
+object as a replacement.
+
+## `throwImmediately` has been removed
+
+The concept of "throwImmediately" has been removed from exceptions and error
+events. This control mechanism was used to stop a transfer of concurrent
+requests from completing. This can now be handled by throwing the exception or
+by cancelling a pool of requests or each outstanding future request
+individually.
+
+## headers event has been removed
+
+Removed the "headers" event. This event was only useful for changing the
+body a response once the headers of the response were known. You can implement
+a similar behavior in a number of ways. One example might be to use a
+FnStream that has access to the transaction being sent. For example, when the
+first byte is written, you could check if the response headers match your
+expectations, and if so, change the actual stream body that is being
+written to.
+
+## Updates to HTTP Messages
+
+Removed the `asArray` parameter from
+`GuzzleHttp\Message\MessageInterface::getHeader`. If you want to get a header
+value as an array, then use the newly added `getHeaderAsArray()` method of
+`MessageInterface`. This change makes the Guzzle interfaces compatible with
+the PSR-7 interfaces.
+
+3.x to 4.0
+----------
+
+## Overarching changes:
+
+- Now requires PHP 5.4 or greater.
+- No longer requires cURL to send requests.
+- Guzzle no longer wraps every exception it throws. Only exceptions that are
+  recoverable are now wrapped by Guzzle.
+- Various namespaces have been removed or renamed.
+- No longer requiring the Symfony EventDispatcher. A custom event dispatcher
+  based on the Symfony EventDispatcher is
+  now utilized in `GuzzleHttp\Event\EmitterInterface` (resulting in significant
+  speed and functionality improvements).
+
+Changes per Guzzle 3.x namespace are described below.
+
+## Batch
+
+The `Guzzle\Batch` namespace has been removed. This is best left to
+third-parties to implement on top of Guzzle's core HTTP library.
+
+## Cache
+
+The `Guzzle\Cache` namespace has been removed. (Todo: No suitable replacement
+has been implemented yet, but hoping to utilize a PSR cache interface).
+
+## Common
+
+- Removed all of the wrapped exceptions. It's better to use the standard PHP
+  library for unrecoverable exceptions.
+- `FromConfigInterface` has been removed.
+- `Guzzle\Common\Version` has been removed. The VERSION constant can be found
+  at `GuzzleHttp\ClientInterface::VERSION`.
+
+### Collection
+
+- `getAll` has been removed. Use `toArray` to convert a collection to an array.
+- `inject` has been removed.
+- `keySearch` has been removed.
+- `getPath` no longer supports wildcard expressions. Use something better like
+  JMESPath for this.
+- `setPath` now supports appending to an existing array via the `[]` notation.
+
+### Events
+
+Guzzle no longer requires Symfony's EventDispatcher component. Guzzle now uses
+`GuzzleHttp\Event\Emitter`.
+
+- `Symfony\Component\EventDispatcher\EventDispatcherInterface` is replaced by
+  `GuzzleHttp\Event\EmitterInterface`.
+- `Symfony\Component\EventDispatcher\EventDispatcher` is replaced by
+  `GuzzleHttp\Event\Emitter`.
+- `Symfony\Component\EventDispatcher\Event` is replaced by
+  `GuzzleHttp\Event\Event`, and Guzzle now has an EventInterface in
+  `GuzzleHttp\Event\EventInterface`.
+- `AbstractHasDispatcher` has moved to a trait, `HasEmitterTrait`, and
+  `HasDispatcherInterface` has moved to `HasEmitterInterface`. Retrieving the
+  event emitter of a request, client, etc. now uses the `getEmitter` method
+  rather than the `getDispatcher` method.
+
+#### Emitter
+
+- Use the `once()` method to add a listener that automatically removes itself
+  the first time it is invoked.
+- Use the `listeners()` method to retrieve a list of event listeners rather than
+  the `getListeners()` method.
+- Use `emit()` instead of `dispatch()` to emit an event from an emitter.
+- Use `attach()` instead of `addSubscriber()` and `detach()` instead of
+  `removeSubscriber()`.
+
+```php
+$mock = new Mock();
+// 3.x
+$request->getEventDispatcher()->addSubscriber($mock);
+$request->getEventDispatcher()->removeSubscriber($mock);
+// 4.x
+$request->getEmitter()->attach($mock);
+$request->getEmitter()->detach($mock);
+```
+
+Use the `on()` method to add a listener rather than the `addListener()` method.
+
+```php
+// 3.x
+$request->getEventDispatcher()->addListener('foo', function (Event $event) { /* ... */ } );
+// 4.x
+$request->getEmitter()->on('foo', function (Event $event, $name) { /* ... */ } );
+```
+
+## Http
+
+### General changes
+
+- The cacert.pem certificate has been moved to `src/cacert.pem`.
+- Added the concept of adapters that are used to transfer requests over the
+  wire.
+- Simplified the event system.
+- Sending requests in parallel is still possible, but batching is no longer a
+  concept of the HTTP layer. Instead, you must use the `complete` and `error`
+  events to asynchronously manage parallel request transfers.
+- `Guzzle\Http\Url` has moved to `GuzzleHttp\Url`.
+- `Guzzle\Http\QueryString` has moved to `GuzzleHttp\Query`.
+- QueryAggregators have been rewritten so that they are simply callable
+  functions.
+- `GuzzleHttp\StaticClient` has been removed. Use the functions provided in
+  `functions.php` for an easy to use static client instance.
+- Exceptions in `GuzzleHttp\Exception` have been updated to all extend from
+  `GuzzleHttp\Exception\TransferException`.
+
+### Client
+
+Calling methods like `get()`, `post()`, `head()`, etc. no longer create and
+return a request, but rather creates a request, sends the request, and returns
+the response.
+
+```php
+// 3.0
+$request = $client->get('/');
+$response = $request->send();
+
+// 4.0
+$response = $client->get('/');
+
+// or, to mirror the previous behavior
+$request = $client->createRequest('GET', '/');
+$response = $client->send($request);
+```
+
+`GuzzleHttp\ClientInterface` has changed.
+
+- The `send` method no longer accepts more than one request. Use `sendAll` to
+  send multiple requests in parallel.
+- `setUserAgent()` has been removed. Use a default request option instead. You
+  could, for example, do something like:
+  `$client->setConfig('defaults/headers/User-Agent', 'Foo/Bar ' . $client::getDefaultUserAgent())`.
+- `setSslVerification()` has been removed. Use default request options instead,
+  like `$client->setConfig('defaults/verify', true)`.
+
+`GuzzleHttp\Client` has changed.
+
+- The constructor now accepts only an associative array. You can include a
+  `base_url` string or array to use a URI template as the base URL of a client.
+  You can also specify a `defaults` key that is an associative array of default
+  request options. You can pass an `adapter` to use a custom adapter,
+  `batch_adapter` to use a custom adapter for sending requests in parallel, or
+  a `message_factory` to change the factory used to create HTTP requests and
+  responses.
+- The client no longer emits a `client.create_request` event.
+- Creating requests with a client no longer automatically utilize a URI
+  template. You must pass an array into a creational method (e.g.,
+  `createRequest`, `get`, `put`, etc.) in order to expand a URI template.
+
+### Messages
+
+Messages no longer have references to their counterparts (i.e., a request no
+longer has a reference to it's response, and a response no loger has a
+reference to its request). This association is now managed through a
+`GuzzleHttp\Adapter\TransactionInterface` object. You can get references to
+these transaction objects using request events that are emitted over the
+lifecycle of a request.
+
+#### Requests with a body
+
+- `GuzzleHttp\Message\EntityEnclosingRequest` and
+  `GuzzleHttp\Message\EntityEnclosingRequestInterface` have been removed. The
+  separation between requests that contain a body and requests that do not
+  contain a body has been removed, and now `GuzzleHttp\Message\RequestInterface`
+  handles both use cases.
+- Any method that previously accepts a `GuzzleHttp\Response` object now accept a
+  `GuzzleHttp\Message\ResponseInterface`.
+- `GuzzleHttp\Message\RequestFactoryInterface` has been renamed to
+  `GuzzleHttp\Message\MessageFactoryInterface`. This interface is used to create
+  both requests and responses and is implemented in
+  `GuzzleHttp\Message\MessageFactory`.
+- POST field and file methods have been removed from the request object. You
+  must now use the methods made available to `GuzzleHttp\Post\PostBodyInterface`
+  to control the format of a POST body. Requests that are created using a
+  standard `GuzzleHttp\Message\MessageFactoryInterface` will automatically use
+  a `GuzzleHttp\Post\PostBody` body if the body was passed as an array or if
+  the method is POST and no body is provided.
+
+```php
+$request = $client->createRequest('POST', '/');
+$request->getBody()->setField('foo', 'bar');
+$request->getBody()->addFile(new PostFile('file_key', fopen('/path/to/content', 'r')));
+```
+
+#### Headers
+
+- `GuzzleHttp\Message\Header` has been removed. Header values are now simply
+  represented by an array of values or as a string. Header values are returned
+  as a string by default when retrieving a header value from a message. You can
+  pass an optional argument of `true` to retrieve a header value as an array
+  of strings instead of a single concatenated string.
+- `GuzzleHttp\PostFile` and `GuzzleHttp\PostFileInterface` have been moved to
+  `GuzzleHttp\Post`. This interface has been simplified and now allows the
+  addition of arbitrary headers.
+- Custom headers like `GuzzleHttp\Message\Header\Link` have been removed. Most
+  of the custom headers are now handled separately in specific
+  subscribers/plugins, and `GuzzleHttp\Message\HeaderValues::parseParams()` has
+  been updated to properly handle headers that contain parameters (like the
+  `Link` header).
+
+#### Responses
+
+- `GuzzleHttp\Message\Response::getInfo()` and
+  `GuzzleHttp\Message\Response::setInfo()` have been removed. Use the event
+  system to retrieve this type of information.
+- `GuzzleHttp\Message\Response::getRawHeaders()` has been removed.
+- `GuzzleHttp\Message\Response::getMessage()` has been removed.
+- `GuzzleHttp\Message\Response::calculateAge()` and other cache specific
+  methods have moved to the CacheSubscriber.
+- Header specific helper functions like `getContentMd5()` have been removed.
+  Just use `getHeader('Content-MD5')` instead.
+- `GuzzleHttp\Message\Response::setRequest()` and
+  `GuzzleHttp\Message\Response::getRequest()` have been removed. Use the event
+  system to work with request and response objects as a transaction.
+- `GuzzleHttp\Message\Response::getRedirectCount()` has been removed. Use the
+  Redirect subscriber instead.
+- `GuzzleHttp\Message\Response::isSuccessful()` and other related methods have
+  been removed. Use `getStatusCode()` instead.
+
+#### Streaming responses
+
+Streaming requests can now be created by a client directly, returning a
+`GuzzleHttp\Message\ResponseInterface` object that contains a body stream
+referencing an open PHP HTTP stream.
+
+```php
+// 3.0
+use Guzzle\Stream\PhpStreamRequestFactory;
+$request = $client->get('/');
+$factory = new PhpStreamRequestFactory();
+$stream = $factory->fromRequest($request);
+$data = $stream->read(1024);
+
+// 4.0
+$response = $client->get('/', ['stream' => true]);
+// Read some data off of the stream in the response body
+$data = $response->getBody()->read(1024);
+```
+
+#### Redirects
+
+The `configureRedirects()` method has been removed in favor of a
+`allow_redirects` request option.
+
+```php
+// Standard redirects with a default of a max of 5 redirects
+$request = $client->createRequest('GET', '/', ['allow_redirects' => true]);
+
+// Strict redirects with a custom number of redirects
+$request = $client->createRequest('GET', '/', [
+    'allow_redirects' => ['max' => 5, 'strict' => true]
+]);
+```
+
+#### EntityBody
+
+EntityBody interfaces and classes have been removed or moved to
+`GuzzleHttp\Stream`. All classes and interfaces that once required
+`GuzzleHttp\EntityBodyInterface` now require
+`GuzzleHttp\Stream\StreamInterface`. Creating a new body for a request no
+longer uses `GuzzleHttp\EntityBody::factory` but now uses
+`GuzzleHttp\Stream\Stream::factory` or even better:
+`GuzzleHttp\Stream\create()`.
+
+- `Guzzle\Http\EntityBodyInterface` is now `GuzzleHttp\Stream\StreamInterface`
+- `Guzzle\Http\EntityBody` is now `GuzzleHttp\Stream\Stream`
+- `Guzzle\Http\CachingEntityBody` is now `GuzzleHttp\Stream\CachingStream`
+- `Guzzle\Http\ReadLimitEntityBody` is now `GuzzleHttp\Stream\LimitStream`
+- `Guzzle\Http\IoEmittyinEntityBody` has been removed.
+
+#### Request lifecycle events
+
+Requests previously submitted a large number of requests. The number of events
+emitted over the lifecycle of a request has been significantly reduced to make
+it easier to understand how to extend the behavior of a request. All events
+emitted during the lifecycle of a request now emit a custom
+`GuzzleHttp\Event\EventInterface` object that contains context providing
+methods and a way in which to modify the transaction at that specific point in
+time (e.g., intercept the request and set a response on the transaction).
+
+- `request.before_send` has been renamed to `before` and now emits a
+  `GuzzleHttp\Event\BeforeEvent`
+- `request.complete` has been renamed to `complete` and now emits a
+  `GuzzleHttp\Event\CompleteEvent`.
+- `request.sent` has been removed. Use `complete`.
+- `request.success` has been removed. Use `complete`.
+- `error` is now an event that emits a `GuzzleHttp\Event\ErrorEvent`.
+- `request.exception` has been removed. Use `error`.
+- `request.receive.status_line` has been removed.
+- `curl.callback.progress` has been removed. Use a custom `StreamInterface` to
+  maintain a status update.
+- `curl.callback.write` has been removed. Use a custom `StreamInterface` to
+  intercept writes.
+- `curl.callback.read` has been removed. Use a custom `StreamInterface` to
+  intercept reads.
+
+`headers` is a new event that is emitted after the response headers of a
+request have been received before the body of the response is downloaded. This
+event emits a `GuzzleHttp\Event\HeadersEvent`.
+
+You can intercept a request and inject a response using the `intercept()` event
+of a `GuzzleHttp\Event\BeforeEvent`, `GuzzleHttp\Event\CompleteEvent`, and
+`GuzzleHttp\Event\ErrorEvent` event.
+
+See: http://docs.guzzlephp.org/en/latest/events.html
+
+## Inflection
+
+The `Guzzle\Inflection` namespace has been removed. This is not a core concern
+of Guzzle.
+
+## Iterator
+
+The `Guzzle\Iterator` namespace has been removed.
+
+- `Guzzle\Iterator\AppendIterator`, `Guzzle\Iterator\ChunkedIterator`, and
+  `Guzzle\Iterator\MethodProxyIterator` are nice, but not a core requirement of
+  Guzzle itself.
+- `Guzzle\Iterator\FilterIterator` is no longer needed because an equivalent
+  class is shipped with PHP 5.4.
+- `Guzzle\Iterator\MapIterator` is not really needed when using PHP 5.5 because
+  it's easier to just wrap an iterator in a generator that maps values.
+
+For a replacement of these iterators, see https://github.com/nikic/iter
+
+## Log
+
+The LogPlugin has moved to https://github.com/guzzle/log-subscriber. The
+`Guzzle\Log` namespace has been removed. Guzzle now relies on
+`Psr\Log\LoggerInterface` for all logging. The MessageFormatter class has been
+moved to `GuzzleHttp\Subscriber\Log\Formatter`.
+
+## Parser
+
+The `Guzzle\Parser` namespace has been removed. This was previously used to
+make it possible to plug in custom parsers for cookies, messages, URI
+templates, and URLs; however, this level of complexity is not needed in Guzzle
+so it has been removed.
+
+- Cookie: Cookie parsing logic has been moved to
+  `GuzzleHttp\Cookie\SetCookie::fromString`.
+- Message: Message parsing logic for both requests and responses has been moved
+  to `GuzzleHttp\Message\MessageFactory::fromMessage`. Message parsing is only
+  used in debugging or deserializing messages, so it doesn't make sense for
+  Guzzle as a library to add this level of complexity to parsing messages.
+- UriTemplate: URI template parsing has been moved to
+  `GuzzleHttp\UriTemplate`. The Guzzle library will automatically use the PECL
+  URI template library if it is installed.
+- Url: URL parsing is now performed in `GuzzleHttp\Url::fromString` (previously
+  it was `Guzzle\Http\Url::factory()`). If custom URL parsing is necessary,
+  then developers are free to subclass `GuzzleHttp\Url`.
+
+## Plugin
+
+The `Guzzle\Plugin` namespace has been renamed to `GuzzleHttp\Subscriber`.
+Several plugins are shipping with the core Guzzle library under this namespace.
+
+- `GuzzleHttp\Subscriber\Cookie`: Replaces the old CookiePlugin. Cookie jar
+  code has moved to `GuzzleHttp\Cookie`.
+- `GuzzleHttp\Subscriber\History`: Replaces the old HistoryPlugin.
+- `GuzzleHttp\Subscriber\HttpError`: Throws errors when a bad HTTP response is
+  received.
+- `GuzzleHttp\Subscriber\Mock`: Replaces the old MockPlugin.
+- `GuzzleHttp\Subscriber\Prepare`: Prepares the body of a request just before
+  sending. This subscriber is attached to all requests by default.
+- `GuzzleHttp\Subscriber\Redirect`: Replaces the RedirectPlugin.
+
+The following plugins have been removed (third-parties are free to re-implement
+these if needed):
+
+- `GuzzleHttp\Plugin\Async` has been removed.
+- `GuzzleHttp\Plugin\CurlAuth` has been removed.
+- `GuzzleHttp\Plugin\ErrorResponse\ErrorResponsePlugin` has been removed. This
+  functionality should instead be implemented with event listeners that occur
+  after normal response parsing occurs in the guzzle/command package.
+
+The following plugins are not part of the core Guzzle package, but are provided
+in separate repositories:
+
+- `Guzzle\Http\Plugin\BackoffPlugin` has been rewritten to be much simpler
+  to build custom retry policies using simple functions rather than various
+  chained classes. See: https://github.com/guzzle/retry-subscriber
+- `Guzzle\Http\Plugin\Cache\CachePlugin` has moved to
+  https://github.com/guzzle/cache-subscriber
+- `Guzzle\Http\Plugin\Log\LogPlugin` has moved to
+  https://github.com/guzzle/log-subscriber
+- `Guzzle\Http\Plugin\Md5\Md5Plugin` has moved to
+  https://github.com/guzzle/message-integrity-subscriber
+- `Guzzle\Http\Plugin\Mock\MockPlugin` has moved to
+  `GuzzleHttp\Subscriber\MockSubscriber`.
+- `Guzzle\Http\Plugin\Oauth\OauthPlugin` has moved to
+  https://github.com/guzzle/oauth-subscriber
+
+## Service
+
+The service description layer of Guzzle has moved into two separate packages:
+
+- http://github.com/guzzle/command Provides a high level abstraction over web
+  services by representing web service operations using commands.
+- http://github.com/guzzle/guzzle-services Provides an implementation of
+  guzzle/command that provides request serialization and response parsing using
+  Guzzle service descriptions.
+
+## Stream
+
+Stream have moved to a separate package available at
+https://github.com/guzzle/streams.
+
+`Guzzle\Stream\StreamInterface` has been given a large update to cleanly take
+on the responsibilities of `Guzzle\Http\EntityBody` and
+`Guzzle\Http\EntityBodyInterface` now that they have been removed. The number
+of methods implemented by the `StreamInterface` has been drastically reduced to
+allow developers to more easily extend and decorate stream behavior.
+
+## Removed methods from StreamInterface
+
+- `getStream` and `setStream` have been removed to better encapsulate streams.
+- `getMetadata` and `setMetadata` have been removed in favor of
+  `GuzzleHttp\Stream\MetadataStreamInterface`.
+- `getWrapper`, `getWrapperData`, `getStreamType`, and `getUri` have all been
+  removed. This data is accessible when
+  using streams that implement `GuzzleHttp\Stream\MetadataStreamInterface`.
+- `rewind` has been removed. Use `seek(0)` for a similar behavior.
+
+## Renamed methods
+
+- `detachStream` has been renamed to `detach`.
+- `feof` has been renamed to `eof`.
+- `ftell` has been renamed to `tell`.
+- `readLine` has moved from an instance method to a static class method of
+  `GuzzleHttp\Stream\Stream`.
+
+## Metadata streams
+
+`GuzzleHttp\Stream\MetadataStreamInterface` has been added to denote streams
+that contain additional metadata accessible via `getMetadata()`.
+`GuzzleHttp\Stream\StreamInterface::getMetadata` and
+`GuzzleHttp\Stream\StreamInterface::setMetadata` have been removed.
+
+## StreamRequestFactory
+
+The entire concept of the StreamRequestFactory has been removed. The way this
+was used in Guzzle 3 broke the actual interface of sending streaming requests
+(instead of getting back a Response, you got a StreamInterface). Streaming
+PHP requests are now implemented through the `GuzzleHttp\Adapter\StreamAdapter`.
+
+3.6 to 3.7
+----------
+
+### Deprecations
+
+- You can now enable E_USER_DEPRECATED warnings to see if you are using any deprecated methods.:
+
+```php
+\Guzzle\Common\Version::$emitWarnings = true;
+```
+
+The following APIs and options have been marked as deprecated:
+
+- Marked `Guzzle\Http\Message\Request::isResponseBodyRepeatable()` as deprecated. Use `$request->getResponseBody()->isRepeatable()` instead.
+- Marked `Guzzle\Http\Message\Request::canCache()` as deprecated. Use `Guzzle\Plugin\Cache\DefaultCanCacheStrategy->canCacheRequest()` instead.
+- Marked `Guzzle\Http\Message\Request::canCache()` as deprecated. Use `Guzzle\Plugin\Cache\DefaultCanCacheStrategy->canCacheRequest()` instead.
+- Marked `Guzzle\Http\Message\Request::setIsRedirect()` as deprecated. Use the HistoryPlugin instead.
+- Marked `Guzzle\Http\Message\Request::isRedirect()` as deprecated. Use the HistoryPlugin instead.
+- Marked `Guzzle\Cache\CacheAdapterFactory::factory()` as deprecated
+- Marked `Guzzle\Service\Client::enableMagicMethods()` as deprecated. Magic methods can no longer be disabled on a Guzzle\Service\Client.
+- Marked `Guzzle\Parser\Url\UrlParser` as deprecated. Just use PHP's `parse_url()` and percent encode your UTF-8.
+- Marked `Guzzle\Common\Collection::inject()` as deprecated.
+- Marked `Guzzle\Plugin\CurlAuth\CurlAuthPlugin` as deprecated. Use
+  `$client->getConfig()->setPath('request.options/auth', array('user', 'pass', 'Basic|Digest|NTLM|Any'));` or
+  `$client->setDefaultOption('auth', array('user', 'pass', 'Basic|Digest|NTLM|Any'));`
+
+3.7 introduces `request.options` as a parameter for a client configuration and as an optional argument to all creational
+request methods. When paired with a client's configuration settings, these options allow you to specify default settings
+for various aspects of a request. Because these options make other previous configuration options redundant, several
+configuration options and methods of a client and AbstractCommand have been deprecated.
+
+- Marked `Guzzle\Service\Client::getDefaultHeaders()` as deprecated. Use `$client->getDefaultOption('headers')`.
+- Marked `Guzzle\Service\Client::setDefaultHeaders()` as deprecated. Use `$client->setDefaultOption('headers/{header_name}', 'value')`.
+- Marked 'request.params' for `Guzzle\Http\Client` as deprecated. Use `$client->setDefaultOption('params/{param_name}', 'value')`
+- Marked 'command.headers', 'command.response_body' and 'command.on_complete' as deprecated for AbstractCommand. These will work through Guzzle 4.0
+
+        $command = $client->getCommand('foo', array(
+            'command.headers' => array('Test' => '123'),
+            'command.response_body' => '/path/to/file'
+        ));
+
+        // Should be changed to:
+
+        $command = $client->getCommand('foo', array(
+            'command.request_options' => array(
+                'headers' => array('Test' => '123'),
+                'save_as' => '/path/to/file'
+            )
+        ));
+
+### Interface changes
+
+Additions and changes (you will need to update any implementations or subclasses you may have created):
+
+- Added an `$options` argument to the end of the following methods of `Guzzle\Http\ClientInterface`:
+  createRequest, head, delete, put, patch, post, options, prepareRequest
+- Added an `$options` argument to the end of `Guzzle\Http\Message\Request\RequestFactoryInterface::createRequest()`
+- Added an `applyOptions()` method to `Guzzle\Http\Message\Request\RequestFactoryInterface`
+- Changed `Guzzle\Http\ClientInterface::get($uri = null, $headers = null, $body = null)` to
+  `Guzzle\Http\ClientInterface::get($uri = null, $headers = null, $options = array())`. You can still pass in a
+  resource, string, or EntityBody into the $options parameter to specify the download location of the response.
+- Changed `Guzzle\Common\Collection::__construct($data)` to no longer accepts a null value for `$data` but a
+  default `array()`
+- Added `Guzzle\Stream\StreamInterface::isRepeatable`
+- Made `Guzzle\Http\Client::expandTemplate` and `getUriTemplate` protected methods.
+
+The following methods were removed from interfaces. All of these methods are still available in the concrete classes
+that implement them, but you should update your code to use alternative methods:
+
+- Removed `Guzzle\Http\ClientInterface::setDefaultHeaders(). Use
+  `$client->getConfig()->setPath('request.options/headers/{header_name}', 'value')`. or
+  `$client->getConfig()->setPath('request.options/headers', array('header_name' => 'value'))` or
+  `$client->setDefaultOption('headers/{header_name}', 'value')`. or
+  `$client->setDefaultOption('headers', array('header_name' => 'value'))`.
+- Removed `Guzzle\Http\ClientInterface::getDefaultHeaders(). Use `$client->getConfig()->getPath('request.options/headers')`.
+- Removed `Guzzle\Http\ClientInterface::expandTemplate()`. This is an implementation detail.
+- Removed `Guzzle\Http\ClientInterface::setRequestFactory()`. This is an implementation detail.
+- Removed `Guzzle\Http\ClientInterface::getCurlMulti()`. This is a very specific implementation detail.
+- Removed `Guzzle\Http\Message\RequestInterface::canCache`. Use the CachePlugin.
+- Removed `Guzzle\Http\Message\RequestInterface::setIsRedirect`. Use the HistoryPlugin.
+- Removed `Guzzle\Http\Message\RequestInterface::isRedirect`. Use the HistoryPlugin.
+
+### Cache plugin breaking changes
+
+- CacheKeyProviderInterface and DefaultCacheKeyProvider are no longer used. All of this logic is handled in a
+  CacheStorageInterface. These two objects and interface will be removed in a future version.
+- Always setting X-cache headers on cached responses
+- Default cache TTLs are now handled by the CacheStorageInterface of a CachePlugin
+- `CacheStorageInterface::cache($key, Response $response, $ttl = null)` has changed to `cache(RequestInterface
+  $request, Response $response);`
+- `CacheStorageInterface::fetch($key)` has changed to `fetch(RequestInterface $request);`
+- `CacheStorageInterface::delete($key)` has changed to `delete(RequestInterface $request);`
+- Added `CacheStorageInterface::purge($url)`
+- `DefaultRevalidation::__construct(CacheKeyProviderInterface $cacheKey, CacheStorageInterface $cache, CachePlugin
+  $plugin)` has changed to `DefaultRevalidation::__construct(CacheStorageInterface $cache,
+  CanCacheStrategyInterface $canCache = null)`
+- Added `RevalidationInterface::shouldRevalidate(RequestInterface $request, Response $response)`
+
+3.5 to 3.6
+----------
+
+* Mixed casing of headers are now forced to be a single consistent casing across all values for that header.
+* Messages internally use a HeaderCollection object to delegate handling case-insensitive header resolution
+* Removed the whole changedHeader() function system of messages because all header changes now go through addHeader().
+  For example, setHeader() first removes the header using unset on a HeaderCollection and then calls addHeader().
+  Keeping the Host header and URL host in sync is now handled by overriding the addHeader method in Request.
+* Specific header implementations can be created for complex headers. When a message creates a header, it uses a
+  HeaderFactory which can map specific headers to specific header classes. There is now a Link header and
+  CacheControl header implementation.
+* Moved getLinks() from Response to just be used on a Link header object.
+
+If you previously relied on Guzzle\Http\Message\Header::raw(), then you will need to update your code to use the
+HeaderInterface (e.g. toArray(), getAll(), etc.).
+
+### Interface changes
+
+* Removed from interface: Guzzle\Http\ClientInterface::setUriTemplate
+* Removed from interface: Guzzle\Http\ClientInterface::setCurlMulti()
+* Removed Guzzle\Http\Message\Request::receivedRequestHeader() and implemented this functionality in
+  Guzzle\Http\Curl\RequestMediator
+* Removed the optional $asString parameter from MessageInterface::getHeader(). Just cast the header to a string.
+* Removed the optional $tryChunkedTransfer option from Guzzle\Http\Message\EntityEnclosingRequestInterface
+* Removed the $asObjects argument from Guzzle\Http\Message\MessageInterface::getHeaders()
+
+### Removed deprecated functions
+
+* Removed Guzzle\Parser\ParserRegister::get(). Use getParser()
+* Removed Guzzle\Parser\ParserRegister::set(). Use registerParser().
+
+### Deprecations
+
+* The ability to case-insensitively search for header values
+* Guzzle\Http\Message\Header::hasExactHeader
+* Guzzle\Http\Message\Header::raw. Use getAll()
+* Deprecated cache control specific methods on Guzzle\Http\Message\AbstractMessage. Use the CacheControl header object
+  instead.
+
+### Other changes
+
+* All response header helper functions return a string rather than mixing Header objects and strings inconsistently
+* Removed cURL blacklist support. This is no longer necessary now that Expect, Accept, etc. are managed by Guzzle
+  directly via interfaces
+* Removed the injecting of a request object onto a response object. The methods to get and set a request still exist
+  but are a no-op until removed.
+* Most classes that used to require a `Guzzle\Service\Command\CommandInterface` typehint now request a
+  `Guzzle\Service\Command\ArrayCommandInterface`.
+* Added `Guzzle\Http\Message\RequestInterface::startResponse()` to the RequestInterface to handle injecting a response
+  on a request while the request is still being transferred
+* `Guzzle\Service\Command\CommandInterface` now extends from ToArrayInterface and ArrayAccess
+
+3.3 to 3.4
+----------
+
+Base URLs of a client now follow the rules of http://tools.ietf.org/html/rfc3986#section-5.2.2 when merging URLs.
+
+3.2 to 3.3
+----------
+
+### Response::getEtag() quote stripping removed
+
+`Guzzle\Http\Message\Response::getEtag()` no longer strips quotes around the ETag response header
+
+### Removed `Guzzle\Http\Utils`
+
+The `Guzzle\Http\Utils` class was removed. This class was only used for testing.
+
+### Stream wrapper and type
+
+`Guzzle\Stream\Stream::getWrapper()` and `Guzzle\Stream\Stream::getStreamType()` are no longer converted to lowercase.
+
+### curl.emit_io became emit_io
+
+Emitting IO events from a RequestMediator is now a parameter that must be set in a request's curl options using the
+'emit_io' key. This was previously set under a request's parameters using 'curl.emit_io'
+
+3.1 to 3.2
+----------
+
+### CurlMulti is no longer reused globally
+
+Before 3.2, the same CurlMulti object was reused globally for each client. This can cause issue where plugins added
+to a single client can pollute requests dispatched from other clients.
+
+If you still wish to reuse the same CurlMulti object with each client, then you can add a listener to the
+ServiceBuilder's `service_builder.create_client` event to inject a custom CurlMulti object into each client as it is
+created.
+
+```php
+$multi = new Guzzle\Http\Curl\CurlMulti();
+$builder = Guzzle\Service\Builder\ServiceBuilder::factory('/path/to/config.json');
+$builder->addListener('service_builder.create_client', function ($event) use ($multi) {
+    $event['client']->setCurlMulti($multi);
+}
+});
+```
+
+### No default path
+
+URLs no longer have a default path value of '/' if no path was specified.
+
+Before:
+
+```php
+$request = $client->get('http://www.foo.com');
+echo $request->getUrl();
+// >> http://www.foo.com/
+```
+
+After:
+
+```php
+$request = $client->get('http://www.foo.com');
+echo $request->getUrl();
+// >> http://www.foo.com
+```
+
+### Less verbose BadResponseException
+
+The exception message for `Guzzle\Http\Exception\BadResponseException` no longer contains the full HTTP request and
+response information. You can, however, get access to the request and response object by calling `getRequest()` or
+`getResponse()` on the exception object.
+
+### Query parameter aggregation
+
+Multi-valued query parameters are no longer aggregated using a callback function. `Guzzle\Http\Query` now has a
+setAggregator() method that accepts a `Guzzle\Http\QueryAggregator\QueryAggregatorInterface` object. This object is
+responsible for handling the aggregation of multi-valued query string variables into a flattened hash.
+
+2.8 to 3.x
+----------
+
+### Guzzle\Service\Inspector
+
+Change `\Guzzle\Service\Inspector::fromConfig` to `\Guzzle\Common\Collection::fromConfig`
+
+**Before**
+
+```php
+use Guzzle\Service\Inspector;
+
+class YourClient extends \Guzzle\Service\Client
+{
+    public static function factory($config = array())
+    {
+        $default = array();
+        $required = array('base_url', 'username', 'api_key');
+        $config = Inspector::fromConfig($config, $default, $required);
+
+        $client = new self(
+            $config->get('base_url'),
+            $config->get('username'),
+            $config->get('api_key')
+        );
+        $client->setConfig($config);
+

+### Guzzle\Common\Inflection\Inflector
+
+Namespace is now `Guzzle\Inflection\Inflector`
+
+### Guzzle\Http\Plugin
+
+Namespace is now `Guzzle\Plugin`. Many other changes occur within this namespace and are detailed in their own sections below.
+
+### Guzzle\Http\Plugin\LogPlugin and Guzzle\Common\Log
+
+Now `Guzzle\Plugin\Log\LogPlugin` and `Guzzle\Log` respectively.
+
+**Before**
+
+```php
+use Guzzle\Common\Log\ClosureLogAdapter;
+use Guzzle\Http\Plugin\LogPlugin;
+
+/** @var \Guzzle\Http\Client */
+$client;
+
+// $verbosity is an integer indicating desired message verbosity level

+use Guzzle\Log\MessageFormatter;
+use Guzzle\Plugin\Log\LogPlugin;
+
+/** @var \Guzzle\Http\Client */
+$client;
+
+// $format is a string indicating desired message format -- @see MessageFormatter
+$client->addSubscriber(new LogPlugin(new ClosureLogAdapter(function($m) { echo $m; }, $format = MessageFormatter::DEBUG_FORMAT);
+```
+
+### Guzzle\Http\Plugin\CurlAuthPlugin
+
+Now `Guzzle\Plugin\CurlAuth\CurlAuthPlugin`.
+
+### Guzzle\Http\Plugin\ExponentialBackoffPlugin
+
+Now `Guzzle\Plugin\Backoff\BackoffPlugin`, and other changes.
+
+**Before**
+
+```php
+use Guzzle\Http\Plugin\ExponentialBackoffPlugin;
+
+$backoffPlugin = new ExponentialBackoffPlugin($maxRetries, array_merge(
+        ExponentialBackoffPlugin::getDefaultFailureCodes(), array(429)
+    ));
+
+$client->addSubscriber($backoffPlugin);
+```
+
+**After**
+
+```php
+use Guzzle\Plugin\Backoff\BackoffPlugin;
+use Guzzle\Plugin\Backoff\HttpBackoffStrategy;
+
+// Use convenient factory method instead -- see implementation for ideas of what
+// you can do with chaining backoff strategies
+$backoffPlugin = BackoffPlugin::getExponentialBackoff($maxRetries, array_merge(
+        HttpBackoffStrategy::getDefaultFailureCodes(), array(429)
+    ));
+$client->addSubscriber($backoffPlugin);
+```
+
+### Known Issues
+
+#### [BUG] Accept-Encoding header behavior changed unintentionally.
+
+(See #217) (Fixed in 09daeb8c666fb44499a0646d655a8ae36456575e)
+
+In version 2.8 setting the `Accept-Encoding` header would set the CURLOPT_ENCODING option, which permitted cURL to
+properly handle gzip/deflate compressed responses from the server. In versions affected by this bug this does not happen.
+See issue #217 for a workaround, or use a version containing the fix.

+# Features
+
+- [Promises/A+](https://promisesaplus.com/) implementation.
+- Promise resolution and chaining is handled iteratively, allowing for
+  "infinite" promise chaining.
+- Promises have a synchronous `wait` method.
+- Promises can be cancelled.
+- Works with any object that has a `then` function.
+- C# style async/await coroutine promises using
+  `GuzzleHttp\Promise\coroutine()`.
+
+
+# Quick start
+
+A *promise* represents the eventual result of an asynchronous operation. The
+primary way of interacting with a promise is through its `then` method, which
+registers callbacks to receive either a promise's eventual value or the reason
+why the promise cannot be fulfilled.
+
+
+## Callbacks
+
+Callbacks are registered with the `then` method by providing an optional 
+`$onFulfilled` followed by an optional `$onRejected` function.
+
+
+```php
+use GuzzleHttp\Promise\Promise;
+
+$promise = new Promise();
+$promise->then(
+    // $onFulfilled
+    function ($value) {
+        echo 'The promise was fulfilled.';
+    },
+    // $onRejected
+    function ($reason) {
+        echo 'The promise was rejected.';
+    }
+);
+```
+
+*Resolving* a promise means that you either fulfill a promise with a *value* or
+reject a promise with a *reason*. Resolving a promises triggers callbacks
+registered with the promises's `then` method. These callbacks are triggered
+only once and in the order in which they were added.
+
+
+## Resolving a promise
+
+Promises are fulfilled using the `resolve($value)` method. Resolving a promise
+with any value other than a `GuzzleHttp\Promise\RejectedPromise` will trigger
+all of the onFulfilled callbacks (resolving a promise with a rejected promise
+will reject the promise and trigger the `$onRejected` callbacks).
+
+```php
+use GuzzleHttp\Promise\Promise;
+
+$promise = new Promise();
+$promise
+    ->then(function ($value) {
+        // Return a value and don't break the chain
+        return "Hello, " . $value;
+    })
+    // This then is executed after the first then and receives the value
+    // returned from the first then.
+    ->then(function ($value) {
+        echo $value;
+    });
+
+// Resolving the promise triggers the $onFulfilled callbacks and outputs
+// "Hello, reader".
+$promise->resolve('reader.');
+```
+
+
+## Promise forwarding
+
+Promises can be chained one after the other. Each then in the chain is a new
+promise. The return value of a promise is what's forwarded to the next
+promise in the chain. Returning a promise in a `then` callback will cause the
+subsequent promises in the chain to only be fulfilled when the returned promise
+has been fulfilled. The next promise in the chain will be invoked with the
+resolved value of the promise.
+
+```php
+use GuzzleHttp\Promise\Promise;
+
+$promise = new Promise();
+$nextPromise = new Promise();
+
+$promise
+    ->then(function ($value) use ($nextPromise) {
+        echo $value;
+        return $nextPromise;
+    })
+    ->then(function ($value) {
+        echo $value;
+    });
+
+// Triggers the first callback and outputs "A"
+$promise->resolve('A');
+// Triggers the second callback and outputs "B"
+$nextPromise->resolve('B');
+```
+
+## Promise rejection
+
+When a promise is rejected, the `$onRejected` callbacks are invoked with the
+rejection reason.
+
+```php
+use GuzzleHttp\Promise\Promise;
+
+$promise = new Promise();
+$promise->then(null, function ($reason) {
+    echo $reason;
+});
+
+$promise->reject('Error!');
+// Outputs "Error!"
+```
+
+## Rejection forwarding
+
+If an exception is thrown in an `$onRejected` callback, subsequent
+`$onRejected` callbacks are invoked with the thrown exception as the reason.
+
+```php
+use GuzzleHttp\Promise\Promise;
+
+$promise = new Promise();
+$promise->then(null, function ($reason) {
+    throw new \Exception($reason);
+})->then(null, function ($reason) {
+    assert($reason->getMessage() === 'Error!');
+});
+
+$promise->reject('Error!');
+```
+
+You can also forward a rejection down the promise chain by returning a
+`GuzzleHttp\Promise\RejectedPromise` in either an `$onFulfilled` or
+`$onRejected` callback.
+
+```php
+use GuzzleHttp\Promise\Promise;
+use GuzzleHttp\Promise\RejectedPromise;
+
+$promise = new Promise();
+$promise->then(null, function ($reason) {
+    return new RejectedPromise($reason);
+})->then(null, function ($reason) {
+    assert($reason === 'Error!');
+});
+
+$promise->reject('Error!');
+```
+
+If an exception is not thrown in a `$onRejected` callback and the callback
+does not return a rejected promise, downstream `$onFulfilled` callbacks are
+invoked using the value returned from the `$onRejected` callback.
+
+```php
+use GuzzleHttp\Promise\Promise;
+use GuzzleHttp\Promise\RejectedPromise;
+
+$promise = new Promise();
+$promise
+    ->then(null, function ($reason) {
+        return "It's ok";
+    })
+    ->then(function ($value) {
+        assert($value === "It's ok");
+    });
+
+$promise->reject('Error!');
+```
+
+# Synchronous wait
+
+You can synchronously force promises to complete using a promise's `wait`
+method. When creating a promise, you can provide a wait function that is used
+to synchronously force a promise to complete. When a wait function is invoked
+it is expected to deliver a value to the promise or reject the promise. If the
+wait function does not deliver a value, then an exception is thrown. The wait
+function provided to a promise constructor is invoked when the `wait` function
+of the promise is called.
+
+```php
+$promise = new Promise(function () use (&$promise) {
+    $promise->resolve('foo');
+});
+
+// Calling wait will return the value of the promise.
+echo $promise->wait(); // outputs "foo"
+```
+
+If an exception is encountered while invoking the wait function of a promise,
+the promise is rejected with the exception and the exception is thrown.
+
+```php
+$promise = new Promise(function () use (&$promise) {
+    throw new \Exception('foo');
+});
+
+$promise->wait(); // throws the exception.
+```
+
+Calling `wait` on a promise that has been fulfilled will not trigger the wait
+function. It will simply return the previously resolved value.
+
+```php
+$promise = new Promise(function () { die('this is not called!'); });
+$promise->resolve('foo');
+echo $promise->wait(); // outputs "foo"
+```
+
+Calling `wait` on a promise that has been rejected will throw an exception. If
+the rejection reason is an instance of `\Exception` the reason is thrown.
+Otherwise, a `GuzzleHttp\Promise\RejectionException` is thrown and the reason
+can be obtained by calling the `getReason` method of the exception.
+
+```php
+$promise = new Promise();
+$promise->reject('foo');
+$promise->wait();
+```
+
+> PHP Fatal error:  Uncaught exception 'GuzzleHttp\Promise\RejectionException' with message 'The promise was rejected with value: foo'
+
+
+## Unwrapping a promise
+
+When synchronously waiting on a promise, you are joining the state of the
+promise into the current state of execution (i.e., return the value of the
+promise if it was fulfilled or throw an exception if it was rejected). This is
+called "unwrapping" the promise. Waiting on a promise will by default unwrap
+the promise state.
+
+You can force a promise to resolve and *not* unwrap the state of the promise
+by passing `false` to the first argument of the `wait` function:
+
+```php
+$promise = new Promise();
+$promise->reject('foo');
+// This will not throw an exception. It simply ensures the promise has
+// been resolved.
+$promise->wait(false);
+```
+
+When unwrapping a promise, the resolved value of the promise will be waited
+upon until the unwrapped value is not a promise. This means that if you resolve
+promise A with a promise B and unwrap promise A, the value returned by the
+wait function will be the value delivered to promise B.
+
+**Note**: when you do not unwrap the promise, no value is returned.
+
+
+# Cancellation
+
+You can cancel a promise that has not yet been fulfilled using the `cancel()`
+method of a promise. When creating a promise you can provide an optional
+cancel function that when invoked cancels the action of computing a resolution
+of the promise.
+
+
+# API
+
+
+## Promise
+
+When creating a promise object, you can provide an optional `$waitFn` and
+`$cancelFn`. `$waitFn` is a function that is invoked with no arguments and is
+expected to resolve the promise. `$cancelFn` is a function with no arguments
+that is expected to cancel the computation of a promise. It is invoked when the
+`cancel()` method of a promise is called.
+
+```php
+use GuzzleHttp\Promise\Promise;
+
+$promise = new Promise(
+    function () use (&$promise) {
+        $promise->resolve('waited');
+    },
+    function () {
+        // do something that will cancel the promise computation (e.g., close
+        // a socket, cancel a database query, etc...)
+    }
+);
+
+assert('waited' === $promise->wait());
+```
+
+A promise has the following methods:
+
+- `then(callable $onFulfilled, callable $onRejected) : PromiseInterface`
+  
+  Appends fulfillment and rejection handlers to the promise, and returns a new promise resolving to the return value of the called handler.
+
+- `otherwise(callable $onRejected) : PromiseInterface`
+  
+  Appends a rejection handler callback to the promise, and returns a new promise resolving to the return value of the callback if it is called, or to its original fulfillment value if the promise is instead fulfilled.
+
+- `wait($unwrap = true) : mixed`
+
+  Synchronously waits on the promise to complete.
+  
+  `$unwrap` controls whether or not the value of the promise is returned for a
+  fulfilled promise or if an exception is thrown if the promise is rejected.
+  This is set to `true` by default.
+
+- `cancel()`
+
+  Attempts to cancel the promise if possible. The promise being cancelled and
+  the parent most ancestor that has not yet been resolved will also be
+  cancelled. Any promises waiting on the cancelled promise to resolve will also
+  be cancelled.
+
+- `getState() : string`
+
+  Returns the state of the promise. One of `pending`, `fulfilled`, or
+  `rejected`.
+
+- `resolve($value)`
+
+  Fulfills the promise with the given `$value`.
+
+- `reject($reason)`
+
+  Rejects the promise with the given `$reason`.
+
+
+## FulfilledPromise
+
+A fulfilled promise can be created to represent a promise that has been
+fulfilled.
+
+```php
+use GuzzleHttp\Promise\FulfilledPromise;
+
+$promise = new FulfilledPromise('value');
+
+// Fulfilled callbacks are immediately invoked.
+$promise->then(function ($value) {
+    echo $value;
+});
+```
+
+
+## RejectedPromise
+
+A rejected promise can be created to represent a promise that has been
+rejected.
+
+```php
+use GuzzleHttp\Promise\RejectedPromise;
+
+$promise = new RejectedPromise('Error');
+
+// Rejected callbacks are immediately invoked.
+$promise->then(null, function ($reason) {
+    echo $reason;
+});
+```
+
+
+# Promise interop
+
+This library works with foreign promises that have a `then` method. This means
+you can use Guzzle promises with [React promises](https://github.com/reactphp/promise)
+for example. When a foreign promise is returned inside of a then method
+callback, promise resolution will occur recursively.
+
+```php
+// Create a React promise
+$deferred = new React\Promise\Deferred();
+$reactPromise = $deferred->promise();
+
+// Create a Guzzle promise that is fulfilled with a React promise.
+$guzzlePromise = new \GuzzleHttp\Promise\Promise();
+$guzzlePromise->then(function ($value) use ($reactPromise) {
+    // Do something something with the value...
+    // Return the React promise
+    return $reactPromise;
+});
+```
+
+Please note that wait and cancel chaining is no longer possible when forwarding
+a foreign promise. You will need to wrap a third-party promise with a Guzzle
+promise in order to utilize wait and cancel functions with foreign promises.
+
+
+## Event Loop Integration
+
+In order to keep the stack size constant, Guzzle promises are resolved
+asynchronously using a task queue. When waiting on promises synchronously, the
+task queue will be automatically run to ensure that the blocking promise and
+any forwarded promises are resolved. When using promises asynchronously in an
+event loop, you will need to run the task queue on each tick of the loop. If
+you do not run the task queue, then promises will not be resolved.
+
+You can run the task queue using the `run()` method of the global task queue
+instance.
+
+```php
+// Get the global task queue
+$queue = \GuzzleHttp\Promise\queue();
+$queue->run();
+```
+
+For example, you could use Guzzle promises with React using a periodic timer:
+
+```php
+$loop = React\EventLoop\Factory::create();
+$loop->addPeriodicTimer(0, [$queue, 'run']);
+```
+
+*TODO*: Perhaps adding a `futureTick()` on each tick would be faster?
+
+
+# Implementation notes
+
+
+## Promise resolution and chaining is handled iteratively
+
+By shuffling pending handlers from one owner to another, promises are
+resolved iteratively, allowing for "infinite" then chaining.
+
+```php
+<?php
+require 'vendor/autoload.php';
+
+use GuzzleHttp\Promise\Promise;
+
+$parent = new Promise();
+$p = $parent;
+
+for ($i = 0; $i < 1000; $i++) {
+    $p = $p->then(function ($v) {
+        // The stack size remains constant (a good thing)
+        echo xdebug_get_stack_depth() . ', ';
+        return $v + 1;
+    });
+}
+
+$parent->resolve(0);
+var_dump($p->wait()); // int(1000)
+
+```
+
+When a promise is fulfilled or rejected with a non-promise value, the promise
+then takes ownership of the handlers of each child promise and delivers values
+down the chain without using recursion.
+
+When a promise is resolved with another promise, the original promise transfers
+all of its pending handlers to the new promise. When the new promise is
+eventually resolved, all of the pending handlers are delivered the forwarded
+value.
+
+
+## A promise is the deferred.
+
+Some promise libraries implement promises using a deferred object to represent
+a computation and a promise object to represent the delivery of the result of
+the computation. This is a nice separation of computation and delivery because
+consumers of the promise cannot modify the value that will be eventually
+delivered.
+
+One side effect of being able to implement promise resolution and chaining
+iteratively is that you need to be able for one promise to reach into the state
+of another promise to shuffle around ownership of handlers. In order to achieve
+this without making the handlers of a promise publicly mutable, a promise is
+also the deferred value, allowing promises of the same parent class to reach
+into and modify the private properties of promises of the same type. While this
+does allow consumers of the value to modify the resolution or rejection of the
+deferred, it is a small price to pay for keeping the stack size constant.
+
+```php
+$promise = new Promise();
+$promise->then(function ($value) { echo $value; });
+// The promise is the deferred value, so you can deliver a value to it.
+$promise->resolve('foo');
+// prints "foo"
+```

+* Reverted BC break by reintroducing behavior to automagically fix a URI with a
+  relative path and an authority by adding a leading slash to the path. It's only
+  deprecated now.
+* Added triggering of silenced deprecation warnings.
+
+## 1.4.0 - 2017-02-21
+
+* Fix `Stream::read` when length parameter <= 0.
+* `copy_to_stream` reads bytes in chunks instead of `maxLen` into memory.
+* Fix `ServerRequest::getUriFromGlobals` when `Host` header contains port.
+* Ensure `ServerRequest::getUriFromGlobals` returns a URI in absolute form.
+* Allow `parse_response` to parse a response without delimiting space and reason.
+* Ensure each URI modification results in a valid URI according to PSR-7 discussions.
+  Invalid modifications will throw an exception instead of returning a wrong URI or
+  doing some magic.
+  - `(new Uri)->withPath('foo')->withHost('example.com')` will throw an exception
+    because the path of a URI with an authority must start with a slash "/" or be empty
+  - `(new Uri())->withScheme('http')` will return `'http://localhost'`
+* Fix compatibility of URIs with `file` scheme and empty host.
+* Added common URI utility methods based on RFC 3986 (see documentation in the readme):
+  - `Uri::isDefaultPort`
+  - `Uri::isAbsolute`
+  - `Uri::isNetworkPathReference`
+  - `Uri::isAbsolutePathReference`
+  - `Uri::isRelativePathReference`
+  - `Uri::isSameDocumentReference`
+  - `Uri::composeComponents`
+  - `UriNormalizer::normalize`
+  - `UriNormalizer::isEquivalent`
+  - `UriResolver::relativize`
+* Deprecated `Uri::resolve` in favor of `UriResolver::resolve`
+* Deprecated `Uri::removeDotSegments` in favor of `UriResolver::removeDotSegments`
+
+## 1.3.1 - 2016-06-25
+
+* Fix `Uri::__toString` for network path references, e.g. `//example.org`.
+* Fix missing lowercase normalization for host.
+* Fix handling of URI components in case they are `'0'` in a lot of places,
+  e.g. as a user info password.
+* Fix `Uri::withAddedHeader` to correctly merge headers with different case.
+* Fix trimming of header values in `Uri::withAddedHeader`. Header values may
+  be surrounded by whitespace which should be ignored according to RFC 7230
+  Section 3.2.4. This does not apply to header names.
+* Fix `Uri::withAddedHeader` with an array of header values.
+* Fix `Uri::resolve` when base path has no slash and handling of fragment.
+* Fix handling of encoding in `Uri::with(out)QueryValue` so one can pass the
+  key/value both in encoded as well as decoded form to those methods. This is
+  consistent with withPath, withQuery etc.
+* Fix `ServerRequest::withoutAttribute` when attribute value is null.
+
+## 1.3.0 - 2016-04-13
+
+* Added remaining interfaces needed for full PSR7 compatibility
+  (ServerRequestInterface, UploadedFileInterface, etc.).
+* Added support for stream_for from scalars.
+* Can now extend Uri.
+* Fixed a bug in validating request methods by making it more permissive.
+
+## 1.2.3 - 2016-02-18
+
+* Fixed support in `GuzzleHttp\Psr7\CachingStream` for seeking forward on remote
+  streams, which can sometimes return fewer bytes than requested with `fread`.
+* Fixed handling of gzipped responses with FNAME headers.
+
+## 1.2.2 - 2016-01-22
+
+* Added support for URIs without any authority.
+* Added support for HTTP 451 'Unavailable For Legal Reasons.'
+* Added support for using '0' as a filename.
+* Added support for including non-standard ports in Host headers.
+
+## 1.2.1 - 2015-11-02
+
+* Now supporting negative offsets when seeking to SEEK_END.
+
+## 1.2.0 - 2015-08-15
+
+* Body as `"0"` is now properly added to a response.
+* Now allowing forward seeking in CachingStream.
+* Now properly parsing HTTP requests that contain proxy targets in
+  `parse_request`.
+* functions.php is now conditionally required.
+* user-info is no longer dropped when resolving URIs.
+
+## 1.1.0 - 2015-06-24
+
+* URIs can now be relative.
+* `multipart/form-data` headers are now overridden case-insensitively.
+* URI paths no longer encode the following characters because they are allowed
+  in URIs: "(", ")", "*", "!", "'"
+* A port is no longer added to a URI when the scheme is missing and no port is
+  present.
+
+## 1.0.0 - 2015-05-19
+
+Initial release.
+
+Currently unsupported:
+

+# PSR-7 Message Implementation
+
+This repository contains a full [PSR-7](http://www.php-fig.org/psr/psr-7/)
+message implementation, several stream decorators, and some helpful
+functionality like query string parsing.
+
+
+[![Build Status](https://travis-ci.org/guzzle/psr7.svg?branch=master)](https://travis-ci.org/guzzle/psr7)
+
+
+# Stream implementation
+
+This package comes with a number of stream implementations and stream
+decorators.
+
+
+## AppendStream
+
+`GuzzleHttp\Psr7\AppendStream`
+
+Reads from multiple streams, one after the other.
+
+```php
+use GuzzleHttp\Psr7;
+
+$a = Psr7\stream_for('abc, ');
+$b = Psr7\stream_for('123.');
+$composed = new Psr7\AppendStream([$a, $b]);
+
+$composed->addStream(Psr7\stream_for(' Above all listen to me'));
+
+echo $composed; // abc, 123. Above all listen to me.
+```
+
+
+## BufferStream
+
+`GuzzleHttp\Psr7\BufferStream`
+
+Provides a buffer stream that can be written to fill a buffer, and read
+from to remove bytes from the buffer.
+
+This stream returns a "hwm" metadata value that tells upstream consumers
+what the configured high water mark of the stream is, or the maximum
+preferred size of the buffer.
+
+```php
+use GuzzleHttp\Psr7;
+
+// When more than 1024 bytes are in the buffer, it will begin returning
+// false to writes. This is an indication that writers should slow down.
+$buffer = new Psr7\BufferStream(1024);
+```
+
+
+## CachingStream
+
+The CachingStream is used to allow seeking over previously read bytes on
+non-seekable streams. This can be useful when transferring a non-seekable
+entity body fails due to needing to rewind the stream (for example, resulting
+from a redirect). Data that is read from the remote stream will be buffered in
+a PHP temp stream so that previously read bytes are cached first in memory,
+then on disk.
+
+```php
+use GuzzleHttp\Psr7;
+
+$original = Psr7\stream_for(fopen('http://www.google.com', 'r'));
+$stream = new Psr7\CachingStream($original);
+
+$stream->read(1024);
+echo $stream->tell();
+// 1024
+
+$stream->seek(0);
+echo $stream->tell();
+// 0
+```
+
+
+## DroppingStream
+
+`GuzzleHttp\Psr7\DroppingStream`
+
+Stream decorator that begins dropping data once the size of the underlying
+stream becomes too full.
+
+```php
+use GuzzleHttp\Psr7;
+
+// Create an empty stream
+$stream = Psr7\stream_for();
+
+// Start dropping data when the stream has more than 10 bytes
+$dropping = new Psr7\DroppingStream($stream, 10);
+
+$dropping->write('01234567890123456789');
+echo $stream; // 0123456789
+```
+
+
+## FnStream
+
+`GuzzleHttp\Psr7\FnStream`
+
+Compose stream implementations based on a hash of functions.
+
+Allows for easy testing and extension of a provided stream without needing
+to create a concrete class for a simple extension point.
+
+```php
+
+use GuzzleHttp\Psr7;
+
+$stream = Psr7\stream_for('hi');
+$fnStream = Psr7\FnStream::decorate($stream, [
+    'rewind' => function () use ($stream) {
+        echo 'About to rewind - ';
+        $stream->rewind();
+        echo 'rewound!';
+    }
+]);
+
+$fnStream->rewind();
+// Outputs: About to rewind - rewound!
+```
+
+
+## InflateStream
+
+`GuzzleHttp\Psr7\InflateStream`
+
+Uses PHP's zlib.inflate filter to inflate deflate or gzipped content.
+
+This stream decorator skips the first 10 bytes of the given stream to remove
+the gzip header, converts the provided stream to a PHP stream resource,
+then appends the zlib.inflate filter. The stream is then converted back
+to a Guzzle stream resource to be used as a Guzzle stream.
+
+
+## LazyOpenStream
+
+`GuzzleHttp\Psr7\LazyOpenStream`
+
+Lazily reads or writes to a file that is opened only after an IO operation
+take place on the stream.
+
+```php
+use GuzzleHttp\Psr7;
+
+$stream = new Psr7\LazyOpenStream('/path/to/file', 'r');
+// The file has not yet been opened...
+
+echo $stream->read(10);
+// The file is opened and read from only when needed.
+```
+
+
+## LimitStream
+
+`GuzzleHttp\Psr7\LimitStream`
+
+LimitStream can be used to read a subset or slice of an existing stream object.
+This can be useful for breaking a large file into smaller pieces to be sent in
+chunks (e.g. Amazon S3's multipart upload API).
+
+```php
+use GuzzleHttp\Psr7;
+
+$original = Psr7\stream_for(fopen('/tmp/test.txt', 'r+'));
+echo $original->getSize();
+// >>> 1048576
+
+// Limit the size of the body to 1024 bytes and start reading from byte 2048
+$stream = new Psr7\LimitStream($original, 1024, 2048);
+echo $stream->getSize();
+// >>> 1024
+echo $stream->tell();
+// >>> 0
+```
+
+
+## MultipartStream
+
+`GuzzleHttp\Psr7\MultipartStream`
+
+Stream that when read returns bytes for a streaming multipart or
+multipart/form-data stream.
+
+
+## NoSeekStream
+
+`GuzzleHttp\Psr7\NoSeekStream`
+
+NoSeekStream wraps a stream and does not allow seeking.
+
+```php
+use GuzzleHttp\Psr7;
+
+$original = Psr7\stream_for('foo');
+$noSeek = new Psr7\NoSeekStream($original);
+
+echo $noSeek->read(3);
+// foo
+var_export($noSeek->isSeekable());
+// false
+$noSeek->seek(0);
+var_export($noSeek->read(3));
+// NULL
+```
+
+
+## PumpStream
+
+`GuzzleHttp\Psr7\PumpStream`
+
+Provides a read only stream that pumps data from a PHP callable.
+
+When invoking the provided callable, the PumpStream will pass the amount of
+data requested to read to the callable. The callable can choose to ignore
+this value and return fewer or more bytes than requested. Any extra data
+returned by the provided callable is buffered internally until drained using
+the read() function of the PumpStream. The provided callable MUST return
+false when there is no more data to read.
+
+
+## Implementing stream decorators
+
+Creating a stream decorator is very easy thanks to the
+`GuzzleHttp\Psr7\StreamDecoratorTrait`. This trait provides methods that
+implement `Psr\Http\Message\StreamInterface` by proxying to an underlying
+stream. Just `use` the `StreamDecoratorTrait` and implement your custom
+methods.
+
+For example, let's say we wanted to call a specific function each time the last
+byte is read from a stream. This could be implemented by overriding the
+`read()` method.
+
+```php
+use Psr\Http\Message\StreamInterface;
+use GuzzleHttp\Psr7\StreamDecoratorTrait;
+
+class EofCallbackStream implements StreamInterface
+{
+    use StreamDecoratorTrait;
+
+    private $callback;
+
+    public function __construct(StreamInterface $stream, callable $cb)
+    {
+        $this->stream = $stream;
+        $this->callback = $cb;
+    }
+
+    public function read($length)
+    {
+        $result = $this->stream->read($length);
+
+        // Invoke the callback when EOF is hit.
+        if ($this->eof()) {
+            call_user_func($this->callback);
+        }
+
+        return $result;
+    }
+}
+```
+
+This decorator could be added to any existing stream and used like so:
+
+```php
+use GuzzleHttp\Psr7;
+
+$original = Psr7\stream_for('foo');
+
+$eofStream = new EofCallbackStream($original, function () {
+    echo 'EOF!';
+});
+
+$eofStream->read(2);
+$eofStream->read(1);
+// echoes "EOF!"
+$eofStream->seek(0);
+$eofStream->read(3);
+// echoes "EOF!"
+```
+
+
+## PHP StreamWrapper
+
+You can use the `GuzzleHttp\Psr7\StreamWrapper` class if you need to use a
+PSR-7 stream as a PHP stream resource.
+
+Use the `GuzzleHttp\Psr7\StreamWrapper::getResource()` method to create a PHP
+stream from a PSR-7 stream.
+
+```php
+use GuzzleHttp\Psr7\StreamWrapper;
+
+$stream = GuzzleHttp\Psr7\stream_for('hello!');
+$resource = StreamWrapper::getResource($stream);
+echo fread($resource, 6); // outputs hello!
+```
+
+
+# Function API
+
+There are various functions available under the `GuzzleHttp\Psr7` namespace.
+
+
+## `function str`
+
+`function str(MessageInterface $message)`
+
+Returns the string representation of an HTTP message.
+
+```php
+$request = new GuzzleHttp\Psr7\Request('GET', 'http://example.com');
+echo GuzzleHttp\Psr7\str($request);
+```
+
+
+## `function uri_for`
+
+`function uri_for($uri)`
+
+This function accepts a string or `Psr\Http\Message\UriInterface` and returns a
+UriInterface for the given value. If the value is already a `UriInterface`, it
+is returned as-is.
+
+```php
+$uri = GuzzleHttp\Psr7\uri_for('http://example.com');
+assert($uri === GuzzleHttp\Psr7\uri_for($uri));
+```
+
+
+## `function stream_for`
+
+`function stream_for($resource = '', array $options = [])`
+
+Create a new stream based on the input type.
+
+Options is an associative array that can contain the following keys:
+
+* - metadata: Array of custom metadata.
+* - size: Size of the stream.
+
+This method accepts the following `$resource` types:
+
+- `Psr\Http\Message\StreamInterface`: Returns the value as-is.
+- `string`: Creates a stream object that uses the given string as the contents.
+- `resource`: Creates a stream object that wraps the given PHP stream resource.
+- `Iterator`: If the provided value implements `Iterator`, then a read-only
+  stream object will be created that wraps the given iterable. Each time the
+  stream is read from, data from the iterator will fill a buffer and will be
+  continuously called until the buffer is equal to the requested read size.
+  Subsequent read calls will first read from the buffer and then call `next`
+  on the underlying iterator until it is exhausted.
+- `object` with `__toString()`: If the object has the `__toString()` method,
+  the object will be cast to a string and then a stream will be returned that
+  uses the string value.
+- `NULL`: When `null` is passed, an empty stream object is returned.
+- `callable` When a callable is passed, a read-only stream object will be
+  created that invokes the given callable. The callable is invoked with the
+  number of suggested bytes to read. The callable can return any number of
+  bytes, but MUST return `false` when there is no more data to return. The
+  stream object that wraps the callable will invoke the callable until the
+  number of requested bytes are available. Any additional bytes will be
+  buffered and used in subsequent reads.
+
+```php
+$stream = GuzzleHttp\Psr7\stream_for('foo');
+$stream = GuzzleHttp\Psr7\stream_for(fopen('/path/to/file', 'r'));
+
+$generator function ($bytes) {
+    for ($i = 0; $i < $bytes; $i++) {
+        yield ' ';
+    }
+}
+
+$stream = GuzzleHttp\Psr7\stream_for($generator(100));
+```
+
+
+## `function parse_header`
+
+`function parse_header($header)`
+
+Parse an array of header values containing ";" separated data into an array of
+associative arrays representing the header key value pair data of the header.
+When a parameter does not contain a value, but just contains a key, this
+function will inject a key with a '' string value.
+
+
+## `function normalize_header`
+
+`function normalize_header($header)`
+
+Converts an array of header values that may contain comma separated headers
+into an array of headers with no comma separated values.
+
+
+## `function modify_request`
+
+`function modify_request(RequestInterface $request, array $changes)`
+
+Clone and modify a request with the given changes. This method is useful for
+reducing the number of clones needed to mutate a message.
+
+The changes can be one of:
+
+- method: (string) Changes the HTTP method.
+- set_headers: (array) Sets the given headers.
+- remove_headers: (array) Remove the given headers.
+- body: (mixed) Sets the given body.
+- uri: (UriInterface) Set the URI.
+- query: (string) Set the query string value of the URI.
+- version: (string) Set the protocol version.
+
+
+## `function rewind_body`
+
+`function rewind_body(MessageInterface $message)`
+
+Attempts to rewind a message body and throws an exception on failure. The body
+of the message will only be rewound if a call to `tell()` returns a value other
+than `0`.
+
+
+## `function try_fopen`
+
+`function try_fopen($filename, $mode)`
+
+Safely opens a PHP stream resource using a filename.
+
+When fopen fails, PHP normally raises a warning. This function adds an error
+handler that checks for errors and throws an exception instead.
+
+
+## `function copy_to_string`
+
+`function copy_to_string(StreamInterface $stream, $maxLen = -1)`
+
+Copy the contents of a stream into a string until the given number of bytes
+have been read.
+
+
+## `function copy_to_stream`
+
+`function copy_to_stream(StreamInterface $source, StreamInterface $dest, $maxLen = -1)`
+
+Copy the contents of a stream into another stream until the given number of
+bytes have been read.
+
+
+## `function hash`
+
+`function hash(StreamInterface $stream, $algo, $rawOutput = false)`
+
+Calculate a hash of a Stream. This method reads the entire stream to calculate
+a rolling hash (based on PHP's hash_init functions).
+
+
+## `function readline`
+
+`function readline(StreamInterface $stream, $maxLength = null)`
+
+Read a line from the stream up to the maximum allowed buffer length.
+
+
+## `function parse_request`
+
+`function parse_request($message)`
+
+Parses a request message string into a request object.
+
+
+## `function parse_response`
+
+`function parse_response($message)`
+
+Parses a response message string into a response object.
+
+
+## `function parse_query`
+
+`function parse_query($str, $urlEncoding = true)`
+
+Parse a query string into an associative array.
+
+If multiple values are found for the same key, the value of that key value pair
+will become an array. This function does not parse nested PHP style arrays into
+an associative array (e.g., `foo[a]=1&foo[b]=2` will be parsed into
+`['foo[a]' => '1', 'foo[b]' => '2']`).
+
+
+## `function build_query`
+
+`function build_query(array $params, $encoding = PHP_QUERY_RFC3986)`
+
+Build a query string from an array of key value pairs.
+
+This function can use the return value of parse_query() to build a query string.
+This function does not modify the provided keys when an array is encountered
+(like http_build_query would).
+
+
+## `function mimetype_from_filename`
+
+`function mimetype_from_filename($filename)`
+
+Determines the mimetype of a file by looking at its extension.
+
+
+## `function mimetype_from_extension`
+
+`function mimetype_from_extension($extension)`
+
+Maps a file extensions to a mimetype.
+
+
+# Additional URI Methods
+
+Aside from the standard `Psr\Http\Message\UriInterface` implementation in form of the `GuzzleHttp\Psr7\Uri` class,
+this library also provides additional functionality when working with URIs as static methods.
+
+## URI Types
+
+An instance of `Psr\Http\Message\UriInterface` can either be an absolute URI or a relative reference.
+An absolute URI has a scheme. A relative reference is used to express a URI relative to another URI,
+the base URI. Relative references can be divided into several forms according to
+[RFC 3986 Section 4.2](https://tools.ietf.org/html/rfc3986#section-4.2):
+
+- network-path references, e.g. `//example.com/path`
+- absolute-path references, e.g. `/path`
+- relative-path references, e.g. `subpath`
+
+The following methods can be used to identify the type of the URI.
+
+### `GuzzleHttp\Psr7\Uri::isAbsolute`
+
+`public static function isAbsolute(UriInterface $uri): bool`
+
+Whether the URI is absolute, i.e. it has a scheme.
+
+### `GuzzleHttp\Psr7\Uri::isNetworkPathReference`
+
+`public static function isNetworkPathReference(UriInterface $uri): bool`
+
+Whether the URI is a network-path reference. A relative reference that begins with two slash characters is
+termed an network-path reference.
+
+### `GuzzleHttp\Psr7\Uri::isAbsolutePathReference`
+
+`public static function isAbsolutePathReference(UriInterface $uri): bool`
+
+Whether the URI is a absolute-path reference. A relative reference that begins with a single slash character is
+termed an absolute-path reference.
+
+### `GuzzleHttp\Psr7\Uri::isRelativePathReference`
+
+`public static function isRelativePathReference(UriInterface $uri): bool`
+
+Whether the URI is a relative-path reference. A relative reference that does not begin with a slash character is
+termed a relative-path reference.
+
+### `GuzzleHttp\Psr7\Uri::isSameDocumentReference`
+
+`public static function isSameDocumentReference(UriInterface $uri, UriInterface $base = null): bool`
+
+Whether the URI is a same-document reference. A same-document reference refers to a URI that is, aside from its
+fragment component, identical to the base URI. When no base URI is given, only an empty URI reference
+(apart from its fragment) is considered a same-document reference.
+
+## URI Components
+
+Additional methods to work with URI components.
+
+### `GuzzleHttp\Psr7\Uri::isDefaultPort`
+
+`public static function isDefaultPort(UriInterface $uri): bool`
+
+Whether the URI has the default port of the current scheme. `Psr\Http\Message\UriInterface::getPort` may return null
+or the standard port. This method can be used independently of the implementation.
+
+### `GuzzleHttp\Psr7\Uri::composeComponents`
+
+`public static function composeComponents($scheme, $authority, $path, $query, $fragment): string`
+
+Composes a URI reference string from its various components according to
+[RFC 3986 Section 5.3](https://tools.ietf.org/html/rfc3986#section-5.3). Usually this method does not need to be called
+manually but instead is used indirectly via `Psr\Http\Message\UriInterface::__toString`.
+
+### `GuzzleHttp\Psr7\Uri::fromParts`
+
+`public static function fromParts(array $parts): UriInterface`
+
+Creates a URI from a hash of [`parse_url`](http://php.net/manual/en/function.parse-url.php) components.
+
+
+### `GuzzleHttp\Psr7\Uri::withQueryValue`
+
+`public static function withQueryValue(UriInterface $uri, $key, $value): UriInterface`
+
+Creates a new URI with a specific query string value. Any existing query string values that exactly match the
+provided key are removed and replaced with the given key value pair. A value of null will set the query string
+key without a value, e.g. "key" instead of "key=value".
+
+
+### `GuzzleHttp\Psr7\Uri::withoutQueryValue`
+
+`public static function withoutQueryValue(UriInterface $uri, $key): UriInterface`
+
+Creates a new URI with a specific query string value removed. Any existing query string values that exactly match the
+provided key are removed.
+
+## Reference Resolution
+
+`GuzzleHttp\Psr7\UriResolver` provides methods to resolve a URI reference in the context of a base URI according
+to [RFC 3986 Section 5](https://tools.ietf.org/html/rfc3986#section-5). This is for example also what web browsers
+do when resolving a link in a website based on the current request URI.
+
+### `GuzzleHttp\Psr7\UriResolver::resolve`
+
+`public static function resolve(UriInterface $base, UriInterface $rel): UriInterface`
+
+Converts the relative URI into a new URI that is resolved against the base URI.
+
+### `GuzzleHttp\Psr7\UriResolver::removeDotSegments`
+
+`public static function removeDotSegments(string $path): string`
+
+Removes dot segments from a path and returns the new path according to
+[RFC 3986 Section 5.2.4](https://tools.ietf.org/html/rfc3986#section-5.2.4).
+
+### `GuzzleHttp\Psr7\UriResolver::relativize`
+
+`public static function relativize(UriInterface $base, UriInterface $target): UriInterface`
+
+Returns the target URI as a relative reference from the base URI. This method is the counterpart to resolve():
+
+```php
+(string) $target === (string) UriResolver::resolve($base, UriResolver::relativize($base, $target))
+```
+
+One use-case is to use the current request URI as base URI and then generate relative links in your documents
+to reduce the document size or offer self-contained downloadable document archives.
+
+```php
+$base = new Uri('http://example.com/a/b/');
+echo UriResolver::relativize($base, new Uri('http://example.com/a/b/c'));  // prints 'c'.
+echo UriResolver::relativize($base, new Uri('http://example.com/a/x/y'));  // prints '../x/y'.
+echo UriResolver::relativize($base, new Uri('http://example.com/a/b/?q')); // prints '?q'.
+echo UriResolver::relativize($base, new Uri('http://example.org/a/b/'));   // prints '//example.org/a/b/'.
+```
+
+## Normalization and Comparison
+
+`GuzzleHttp\Psr7\UriNormalizer` provides methods to normalize and compare URIs according to
+[RFC 3986 Section 6](https://tools.ietf.org/html/rfc3986#section-6).
+
+### `GuzzleHttp\Psr7\UriNormalizer::normalize`
+
+`public static function normalize(UriInterface $uri, $flags = self::PRESERVING_NORMALIZATIONS): UriInterface`
+
+Returns a normalized URI. The scheme and host component are already normalized to lowercase per PSR-7 UriInterface.
+This methods adds additional normalizations that can be configured with the `$flags` parameter which is a bitmask
+of normalizations to apply. The following normalizations are available:
+
+- `UriNormalizer::PRESERVING_NORMALIZATIONS`
+
+    Default normalizations which only include the ones that preserve semantics.
+
+- `UriNormalizer::CAPITALIZE_PERCENT_ENCODING`
+
+    All letters within a percent-encoding triplet (e.g., "%3A") are case-insensitive, and should be capitalized.
+
+    Example: `http://example.org/a%c2%b1b` → `http://example.org/a%C2%B1b`
+
+- `UriNormalizer::DECODE_UNRESERVED_CHARACTERS`
+
+    Decodes percent-encoded octets of unreserved characters. For consistency, percent-encoded octets in the ranges of
+    ALPHA (%41–%5A and %61–%7A), DIGIT (%30–%39), hyphen (%2D), period (%2E), underscore (%5F), or tilde (%7E) should
+    not be created by URI producers and, when found in a URI, should be decoded to their corresponding unreserved
+    characters by URI normalizers.
+
+    Example: `http://example.org/%7Eusern%61me/` → `http://example.org/~username/`
+
+- `UriNormalizer::CONVERT_EMPTY_PATH`
+
+    Converts the empty path to "/" for http and https URIs.
+
+    Example: `http://example.org` → `http://example.org/`
+
+- `UriNormalizer::REMOVE_DEFAULT_HOST`
+
+    Removes the default host of the given URI scheme from the URI. Only the "file" scheme defines the default host
+    "localhost". All of `file:/myfile`, `file:///myfile`, and `file://localhost/myfile` are equivalent according to
+    RFC 3986.
+
+    Example: `file://localhost/myfile` → `file:///myfile`
+
+- `UriNormalizer::REMOVE_DEFAULT_PORT`
+
+    Removes the default port of the given URI scheme from the URI.
+
+    Example: `http://example.org:80/` → `http://example.org/`
+
+- `UriNormalizer::REMOVE_DOT_SEGMENTS`
+
+    Removes unnecessary dot-segments. Dot-segments in relative-path references are not removed as it would
+    change the semantics of the URI reference.
+
+    Example: `http://example.org/../a/b/../c/./d.html` → `http://example.org/a/c/d.html`
+
+- `UriNormalizer::REMOVE_DUPLICATE_SLASHES`
+
+    Paths which include two or more adjacent slashes are converted to one. Webservers usually ignore duplicate slashes
+    and treat those URIs equivalent. But in theory those URIs do not need to be equivalent. So this normalization
+    may change the semantics. Encoded slashes (%2F) are not removed.
+
+    Example: `http://example.org//foo///bar.html` → `http://example.org/foo/bar.html`
+
+- `UriNormalizer::SORT_QUERY_PARAMETERS`
+
+    Sort query parameters with their values in alphabetical order. However, the order of parameters in a URI may be
+    significant (this is not defined by the standard). So this normalization is not safe and may change the semantics
+    of the URI.
+
+    Example: `?lang=en&article=fred` → `?article=fred&lang=en`
+
+### `GuzzleHttp\Psr7\UriNormalizer::isEquivalent`
+
+`public static function isEquivalent(UriInterface $uri1, UriInterface $uri2, $normalizations = self::PRESERVING_NORMALIZATIONS): bool`
+
+Whether two URIs can be considered equivalent. Both URIs are normalized automatically before comparison with the given
+`$normalizations` bitmask. The method also accepts relative URI references and returns true when they are equivalent.
+This of course assumes they will be resolved against the same base URI. If this is not the case, determination of
+equivalence or difference of relative references does not mean anything.

+The ReflectionDocBlock Component [![Build Status](https://secure.travis-ci.org/phpDocumentor/ReflectionDocBlock.png)](https://travis-ci.org/phpDocumentor/ReflectionDocBlock)
+================================
+
+Introduction
+------------
+
+The ReflectionDocBlock component of phpDocumentor provides a DocBlock parser
+that is 100% compatible with the [PHPDoc standard](http://phpdoc.org/docs/latest).
+
+With this component, a library can provide support for annotations via DocBlocks
+or otherwise retrieve information that is embedded in a DocBlock.
+
+Installation
+------------
+
+```bash
+composer require phpdocumentor/reflection-docblock
+```
+
+Usage
+-----
+
+In order to parse the DocBlock one needs a DocBlockFactory that can be
+instantiated using its `createInstance` factory method like this:
+
+```php
+$factory  = \phpDocumentor\Reflection\DocBlockFactory::createInstance();
+```
+
+Then we can use the `create` method of the factory to interpret the DocBlock. 
+Please note that it is also possible to provide a class that has the 
+`getDocComment()` method, such as an object of type `ReflectionClass`, the
+create method will read that if it exists.
+
+```php
+$docComment = <<<DOCCOMMENT
+/**
+ * This is an example of a summary.
+ *
+ * This is a Description. A Summary and Description are separated by either
+ * two subsequent newlines (thus a whiteline in between as can be seen in this
+ * example), or when the Summary ends with a dot (`.`) and some form of
+ * whitespace.
+ */
+DOCCOMMENT;
+
+$docblock = $factory->create($docComment);
+```
+
+The `create` method will yield an object of type `\phpDocumentor\Reflection\DocBlock`
+whose methods can be queried:
+
+```php
+// Contains the summary for this DocBlock
+$summary = $docblock->getSummary();
+
+// Contains \phpDocumentor\Reflection\DocBlock\Description object
+$description = $docblock->getDescription();
+
+// You can either cast it to string
+$description = (string) $docblock->getDescription();
+
+// Or use the render method to get a string representation of the Description.
+$description = $docblock->getDescription()->render();
+```
+
+> For more examples it would be best to review the scripts in the [`/examples` folder](/examples).

+ * Object representing to description for a DocBlock.

+ * A Description object can consist of plain text but can also include tags. A Description Formatter can then combine
+ * a body template with sprintf-style placeholders together with formatted tags in order to reconstitute a complete
+ * description text using the format that you would prefer.
+ *
+ * Because parsing a Description text can be a verbose process this is handled by the {@see DescriptionFactory}. It is
+ * thus recommended to use that to create a Description object, like this:
+ *
+ *     $description = $descriptionFactory->create('This is a {@see Description}', $context);
+ *
+ * The description factory will interpret the given body and create a body template and list of tags from them, and pass
+ * that onto the constructor if this class.
+ *
+ * > The $context variable is a class of type {@see \phpDocumentor\Reflection\Types\Context} and contains the namespace
+ * > and the namespace aliases that apply to this DocBlock. These are used by the Factory to resolve and expand partial
+ * > type names and FQSENs.
+ *
+ * If you do not want to use the DescriptionFactory you can pass a body template and tag listing like this:
+ *
+ *     $description = new Description(
+ *         'This is a %1$s',
+ *         [ new See(new Fqsen('\phpDocumentor\Reflection\DocBlock\Description')) ]
+ *     );
+ *
+ * It is generally recommended to use the Factory as that will also apply escaping rules, while the Description object
+ * is mainly responsible for rendering.

+ * @see DescriptionFactory to create a new Description.
+ * @see Description\Formatter for the formatting of the body and tags.

+TypeResolver and FqsenResolver
+==============================
+
+The specification on types in DocBlocks (PSR-5) describes various keywords and special constructs
+but also how to statically resolve the partial name of a Class into a Fully Qualified Class Name (FQCN).
+
+PSR-5 also introduces an additional way to describe deeper elements than Classes, Interfaces and Traits 
+called the Fully Qualified Structural Element Name (FQSEN). Using this it is possible to refer to methods,
+properties and class constants but also functions and global constants.
+
+This package provides two Resolvers that are capable of 
+
+1. Returning a series of Value Object for given expression while resolving any partial class names, and 
+2. Returning an FQSEN object after resolving any partial Structural Element Names into Fully Qualified Structural 
+   Element names.
+
+## Installing
+
+The easiest way to install this library is with [Composer](https://getcomposer.org) using the following command:
+
+    $ composer require phpdocumentor/type-resolver
+
+## Examples
+
+Ready to dive in and don't want to read through all that text below? Just consult the [examples](examples) folder and
+check which type of action that your want to accomplish.
+
+## On Types and Element Names
+
+This component can be used in one of two ways
+ 
+1. To resolve a Type or
+2. To resolve a Fully Qualified Structural Element Name
+ 
+The big difference between these two is in the number of things it can resolve. 
+
+The TypeResolver can resolve:
+
+- a php primitive or pseudo-primitive such as a string or void (`@var string` or `@return void`).
+- a composite such as an array of string (`@var string[]`).
+- a compound such as a string or integer (`@var string|integer`).
+- an object or interface such as the TypeResolver class (`@var TypeResolver` 
+  or `@var \phpDocumentor\Reflection\TypeResolver`)
+
+  > please note that if you want to pass partial class names that additional steps are necessary, see the 
+  > chapter `Resolving partial classes and FQSENs` for more information.
+
+Where the FqsenResolver can resolve:
+
+- Constant expressions (i.e. `@see \MyNamespace\MY_CONSTANT`)
+- Function expressions (i.e. `@see \MyNamespace\myFunction()`)
+- Class expressions (i.e. `@see \MyNamespace\MyClass`)
+- Interface expressions (i.e. `@see \MyNamespace\MyInterface`)
+- Trait expressions (i.e. `@see \MyNamespace\MyTrait`)
+- Class constant expressions (i.e. `@see \MyNamespace\MyClass::MY_CONSTANT`)
+- Property expressions (i.e. `@see \MyNamespace\MyClass::$myProperty`)
+- Method expressions (i.e. `@see \MyNamespace\MyClass::myMethod()`)
+
+## Resolving a type
+
+In order to resolve a type you will have to instantiate the class `\phpDocumentor\Reflection\TypeResolver`
+and call its `resolve` method like this:
+
+```php
+$typeResolver = new \phpDocumentor\Reflection\TypeResolver();
+$type = $typeResolver->resolve('string|integer');
+```
+
+In this example you will receive a Value Object of class `\phpDocumentor\Reflection\Types\Compound` that has two 
+elements, one of type `\phpDocumentor\Reflection\Types\String_` and one of type 
+`\phpDocumentor\Reflection\Types\Integer`.
+
+The real power of this resolver is in its capability to expand partial class names into fully qualified class names; but
+in order to do that we need an additional `\phpDocumentor\Reflection\Types\Context` class that will inform the resolver 
+in which namespace the given expression occurs and which namespace aliases (or imports) apply.
+
+## Resolving an FQSEN
+
+A Fully Qualified Structural Element Name is a reference to another element in your code bases and can be resolved using
+the `\phpDocumentor\Reflection\FqsenResolver` class' `resolve` method, like this:
+
+```php
+$fqsenResolver = new \phpDocumentor\Reflection\FqsenResolver();
+$fqsen = $fqsenResolver->resolve('\phpDocumentor\Reflection\FqsenResolver::resolve()');
+```
+
+In this example we resolve a Fully Qualified Structural Element Name (meaning that it includes the full namespace, class
+name and element name) and receive a Value Object of type `\phpDocumentor\Reflection\Fqsen`.
+
+The real power of this resolver is in its capability to expand partial element names into Fully Qualified Structural 
+Element Names; but in order to do that we need an additional `\phpDocumentor\Reflection\Types\Context` class that will 
+inform the resolver in which namespace the given expression occurs and which namespace aliases (or imports) apply.
+
+## Resolving partial Classes and Structural Element Names
+
+Perhaps the best feature of this library is that it knows how to resolve partial class names into fully qualified class 
+names.
+
+For example, you have this file:
+
+```php
+namespace My\Example;
+
+use phpDocumentor\Reflection\Types;
+
+class Classy
+{
+    /**
+     * @var Types\Context
+     * @see Classy::otherFunction()
+     */
+    public function __construct($context) {}
+    
+    public function otherFunction(){}
+}
+```
+
+Suppose that you would want to resolve (and expand) the type in the `@var` tag and the element name in the `@see` tag.
+For the resolvers to know how to expand partial names you have to provide a bit of _Context_ for them by instantiating
+a new class named `\phpDocumentor\Reflection\Types\Context` with the name of the namespace and the aliases that are in 
+play.
+
+### Creating a Context
+
+You can do this by manually creating a Context like this:
+
+```php
+$context = new \phpDocumentor\Reflection\Types\Context(
+    '\My\Example', 
+    [ 'Types' => '\phpDocumentor\Reflection\Types']
+);
+```
+
+Or by using the `\phpDocumentor\Reflection\Types\ContextFactory` to instantiate a new context based on a Reflector 
+object or by providing the namespace that you'd like to extract and the source code of the file in which the given
+type expression occurs.
+
+```php
+$contextFactory = new \phpDocumentor\Reflection\Types\ContextFactory();
+$context = $contextFactory->createFromReflector(new ReflectionMethod('\My\Example\Classy', '__construct'));
+```
+
+or
+
+```php
+$contextFactory = new \phpDocumentor\Reflection\Types\ContextFactory();
+$context = $contextFactory->createForNamespace('\My\Example', file_get_contents('My/Example/Classy.php'));
+```
+
+### Using the Context
+
+After you have obtained a Context it is just a matter of passing it along with the `resolve` method of either Resolver 
+class as second argument and the Resolvers will take this into account when resolving partial names.
+
+To obtain the resolved class name for the `@var` tag in the example above you can do:
+
+```php
+$typeResolver = new \phpDocumentor\Reflection\TypeResolver();
+$type = $typeResolver->resolve('Types\Context', $context);
+```
+
+When you do this you will receive an object of class `\phpDocumentor\Reflection\Types\Object_` for which you can call 
+the `getFqsen` method to receive a Value Object that represents the complete FQSEN. So that would be 
+`phpDocumentor\Reflection\Types\Context`.
+
+> Why is the FQSEN wrapped in another object `Object_`?
+> 
+> The resolve method of the TypeResolver only returns object with the interface `Type` and the FQSEN is a common
+> type that does not represent a Type. Also: in some cases a type can represent an "Untyped Object", meaning that it
+> is an object (signified by the `object` keyword) but does not refer to a specific element using an FQSEN.
+
+Another example is on how to resolve the FQSEN of a method as can be seen with the `@see` tag in the example above. To
+resolve that you can do the following:
+
+```php
+$fqsenResolver = new \phpDocumentor\Reflection\FqsenResolver();
+$type = $fqsenResolver->resolve('Classy::otherFunction()', $context);
+```
+
+Because Classy is a Class in the current namespace its FQSEN will have the `My\Example` namespace and by calling the 
+`resolve` method of the FQSEN Resolver you will receive an `Fqsen` object that refers to 
+`\My\Example\Classy::otherFunction()`.

+# Prophecy
+
+[![Stable release](https://poser.pugx.org/phpspec/prophecy/version.svg)](https://packagist.org/packages/phpspec/prophecy)
+[![Build Status](https://travis-ci.org/phpspec/prophecy.svg?branch=master)](https://travis-ci.org/phpspec/prophecy)
+
+Prophecy is a highly opinionated yet very powerful and flexible PHP object mocking
+framework. Though initially it was created to fulfil phpspec2 needs, it is flexible
+enough to be used inside any testing framework out there with minimal effort.
+
+## A simple example
+
+```php
+<?php
+
+class UserTest extends PHPUnit_Framework_TestCase
+{
+    private $prophet;
+
+    public function testPasswordHashing()
+    {
+        $hasher = $this->prophet->prophesize('App\Security\Hasher');
+        $user   = new App\Entity\User($hasher->reveal());
+
+        $hasher->generateHash($user, 'qwerty')->willReturn('hashed_pass');
+
+        $user->setPassword('qwerty');
+
+        $this->assertEquals('hashed_pass', $user->getPassword());
+    }
+
+    protected function setup()
+    {
+        $this->prophet = new \Prophecy\Prophet;
+    }
+
+    protected function tearDown()
+    {
+        $this->prophet->checkPredictions();
+    }
+}
+```
+
+## Installation
+
+### Prerequisites
+
+Prophecy requires PHP 5.3.3 or greater.
+
+### Setup through composer
+
+First, add Prophecy to the list of dependencies inside your `composer.json`:
+
+```json
+{
+    "require-dev": {
+        "phpspec/prophecy": "~1.0"
+    }
+}
+```
+
+Then simply install it with composer:
+
+```bash
+$> composer install --prefer-dist
+```
+
+You can read more about Composer on its [official webpage](http://getcomposer.org).
+
+## How to use it
+
+First of all, in Prophecy every word has a logical meaning, even the name of the library
+itself (Prophecy). When you start feeling that, you'll become very fluid with this
+tool.
+
+For example, Prophecy has been named that way because it concentrates on describing the future
+behavior of objects with very limited knowledge about them. But as with any other prophecy,
+those object prophecies can't create themselves - there should be a Prophet:
+
+```php
+$prophet = new Prophecy\Prophet;
+```
+
+The Prophet creates prophecies by *prophesizing* them:
+
+```php
+$prophecy = $prophet->prophesize();
+```
+
+The result of the `prophesize()` method call is a new object of class `ObjectProphecy`. Yes,
+that's your specific object prophecy, which describes how your object would behave
+in the near future. But first, you need to specify which object you're talking about,
+right?
+
+```php
+$prophecy->willExtend('stdClass');
+$prophecy->willImplement('SessionHandlerInterface');
+```
+
+There are 2 interesting calls - `willExtend` and `willImplement`. The first one tells
+object prophecy that our object should extend specific class, the second one says that
+it should implement some interface. Obviously, objects in PHP can implement multiple
+interfaces, but extend only one parent class.
+
+### Dummies
+
+Ok, now we have our object prophecy. What can we do with it? First of all, we can get
+our object *dummy* by revealing its prophecy:
+
+```php
+$dummy = $prophecy->reveal();
+```
+
+The `$dummy` variable now holds a special dummy object. Dummy objects are objects that extend
+and/or implement preset classes/interfaces by overriding all their public methods. The key
+point about dummies is that they do not hold any logic - they just do nothing. Any method
+of the dummy will always return `null` and the dummy will never throw any exceptions.
+Dummy is your friend if you don't care about the actual behavior of this double and just need
+a token object to satisfy a method typehint.
+
+You need to understand one thing - a dummy is not a prophecy. Your object prophecy is still
+assigned to `$prophecy` variable and in order to manipulate with your expectations, you
+should work with it. `$dummy` is a dummy - a simple php object that tries to fulfil your
+prophecy.
+
+### Stubs
+
+Ok, now we know how to create basic prophecies and reveal dummies from them. That's
+awesome if we don't care about our _doubles_ (objects that reflect originals)
+interactions. If we do, we need to use *stubs* or *mocks*.
+
+A stub is an object double, which doesn't have any expectations about the object behavior,
+but when put in specific environment, behaves in specific way. Ok, I know, it's cryptic,
+but bear with me for a minute. Simply put, a stub is a dummy, which depending on the called
+method signature does different things (has logic). To create stubs in Prophecy:
+
+```php
+$prophecy->read('123')->willReturn('value');
+```
+
+Oh wow. We've just made an arbitrary call on the object prophecy? Yes, we did. And this
+call returned us a new object instance of class `MethodProphecy`. Yep, that's a specific
+method with arguments prophecy. Method prophecies give you the ability to create method
+promises or predictions. We'll talk about method predictions later in the _Mocks_ section.
+
+#### Promises
+
+Promises are logical blocks, that represent your fictional methods in prophecy terms
+and they are handled by the `MethodProphecy::will(PromiseInterface $promise)` method.
+As a matter of fact, the call that we made earlier (`willReturn('value')`) is a simple
+shortcut to:
+
+```php
+$prophecy->read('123')->will(new Prophecy\Promise\ReturnPromise(array('value')));
+```
+
+This promise will cause any call to our double's `read()` method with exactly one
+argument - `'123'` to always return `'value'`. But that's only for this
+promise, there's plenty others you can use:
+
+- `ReturnPromise` or `->willReturn(1)` - returns a value from a method call
+- `ReturnArgumentPromise` or `->willReturnArgument($index)` - returns the nth method argument from call
+- `ThrowPromise` or `->willThrow($exception)` - causes the method to throw specific exception
+- `CallbackPromise` or `->will($callback)` - gives you a quick way to define your own custom logic
+
+Keep in mind, that you can always add even more promises by implementing
+`Prophecy\Promise\PromiseInterface`.
+
+#### Method prophecies idempotency
+
+Prophecy enforces same method prophecies and, as a consequence, same promises and
+predictions for the same method calls with the same arguments. This means:
+
+```php
+$methodProphecy1 = $prophecy->read('123');
+$methodProphecy2 = $prophecy->read('123');
+$methodProphecy3 = $prophecy->read('321');
+
+$methodProphecy1 === $methodProphecy2;
+$methodProphecy1 !== $methodProphecy3;
+```
+
+That's interesting, right? Now you might ask me how would you define more complex
+behaviors where some method call changes behavior of others. In PHPUnit or Mockery
+you do that by predicting how many times your method will be called. In Prophecy,
+you'll use promises for that:
+
+```php
+$user->getName()->willReturn(null);
+
+// For PHP 5.4
+$user->setName('everzet')->will(function () {
+    $this->getName()->willReturn('everzet');
+});
+
+// For PHP 5.3
+$user->setName('everzet')->will(function ($args, $user) {
+    $user->getName()->willReturn('everzet');
+});
+
+// Or
+$user->setName('everzet')->will(function ($args) use ($user) {
+    $user->getName()->willReturn('everzet');
+});
+```
+
+And now it doesn't matter how many times or in which order your methods are called.
+What matters is their behaviors and how well you faked it.
+
+#### Arguments wildcarding
+
+The previous example is awesome (at least I hope it is for you), but that's not
+optimal enough. We hardcoded `'everzet'` in our expectation. Isn't there a better
+way? In fact there is, but it involves understanding what this `'everzet'`
+actually is.
+
+You see, even if method arguments used during method prophecy creation look
+like simple method arguments, in reality they are not. They are argument token
+wildcards.  As a matter of fact, `->setName('everzet')` looks like a simple call just
+because Prophecy automatically transforms it under the hood into:
+
+```php
+$user->setName(new Prophecy\Argument\Token\ExactValueToken('everzet'));
+```
+
+Those argument tokens are simple PHP classes, that implement
+`Prophecy\Argument\Token\TokenInterface` and tell Prophecy how to compare real arguments
+with your expectations. And yes, those classnames are damn big. That's why there's a
+shortcut class `Prophecy\Argument`, which you can use to create tokens like that:
+
+```php
+use Prophecy\Argument;
+
+$user->setName(Argument::exact('everzet'));
+```
+
+`ExactValueToken` is not very useful in our case as it forced us to hardcode the username.
+That's why Prophecy comes bundled with a bunch of other tokens:
+
+- `IdenticalValueToken` or `Argument::is($value)` - checks that the argument is identical to a specific value
+- `ExactValueToken` or `Argument::exact($value)` - checks that the argument matches a specific value
+- `TypeToken` or `Argument::type($typeOrClass)` - checks that the argument matches a specific type or
+  classname
+- `ObjectStateToken` or `Argument::which($method, $value)` - checks that the argument method returns
+  a specific value
+- `CallbackToken` or `Argument::that(callback)` - checks that the argument matches a custom callback
+- `AnyValueToken` or `Argument::any()` - matches any argument
+- `AnyValuesToken` or `Argument::cetera()` - matches any arguments to the rest of the signature
+- `StringContainsToken` or `Argument::containingString($value)` - checks that the argument contains a specific string value
+
+And you can add even more by implementing `TokenInterface` with your own custom classes.
+
+So, let's refactor our initial `{set,get}Name()` logic with argument tokens:
+
+```php
+use Prophecy\Argument;
+
+$user->getName()->willReturn(null);
+
+// For PHP 5.4
+$user->setName(Argument::type('string'))->will(function ($args) {
+    $this->getName()->willReturn($args[0]);
+});
+
+// For PHP 5.3
+$user->setName(Argument::type('string'))->will(function ($args, $user) {
+    $user->getName()->willReturn($args[0]);
+});
+
+// Or
+$user->setName(Argument::type('string'))->will(function ($args) use ($user) {
+    $user->getName()->willReturn($args[0]);
+});
+```
+
+That's it. Now our `{set,get}Name()` prophecy will work with any string argument provided to it.
+We've just described how our stub object should behave, even though the original object could have
+no behavior whatsoever.
+
+One last bit about arguments now. You might ask, what happens in case of:
+
+```php
+use Prophecy\Argument;
+
+$user->getName()->willReturn(null);
+
+// For PHP 5.4
+$user->setName(Argument::type('string'))->will(function ($args) {
+    $this->getName()->willReturn($args[0]);
+});
+
+// For PHP 5.3
+$user->setName(Argument::type('string'))->will(function ($args, $user) {
+    $user->getName()->willReturn($args[0]);
+});
+
+// Or
+$user->setName(Argument::type('string'))->will(function ($args) use ($user) {
+    $user->getName()->willReturn($args[0]);
+});
+
+$user->setName(Argument::any())->will(function () {
+});
+```
+
+Nothing. Your stub will continue behaving the way it did before. That's because of how
+arguments wildcarding works. Every argument token type has a different score level, which
+wildcard then uses to calculate the final arguments match score and use the method prophecy
+promise that has the highest score. In this case, `Argument::type()` in case of success
+scores `5` and `Argument::any()` scores `3`. So the type token wins, as does the first
+`setName()` method prophecy and its promise. The simple rule of thumb - more precise token
+always wins.
+
+#### Getting stub objects
+
+Ok, now we know how to define our prophecy method promises, let's get our stub from
+it:
+
+```php
+$stub = $prophecy->reveal();
+```
+
+As you might see, the only difference between how we get dummies and stubs is that with
+stubs we describe every object conversation instead of just agreeing with `null` returns
+(object being *dummy*). As a matter of fact, after you define your first promise
+(method call), Prophecy will force you to define all the communications - it throws
+the `UnexpectedCallException` for any call you didn't describe with object prophecy before
+calling it on a stub.
+
+### Mocks
+
+Now we know how to define doubles without behavior (dummies) and doubles with behavior, but
+no expectations (stubs). What's left is doubles for which we have some expectations. These
+are called mocks and in Prophecy they look almost exactly the same as stubs, except that
+they define *predictions* instead of *promises* on method prophecies:
+
+```php
+$entityManager->flush()->shouldBeCalled();
+```
+
+#### Predictions
+
+The `shouldBeCalled()` method here assigns `CallPrediction` to our method prophecy.
+Predictions are a delayed behavior check for your prophecies. You see, during the entire lifetime
+of your doubles, Prophecy records every single call you're making against it inside your
+code. After that, Prophecy can use this collected information to check if it matches defined
+predictions. You can assign predictions to method prophecies using the
+`MethodProphecy::should(PredictionInterface $prediction)` method. As a matter of fact,
+the `shouldBeCalled()` method we used earlier is just a shortcut to:
+
+```php
+$entityManager->flush()->should(new Prophecy\Prediction\CallPrediction());
+```
+
+It checks if your method of interest (that matches both the method name and the arguments wildcard)
+was called 1 or more times. If the prediction failed then it throws an exception. When does this
+check happen? Whenever you call `checkPredictions()` on the main Prophet object:
+
+```php
+$prophet->checkPredictions();
+```
+
+In PHPUnit, you would want to put this call into the `tearDown()` method. If no predictions
+are defined, it would do nothing. So it won't harm to call it after every test.
+
+There are plenty more predictions you can play with:
+
+- `CallPrediction` or `shouldBeCalled()` - checks that the method has been called 1 or more times
+- `NoCallsPrediction` or `shouldNotBeCalled()` - checks that the method has not been called
+- `CallTimesPrediction` or `shouldBeCalledTimes($count)` - checks that the method has been called
+  `$count` times
+- `CallbackPrediction` or `should($callback)` - checks the method against your own custom callback
+
+Of course, you can always create your own custom prediction any time by implementing
+`PredictionInterface`.
+
+### Spies
+
+The last bit of awesomeness in Prophecy is out-of-the-box spies support. As I said in the previous
+section, Prophecy records every call made during the double's entire lifetime. This means
+you don't need to record predictions in order to check them. You can also do it
+manually by using the `MethodProphecy::shouldHave(PredictionInterface $prediction)` method:
+
+```php
+$em = $prophet->prophesize('Doctrine\ORM\EntityManager');
+
+$controller->createUser($em->reveal());
+
+$em->flush()->shouldHaveBeenCalled();
+```
+
+Such manipulation with doubles is called spying. And with Prophecy it just works.

+
+### Removed
+
+* The dedicated driver for HHVM, `PHP_CodeCoverage_Driver_HHVM` has been removed

+
+# PHP_CodeCoverage
+
+**PHP_CodeCoverage** is a library that provides collection, processing, and rendering functionality for PHP code coverage information.
+
+## Requirements
+
+PHP 5.3.3 is required but using the latest version of PHP is highly recommended
+
+### PHP 5
+
+[Xdebug](http://xdebug.org/) is the only source of raw code coverage data supported for PHP 5. Version 2.1.3 of Xdebug is required but using the latest version is highly recommended.
+
+### PHP 7
+
+[phpdbg](http://phpdbg.com/docs) is currently the only source of raw code coverage data supported for PHP 7. Once Xdebug has been updated for PHP 7 it, too, will be supported.
+
+### HHVM
+
+A version of HHVM that implements the Xdebug API for code coverage (`xdebug_*_code_coverage()`) is required.
+
+## Installation
+
+To add PHP_CodeCoverage as a local, per-project dependency to your project, simply add a dependency on `phpunit/php-code-coverage` to your project's `composer.json` file. Here is a minimal example of a `composer.json` file that just defines a dependency on PHP_CodeCoverage 2.0:
+
+    {
+        "require": {
+            "phpunit/php-code-coverage": "^2"
+        }
+    }
+
+## Using the PHP_CodeCoverage API
+
+```php
+<?php
+$coverage = new PHP_CodeCoverage;
+$coverage->start('<name of test>');
+
+// ...
+
+$coverage->stop();
+
+$writer = new PHP_CodeCoverage_Report_Clover;
+$writer->process($coverage, '/tmp/clover.xml');
+
+$writer = new PHP_CodeCoverage_Report_HTML;
+$writer->process($coverage, '/tmp/code-coverage-report');
+```

+To add this package as a local, per-project dependency to your project, simply add a dependency on `phpunit/php-text-template` to your project's `composer.json` file. Here is a minimal example of a `composer.json` file that just defines a dependency on Text_Template:
+
+    {
+        "require": {
+            "phpunit/php-text-template": "~1.2"
+        }

+
+# PHP_Timer
+
+Utility class for timing things, factored out of PHPUnit into a stand-alone component.
+
+## Installation
+
+You can add this library as a local, per-project dependency to your project using [Composer](https://getcomposer.org/):
+
+    composer require phpunit/php-timer
+
+If you only need this library during development, for instance to run your project's test suite, then you should add it as a development-time dependency:
+
+    composer require --dev phpunit/php-timer
+
+## Usage
+
+### Basic Timing
+
+```php
+PHP_Timer::start();
+
+// ...
+
+$time = PHP_Timer::stop();
+var_dump($time);
+
+print PHP_Timer::secondsToTimeString($time);
+```
+
+The code above yields the output below:
+
+    double(1.0967254638672E-5)
+    0 ms
+
+### Resource Consumption Since PHP Startup
+
+```php
+print PHP_Timer::resourceUsage();
+```
+
+The code above yields the output below:
+
+    Time: 0 ms, Memory: 0.50MB

+# PHPUnit_MockObject
+
+**PHPUnit_MockObject** is the default mock object library for PHPUnit.
+
+## Requirements
+
+* PHP 5.3.3 is required but using the latest version of PHP is highly recommended
+
+## Installation
+
+To add PHPUnit_MockObject as a local, per-project dependency to your project, simply add a dependency on `phpunit/phpunit-mock-objects` to your project's `composer.json` file. Here is a minimal example of a `composer.json` file that just defines a dependency on PHPUnit_MockObject 2.3:
+
+    {
+        "require": {
+            "phpunit/phpunit-mock-objects": "2.3.*"
+        }
+    }

+# Contributor Code of Conduct
+
+As contributors and maintainers of this project, and in the interest of fostering an open and welcoming community, we pledge to respect all people who contribute through reporting issues, posting feature requests, updating documentation, submitting pull requests or patches, and other activities.
+
+We are committed to making participation in this project a harassment-free experience for everyone, regardless of level of experience, gender, gender identity and expression, sexual orientation, disability, personal appearance, body size, race, ethnicity, age, religion, or nationality.
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery
+* Personal attacks
+* Trolling or insulting/derogatory comments
+* Public or private harassment
+* Publishing other's private information, such as physical or electronic
+  addresses, without explicit permission
+* Other unethical or unprofessional conduct
+
+Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, or to ban temporarily or permanently any contributor for other behaviors that they deem inappropriate, threatening, offensive, or harmful.
+
+By adopting this Code of Conduct, project maintainers commit themselves to fairly and consistently applying these principles to every aspect of managing this project. Project maintainers who do not follow or enforce the Code of Conduct may be permanently removed from the project team.
+
+This Code of Conduct applies both within project spaces and in public spaces when an individual is representing the project or its community.
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by contacting the project maintainer at sebastian@phpunit.de. All complaints will be reviewed and investigated and will result in a response that is deemed necessary and appropriate to the circumstances. Maintainers are obligated to maintain confidentiality with regard to the reporter of an incident.
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.3.0, available at [http://contributor-covenant.org/version/1/3/0/][version]

+# Contributing to PHPUnit
+
+## Contributor Code of Conduct
+
+Please note that this project is released with a [Contributor Code of Conduct](CODE_OF_CONDUCT.md). By participating in this project you agree to abide by its terms.
+
+## Workflow
+
+* Fork the project.
+* Make your bug fix or feature addition.
+* Add tests for it. This is important so we don't break it in a future version unintentionally.
+* Send a pull request. Bonus points for topic branches.
+
+Please make sure that you have [set up your user name and email address](http://git-scm.com/book/en/v2/Getting-Started-First-Time-Git-Setup) for use with Git. Strings such as `silly nick name <root@localhost>` look really stupid in the commit history of a project.
+
+Pull requests for bug fixes must be based on the current stable branch whereas pull requests for new features must be based on the `master` branch.
+
+We are trying to keep backwards compatibility breaks in PHPUnit to an absolute minimum. Please take this into account when proposing changes.
+
+Due to time constraints, we are not always able to respond as quickly as we would like. Please do not take delays personal and feel free to remind us if you feel that we forgot to respond.
+
+## Coding Guidelines
+
+This project comes with a configuration file for [php-cs-fixer](https://github.com/FriendsOfPHP/PHP-CS-Fixer) (`.php_cs`) that you can use to (re)format your sourcecode for compliance with this project's coding guidelines:
+
+```bash
+$ wget http://get.sensiolabs.org/php-cs-fixer.phar
+
+$ php php-cs-fixer.phar fix
+```
+
+## Using PHPUnit from a Git checkout
+
+The following commands can be used to perform the initial checkout of PHPUnit:
+
+```bash
+$ git clone git://github.com/sebastianbergmann/phpunit.git
+
+$ cd phpunit
+```
+
+Retrieve PHPUnit's dependencies using [Composer](https://getcomposer.org/):
+
+```bash
+$ composer install
+```
+
+The `phpunit` script can be used to invoke the PHPUnit test runner:
+
+```bash
+$ ./phpunit --version
+```
+
+## Reporting issues
+
+Please use the most specific issue tracker to search for existing tickets and to open new tickets:
+
+* [General problems](https://github.com/sebastianbergmann/phpunit/issues)
+* [Code Coverage](https://github.com/sebastianbergmann/php-code-coverage/issues)
+* [Stub and Mock Objects](https://github.com/sebastianbergmann/phpunit-mock-objects/issues)
+* [DbUnit](https://github.com/sebastianbergmann/dbunit/issues)
+* [PHPUnit_Selenium](https://github.com/sebastianbergmann/phpunit-selenium/issues)

+# PHPUnit
+
+PHPUnit is a programmer-oriented testing framework for PHP. It is an instance of the xUnit architecture for unit testing frameworks.
+
+[![Latest Stable Version](https://img.shields.io/packagist/v/phpunit/phpunit.svg?style=flat-square)](https://packagist.org/packages/phpunit/phpunit)
+[![Minimum PHP Version](https://img.shields.io/badge/php-%3E%3D%205.3.3-8892BF.svg?style=flat-square)](https://php.net/)
+[![Build Status](https://img.shields.io/travis/sebastianbergmann/phpunit/4.8.svg?style=flat-square)](https://phpunit.de/build-status.html)
+
+## Installation
+
+We distribute a [PHP Archive (PHAR)](https://php.net/phar) that has all required (as well as some optional) dependencies of PHPUnit bundled in a single file:
+
+```bash
+$ wget https://phar.phpunit.de/phpunit.phar
+
+$ chmod +x phpunit.phar
+
+$ mv phpunit.phar /usr/local/bin/phpunit
+```
+
+You can also immediately use the PHAR after you have downloaded it, of course:
+
+```bash
+$ wget https://phar.phpunit.de/phpunit.phar
+
+$ php phpunit.phar
+```
+
+Alternatively, you may use [Composer](https://getcomposer.org/) to download and install PHPUnit as well as its dependencies. Please refer to the [documentation](https://phpunit.de/documentation.html) for details on how to do this.

+/**
+ * A TestCase defines the fixture to run multiple tests.
+ *
+ * To define a TestCase
+ *
+ *   1) Implement a subclass of PHPUnit_Framework_TestCase.
+ *   2) Define instance variables that store the state of the fixture.
+ *   3) Initialize the fixture state by overriding setUp().
+ *   4) Clean-up after a test by overriding tearDown().
+ *
+ * Each test runs in its own fixture so there can be no side effects
+ * among test runs.
+ *
+ * Here is an example:
+ *
+ * <code>
+ * <?php
+ * class MathTest extends PHPUnit_Framework_TestCase
+ * {
+ *     public $value1;
+ *     public $value2;
+ *
+ *     protected function setUp()
+ *     {
+ *         $this->value1 = 2;
+ *         $this->value2 = 3;
+ *     }
+ * }
+ * ?>
+ * </code>
+ *
+ * For each test implement a method which interacts with the fixture.
+ * Verify the expected results with assertions specified by calling
+ * assert with a boolean.
+ *
+ * <code>
+ * <?php
+ * public function testPass()
+ * {
+ *     $this->assertTrue($this->value1 + $this->value2 == 5);
+ * }
+ * ?>

+# Changelog
+
+All notable changes to this project will be documented in this file, in reverse chronological order by release.
+
+## 1.0.1 - 2016-08-06
+
+### Added
+
+- Nothing.
+
+### Deprecated
+
+- Nothing.
+
+### Removed
+
+- Nothing.
+
+### Fixed
+
+- Updated all `@return self` annotation references in interfaces to use
+  `@return static`, which more closelly follows the semantics of the
+  specification.
+- Updated the `MessageInterface::getHeaders()` return annotation to use the
+  value `string[][]`, indicating the format is a nested array of strings.
+- Updated the `@link` annotation for `RequestInterface::withRequestTarget()`
+  to point to the correct section of RFC 7230.
+- Updated the `ServerRequestInterface::withUploadedFiles()` parameter annotation
+  to add the parameter name (`$uploadedFiles`).
+- Updated a `@throws` annotation for the `UploadedFileInterface::moveTo()`
+  method to correctly reference the method parameter (it was referencing an
+  incorrect parameter name previously).
+
+## 1.0.0 - 2016-05-18
+
+Initial stable release; reflects accepted PSR-7 specification.

+PSR Http Message
+================
+
+This repository holds all interfaces/classes/traits related to
+[PSR-7](http://www.php-fig.org/psr/psr-7/).
+
+Note that this is not a HTTP message implementation of its own. It is merely an
+interface that describes a HTTP message. See the specification for more details.
+
+Usage
+-----
+
+We'll certainly need some stuff in here.

+/**
+ * Representation of an incoming, server-side HTTP request.
+ *
+ * Per the HTTP specification, this interface includes properties for
+ * each of the following:
+ *
+ * - Protocol version
+ * - HTTP method
+ * - URI
+ * - Headers
+ * - Message body
+ *
+ * Additionally, it encapsulates all data as it has arrived to the
+ * application from the CGI and/or PHP environment, including:
+ *
+ * - The values represented in $_SERVER.
+ * - Any cookies provided (generally via $_COOKIE)
+ * - Query string arguments (generally via $_GET, or as parsed via parse_str())
+ * - Upload files, if any (as represented by $_FILES)
+ * - Deserialized body parameters (generally from $_POST)
+ *
+ * $_SERVER values MUST be treated as immutable, as they represent application
+ * state at the time of request; as such, no methods are provided to allow
+ * modification of those values. The other values provide such methods, as they
+ * can be restored from $_SERVER or the request body, and may need treatment
+ * during the application (e.g., body parameters may be deserialized based on
+ * content type).
+ *
+ * Additionally, this interface recognizes the utility of introspecting a
+ * request to derive and match additional parameters (e.g., via URI path
+ * matching, decrypting cookie values, deserializing non-form-encoded body
+ * content, matching authorization headers to users, etc). These parameters
+ * are stored in an "attributes" property.
+ *
+ * Requests are considered immutable; all methods that might change state MUST
+ * be implemented such that they retain the internal state of the current
+ * message and return an instance that contains the changed state.

+PSR Log
+=======
+
+This repository holds all interfaces/classes/traits related to
+[PSR-3](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-3-logger-interface.md).
+
+Note that this is not a logger of its own. It is merely an interface that
+describes a logger. See the specification for more details.
+
+Usage
+-----
+
+If you need a logger, you can use the interface like this:
+
+```php
+<?php
+
+use Psr\Log\LoggerInterface;
+
+class Foo
+{
+    private $logger;
+
+    public function __construct(LoggerInterface $logger = null)
+    {
+        $this->logger = $logger;
+    }
+
+    public function doSomething()
+    {
+        if ($this->logger) {
+            $this->logger->info('Doing work');
+        }
+
+        // do something useful
+    }
+}
+```
+
+You can then pick one of the implementations of the interface to get a logger.
+
+If you want to implement the interface, you can require this package and
+implement `Psr\Log\LoggerInterface` in your code. Please read the
+[specification text](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-3-logger-interface.md)
+for details.

+
+# Comparator
+
+This component provides the functionality to compare PHP values for equality.
+
+## Installation
+
+You can add this library as a local, per-project dependency to your project using [Composer](https://getcomposer.org/):
+
+    composer require sebastian/comparator
+
+If you only need this library during development, for instance to run your project's test suite, then you should add it as a development-time dependency:
+
+    composer require --dev sebastian/comparator
+
+## Usage
+
+```php
+<?php
+use SebastianBergmann\Comparator\Factory;
+use SebastianBergmann\Comparator\ComparisonFailure;
+
+$date1 = new DateTime('2013-03-29 04:13:35', new DateTimeZone('America/New_York'));
+$date2 = new DateTime('2013-03-29 03:13:35', new DateTimeZone('America/Chicago'));
+
+$factory = new Factory;
+$comparator = $factory->getComparatorFor($date1, $date2);
+
+try {
+    $comparator->assertEquals($date1, $date2);
+    print "Dates match";
+}
+
+catch (ComparisonFailure $failure) {
+    print "Dates don't match";
+}
+```

+# sebastian/diff
+
+Diff implementation for PHP, factored out of PHPUnit into a stand-alone component.
+
+## Installation
+
+You can add this library as a local, per-project dependency to your project using [Composer](https://getcomposer.org/):
+
+    composer require sebastian/diff
+
+If you only need this library during development, for instance to run your project's test suite, then you should add it as a development-time dependency:
+
+    composer require --dev sebastian/diff
+
+### Usage
+
+The `Differ` class can be used to generate a textual representation of the difference between two strings:
+
+```php
+use SebastianBergmann\Diff\Differ;
+
+$differ = new Differ;
+print $differ->diff('foo', 'bar');
+```
+
+The code above yields the output below:
+
+    --- Original
+    +++ New
+    @@ @@
+    -foo
+    +bar
+
+The `Parser` class can be used to parse a unified diff into an object graph:
+
+```php
+use SebastianBergmann\Diff\Parser;
+use SebastianBergmann\Git;
+
+$git = new Git('/usr/local/src/money');
+
+$diff = $git->getDiff(
+  '948a1a07768d8edd10dcefa8315c1cbeffb31833',
+  'c07a373d2399f3e686234c4f7f088d635eb9641b'
+);
+
+$parser = new Parser;
+
+print_r($parser->parse($diff));
+```
+
+The code above yields the output below:

+# Environment
+
+This component provides functionality that helps writing PHP code that has runtime-specific (PHP / HHVM) execution paths.
+
+[![Latest Stable Version](https://poser.pugx.org/sebastian/environment/v/stable.png)](https://packagist.org/packages/sebastian/environment)
+[![Build Status](https://travis-ci.org/sebastianbergmann/environment.png?branch=master)](https://travis-ci.org/sebastianbergmann/environment)
+
+## Installation
+
+To add Environment as a local, per-project dependency to your project, simply add a dependency on `sebastian/environment` to your project's `composer.json` file. Here is a minimal example of a `composer.json` file that just defines a dependency on Environment 1.0:
+
+    {
+        "require": {
+            "sebastian/environment": "1.0.*"
+        }
+    }
+
+## Usage
+
+```php
+<?php
+use SebastianBergmann\Environment\Runtime;
+
+$runtime = new Runtime;
+
+var_dump($runtime->getNameWithVersion());
+var_dump($runtime->getName());
+var_dump($runtime->getVersion());
+var_dump($runtime->getBinary());
+var_dump($runtime->isHHVM());
+var_dump($runtime->isPHP());
+var_dump($runtime->hasXdebug());
+var_dump($runtime->canCollectCodeCoverage());
+```

+Exporter
+========
+
+[![Build Status](https://secure.travis-ci.org/sebastianbergmann/exporter.png?branch=master)](https://travis-ci.org/sebastianbergmann/exporter)
+
+This component provides the functionality to export PHP variables for visualization.
+
+## Usage
+
+Exporting:
+
+```php
+<?php
+use SebastianBergmann\Exporter\Exporter;
+
+$exporter = new Exporter;
+
+/*
+Exception Object &0000000078de0f0d000000002003a261 (
+    'message' => ''
+    'string' => ''
+    'code' => 0
+    'file' => '/home/sebastianbergmann/test.php'
+    'line' => 34
+    'trace' => Array &0 ()
+    'previous' => null
+)
+*/
+
+print $exporter->export(new Exception);
+```
+
+## Data Types
+
+Exporting simple types:
+
+```php
+<?php
+use SebastianBergmann\Exporter\Exporter;
+
+$exporter = new Exporter;
+
+// 46
+print $exporter->export(46);
+
+// 4.0
+print $exporter->export(4.0);
+
+// 'hello, world!'
+print $exporter->export('hello, world!');
+
+// false
+print $exporter->export(false);
+
+// NAN
+print $exporter->export(acos(8));
+
+// -INF
+print $exporter->export(log(0));
+
+// null
+print $exporter->export(null);
+
+// resource(13) of type (stream)
+print $exporter->export(fopen('php://stderr', 'w'));
+
+// Binary String: 0x000102030405
+print $exporter->export(chr(0) . chr(1) . chr(2) . chr(3) . chr(4) . chr(5));
+```
+
+Exporting complex types:
+
+```php
+<?php
+use SebastianBergmann\Exporter\Exporter;
+
+$exporter = new Exporter;
+
+/*
+Array &0 (
+    0 => Array &1 (
+        0 => 1
+        1 => 2
+        2 => 3
+    )
+    1 => Array &2 (
+        0 => ''
+        1 => 0
+        2 => false
+    )
+)
+*/
+
+print $exporter->export(array(array(1,2,3), array("",0,FALSE)));
+
+/*
+Array &0 (
+    'self' => Array &1 (
+        'self' => Array &1
+    )
+)
+*/
+
+$array = array();
+$array['self'] = &$array;
+print $exporter->export($array);
+
+/*
+stdClass Object &0000000003a66dcc0000000025e723e2 (
+    'self' => stdClass Object &0000000003a66dcc0000000025e723e2
+)
+*/
+
+$obj = new stdClass();
+$obj->self = $obj;
+print $exporter->export($obj);
+```
+
+Compact exports:
+
+```php
+<?php
+use SebastianBergmann\Exporter\Exporter;
+
+$exporter = new Exporter;
+
+// Array ()
+print $exporter->shortenedExport(array());
+
+// Array (...)
+print $exporter->shortenedExport(array(1,2,3,4,5));
+
+// stdClass Object ()
+print $exporter->shortenedExport(new stdClass);
+
+// Exception Object (...)
+print $exporter->shortenedExport(new Exception);
+
+// this\nis\na\nsuper\nlong\nstring\nt...\nspace
+print $exporter->shortenedExport(
+<<<LONG_STRING
+this
+is
+a
+super
+long
+string
+that
+wraps
+a
+lot
+and
+eats
+up
+a
+lot
+of
+space
+LONG_STRING
+);
+```
+
+## Installation
+
+To add Exporter as a local, per-project dependency to your project, simply add a dependency on `sebastian/exporter` to your project's `composer.json` file. Here is a minimal example of a `composer.json` file that just defines a dependency on Exporter 1.0:
+
+    {
+        "require": {
+            "sebastian/exporter": "1.0.*"
+        }
+    }

+# GlobalState
+
+Snapshotting of global state, factored out of PHPUnit into a stand-alone component.
+
+[![Build Status](https://travis-ci.org/sebastianbergmann/global-state.svg?branch=master)](https://travis-ci.org/sebastianbergmann/global-state)
+
+## Installation
+
+To add this package as a local, per-project dependency to your project, simply add a dependency on `sebastian/global-state` to your project's `composer.json` file. Here is a minimal example of a `composer.json` file that just defines a dependency on GlobalState:
+
+    {
+        "require": {
+            "sebastian/global-state": "1.0.*"
+        }
+    }

+# Version
+
+**Version** is a library that helps with managing the version number of Git-hosted PHP projects.
+
+## Installation
+
+Simply add a dependency on `sebastian/version` to your project's `composer.json` file if you use [Composer](http://getcomposer.org/) to manage the dependencies of your project.
+
+## Usage
+
+The constructor of the `SebastianBergmann\Version` class expects two parameters:
+
+* `$release` is the version number of the latest release (`X.Y.Z`, for instance) or the name of the release series (`X.Y`) when no release has been made from that branch / for that release series yet.
+* `$path` is the path to the directory (or a subdirectory thereof) where the sourcecode of the project can be found. Simply passing `__DIR__` here usually suffices.
+
+Apart from the constructor, the `SebastianBergmann\Version` class has a single public method: `getVersion()`.
+
+Here is a contrived example that shows the basic usage:
+
+    <?php
+    $version = new SebastianBergmann\Version(
+      '3.7.10', '/usr/local/src/phpunit'
+    );
+
+    var_dump($version->getVersion());
+    ?>
+
+    string(18) "3.7.10-17-g00f3408"
+
+When a new release is prepared, the string that is passed to the constructor as the first argument needs to be updated.
+
+### How SebastianBergmann\Version::getVersion() works
+
+* If `$path` is not (part of) a Git repository and `$release` is in `X.Y.Z` format then `$release` is returned as-is.
+* If `$path` is not (part of) a Git repository and `$release` is in `X.Y` format then `$release` is returned suffixed with `-dev`.
+* If `$path` is (part of) a Git repository and `$release` is in `X.Y.Z` format then the output of `git describe --tags` is returned as-is.
+* If `$path` is (part of) a Git repository and `$release` is in `X.Y` format then a string is returned that begins with `X.Y` and ends with information from `git describe --tags`.

+Contributing
+-------------
+
+Before you contribute code to PHP\_CodeSniffer, please make sure it conforms to the PHPCS coding standard and that the PHP\_CodeSniffer unit tests still pass. The easiest way to contribute is to work on a checkout of the repository, or your own fork, rather than an installed PEAR version. If you do this, you can run the following commands to check if everything is ready to submit:
+
+    cd PHP_CodeSniffer
+    php scripts/phpcs
+
+Which should give you no output, indicating that there are no coding standard errors. And then:
+
+    phpunit
+
+Which should give you no failures or errors. You can ignore any skipped tests as these are for external tools.

+/**
+ * PHP_CodeSniffer tokenizes PHP code and detects violations of a
+ * defined set of coding standards.
+ *
+ * Standards are specified by classes that implement the PHP_CodeSniffer_Sniff
+ * interface. A sniff registers what token types it wishes to listen for, then
+ * PHP_CodeSniffer encounters that token, the sniff is invoked and passed
+ * information about where the token was found in the stack, and the token stack
+ * itself.
+ *
+ * Sniff files and their containing class must be prefixed with Sniff, and
+ * have an extension of .php.
+ *
+ * Multiple PHP_CodeSniffer operations can be performed by re-calling the
+ * process function with different parameters.

+
+/**
+ * A PHP_CodeSniffer_File object represents a PHP source file and the tokens
+ * associated with it.
+ *
+ * It provides a means for traversing the token stack, along with
+ * other token related operations. If a PHP_CodeSniffer_Sniff finds and error or
+ *  warning within a PHP_CodeSniffer_File, you can raise an error using the
+ *  addError() or addWarning() methods.
+ *
+ * <b>Token Information</b>
+ *
+ * Each token within the stack contains information about itself:
+ *
+ * <code>
+ *   array(
+ *    'code'       => 301,       // the token type code (see token_get_all())
+ *    'content'    => 'if',      // the token content
+ *    'type'       => 'T_IF',    // the token name
+ *    'line'       => 56,        // the line number when the token is located
+ *    'column'     => 12,        // the column in the line where this token
+ *                               // starts (starts from 1)
+ *    'level'      => 2          // the depth a token is within the scopes open
+ *    'conditions' => array(     // a list of scope condition token
+ *                               // positions => codes that
+ *                     2 => 50,  // opened the scopes that this token exists
+ *                     9 => 353, // in (see conditional tokens section below)
+ *                    ),
+ *   );
+ * </code>
+ *
+ * <b>Conditional Tokens</b>
+ *
+ * In addition to the standard token fields, conditions contain information to
+ * determine where their scope begins and ends:
+ *
+ * <code>
+ *   array(
+ *    'scope_condition' => 38, // the token position of the condition
+ *    'scope_opener'    => 41, // the token position that started the scope
+ *    'scope_closer'    => 70, // the token position that ended the scope
+ *   );
+ * </code>
+ *
+ * The condition, the scope opener and the scope closer each contain this
+ * information.
+ *
+ * <b>Parenthesis Tokens</b>
+ *
+ * Each parenthesis token (T_OPEN_PARENTHESIS and T_CLOSE_PARENTHESIS) has a
+ * reference to their opening and closing parenthesis, one being itself, the
+ * other being its opposite.
+ *
+ * <code>
+ *   array(
+ *    'parenthesis_opener' => 34,
+ *    'parenthesis_closer' => 40,
+ *   );
+ * </code>
+ *
+ * Some tokens can "own" a set of parenthesis. For example a T_FUNCTION token
+ * has parenthesis around its argument list. These tokens also have the
+ * parenthesis_opener and and parenthesis_closer indices. Not all parenthesis
+ * have owners, for example parenthesis used for arithmetic operations and
+ * function calls. The parenthesis tokens that have an owner have the following
+ * auxiliary array indices.
+ *
+ * <code>
+ *   array(
+ *    'parenthesis_opener' => 34,
+ *    'parenthesis_closer' => 40,
+ *    'parenthesis_owner'  => 33,
+ *   );
+ * </code>
+ *
+ * Each token within a set of parenthesis also has an array index
+ * 'nested_parenthesis' which is an array of the
+ * left parenthesis => right parenthesis token positions.
+ *
+ * <code>
+ *   'nested_parenthesis' => array(
+ *                             12 => 15
+ *                             11 => 14
+ *                            );
+ * </code>
+ *
+ * <b>Extended Tokens</b>
+ *
+ * PHP_CodeSniffer extends and augments some of the tokens created by
+ * <i>token_get_all()</i>. A full list of these tokens can be seen in the
+ * <i>Tokens.php</i> file.

+About
+-----
+
+PHP\_CodeSniffer is a set of two PHP scripts; the main `phpcs` script that tokenizes PHP, JavaScript and CSS files to detect violations of a defined coding standard, and a second `phpcbf` script to automatically correct coding standard violations. PHP\_CodeSniffer is an essential development tool that ensures your code remains clean and consistent.
+
+[![Build Status](https://travis-ci.org/squizlabs/PHP_CodeSniffer.svg?branch=phpcs-fixer)](https://travis-ci.org/squizlabs/PHP_CodeSniffer) [![Code consistency](http://squizlabs.github.io/PHP_CodeSniffer/analysis/squizlabs/PHP_CodeSniffer/grade.svg)](http://squizlabs.github.io/PHP_CodeSniffer/analysis/squizlabs/PHP_CodeSniffer)
+
+[![Join the chat at https://gitter.im/squizlabs/PHP_CodeSniffer](https://badges.gitter.im/Join%20Chat.svg)](https://gitter.im/squizlabs/PHP_CodeSniffer?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge)
+
+Requirements
+------------
+
+PHP\_CodeSniffer requires PHP version 5.1.2 or greater, although individual sniffs may have additional requirements such as external applications and scripts. See the [Configuration Options manual page](https://github.com/squizlabs/PHP_CodeSniffer/wiki/Configuration-Options) for a list of these requirements.
+
+The SVN pre-commit hook requires PHP version 5.2.4 or greater due to its use of the vertical whitespace character.
+
+Installation
+------------
+
+The easiest way to get started with PHP\_CodeSniffer is to download the [Phar](http://php.net/manual/en/intro.phar.php) files for each of the commands:
+
+    curl -OL https://squizlabs.github.io/PHP_CodeSniffer/phpcs.phar
+    php phpcs.phar -h
+
+    curl -OL https://squizlabs.github.io/PHP_CodeSniffer/phpcbf.phar
+    php phpcbf.phar -h
+
+If you use PEAR, you can install PHP\_CodeSniffer using the PEAR installer. This will make the `phpcs` and `phpcbf` commands immediately available for use. To install PHP\_CodeSniffer using the PEAR installer, first ensure you have [installed PEAR](http://pear.php.net/manual/en/installation.getting.php) and then run the following command:
+
+    pear install PHP_CodeSniffer
+
+If you prefer using [Composer](http://getcomposer.org/) you can easily install PHP_CodeSniffer system-wide with the following command:
+
+    composer global require "squizlabs/php_codesniffer=*"
+
+Make sure you have the composer bin dir in your PATH. The default value is `~/.composer/vendor/bin/`, but you can check the value that you need to use by running `composer global config bin-dir --absolute`.
+
+Or alternatively, include a dependency for `squizlabs/php_codesniffer` in your `composer.json` file. For example:
+
+```json
+{
+    "require-dev": {
+        "squizlabs/php_codesniffer": "2.*"
+    }
+}
+```
+
+You will then be able to run PHP_CodeSniffer from the vendor bin directory:
+
+    ./vendor/bin/phpcs -h
+    ./vendor/bin/phpcbf -h
+
+You can also download the PHP\_CodeSniffer source and run the `phpcs` and `phpcbf` commands directly from the Git clone:
+
+    git clone https://github.com/squizlabs/PHP_CodeSniffer.git
+    cd PHP_CodeSniffer
+    php scripts/phpcs -h
+    php scripts/phpcbf -h
+
+Documentation
+-------------
+
+The documentation for PHP\_CodeSniffer is available on the [Github wiki](https://github.com/squizlabs/PHP_CodeSniffer/wiki).
+
+Information about upcoming features and releases is available on the [Squiz Labs blog](http://www.squizlabs.com/php-codesniffer).
+
+Issues
+------
+
+Bug reports and feature requests can be submitted on the [Github Issue Tracker](https://github.com/squizlabs/PHP_CodeSniffer/issues) or the [PEAR bug tracker](http://pear.php.net/package/PHP_CodeSniffer/bugs).

+CHANGELOG
+=========
+
+3.4.0
+-----
+
+ * added `SHELL_VERBOSITY` env var to control verbosity
+ * added `CommandLoaderInterface`, `FactoryCommandLoader` and PSR-11
+   `ContainerCommandLoader` for commands lazy-loading
+ * added a case-insensitive command name matching fallback
+ * added static `Command::$defaultName/getDefaultName()`, allowing for
+   commands to be registered at compile time in the application command loader.
+   Setting the `$defaultName` property avoids the need for filling the `command`
+   attribute on the `console.command` tag when using `AddConsoleCommandPass`.
+
+3.3.0
+-----
+

+/**
+ * A generic ErrorHandler for the PHP engine.
+ *
+ * Provides five bit fields that control how errors are handled:
+ * - thrownErrors: errors thrown as \ErrorException
+ * - loggedErrors: logged errors, when not @-silenced
+ * - scopedErrors: errors thrown or logged with their local context
+ * - tracedErrors: errors logged with their stack trace
+ * - screamedErrors: never @-silenced errors
+ *
+ * Each error level can be logged by a dedicated PSR-3 logger object.
+ * Screaming only applies to logging.
+ * Throwing takes precedence over logging.
+ * Uncaught exceptions are logged as E_ERROR.
+ * E_DEPRECATED and E_USER_DEPRECATED levels never throw.
+ * E_RECOVERABLE_ERROR and E_USER_ERROR levels always throw.
+ * Non catchable errors that can be detected at shutdown time are logged when the scream bit field allows so.
+ * As errors have a performance cost, repeated errors are all logged, so that the developer
+ * can see them and weight them as more important to fix than others of the same level.

+-----
+
+  * Implementing `TraceableEventDispatcherInterface` without the `reset()` method has been deprecated.
+
+3.3.0
+-----
+
+  * The ContainerAwareEventDispatcher class has been deprecated. Use EventDispatcher with closure factories instead.
+
+3.0.0

+
+  * The method `getListenerPriority($eventName, $listener)` has been added to the
+    `EventDispatcherInterface`.
+  * The methods `Event::setDispatcher()`, `Event::getDispatcher()`, `Event::setName()`
+    and `Event::getName()` have been removed.
+    The event dispatcher and the event name are passed to the listener call.
+
+2.5.0
+-----
+
+ * added Debug\TraceableEventDispatcher (originally in HttpKernel)
+ * changed Debug\TraceableEventDispatcherInterface to extend EventDispatcherInterface
+ * added RegisterListenersPass (originally in HttpKernel)

+-----
+
+ * added TraceableEventDispatcherInterface
+ * added ContainerAwareEventDispatcher
+ * added a reference to the EventDispatcher on the Event
+ * added a reference to the Event name on the event

+ * added the possibility for subscribers to subscribe several times for the
+   same event
+ * added ImmutableEventDispatcher

+CHANGELOG
+=========
+
+3.4.0
+-----
+
+ * added support for parsing YAML files using the `Yaml::parseFile()` or `Parser::parseFile()` method
+
+ * the `Dumper`, `Parser`, and `Yaml` classes are marked as final
+
+ * Deprecated the `!php/object:` tag which will be replaced by the
+   `!php/object` tag (without the colon) in 4.0.
+
+ * Deprecated the `!php/const:` tag which will be replaced by the
+   `!php/const` tag (without the colon) in 4.0.
+
+ * Support for the `!str` tag is deprecated, use the `!!str` tag instead.
+
+ * Deprecated using the non-specific tag `!` as its behavior will change in 4.0.
+   It will force non-evaluating your values in 4.0. Use plain integers or `!!float` instead.
+
+3.3.0
+-----
+
+ * Starting an unquoted string with a question mark followed by a space is
+   deprecated and will throw a `ParseException` in Symfony 4.0.
+
+ * Deprecated support for implicitly parsing non-string mapping keys as strings.
+   Mapping keys that are no strings will lead to a `ParseException` in Symfony
+   4.0. Use quotes to opt-in for keys to be parsed as strings.
+
+   Before:
+
+   ```php
+   $yaml = <<<YAML
+   null: null key
+   true: boolean true
+   2.0: float key
+   YAML;
+
+   Yaml::parse($yaml);
+   ```
+
+   After:
+
+   ```php
+
+   $yaml = <<<YAML
+   "null": null key
+   "true": boolean true
+   "2.0": float key
+   YAML;
+
+   Yaml::parse($yaml);
+   ```
+
+ * Omitted mapping values will be parsed as `null`.
+
+ * Omitting the key of a mapping is deprecated and will throw a `ParseException` in Symfony 4.0.
+
+ * Added support for dumping empty PHP arrays as YAML sequences:
+
+   ```php
+   Yaml::dump([], 0, 0, Yaml::DUMP_EMPTY_ARRAY_AS_SEQUENCE);
+   ```
+
+3.2.0
+-----
+
+ * Mappings with a colon (`:`) that is not followed by a whitespace are deprecated
+   when the mapping key is not quoted and will lead to a `ParseException` in
+   Symfony 4.0 (e.g. `foo:bar` must be `foo: bar`).
+
+ * Added support for parsing PHP constants:
+
+   ```php
+   Yaml::parse('!php/const:PHP_INT_MAX', Yaml::PARSE_CONSTANT);
+   ```
+
+ * Support for silently ignoring duplicate mapping keys in YAML has been
+   deprecated and will lead to a `ParseException` in Symfony 4.0.
+
+3.1.0
+-----
+
+ * Added support to dump `stdClass` and `ArrayAccess` objects as YAML mappings
+   through the `Yaml::DUMP_OBJECT_AS_MAP` flag.
+
+ * Strings that are not UTF-8 encoded will be dumped as base64 encoded binary
+   data.
+
+ * Added support for dumping multi line strings as literal blocks.
+
+ * Added support for parsing base64 encoded binary data when they are tagged
+   with the `!!binary` tag.
+
+ * Added support for parsing timestamps as `\DateTime` objects:
+
+   ```php
+   Yaml::parse('2001-12-15 21:59:43.10 -5', Yaml::PARSE_DATETIME);
+   ```
+
+ * `\DateTime` and `\DateTimeImmutable` objects are dumped as YAML timestamps.
+
+ * Deprecated usage of `%` at the beginning of an unquoted string.
+
+ * Added support for customizing the YAML parser behavior through an optional bit field:
+
+   ```php
+   Yaml::parse('{ "foo": "bar", "fiz": "cat" }', Yaml::PARSE_EXCEPTION_ON_INVALID_TYPE | Yaml::PARSE_OBJECT | Yaml::PARSE_OBJECT_FOR_MAP);
+   ```
+
+ * Added support for customizing the dumped YAML string through an optional bit field:
+
+   ```php
+   Yaml::dump(array('foo' => new A(), 'bar' => 1), 0, 0, Yaml::DUMP_EXCEPTION_ON_INVALID_TYPE | Yaml::DUMP_OBJECT);
+   ```
+
+3.0.0
+-----
+
+ * Yaml::parse() now throws an exception when a blackslash is not escaped
+   in double-quoted strings
+
+2.8.0
+-----
+
+ * Deprecated usage of a colon in an unquoted mapping value
+ * Deprecated usage of @, \`, | and > at the beginning of an unquoted string
+ * When surrounding strings with double-quotes, you must now escape `\` characters. Not
+   escaping those characters (when surrounded by double-quotes) is deprecated.
+
+   Before:
+
+   ```yml
+   class: "Foo\Var"
+   ```
+
+   After:
+
+   ```yml
+   class: "Foo\\Var"
+   ```
+
+2.1.0
+-----
+
+ * Yaml::parse() does not evaluate loaded files as PHP files by default
+   anymore (call Yaml::enablePhpParsing() to get back the old behavior)

+Webmozart Assert

+[![Build status](https://ci.appveyor.com/api/projects/status/lyg83bcsisrr94se/branch/master?svg=true)](https://ci.appveyor.com/project/webmozart/assert/branch/master)
+[![Latest Stable Version](https://poser.pugx.org/webmozart/assert/v/stable.svg)](https://packagist.org/packages/webmozart/assert)
+[![Total Downloads](https://poser.pugx.org/webmozart/assert/downloads.svg)](https://packagist.org/packages/webmozart/assert)
+[![Dependency Status](https://www.versioneye.com/php/webmozart:assert/1.2.0/badge.svg)](https://www.versioneye.com/php/webmozart:assert/1.2.0)
+
+Latest release: [1.2.0](https://packagist.org/packages/webmozart/assert#1.2.0)
+
+PHP >= 5.3.9
+
+This library contains efficient assertions to test the input and output of
+your methods. With these assertions, you can greatly reduce the amount of coding
+needed to write a safe implementation.
+
+All assertions in the [`Assert`] class throw an `\InvalidArgumentException` if 
+they fail.
+
+FAQ
+---
+
+**What's the difference to [beberlei/assert]?**
+
+This library is heavily inspired by Benjamin Eberlei's wonderful [assert package],
+but fixes a usability issue with error messages that can't be fixed there without
+breaking backwards compatibility.
+
+This package features usable error messages by default. However, you can also 
+easily write custom error messages:
+
+```
+Assert::string($path, 'The path is expected to be a string. Got: %s');
+```
+
+In [beberlei/assert], the ordering of the `%s` placeholders is different for 
+every assertion. This package, on the contrary, provides consistent placeholder 
+ordering for all assertions:
+
+* `%s`: The tested value as string, e.g. `"/foo/bar"`.
+* `%2$s`, `%3$s`, ...: Additional assertion-specific values, e.g. the
+  minimum/maximum length, allowed values, etc.
+  
+Check the source code of the assertions to find out details about the additional
+available placeholders.
+
+Installation
+------------
+
+Use [Composer] to install the package:
+
+```
+$ composer require webmozart/assert
+```
+
+Example
+-------
+
+```php
+use Webmozart\Assert\Assert;
+
+class Employee
+{
+    public function __construct($id)
+    {
+        Assert::integer($id, 'The employee ID must be an integer. Got: %s');
+        Assert::greaterThan($id, 0, 'The employee ID must be a positive integer. Got: %s');
+    }
+}
+```
+
+If you create an employee with an invalid ID, an exception is thrown:
+
+```php
+new Employee('foobar');
+// => InvalidArgumentException: 
+//    The employee ID must be an integer. Got: string
+
+new Employee(-10);
+// => InvalidArgumentException: 
+//    The employee ID must be a positive integer. Got: -10
+```
+
