+PHP Markdown & Extra
+====================
+
+An updated and stripped version of the original [PHP Markdown](http://michelf.com/projects/php-markdown/)
+by [Michel Fortin](http://michelf.com/). Works quite well with PSR-0
+autoloaders and is [Composer](http://packagist.org/) friendly.
+
+
+Changes from the official PHP Markdown & Extra
+----------------------------------------------
+
+The initial pass at updating PHP Markdown & Extra left the core of
+the code more or less intact but the changes to the organization
+and naming were quite substantial. This effectively makes this package
+a hard fork from Markdown 1.0.1n and MarkdownExtra 1.2.4.
+
+Updated in the following ways:
+
+ * Moved parser classes into their own files
+ * Using PHP 5.3 namespaces
+ * Following [PSR-0](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-0.md) standards
+ * Replaced `@define` configuration variables with class `const` variables
+ * Integrated with [Travis CI](http://travis-ci.org/)
+ * Made [Composer](http://packagist.org/) friendly
+
+Stripped in the following ways:
+
+ * No more embedded plugin code (WordPress, bBlog, etc.)
+ * No more top level function calls (`Markdown()`, etc.)
+
+
+Requirements
+------------
+
+ * PHP 5.3+
+
+
+Usage
+-----
+
+Simple usage for the standard Markdown ([details](http://michelf.com/projects/php-markdown/)) parser:
+
+    <?php
+    use dflydev\markdown\Markdown;
+
+    $markdownParser = new MarkdownParser();
+
+    // Will return <h1>Hello World</h1>
+    $markdownParser->transformMarkdown("#Hello World");
+
+Simple usage for the Markdown Extra ([details](http://michelf.com/projects/php-markdown/extra/)) parser:
+
+    <?php
+    use dflydev\markdown\MarkdownExtra;
+
+    $markdownParser = new MarkdownExtraParser();
+
+    // Will return <h1>Hello World</h1>
+    $markdownParser->transformMarkdown("#Hello World");

+
+
+Not Invented Here
+-----------------
+
+The original [PHP Markdown](http://michelf.com/projects/php-markdown/) was
+quite excellent but was not as easy to use as it could be in more modern PHP
+applications. Having started to use [Composer](http://packagist.org/) for a
+few newer applications that needed to transform Markdown, I decided to strip
+and update the original PHP Markdown so that it could be more easily managed
+by the likes of Composer.
+
+All of the initial work done for this library (which I can only assume
+was quite substantial after having looked at the code) was done by
+[Michel Fortin](http://michelf.com/) during the original port from Perl to
+PHP.
+
+If you do not need to install PHP Markdown by way of Composer or need to
+leverage PSR-0 autoloading, I suggest you continue to use the official and
+likely more stable and well used original version of
+[PHP Markdown](http://michelf.com/projects/php-markdown/)

+
+PHP Markdown Extra
+==================
+
+Description
+-----------
+
+This is a PHP port of the original Markdown formatter written in Perl 
+by John Gruber. This special "Extra" version of PHP Markdown features 
+further enhancements to the syntax for making additional constructs 
+such as tables and definition list.
+
+Markdown is a text-to-HTML filter; it translates an easy-to-read /
+easy-to-write structured text format into HTML. Markdown's text format
+is most similar to that of plain text email, and supports features such
+as headers, *emphasis*, code blocks, blockquotes, and links.
+
+Markdown's syntax is designed not as a generic markup language, but
+specifically to serve as a front-end to (X)HTML. You can use span-level
+HTML tags anywhere in a Markdown document, and you can use block level
+HTML tags (like <div> and <table> as well).
+
+For more information about Markdown's syntax, see:
+
+<http://daringfireball.net/projects/markdown/>
+
+
+Bugs

+
+Please include with your report: (1) the example input; (2) the output you
+expected; (3) the output Markdown actually produced.

 # Doctrine Collections
 
 Collections Abstraction library
-
-## Changelog
-
-### v1.2
-
-* Add a new ``AbstractLazyCollection``
-
-### v1.1
-
-* Deprecated ``Comparison::IS``, because it's only there for SQL semantics.
-  These are fixed in the ORM instead.
-* Add ``Comparison::CONTAINS`` to perform partial string matches:
-
-        $criteria->andWhere($criteria->expr()->contains('property', 'Foo'));

+  Names that can
+  be resolved to MX RRs or address (i.e., A or AAAA) RRs (as discussed
+  in Section 5) are permitted, as are CNAME RRs whose targets can be
+  resolved, in turn, to MX or address RRs.
+
+http://tools.ietf.org/html/rfc5321#section-5.1
+  The lookup first attempts to locate an MX record associated with the
+  name.  If a CNAME record is found, the resulting name is processed as
+  if it were the initial name. ... If an empty list of MXs is returned,
+  the address is treated as if it was associated with an implicit MX
+  RR, with a preference of 0, pointing to that host.
+
+is_email() author's note: We will regard the existence of a CNAME to be
+sufficient evidence of the domain's existence. For performance reasons
+we will not repeat the DNS lookup for the CNAME's target, but we will
+raise a warning because we didn't immediately find an MX record.
+
+Check for TLD addresses
+-----------------------
+TLD addresses are specifically allowed in RFC 5321 but they are
+unusual to say the least. We will allocate a separate
+status to these addresses on the basis that they are more likely
+to be typos than genuine addresses (unless we've already
+established that the domain does have an MX record)
+
+http://tools.ietf.org/html/rfc5321#section-2.3.5
+  In the case
+  of a top-level domain used by itself in an email address, a single
+  string is used without any dots.  This makes the requirement,
+  described in more detail below, that only fully-qualified domain
+  names appear in SMTP transactions on the public Internet,
+  particularly important where top-level domains are involved.
+
+TLD format
+----------
+The format of TLDs has changed a number of times. The standards
+used by IANA have been largely ignored by ICANN, leading to
+confusion over the standards being followed. These are not defined
+anywhere, except as a general component of a DNS host name (a label).
+However, this could potentially lead to 123.123.123.123 being a
+valid DNS name (rather than an IP address) and thereby creating
+an ambiguity. The most authoritative statement on TLD formats that
+the author can find is in a (rejected!) erratum to RFC 1123
+submitted by John Klensin, the author of RFC 5321:
+
+http://www.rfc-editor.org/errata_search.php?rfc=1123&eid=1353
+  However, a valid host name can never have the dotted-decimal
+  form #.#.#.#, since this change does not permit the highest-level
+  component label to start with a digit even if it is not all-numeric.

+PHP_Timer
+=========
+
+Installation
+------------
+
+PHP_Timer should be installed using the [PEAR Installer](http://pear.php.net/). This installer is the backbone of PEAR, which provides a distribution system for PHP packages, and is shipped with every release of PHP since version 4.3.0.
+
+The PEAR channel (`pear.phpunit.de`) that is used to distribute PHP_Timer needs to be registered with the local PEAR environment:
+
+    sb@ubuntu ~ % pear channel-discover pear.phpunit.de
+    Adding Channel "pear.phpunit.de" succeeded
+    Discovery of channel "pear.phpunit.de" succeeded
+
+This has to be done only once. Now the PEAR Installer can be used to install packages from the PHPUnit channel:
+
+    sb@vmware ~ % pear install phpunit/PHP_Timer
+    downloading PHP_Timer-1.0.0.tgz ...
+    Starting to download PHP_Timer-1.0.0.tgz (2,536 bytes)
+    ....done: 2,536 bytes
+    install ok: channel://pear.phpunit.de/PHP_Timer-1.0.0
+
+After the installation you can find the PHP_Timer source files inside your local PEAR directory; the path is usually `/usr/lib/php/PHP`.

-# PHP_Timer
-
-Utility class for timing things, factored out of PHPUnit into a stand-alone component.
-
-## Installation
-
-You can use the [PEAR Installer](http://pear.php.net/manual/en/guide.users.commandline.cli.php) or [Composer](http://getcomposer.org/) to download and install this package as well as its dependencies.
-
-### PEAR Installer
-
-The following two commands (which you may have to run as `root`) are all that is required to install this package using the PEAR Installer:
-
-    pear config-set auto_discover 1
-    pear install pear.phpunit.de/PHP_Timer
-
-### Composer
-
-To add this package as a local, per-project dependency to your project, simply add a dependency on `phpunit/php-timer` to your project's `composer.json` file. Here is a minimal example of a `composer.json` file that just defines a dependency on PHP_Timer:
-
-    {
-        "require": {
-            "phpunit/php-timer": "*"
-        }
-    }
-
-### Usage
-
-#### Basic Timing
-
-```php
-PHP_Timer::start();
-
-$timer->start();
-
-// ...
-
-$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

 ## 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.
+There are two supported ways of installing Version.
+
+You can use the [PEAR Installer](http://pear.php.net/manual/en/guide.users.commandline.cli.php) or [Composer](http://getcomposer.org/) to download and install Version.
+
+### PEAR Installer
+
+The following two commands (which you may have to run as `root`) are all that is required to install Version using the PEAR Installer:
+
+    pear config-set auto_discover 1
+    pear install pear.phpunit.de/Version
+
+### Composer
+
+To add Version as a local, per-project dependency to your project, simply add a dependency on `sebastian/version` to your project's `composer.json` file.

-BrowserKit Component
-====================
-
-BrowserKit simulates the behavior of a web browser.
-
-The component only provide an abstract client and does not provide any
-"default" backend for the HTTP layer.
-
-Resources
----------
-
-For a simple implementation of a browser based on an HTTP layer, have a look
-at [Goutte](https://github.com/fabpot/Goutte).
-
-For an implementation based on HttpKernelInterface, have a look at the
-[Client](https://github.com/symfony/symfony/blob/master/src/Symfony/Component/HttpKernel/Client.php)
-provided by the HttpKernel component.
-
-You can run the unit tests with the following command:
-
-    $ cd path/to/Symfony/Component/BrowserKit/
-    $ composer install
-    $ phpunit

+BrowserKit Component
+====================
+
+BrowserKit simulates the behavior of a web browser.
+
+The component only provide an abstract client and does not provide any
+"default" backend for the HTTP layer.
+
+Resources
+---------
+
+For a simple implementation of a browser based on an HTTP layer, have a look
+at [Goutte](https://github.com/fabpot/Goutte).
+
+For an implementation based on HttpKernelInterface, have a look at the
+[Client](https://github.com/symfony/symfony/blob/master/src/Symfony/Component/HttpKernel/Client.php)
+provided by the HttpKernel component.
+
+You can run the unit tests with the following command:
+
+    phpunit
+
+If you also want to run the unit tests that depend on other Symfony
+Components, install dev dependencies before running PHPUnit:
+
+    php composer.phar install --dev

-/**
- * 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, only once for repeated errors
- * - 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.

-Debug Component
-===============
-
-Debug provides tools to make debugging easier.
-
-Enabling all debug tools is as easy as calling the `enable()` method on the
-main `Debug` class:
-
-```php
-use Symfony\Component\Debug\Debug;
-
-Debug::enable();
-```
-
-You can also use the tools individually:
-
-```php
-use Symfony\Component\Debug\ErrorHandler;
-use Symfony\Component\Debug\ExceptionHandler;
-
-if ('cli' !== php_sapi_name()) {
-    ini_set('display_errors', 0);
-    ExceptionHandler::register();
-} elseif (!ini_get('log_errors') || ini_get('error_log')) {
-    ini_set('display_errors', 1);
-}
-ErrorHandler::register();
-```
-
-Note that the `Debug::enable()` call also registers the debug class loader
-from the Symfony ClassLoader component when available.
-
-This component can optionally take advantage of the features of the HttpKernel
-and HttpFoundation components.
-
-Resources
----------
-
-You can run the unit tests with the following command:
-
-    $ cd path/to/Symfony/Component/Debug/
-    $ composer install
-    $ phpunit

-Symfony Debug Extension
-=======================
-
-This extension publishes several functions to help building powerful debugging tools.
-
-symfony_zval_info()
--------------------
-
-- exposes zval_hash/refcounts, allowing e.g. efficient exploration of arbitrary structures in PHP,
-- does work with references, preventing memory copying.
-
-Its behavior is about the same as:
-
-```php
-<?php
-
-function symfony_zval_info($key, $array, $options = 0)
-{
-
-    // $options is currently not used, but could be in future version.
-
-    if (!array_key_exists($key, $array)) {
-        return null;
-    }
-
-    $info = array(
-        'type' => gettype($array[$key]),
-        'zval_hash' => /* hashed memory address of $array[$key] */,
-        'zval_refcount' => /* internal zval refcount of $array[$key] */,
-        'zval_isref' => /* is_ref status of $array[$key] */,
-    );
-
-    switch ($info['type']) {
-        case 'object':
-            $info += array(
-                'object_class' => get_class($array[$key]),
-                'object_refcount' => /* internal object refcount of $array[$key] */,
-                'object_hash' => spl_object_hash($array[$key]),
-                'object_handle' => /* internal object handle $array[$key] */,
-            );
-            break;
-
-        case 'resource':
-            $info += array(
-                'resource_handle' => (int) $array[$key],
-                'resource_type' => get_resource_type($array[$key]),
-                'resource_refcount' => /* internal resource refcount of $array[$key] */,
-            );
-            break;
-
-        case 'array':
-            $info += array(
-                'array_count' => count($array[$key]),
-            );
-            break;
-
-        case 'string':
-            $info += array(
-                'strlen' => strlen($array[$key]),
-            );
-            break;
-    }
-
-    return $info;
-}
-```
-
-symfony_debug_backtrace()
--------------------------
-
-This function works like debug_backtrace(), except that it can fetch the full backtrace in case of fatal errors:
-
-```php
-function foo() { fatal(); }
-function bar() { foo(); }
-
-function sd() { var_dump(symfony_debug_backtrace()); }
-
-register_shutdown_function('sd');
-
-bar();
-
-/* Will output
-Fatal error: Call to undefined function fatal() in foo.php on line 42
-array(3) {
-  [0]=>
-  array(2) {
-    ["function"]=>
-    string(2) "sd"
-    ["args"]=>
-    array(0) {
-    }
-  }
-  [1]=>
-  array(4) {
-    ["file"]=>
-    string(7) "foo.php"
-    ["line"]=>
-    int(1)
-    ["function"]=>
-    string(3) "foo"
-    ["args"]=>
-    array(0) {
-    }
-  }
-  [2]=>
-  array(4) {
-    ["file"]=>
-    string(102) "foo.php"
-    ["line"]=>
-    int(2)
-    ["function"]=>
-    string(3) "bar"
-    ["args"]=>
-    array(0) {
-    }
-  }
-}
-*/
-```
-
-Usage
------
-
-The extension is compatible with ZTS mode, and should be supported by PHP5.3, 5.4, 5.5 and 5.6.
-To enable the extension from source, run:
-
-```
-    phpize
-    ./configure
-    make
-    sudo make install
-```

+/**
+ * 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, only once for repeated errors
+ * - 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.

+Debug Component
+===============
+
+Debug provides tools to make debugging easier.
+
+Enabling all debug tools is as easy as calling the `enable()` method on the
+main `Debug` class:
+
+```php
+use Symfony\Component\Debug\Debug;
+
+Debug::enable();
+```
+
+You can also use the tools individually:
+
+```php
+use Symfony\Component\Debug\ErrorHandler;
+use Symfony\Component\Debug\ExceptionHandler;
+
+if ('cli' !== php_sapi_name()) {
+    ini_set('display_errors', 0);
+    ExceptionHandler::register();
+} elseif (!ini_get('log_errors') || ini_get('error_log')) {
+    ini_set('display_errors', 1);
+}
+ErrorHandler::register();
+```
+
+Note that the `Debug::enable()` call also registers the debug class loader
+from the Symfony ClassLoader component when available.
+
+This component can optionally take advantage of the features of the HttpKernel
+and HttpFoundation components.
+
+Resources
+---------
+
+You can run the unit tests with the following command:
+
+    $ cd path/to/Symfony/Component/Debug/
+    $ composer.phar install --dev
+    $ phpunit

-CHANGELOG
-=========
-
-2.5.0
------
-
-* [BC BREAK] The default value for checkbox and radio inputs without a value attribute have changed
-  from '1' to 'on' to match the HTML specification.
-* [BC BREAK] The typehints on the `Link`, `Form` and `FormField` classes have been changed from
-  `\DOMNode` to `DOMElement`. Using any other type of `DOMNode` was triggering fatal errors in previous
-  versions. Code extending these classes will need to update the typehints when overwriting these methods.
-
-2.4.0
------
-
- * `Crawler::addXmlContent()` removes the default document namespace again if it's an only namespace.
- * added support for automatic discovery and explicit registration of document
-   namespaces for `Crawler::filterXPath()` and `Crawler::filter()`
- * improved content type guessing in `Crawler::addContent()`
- * [BC BREAK] `Crawler::addXmlContent()` no longer removes the default document
-   namespace
-
-2.3.0
------
-
- * added Crawler::html()
- * [BC BREAK] Crawler::each() and Crawler::reduce() now return Crawler instances instead of DomElement instances
- * added schema relative URL support to links
- * added support for HTML5 'form' attribute
-
-2.2.0
------
-
- * added a way to set raw path to the file in FileFormField - necessary for
-   simulating HTTP requests
-
-2.1.0
------
-
- * added support for the HTTP PATCH method
- * refactored the Form class internals to support multi-dimensional fields
-   (the public API is backward compatible)
- * added a way to get parsing errors for Crawler::addHtmlContent() and
-   Crawler::addXmlContent() via libxml functions
- * added support for submitting a form without a submit button

-DomCrawler Component
-====================
-
-DomCrawler eases DOM navigation for HTML and XML documents.
-
-If you are familiar with jQuery, DomCrawler is a PHP equivalent:
-
-```php
-use Symfony\Component\DomCrawler\Crawler;
-
-$crawler = new Crawler();
-$crawler->addContent('<html><body><p>Hello World!</p></body></html>');
-
-print $crawler->filterXPath('descendant-or-self::body/p')->text();
-```
-
-If you are also using the CssSelector component, you can use CSS Selectors
-instead of XPath expressions:
-
-```php
-use Symfony\Component\DomCrawler\Crawler;
-
-$crawler = new Crawler();
-$crawler->addContent('<html><body><p>Hello World!</p></body></html>');
-
-print $crawler->filter('body > p')->text();
-```
-
-Resources
----------
-
-You can run the unit tests with the following command:
-
-    $ cd path/to/Symfony/Component/DomCrawler/
-    $ composer install
-    $ phpunit

+DomCrawler Component
+====================
+
+DomCrawler eases DOM navigation for HTML and XML documents.
+
+If you are familiar with jQuery, DomCrawler is a PHP equivalent:
+
+    use Symfony\Component\DomCrawler\Crawler;
+
+    $crawler = new Crawler();
+    $crawler->addContent('<html><body><p>Hello World!</p></body></html>');
+
+    print $crawler->filterXPath('descendant-or-self::body/p')->text();
+
+If you are also using the CssSelector component, you can use CSS Selectors
+instead of XPath expressions:
+
+    use Symfony\Component\DomCrawler\Crawler;
+
+    $crawler = new Crawler();
+    $crawler->addContent('<html><body><p>Hello World!</p></body></html>');
+
+    print $crawler->filter('body > p')->text();
+
+Resources
+---------
+
+You can run the unit tests with the following command:
+
+    phpunit
+
+If you also want to run the unit tests that depend on other Symfony
+Components, install dev dependencies before running PHPUnit:
+
+    php composer.phar install --dev

+## Reporting Potential Security Issues
+
+If you have encountered a potential security vulnerability, please **DO NOT** report it on the public
+issue tracker: send it to us at [zf-security@zend.com](mailto:zf-security@zend.com) instead.
+We will work with you to verify the vulnerability and patch it as soon as possible.
+
+When reporting issues, please provide the following information:
+
+- Component(s) affected
+- A description indicating how to reproduce the issue
+- A summary of the security vulnerability and impact
+
+We request that you contact us via the email address above and give the project
+contributors a chance to resolve the vulnerability and issue a new release prior
+to any public exposure; this helps protect users and provides them with a chance
+to upgrade and/or update in order to protect their applications.
+
+For sensitive email communications, please use [our PGP key](http://framework.zend.com/zf-security-pgp-key.asc).
+
+## RUNNING TESTS
+
+> ### Note: testing versions prior to 2.4
+>
+> This component originates with Zend Framework 2. During the lifetime of ZF2,
+> testing infrastructure migrated from PHPUnit 3 to PHPUnit 4. In most cases, no
+> changes were necessary. However, due to the migration, tests may not run on
+> versions < 2.4. As such, you may need to change the PHPUnit dependency if
+> attempting a fix on such a version.
+
+To run tests:
+
+- Clone the repository:
+
+  ```console
+  $ git clone git@github.com:zendframework/zend-escaper.git
+  $ cd
+  ```
+
+- Install dependencies via composer:
+
+  ```console
+  $ curl -sS https://getcomposer.org/installer | php --
+  $ ./composer.phar install
+  ```
+
+  If you don't have `curl` installed, you can also download `composer.phar` from https://getcomposer.org/
+
+- Run the tests via `phpunit` and the provided PHPUnit config, like in this example:
+
+  ```console
+  $ ./vendor/bin/phpunit
+  ```
+
+You can turn on conditional tests with the phpunit.xml file.
+To do so:
+
+ -  Copy `phpunit.xml.dist` file to `phpunit.xml`
+ -  Edit `phpunit.xml` to enable any specific functionality you
+    want to test, as well as to provide test values to utilize.
+
+## Running Coding Standards Checks
+
+This component uses [php-cs-fixer](http://cs.sensiolabs.org/) for coding
+standards checks, and provides configuration for our selected checks.
+`php-cs-fixer` is installed by default via Composer.
+
+To run checks only:
+
+```console
+$ ./vendor/bin/php-cs-fixer fix . -v --diff --dry-run --config-file=.php_cs
+```
+
+To have `php-cs-fixer` attempt to fix problems for you, omit the `--dry-run`
+flag:
+
+```console
+$ ./vendor/bin/php-cs-fixer fix . -v --diff --config-file=.php_cs
+```
+
+If you allow php-cs-fixer to fix CS issues, please re-run the tests to ensure
+they pass, and make sure you add and commit the changes after verification.
+
+## Recommended Workflow for Contributions
+
+Your first step is to establish a public repository from which we can
+pull your work into the master repository. We recommend using
+[GitHub](https://github.com), as that is where the component is already hosted.
+
+1. Setup a [GitHub account](http://github.com/), if you haven't yet
+2. Fork the repository (http://github.com/zendframework/zend-escaper)
+3. Clone the canonical repository locally and enter it.
+
+   ```console
+   $ git clone git://github.com:zendframework/zend-escaper.git
+   $ cd zend-escaper
+   ```
+
+4. Add a remote to your fork; substitute your GitHub username in the command
+   below.
+
+   ```console
+   $ git remote add {username} git@github.com:{username}/zend-escaper.git
+   $ git fetch {username}
+   ```
+
+### Keeping Up-to-Date
+
+Periodically, you should update your fork or personal repository to
+match the canonical ZF repository. Assuming you have setup your local repository
+per the instructions above, you can do the following:
+
+
+```console
+$ git checkout master
+$ git fetch origin
+$ git rebase origin/master
+# OPTIONALLY, to keep your remote up-to-date -
+$ git push {username} master:master
+```
+
+If you're tracking other branches -- for example, the "develop" branch, where
+new feature development occurs -- you'll want to do the same operations for that
+branch; simply substitute  "develop" for "master".
+
+### Working on a patch
+
+We recommend you do each new feature or bugfix in a new branch. This simplifies
+the task of code review as well as the task of merging your changes into the
+canonical repository.
+
+A typical workflow will then consist of the following:
+
+1. Create a new local branch based off either your master or develop branch.
+2. Switch to your new local branch. (This step can be combined with the
+   previous step with the use of `git checkout -b`.)
+3. Do some work, commit, repeat as necessary.
+4. Push the local branch to your remote repository.
+5. Send a pull request.
+
+The mechanics of this process are actually quite trivial. Below, we will
+create a branch for fixing an issue in the tracker.
+
+```console
+$ git checkout -b hotfix/9295
+Switched to a new branch 'hotfix/9295'
+```
+
+... do some work ...
+
+
+```console
+$ git commit
+```
+
+... write your log message ...
+
+
+```console
+$ git push {username} hotfix/9295:hotfix/9295
+Counting objects: 38, done.
+Delta compression using up to 2 threads.
+Compression objects: 100% (18/18), done.
+Writing objects: 100% (20/20), 8.19KiB, done.
+Total 20 (delta 12), reused 0 (delta 0)
+To ssh://git@github.com/{username}/zend-escaper.git
+   b5583aa..4f51698  HEAD -> master
+```
+
+To send a pull request, you have two options.
+
+If using GitHub, you can do the pull request from there. Navigate to
+your repository, select the branch you just created, and then select the
+"Pull Request" button in the upper right. Select the user/organization
+"zendframework" as the recipient.
+
+If using your own repository - or even if using GitHub - you can use `git
+format-patch` to create a patchset for us to apply; in fact, this is
+**recommended** for security-related patches. If you use `format-patch`, please
+send the patches as attachments to:
+
+-  zf-devteam@zend.com for patches without security implications
+-  zf-security@zend.com for security patches
+
+#### What branch to issue the pull request against?
+
+Which branch should you issue a pull request against?
+
+- For fixes against the stable release, issue the pull request against the
+  "master" branch.
+- For new features, or fixes that introduce new elements to the public API (such
+  as new public methods or properties), issue the pull request against the
+  "develop" branch.
+
+### Branch Cleanup
+
+As you might imagine, if you are a frequent contributor, you'll start to
+get a ton of branches both locally and on your remote.
+
+Once you know that your changes have been accepted to the master
+repository, we suggest doing some cleanup of these branches.
+
+-  Local branch cleanup
+
+   ```console
+   $ git branch -d <branchname>
+   ```
+
+-  Remote branch removal
+
+   ```console
+   $ git push {username} :<branchname>
+   ```

-Escaper Component from ZF2
-==========================
+# zend-escaper
 
-This is the Escaper component for ZF2.
+The OWASP Top 10 web security risks study lists Cross-Site Scripting (XSS) in
+second place. PHP’s sole functionality against XSS is limited to two functions
+of which one is commonly misapplied. Thus, the `Zend\Escaper` component was written.
+It offers developers a way to escape output and defend from XSS and related
+vulnerabilities by introducing contextual escaping based on peer-reviewed rules.

+When reporting issues, please provide the following information:
+
+- Component(s) affected
+- A description indicating how to reproduce the issue
+- A summary of the security vulnerability and impact
+
+We request that you contact us via the email address above and give the project
+contributors a chance to resolve the vulnerability and issue a new release prior
+to any public exposure; this helps protect users and provides them with a chance
+to upgrade and/or update in order to protect their applications.

+
+## RUNNING TESTS
+
+> ### Note: testing versions prior to 2.4
+>
+> This component originates with Zend Framework 2. During the lifetime of ZF2,
+> testing infrastructure migrated from PHPUnit 3 to PHPUnit 4. In most cases, no
+> changes were necessary. However, due to the migration, tests may not run on
+> versions < 2.4. As such, you may need to change the PHPUnit dependency if
+> attempting a fix on such a version.
+
+To run tests:
+
+- Clone the repository:
+
+  ```console
+  $ git clone git@github.com:zendframework/zend-feed.git
+  $ cd
+  ```
+
+- Install dependencies via composer:
+
+  ```console
+  $ curl -sS https://getcomposer.org/installer | php --
+  $ ./composer.phar install
+  ```
+
+  If you don't have `curl` installed, you can also download `composer.phar` from https://getcomposer.org/
+
+- Run the tests via `phpunit` and the provided PHPUnit config, like in this example:
+
+  ```console
+  $ ./vendor/bin/phpunit
+  ```
+
+You can turn on conditional tests with the phpunit.xml file.
+To do so:
+
+ -  Copy `phpunit.xml.dist` file to `phpunit.xml`
+ -  Edit `phpunit.xml` to enable any specific functionality you
+    want to test, as well as to provide test values to utilize.
+
+## Running Coding Standards Checks
+
+This component uses [php-cs-fixer](http://cs.sensiolabs.org/) for coding
+standards checks, and provides configuration for our selected checks.
+`php-cs-fixer` is installed by default via Composer.
+
+To run checks only:
+
+```console
+$ ./vendor/bin/php-cs-fixer fix . -v --diff --dry-run --config-file=.php_cs
+```
+
+To have `php-cs-fixer` attempt to fix problems for you, omit the `--dry-run`
+flag:
+
+```console
+$ ./vendor/bin/php-cs-fixer fix . -v --diff --config-file=.php_cs
+```
+
+If you allow php-cs-fixer to fix CS issues, please re-run the tests to ensure
+they pass, and make sure you add and commit the changes after verification.
+
+## Recommended Workflow for Contributions
+
+Your first step is to establish a public repository from which we can
+pull your work into the master repository. We recommend using
+[GitHub](https://github.com), as that is where the component is already hosted.
+
+1. Setup a [GitHub account](http://github.com/), if you haven't yet
+2. Fork the repository (http://github.com/zendframework/zend-feed)
+3. Clone the canonical repository locally and enter it.
+
+   ```console
+   $ git clone git://github.com:zendframework/zend-feed.git
+   $ cd zend-feed
+   ```
+
+4. Add a remote to your fork; substitute your GitHub username in the command
+   below.
+
+   ```console
+   $ git remote add {username} git@github.com:{username}/zend-feed.git
+   $ git fetch {username}
+   ```
+
+### Keeping Up-to-Date
+
+Periodically, you should update your fork or personal repository to
+match the canonical ZF repository. Assuming you have setup your local repository
+per the instructions above, you can do the following:
+
+
+```console
+$ git checkout master
+$ git fetch origin
+$ git rebase origin/master
+# OPTIONALLY, to keep your remote up-to-date -
+$ git push {username} master:master
+```
+
+If you're tracking other branches -- for example, the "develop" branch, where
+new feature development occurs -- you'll want to do the same operations for that
+branch; simply substitute  "develop" for "master".
+
+### Working on a patch
+
+We recommend you do each new feature or bugfix in a new branch. This simplifies
+the task of code review as well as the task of merging your changes into the
+canonical repository.
+
+A typical workflow will then consist of the following:
+
+1. Create a new local branch based off either your master or develop branch.
+2. Switch to your new local branch. (This step can be combined with the
+   previous step with the use of `git checkout -b`.)
+3. Do some work, commit, repeat as necessary.
+4. Push the local branch to your remote repository.
+5. Send a pull request.
+
+The mechanics of this process are actually quite trivial. Below, we will
+create a branch for fixing an issue in the tracker.
+
+```console
+$ git checkout -b hotfix/9295
+Switched to a new branch 'hotfix/9295'
+```
+
+... do some work ...
+
+
+```console
+$ git commit
+```
+
+... write your log message ...
+
+
+```console
+$ git push {username} hotfix/9295:hotfix/9295
+Counting objects: 38, done.
+Delta compression using up to 2 threads.
+Compression objects: 100% (18/18), done.
+Writing objects: 100% (20/20), 8.19KiB, done.
+Total 20 (delta 12), reused 0 (delta 0)
+To ssh://git@github.com/{username}/zend-feed.git
+   b5583aa..4f51698  HEAD -> master
+```
+
+To send a pull request, you have two options.
+
+If using GitHub, you can do the pull request from there. Navigate to
+your repository, select the branch you just created, and then select the
+"Pull Request" button in the upper right. Select the user/organization
+"zendframework" as the recipient.
+
+If using your own repository - or even if using GitHub - you can use `git
+format-patch` to create a patchset for us to apply; in fact, this is
+**recommended** for security-related patches. If you use `format-patch`, please
+send the patches as attachments to:
+
+-  zf-devteam@zend.com for patches without security implications
+-  zf-security@zend.com for security patches
+
+#### What branch to issue the pull request against?
+
+Which branch should you issue a pull request against?
+
+- For fixes against the stable release, issue the pull request against the
+  "master" branch.
+- For new features, or fixes that introduce new elements to the public API (such
+  as new public methods or properties), issue the pull request against the
+  "develop" branch.
+
+### Branch Cleanup
+
+As you might imagine, if you are a frequent contributor, you'll start to
+get a ton of branches both locally and on your remote.
+
+Once you know that your changes have been accepted to the master
+repository, we suggest doing some cleanup of these branches.
+
+-  Local branch cleanup
+
+   ```console
+   $ git branch -d <branchname>
+   ```
+
+-  Remote branch removal
+
+   ```console
+   $ git push {username} :<branchname>
+   ```

-Feed Component from ZF2
-=======================
+# zend-feed
 
-This is the Feed component for ZF2.
+`Zend\Feed` provides functionality for consuming RSS and Atom feeds. It provides
+a natural syntax for accessing elements of feeds, feed attributes, and entry
+attributes. `Zend\Feed` also has extensive support for modifying feed and entry
+structure with the same natural syntax, and turning the result back into XML.

+
+## RUNNING TESTS
+
+> ### Note: testing versions prior to 2.4
+>
+> This component originates with Zend Framework 2. During the lifetime of ZF2,
+> testing infrastructure migrated from PHPUnit 3 to PHPUnit 4. In most cases, no
+> changes were necessary. However, due to the migration, tests may not run on
+> versions < 2.4. As such, you may need to change the PHPUnit dependency if
+> attempting a fix on such a version.
+
+To run tests:
+
+- Clone the repository:
+
+  ```console
+  $ git clone git@github.com:zendframework/zend-stdlib.git
+  $ cd
+  ```
+
+- Install dependencies via composer:
+
+  ```console
+  $ curl -sS https://getcomposer.org/installer | php --
+  $ ./composer.phar install
+  ```
+
+  If you don't have `curl` installed, you can also download `composer.phar` from https://getcomposer.org/
+
+- Run the tests via `phpunit` and the provided PHPUnit config, like in this example:
+
+  ```console
+  $ ./vendor/bin/phpunit
+  ```
+
+You can turn on conditional tests with the phpunit.xml file.
+To do so:
+
+ -  Copy `phpunit.xml.dist` file to `phpunit.xml`
+ -  Edit `phpunit.xml` to enable any specific functionality you
+    want to test, as well as to provide test values to utilize.
+
+## Running Coding Standards Checks
+
+This component uses [php-cs-fixer](http://cs.sensiolabs.org/) for coding
+standards checks, and provides configuration for our selected checks.
+`php-cs-fixer` is installed by default via Composer.
+
+To run checks only:
+
+```console
+$ ./vendor/bin/php-cs-fixer fix . -v --diff --dry-run --config-file=.php_cs
+```
+
+To have `php-cs-fixer` attempt to fix problems for you, omit the `--dry-run`
+flag:
+
+```console
+$ ./vendor/bin/php-cs-fixer fix . -v --diff --config-file=.php_cs
+```
+
+If you allow php-cs-fixer to fix CS issues, please re-run the tests to ensure
+they pass, and make sure you add and commit the changes after verification.
+
+## Recommended Workflow for Contributions
+
+Your first step is to establish a public repository from which we can
+pull your work into the master repository. We recommend using
+[GitHub](https://github.com), as that is where the component is already hosted.
+
+1. Setup a [GitHub account](http://github.com/), if you haven't yet
+2. Fork the repository (http://github.com/zendframework/zend-stdlib)
+3. Clone the canonical repository locally and enter it.
+
+   ```console
+   $ git clone git://github.com:zendframework/zend-stdlib.git
+   $ cd zend-stdlib
+   ```
+
+4. Add a remote to your fork; substitute your GitHub username in the command
+   below.
+
+   ```console
+   $ git remote add {username} git@github.com:{username}/zend-stdlib.git
+   $ git fetch {username}
+   ```
+
+### Keeping Up-to-Date
+
+Periodically, you should update your fork or personal repository to
+match the canonical ZF repository. Assuming you have setup your local repository
+per the instructions above, you can do the following:
+
+
+```console
+$ git checkout master
+$ git fetch origin
+$ git rebase origin/master
+# OPTIONALLY, to keep your remote up-to-date -
+$ git push {username} master:master
+```
+
+If you're tracking other branches -- for example, the "develop" branch, where
+new feature development occurs -- you'll want to do the same operations for that
+branch; simply substitute  "develop" for "master".
+
+### Working on a patch
+
+We recommend you do each new feature or bugfix in a new branch. This simplifies
+the task of code review as well as the task of merging your changes into the
+canonical repository.
+
+A typical workflow will then consist of the following:
+
+1. Create a new local branch based off either your master or develop branch.
+2. Switch to your new local branch. (This step can be combined with the
+   previous step with the use of `git checkout -b`.)
+3. Do some work, commit, repeat as necessary.
+4. Push the local branch to your remote repository.
+5. Send a pull request.
+
+The mechanics of this process are actually quite trivial. Below, we will
+create a branch for fixing an issue in the tracker.
+
+```console
+$ git checkout -b hotfix/9295
+Switched to a new branch 'hotfix/9295'
+```
+
+... do some work ...
+
+
+```console
+$ git commit
+```
+
+... write your log message ...
+
+
+```console
+$ git push {username} hotfix/9295:hotfix/9295
+Counting objects: 38, done.
+Delta compression using up to 2 threads.
+Compression objects: 100% (18/18), done.
+Writing objects: 100% (20/20), 8.19KiB, done.
+Total 20 (delta 12), reused 0 (delta 0)
+To ssh://git@github.com/{username}/zend-stdlib.git
+   b5583aa..4f51698  HEAD -> master
+```
+
+To send a pull request, you have two options.
+
+If using GitHub, you can do the pull request from there. Navigate to
+your repository, select the branch you just created, and then select the
+"Pull Request" button in the upper right. Select the user/organization
+"zendframework" as the recipient.
+
+If using your own repository - or even if using GitHub - you can use `git
+format-patch` to create a patchset for us to apply; in fact, this is
+**recommended** for security-related patches. If you use `format-patch`, please
+send the patches as attachments to:
+
+-  zf-devteam@zend.com for patches without security implications
+-  zf-security@zend.com for security patches
+
+#### What branch to issue the pull request against?
+
+Which branch should you issue a pull request against?
+
+- For fixes against the stable release, issue the pull request against the
+  "master" branch.
+- For new features, or fixes that introduce new elements to the public API (such
+  as new public methods or properties), issue the pull request against the
+  "develop" branch.
+
+### Branch Cleanup
+
+As you might imagine, if you are a frequent contributor, you'll start to
+get a ton of branches both locally and on your remote.
+
+Once you know that your changes have been accepted to the master
+repository, we suggest doing some cleanup of these branches.
+
+-  Local branch cleanup
+
+   ```console
+   $ git branch -d <branchname>
+   ```
+
+-  Remote branch removal
+
+   ```console
+   $ git push {username} :<branchname>
+   ```
