+ *
+ *     $loader = new \Composer\Autoload\ClassLoader();
+ *
+ *     // register classes with namespaces
+ *     $loader->add('Symfony\Component', __DIR__.'/component');
+ *     $loader->add('Symfony',           __DIR__.'/framework');
+ *
+ *     // activate the autoloader
+ *     $loader->register();
+ *
+ *     // to enable searching the include path (eg. for PEAR packages)
+ *     $loader->setUseIncludePath(true);
+ *
+ * In this example, if you try to use a class in the Symfony\Component
+ * namespace or one of its children (Symfony\Component\Console for instance),
+ * the autoloader will first look for the class under the component/
+ * directory, and it will then fallback to the framework/ directory if not
+ * found before giving up.
+ *
+ * This class is loosely based on the Symfony UniversalClassLoader.

+# Upgrade to 1.4
+
+## Minor BC Break: `Doctrine\Common\Cache\FileCache#$extension` is now `private`.
+
+If you need to override the value of `Doctrine\Common\Cache\FileCache#$extension`, then use the
+second parameter of `Doctrine\Common\Cache\FileCache#__construct()` instead of overriding
+the property in your own implementation.
+
+## Minor BC Break: file based caches paths changed
+
+`Doctrine\Common\Cache\FileCache`, `Doctrine\Common\Cache\PhpFileCache` and
+`Doctrine\Common\Cache\FilesystemCache` are using a different cache paths structure.
+
+If you rely on warmed up caches for deployments, consider that caches generated
+with `doctrine/cache` `<1.4` are not compatible with the new directory structure,
+and will be ignored.

+=======================
+Guzzle Cache Subscriber
+=======================
+
+.. important::
+
+    **This repo has not been updated for Guzzle 6 and only supports Guzzle 5.**
+
+    See https://github.com/Kevinrob/guzzle-cache-middleware for a nice Guzzle 6
+    compatible Cache middleware.
+
+Provides a private transparent proxy cache for caching HTTP responses.
+
+Here's a simple example of how it's used:
+
+.. code-block:: php
+
+    use GuzzleHttp\Client;
+    use GuzzleHttp\Subscriber\Cache\CacheSubscriber;
+
+    $client = new Client(['defaults' => ['debug' => true]]);
+
+    // Use the helper method to attach a cache to the client.
+    CacheSubscriber::attach($client);
+
+    // Send the first request
+    $a = $client->get('http://en.wikipedia.org/wiki/Main_Page');
+
+    // Send the second request. This will find a cache hit which must be
+    // validated. The validation request returns a 304, which yields the original
+    // cached response.
+    $b = $client->get('http://en.wikipedia.org/wiki/Main_Page');
+
+Running the above code sample should output verbose cURL information that looks
+something like this:
+
+::
+
+    > GET /wiki/Main_Page HTTP/1.1
+    Host: en.wikipedia.org

+
+Installing
+----------
+
+Add the following to your composer.json:
+
+.. code-block:: javascript
+
+    {
+        "require": {
+            "guzzlehttp/cache-subscriber": "0.2.*@dev"
+        }
+    }
+
+or
+
+.. code-block:: console
+
+    $ composer require guzzlehttp/cache-subscriber
+
+Creating a CacheSubscriber
+--------------------------
+
+The easiest way to create a CacheSubscriber is using the ``attach()`` helper
+method of ``GuzzleHttp\Subscriber\Cache\CacheSubscriber``. This method accepts
+a request or client object and attaches the necessary subscribers used to
+perform cache lookups, validation requests, and automatic purging of resources.
+
+The ``attach()`` method accepts the following options:
+
+storage
+    A ``GuzzleHttp\Subscriber\Cache\CacheStorageInterface`` object used to
+    store cached responses. If no value is not provided, an in-memory array
+    cache will be used.
+validate
+    A Boolean value that determines if cached response are ever validated
+    against the origin server. This setting defaults to ``true`` but can be
+    disabled by passing ``false``.
+purge
+    A Boolean value that determines if cached responses are purged when
+    non-idempotent requests are sent to their URI. This setting defaults to
+    ``true`` but can be disabled by passing ``false``.
+can_cache
+    An optional callable used to determine if a request can be cached. The
+    callable accepts a ``GuzzleHttp\Message\RequestInterface`` and returns a
+    Boolean value. If no value is provided, the default behavior is utilized.
+
+.. warning::
+
+    This is a WIP update for Guzzle 5+. It hasn't been tested and is in
+    active development. Expect bugs and breaks.

+Guzzle, PHP HTTP client and webservice framework
+================================================
+
+[![Build Status](https://secure.travis-ci.org/guzzle/guzzle.svg?branch=master)](http://travis-ci.org/guzzle/guzzle)
+
+Guzzle is a PHP HTTP client that makes it easy to send HTTP requests and
+trivial to integrate with web services.
+
+- Manages things like persistent connections, represents query strings as
+  collections, simplifies sending streaming POST requests with fields and
+  files, and abstracts away the underlying HTTP transport layer.
+- Can send both synchronous and asynchronous requests using the same interface
+  without requiring a dependency on a specific event loop.
+- Pluggable HTTP adapters allows Guzzle to integrate with any method you choose
+  for sending HTTP requests over the wire (e.g., cURL, sockets, PHP's stream
+  wrapper, non-blocking event loops like ReactPHP.
+- Guzzle makes it so that you no longer need to fool around with cURL options,
+  stream contexts, or sockets.
+
+```php
+$client = new GuzzleHttp\Client();
+$response = $client->get('http://guzzlephp.org');
+$res = $client->get('https://api.github.com/user', ['auth' =>  ['user', 'pass']]);
+echo $res->getStatusCode();
+// "200"
+echo $res->getHeader('content-type');
+// 'application/json; charset=utf8'
+echo $res->getBody();
+// {"type":"User"...'
+var_export($res->json());
+// Outputs the JSON decoded data
+
+// Send an asynchronous request.
+$req = $client->createRequest('GET', 'http://httpbin.org', ['future' => true]);
+$client->send($req)->then(function ($response) {
+    echo 'I completed! ' . $response;
+});
+```

+Get more information and answers with the
+[Documentation](http://guzzlephp.org/),
+[Forums](https://groups.google.com/forum/?hl=en#!forum/guzzle),
+and [Gitter](https://gitter.im/guzzle/guzzle).
+
+### Installing via Composer
+
+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
+composer.phar require guzzlehttp/guzzle
+```
+
+After installing, you need to require Composer's autoloader:
+
+```php
+require 'vendor/autoload.php';
+```
+
+### Documentation
+
+More information can be found in the online documentation at
+http://guzzlephp.org/.
