-Guzzle, PHP HTTP client
-=======================
-
-[![Build Status](https://travis-ci.org/guzzle/guzzle.svg?branch=master)](https://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.
-
-- 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/user', [
-    'auth' => ['user', 'pass']
-]);
-echo $res->getStatusCode();
-// 200
-echo $res->getHeaderLine('content-type');
-// 'application/json; charset=utf8'
-echo $res->getBody();
-// {"type":"User"...'
-
-// Send an asynchronous request.
-$request = new \GuzzleHttp\Psr7\Request('GET', 'http://httpbin.org');
-$promise = $client->sendAsync($request)->then(function ($response) {
-    echo 'I completed! ' . $response->getBody();
-});
-$promise->wait();
-```

-
-## 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
- ```
-

-# CHANGELOG
-
-
-## 1.3.1 - 2016-12-20
-
-### Fixed
-
-- `wait()` foreign promise compatibility
-
-
-## 1.3.0 - 2016-11-18
-
-### Added
-
-- Adds support for custom task queues.
-
-### Fixed
-
-- Fixed coroutine promise memory leak.
-
-
-## 1.2.0 - 2016-05-18
-
-### Changed
-
-- Update to now catch `\Throwable` on PHP 7+
-
-
-## 1.1.0 - 2016-03-07
-
-### Changed
-
-- Update EachPromise to prevent recurring on a iterator when advancing, as this
-  could trigger fatal generator errors.
-- Update Promise to allow recursive waiting without unwrapping exceptions.
-
-
-## 1.0.3 - 2015-10-15
-
-### Changed
-
-- Update EachPromise to immediately resolve when the underlying promise iterator
-  is empty. Previously, such a promise would throw an exception when its `wait`
-  function was called.
-
-
-## 1.0.2 - 2015-05-15
-
-### Changed
-
-- Conditionally require functions.php.
-
-
-## 1.0.1 - 2015-06-24
-
-### Changed
-
-- Updating EachPromise to call next on the underlying promise iterator as late
-  as possible to ensure that generators that generate new requests based on
-  callbacks are not iterated until after callbacks are invoked.
-
-
-## 1.0.0 - 2015-05-12
-
-- Initial release
