+ * ClassLoader implements a PSR-0, PSR-4 and classmap class loader.
+ *
+ *     $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.

+composer/ca-bundle
+==================
+
+Small utility library that lets you find a path to the system CA bundle,
+and includes a fallback to the Mozilla CA bundle.
+
+Originally written as part of [composer/composer](https://github.com/composer/composer),
+now extracted and made available as a stand-alone library.
+
+
+Installation
+------------
+
+Install the latest version with:
+
+```bash
+$ composer require composer/ca-bundle
+```
+
+
+Requirements
+------------
+
+* PHP 5.3.2 is required but using the latest version of PHP is highly recommended.
+
+
+Basic usage
+-----------
+
+# `Composer\CaBundle\CaBundle`
+
+- `CaBundle::getSystemCaRootBundlePath()`: Returns the system CA bundle path, or a path to the bundled one as fallback
+- `CaBundle::getBundledCaBundlePath()`: Returns the path to the bundled CA file
+- `CaBundle::validateCaFile($filename)`: Validates a CA file using opensl_x509_parse only if it is safe to use
+- `CaBundle::isOpensslParseSafe()`: Test if it is safe to use the PHP function openssl_x509_parse()
+- `CaBundle::reset()`: Resets the static caches
+
+
+## To use with curl
+
+```php
+$curl = curl_init("https://example.org/");
+
+$caPathOrFile = \Composer\CaBundle\CaBundle::getSystemCaRootBundlePath();
+if (is_dir($caPathOrFile) || (is_link($caPathOrFile) && is_dir(readlink($caPathOrFile)))) {
+    curl_setopt($curl, CURLOPT_CAPATH, $caPathOrFile);
+} else {
+    curl_setopt($curl, CURLOPT_CAINFO, $caPathOrFile);
+}
+
+$result = curl_exec($curl);
+```
+
+## To use with php streams
+
+```php
+$opts = array(
+    'http' => array(
+        'method' => "GET"
+    )
+);
+
+$caPathOrFile = \Composer\CaBundle\CaBundle::getSystemCaRootBundlePath();
+if (is_dir($caPathOrFile) || (is_link($caPathOrFile) && is_dir(readlink($caPathOrFile)))) {
+    $opts['ssl']['capath'] = $caPathOrFile;
+} else {
+    $opts['ssl']['cafile'] = $caPathOrFile;
+}
+
+$context = stream_context_create($opts);
+$result = file_get_contents('https://example.com', false, $context);
+```
+
+## To use with Guzzle
+
+```php
+$client = new \GuzzleHttp\Client([
+    \GuzzleHttp\RequestOptions::VERIFY => \Composer\CaBundle\CaBundle::getSystemCaRootBundlePath()
+]);
+```

+composer/semver
+===============
+
+Semver library that offers utilities, version constraint parsing and validation.
+
+Originally written as part of [composer/composer](https://github.com/composer/composer),
+now extracted and made available as a stand-alone library.
+
+[![Build Status](https://travis-ci.org/composer/semver.svg?branch=master)](https://travis-ci.org/composer/semver)
+
+
+Installation
+------------
+
+Install the latest version with:
+
+```bash
+$ composer require composer/semver
+```
+
+
+Requirements
+------------
+
+* PHP 5.3.2 is required but using the latest version of PHP is highly recommended.
+
+
+Version Comparison
+------------------
+
+For details on how versions are compared, refer to the [Versions](https://getcomposer.org/doc/articles/versions.md)
+article in the documentation section of the [getcomposer.org](https://getcomposer.org) website.
+
+
+Basic usage
+-----------
+
+### Comparator
+
+The `Composer\Semver\Comparator` class provides the following methods for comparing versions:
+
+* greaterThan($v1, $v2)
+* greaterThanOrEqualTo($v1, $v2)
+* lessThan($v1, $v2)
+* lessThanOrEqualTo($v1, $v2)
+* equalTo($v1, $v2)
+* notEqualTo($v1, $v2)
+
+Each function takes two version strings as arguments. For example:
+
+```php
+use Composer\Semver\Comparator;
+
+Comparator::greaterThan('1.25.0', '1.24.0'); // 1.25.0 > 1.24.0
+```
+
+### Semver
+
+The `Composer\Semver\Semver` class provides the following methods:
+
+* satisfies($version, $constraints)
+* satisfiedBy($constraint, array $versions)
+* sort($versions)
+* rsort($versions)
+
+
