-/**
- * ApcUniversalClassLoader implements a "universal" autoloader cached in APC for PHP 5.3.
- *
- * It is able to load classes that use either:
- *
- *  * The technical interoperability standards for PHP 5.3 namespaces and
- *    class names (https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-0.md);
- *
- *  * The PEAR naming convention for classes (http://pear.php.net/).
- *
- * Classes from a sub-namespace or a sub-hierarchy of PEAR classes can be
- * looked for in a list of locations to ease the vendoring of a sub-set of
- * classes for large projects.
- *
- * Example usage:
- *
- *     require 'vendor/symfony/src/Symfony/Component/ClassLoader/UniversalClassLoader.php';
- *     require 'vendor/symfony/src/Symfony/Component/ClassLoader/ApcUniversalClassLoader.php';
- *
- *     use Symfony\Component\ClassLoader\ApcUniversalClassLoader;
- *
- *     $loader = new ApcUniversalClassLoader('apc.prefix.');
- *
- *     // register classes with namespaces
- *     $loader->registerNamespaces(array(
- *         'Symfony\Component' => __DIR__.'/component',
- *         'Symfony' => __DIR__.'/framework',
- *         'Sensio' => array(__DIR__.'/src', __DIR__.'/vendor'),
- *     ));
- *
- *     // register a library using the PEAR naming convention
- *     $loader->registerPrefixes(array(
- *         'Swift_' => __DIR__.'/Swift',
- *     ));
- *
- *     // activate the autoloader
- *     $loader->register();
- *
- * 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.
- *
- * @author Fabien Potencier <fabien@symfony.com>
- * @author Kris Wallsmith <kris@symfony.com>

-/**
- * UniversalClassLoader implements a "universal" autoloader for PHP 5.3.
- *
- * It is able to load classes that use either:
- *
- *  * The technical interoperability standards for PHP 5.3 namespaces and
- *    class names (https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-0.md);
- *
- *  * The PEAR naming convention for classes (http://pear.php.net/).
- *
- * Classes from a sub-namespace or a sub-hierarchy of PEAR classes can be
- * looked for in a list of locations to ease the vendoring of a sub-set of
- * classes for large projects.
- *
- * Example usage:
- *
- *     $loader = new UniversalClassLoader();
- *
- *     // register classes with namespaces
- *     $loader->registerNamespaces(array(
- *         'Symfony\Component' => __DIR__.'/component',
- *         'Symfony' => __DIR__.'/framework',
- *         'Sensio' => array(__DIR__.'/src', __DIR__.'/vendor'),
- *     ));
- *
- *     // register a library using the PEAR naming convention
- *     $loader->registerPrefixes(array(
- *         'Swift_' => __DIR__.'/Swift',
- *     ));
- *
- *
- *     // to enable searching the include path (e.g. for PEAR packages)
- *     $loader->useIncludePath(true);
- *
- *     // activate the autoloader
- *     $loader->register();
- *
- * 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.
- *
- * @author Fabien Potencier <fabien@symfony.com>
- *
- * @deprecated since version 2.4, to be removed in 3.0.
- *             Use the {@link ClassLoader} class instead.
