+ * 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';
+ *

+ *
+ *     $loader = new ApcUniversalClassLoader('apc.prefix.');
+ *
+ *     // register classes with namespaces
+ *     $loader->registerNamespaces(array(
+ *         'Symfony\Component' => __DIR__.'/component',
+ *         'Symfony'           => __DIR__.'/framework',

+ *     // 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.

+CHANGELOG
+=========
+
+2.1.0
+-----
+
+ * added a DebugClassLoader able to wrap any autoloader providing a findFile
+   method
+ * added a new ApcClassLoader and XcacheClassLoader using composition to wrap
+   other loaders
+ * added a new ClassLoader which does not distinguish between namespaced and
+   pear-like classes (as the PEAR convention is a subset of PSR-0) and
+   supports using Composer's namespace maps
+ * added a class map generator
+ * added support for loading globally-installed PEAR packages

+ClassLoader Component
+=====================
+
+ClassLoader loads your project classes automatically if they follow some
+standard PHP conventions.
+
+The Universal ClassLoader is able to autoload classes that implement the PSR-0
+standard or the PEAR naming convention.
+
+First, register the autoloader:
+
+    require_once __DIR__.'/src/Symfony/Component/ClassLoader/UniversalClassLoader.php';
+
+    use Symfony\Component\ClassLoader\UniversalClassLoader;
+
+    $loader = new UniversalClassLoader();
+    $loader->register();
+
+Then, register some namespaces with the `registerNamespace()` method:
+
+    $loader->registerNamespace('Symfony', __DIR__.'/src');
+    $loader->registerNamespace('Monolog', __DIR__.'/vendor/monolog/src');
+
+The `registerNamespace()` method takes a namespace prefix and a path where to
+look for the classes as arguments.
+
+You can also register a sub-namespaces:
+
+    $loader->registerNamespace('Doctrine\\Common', __DIR__.'/vendor/doctrine-common/lib');
+
+The order of registration is significant and the first registered namespace
+takes precedence over later registered one.
+
+You can also register more than one path for a given namespace:
+
+    $loader->registerNamespace('Symfony', array(__DIR__.'/src', __DIR__.'/symfony/src'));
+
+Alternatively, you can use the `registerNamespaces()` method to register more
+than one namespace at once:
+
+    $loader->registerNamespaces(array(
+        'Symfony'          => array(__DIR__.'/src', __DIR__.'/symfony/src'),
+        'Doctrine\\Common' => __DIR__.'/vendor/doctrine-common/lib',
+        'Doctrine'         => __DIR__.'/vendor/doctrine/lib',
+        'Monolog'          => __DIR__.'/vendor/monolog/src',
+    ));
+
+For better performance, you can use the APC based version of the universal
+class loader:
+
+    require_once __DIR__.'/src/Symfony/Component/ClassLoader/UniversalClassLoader.php';
+    require_once __DIR__.'/src/Symfony/Component/ClassLoader/ApcUniversalClassLoader.php';
+
+    use Symfony\Component\ClassLoader\ApcUniversalClassLoader;
+
+    $loader = new ApcUniversalClassLoader('apc.prefix.');
+
+Furthermore, the component provides tools to aggregate classes into a single
+file, which is especially useful to improve performance on servers that do not
+provide byte caches.
+
+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

+/**
+ * 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.
