/**
* 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>

CHANGELOG
=========
2.4.0
-----
* deprecated the UniversalClassLoader in favor of the ClassLoader class instead
* deprecated the ApcUniversalClassLoader in favor of the ApcClassLoader class instead
* deprecated the DebugUniversalClassLoader in favor of the DebugClassLoader class from the Debug component
* deprecated the DebugClassLoader as it has been moved to the Debug component instead
2.3.0
-----
* added a WinCacheClassLoader for WinCache
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

* 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.
*
