- * 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.
