- *
- * 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.
