16

17

18

19 
+ *
20 
+ *     // register classes with namespaces
21 
+ *     $loader->add('Symfony\Component', __DIR__.'/component');
22

25

30 
+ * In this example, if you try to use a class in the Symfony\Component
31 
+ * namespace or one of its children (Symfony\Component\Console for instance),
32 
+ * the autoloader will first look for the class under the component/
33 
+ * directory, and it will then fallback to the framework/ directory if not
34 
+ * found before giving up.
35 
+ *
36 
+ * This class is loosely based on the Symfony UniversalClassLoader.

- * In this example, if you try to use a class in the Symfony\Component
31 
- * namespace or one of its children (Symfony\Component\Console for instance),
32
