* In this example, if you try to use a class in the Symfony\Component

[29] Fix | Delete

* namespace or one of its children (Symfony\Component\Console for instance),

[30] Fix | Delete

* the autoloader will first look for the class under the component/

[32] Fix | Delete

* found before giving up.

[34] Fix | Delete

* This class is loosely based on the Symfony UniversalClassLoader.
