Classes
\Composer\Autoload\ClassLoader
See https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-0.md
$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.
