+DependencyInjection Component
+=============================
+
+DependencyInjection manages your services via a robust and flexible Dependency
+Injection Container.
+
+Here is a simple example that shows how to register services and parameters:
+
+    use Symfony\Component\DependencyInjection\ContainerBuilder;
+    use Symfony\Component\DependencyInjection\Reference;
+
+    $sc = new ContainerBuilder();
+    $sc
+        ->register('foo', '%foo.class%')
+        ->addArgument(new Reference('bar'))
+    ;
+    $sc->setParameter('foo.class', 'Foo');
+
