+Locating Resources
+------------------
+
+The HttpKernel component is responsible of the bundle mechanism used in Symfony
+applications. The key feature of the bundles is that they allow to override any
+resource used by the application (config files, templates, controllers,
+translation files, etc.)
+
+This overriding mechanism works because resources are referenced not by their
+physical path but by their logical path. For example, the ``services.xml`` file
+stored in the ``Resources/config/`` directory of a bundle called AppBundle is
+referenced as ``@AppBundle/Resources/config/services.xml``. This logical path
+will work when the application overrides that file and even if you change the
+directory of AppBundle.
+
+The HttpKernel component provides a method called :method:`Symfony\\Component\\HttpKernel\\Kernel::locateResource`
+which can be used to transform logical paths into physical paths::
+
+    use Symfony\Component\HttpKernel\HttpKernel;
+

-
-.. caution::

-.. sidebar:: More about ``doctrine:generate:entities``
-
-    With the ``doctrine:generate:entities`` command you can:
-
-    * generate getter and setter methods in entity classes;
-
-    * generate repository classes on behalf of entities configured with the
-      ``@ORM\Entity(repositoryClass="...")`` annotation;
-
-    * generate the appropriate constructor for 1:n and n:m relations.
-
-    The ``doctrine:generate:entities`` command saves a backup of the original
-    ``Product.php`` named ``Product.php~``. In some cases, the presence of
-    this file can cause a "Cannot redeclare class" error. It can be safely
-    removed. You can also use the ``--no-backup`` option to prevent generating
-    these backup files.
-
-    Note that you don't *need* to use this command. You could also write the
-    necessary getters and setters by hand. This option simply exists to save
-    you time, since creating these methods is often a common task during
-    development.
-
-You can also generate all known entities (i.e. any PHP class with Doctrine
-mapping information) of a bundle or an entire namespace:
