+      exists)
+  * [API break] Manager class API has been updated :
+    - The manager is mainly use to fill a Libray from a "library.xml" file or
+      opds feed. Other operations (has removeBookById, setBookPath, filter, ...)
+      have been removed.
+    - The manager use a intermediate class (LibraryManipulator) to add book to
+      the library. This dependency injection allow caller code to hook the add
+      of a book to the library.
+    - The manager work on a existing Library. It doesn't how a internal
+      Library.
+  * [API break] OpdsDumper class API has been updated :
