It happens more and more: large projects where your symfony2 site is just a small part in the big picture. Lots of additional components might even play a bigger part, especially when you are dealing with asynchronous components which are connected through message queues for instance. So the question is: we want to make sure that all your components are using the same settings, be it your symfony2 project, your bash-scripts, 3rd python application and whatnot. How do we keep this all in sync?
