Fabien Potencier has posted the second part of his "packing a Symfony app in one file" series with this look at the bootstrapping of the application. You can find the start of the series (including his intentions) in part one.

The most common way to create a Symfony project is to start with the Symfony Standard Edition: it defines a sensible directory structure for your project and it make things a lot easier when someone want to take over an existing project as he knows where the templates, the controllers, or the configuration are stored.

This part of the series looks at some of the configurations and settings you'll need to get the application up and working in a minimal way. This includes moving everything into one YAML configuration file including routing information. He shows how some bundles, bootstrap code and things to remove from the composer config.
