end

Last configurable block to run. Called after frameworks initialize.

This allows you to modify application's generators from Railties.

Values set on #app_generators will become defaults for application, unless application overwrites them.

All operations you run on the #app_middleware will be replayed on the application once it is defined and the default_middlewares are created
