8 # In Rails 3.0, a Rails::Application object was introduced which is nothing more than
9 # an Engine but with the responsibility of coordinating the whole boot process.
10 #
11 # == Initialization
12 #
13 # Rails::Application is responsible for executing all railties, engines and plugin
14 # initializers. Besides, it also executed some bootstrap initializers (check
15 # Rails::Application::Bootstrap) and finishing initializers, after all the others
16 # are executed (check Rails::Application::Finisher).
17 #
18 # == Configuration
19 #
20 # Besides providing the same configuration as Rails::Engine and Rails::Railtie,
21 # the application object has several specific configurations, for example
22 # "allow_concurrency", "cache_classes", "consider_all_requests_local", "filter_parameters",

30 # whenever the files change in development.

65 # Notice this method takes into consideration the default root path. So if you

68 # you need to load files in lib/ during the application configuration as well.
