-h3. Using a Preinitializer
+h3. Running Code Before Rails
-Rails allows you to use a preinitializer to run code before the framework itself is loaded. If you save code in +RAILS_ROOT/config/preinitializer.rb+, that code will be the first thing loaded, before any of the framework components (Active Record, Action Pack, and so on.) If you want to change the behavior of one of the classes that is used in the initialization process, you can do so in this file.
+To run some code before Rails itself is loaded, simply put it above the call to
++require 'rails/all'+ in your +application.rb+.
h3. Configuring Rails Components
-In general, the work of configuring Rails means configuring the components of Rails, as well as configuring Rails itself. The +environment.rb+ and environment-specific configuration files (such as +config/environments/production.rb+) allow you to specify the various settings that you want to pass down to all of the components.
