+=head3 Cascading configuration.
+The config method is present on all Catalyst components, and configuration
+will be merged when an application is started. Configuration loaded with
+L<Catalyst::Plugin::ConfigLoader> takes precedence over other configuration,
+followed by configuration in your top level C<MyApp> class. These two
+configurations are merged, and then configuration data whose hash key matches a
+component name is merged with configuration for that component.
+
+The configuration for a component is then passed to the C<new> method when a
+component is constructed.
+
+For example:
+
+ MyApp->config({ 'Model::Foo' => { bar => 'baz', overrides => 'me' } });
+ MyApp::Model::Foo->config({ quux => 'frob', 'overrides => 'this' });
+
+will mean that C<MyApp::Model::Foo> receives the following data when
+constructed:
+
+ MyApp::Model::Foo->new({
+ bar => 'baz',
+ quux => 'frob',
+ overrides => 'me',
