+=head1 NAME
+
+Catalyst::IOC - IOC for Catalyst, based on Bread::Board
+
+=head1 SYNOPSIS
+
+ package MyApp::Container;
+ use Moose;
+ use Catalyst::IOC;
+ extends 'Catalyst::IOC::Container';
+
+ container {
+ model {
+ # default component
+ component Foo => ();
+
+ # model Bar needs model Foo to be built before
+ # and Bar's constructor gets Foo as a parameter
+ component Bar => ( dependencies => [
+ depends_on('/model/Foo'),
+ ]);
+
+ # Baz is rebuilt once per HTTP request
+ component Baz => ( lifecycle => 'Request' );
+
+ # built only once per application life time
+ component Quux => ( lifecycle => 'Singleton' );
+
+ # built once per app life time and uses an external model,
+ # outside the default directory
+ # no need for wrappers or Catalyst::Model::Adaptor
+ component Fnar => (
+ lifecycle => 'Singleton',
+ class => 'My::External::Class',
+ );
+ };
+ view {
+ component HTML => ();
+ };
+ controller {
+ component Root => ();
+ };
+ }
+
+=head1 DESCRIPTION
+
+Catalyst::IOC provides "sugar" methods to extend the behavior of the default
+Catalyst container.
+
+=head1 METHODS
+
+=head2 container
+
+Sets up the root container to be customised.
+
+=head2 model
+
+Sets up the model container to be customised.
+
+=head2 view
+
+Sets up the view container to be customised.
+
+=head2 controller
+
+Sets up the controller container to be customised.
+
+=head2 component
+
+Adds a component to the sub-container. Works like L<Bread::Board::service>.
