=head1 NAME
=head1 SYNOPSIS
-See L<Catalyst>.
+ package MyApp::Controller::Search
+ use base qw/Catalyst::Controller/;
+
+ sub foo : Local {
+ my ($self,$c,@args) = @_;
+ ...
+ } # Dispatches to /search/foo
=head1 DESCRIPTION
-Catalyst Controller base class.
+Controllers are where the actions in the Catalyst framework
+reside. Each action is represented by a function with an attribute to
+identify what kind of action it is. See the L<Catalyst::Dispatcher>
+for more info about how Catalyst dispatches to actions.

+=head1 CONFIGURATION
+
+Like any other L<Catalyst::Component>, controllers have a config hash,
+accessible through $self->config from the controller actions. Some
+settings are in use by the Catalyst framework:
+
+=head2 namespace
+
+This specifies the internal namespace the controller should be bound
+to. By default the controller is bound to the URI version of the
+controller name. For instance controller 'MyApp::Controller::Foo::Bar'
+will be bound to 'foo/bar'. The default Root controller is an example
+of setting namespace to '' (the null string).
+
+=head2 path
+
+Sets 'path_prefix', as described below.
+
+=head2 action
+
+Allows you to set the attributes that the dispatcher creates actions out of.
+This allows you to do 'rails style routes', or override some of the
+attribute definitions of actions composed from Roles.
+You can set arguments globally (for all actions of the controller) and
+specifically (for a single action).
+
+ __PACKAGE__->config(
+ action => {
+ '*' => { Chained => 'base', Args => 0 },
+ base => { Chained => '/', PathPart => '', CaptureArgs => 0 },
+ },
+ );
+
+In the case above every sub in the package would be made into a Chain
+endpoint with a URI the same as the sub name for each sub, chained
+to the sub named C<base>. Ergo dispatch to C</example> would call the
+C<base> method, then the C<example> method.
+
+=head2 action_args
+
+Allows you to set constructor arguments on your actions. You can set arguments
+globally and specifically (as above).
+This is particularly useful when using C<ActionRole>s
+(L<Catalyst::Controller::ActionRole>) and custom C<ActionClass>es.
+
+ __PACKAGE__->config(
+ action_args => {
+ '*' => { globalarg1 => 'hello', globalarg2 => 'goodbye' },
+ 'specific_action' => { customarg => 'arg1' },
+ },
+ );
+
+In the case above the action class associated with C<specific_action> would get
+passed the following arguments, in addition to the normal action constructor
+arguments, when it is instantiated:
+
+ (globalarg1 => 'hello', globalarg2 => 'goodbye', customarg => 'arg1')
+
+=head1 METHODS
+
+=head2 BUILDARGS ($app, @args)
+
+From L<Catalyst::Component::ApplicationAttribute>, stashes the application
+instance as $self->_application.
+
+=head2 $self->action_for('name')
+
+Returns the Catalyst::Action object (if any) for a given method name
+in this component.
+
+=head2 $self->action_namespace($c)
+
+Returns the private namespace for actions in this component. Defaults
+to a value from the controller name (for
+e.g. MyApp::Controller::Foo::Bar becomes "foo/bar") or can be
+overridden from the "namespace" config key.
+
+
+=head2 $self->path_prefix($c)
+
+Returns the default path prefix for :PathPrefix, :Local, :LocalRegex and
+relative :Path actions in this component. Defaults to the action_namespace or
+can be overridden from the "path" config key.
+
+=head2 $self->register_actions($c)
+
+Finds all applicable actions for this component, creates
+Catalyst::Action objects (using $self->create_action) for them and
+registers them with $c->dispatcher.
+
+=head2 $self->get_action_methods()
+
+Returns a list of L<Moose::Meta::Method> objects, doing the
+L<MooseX::MethodAttributes::Role::Meta::Method> role, which are the set of
+action methods for this package.
+
+=head2 $self->register_action_methods($c, @methods)
+
+Creates action objects for a set of action methods using C< create_action >,
+and registers them with the dispatcher.
+
+=head2 $self->action_class(%args)
+
+Used when a controller is creating an action to determine the correct base
+action class to use.
+
+=head2 $self->create_action(%args)
+
+Called with a hash of data to be use for construction of a new
+Catalyst::Action (or appropriate sub/alternative class) object.
+
+=head2 $self->_application
+
+=head2 $self->_app
+
+Returns the application instance stored by C<new()>
