=head1 METHODS
-=head2 INFORMATION ABOUT THE CURRENT REQUEST
-
-=head2 $c->action
-
-Returns a L<Catalyst::Action> object for the current action, which
-stringifies to the action name. See L<Catalyst::Action>.
-
-=head2 $c->namespace
-
-Returns the namespace of the current action, i.e., the URI prefix
-corresponding to the controller of the current action. For example:
-
- # in Controller::Foo::Bar
- $c->namespace; # returns 'foo/bar';
-
-=head2 $c->request
-
-=head2 $c->req
-
-Returns the current L<Catalyst::Request> object, giving access to
-information about the current client request (including parameters,
-cookies, HTTP headers, etc.). See L<Catalyst::Request>.
-
-=head2 REQUEST FLOW HANDLING
-
-=head2 $c->forward( $action [, \@arguments ] )
-
-=head2 $c->forward( $class, $method, [, \@arguments ] )
-
-Forwards processing to another action, by its private name. If you give a
-class name but no method, C<process()> is called. You may also optionally
-pass arguments in an arrayref. The action will receive the arguments in
-C<@_> and C<< $c->req->args >>. Upon returning from the function,
-C<< $c->req->args >> will be restored to the previous values.
-
-Any data C<return>ed from the action forwarded to, will be returned by the
-call to forward.
-
- my $foodata = $c->forward('/foo');
- $c->forward('index');
- $c->forward(qw/MyApp::Model::DBIC::Foo do_stuff/);
- $c->forward('MyApp::View::TT');
-
-Note that L<< forward|/"$c->forward( $action [, \@arguments ] )" >> implies
-an C<< eval { } >> around the call (actually
-L<< execute|/"$c->execute( $class, $coderef )" >> does), thus de-fatalizing
-all 'dies' within the called action. If you want C<die> to propagate you
-need to do something like:
-
- $c->forward('foo');
- die $c->error if $c->error;
-
-Or make sure to always return true values from your actions and write
-your code like this:
-
- $c->forward('foo') || return;
-
-=cut
-
-sub forward { my $c = shift; no warnings 'recursion'; $c->dispatcher->forward( $c, @_ ) }
-
-=head2 $c->detach( $action [, \@arguments ] )
-
-=head2 $c->detach( $class, $method, [, \@arguments ] )
-
-=head2 $c->detach()
-
-The same as L<< forward|/"$c->forward( $action [, \@arguments ] )" >>, but
-doesn't return to the previous action when processing is finished.
-
-When called with no arguments it escapes the processing chain entirely.
-
-=cut
-
-sub detach { my $c = shift; $c->dispatcher->detach( $c, @_ ) }
-
-=head2 $c->visit( $action [, \@captures, \@arguments ] )
-
-=head2 $c->visit( $class, $method, [, \@captures, \@arguments ] )
-
-Almost the same as L<< forward|/"$c->forward( $action [, \@arguments ] )" >>,
-but does a full dispatch, instead of just calling the new C<$action> /
-C<< $class->$method >>. This means that C<begin>, C<auto> and the method
-you go to are called, just like a new request.
-
-In addition both C<< $c->action >> and C<< $c->namespace >> are localized.
-This means, for example, that C<< $c->action >> methods such as
-L<name|Catalyst::Action/name>, L<class|Catalyst::Action/class> and
-L<reverse|Catalyst::Action/reverse> return information for the visited action
-when they are invoked within the visited action. This is different from the
-behavior of L<< forward|/"$c->forward( $action [, \@arguments ] )" >>, which
-continues to use the $c->action object from the caller action even when
-invoked from the callee.
-
-C<< $c->stash >> is kept unchanged.
-
-In effect, L<< visit|/"$c->visit( $action [, \@captures, \@arguments ] )" >>
-allows you to "wrap" another action, just as it would have been called by
-dispatching from a URL, while the analogous
-L<< go|/"$c->go( $action [, \@captures, \@arguments ] )" >> allows you to
-transfer control to another action as if it had been reached directly from a URL.

-
-=head2 $c->res
-
-Returns the current L<Catalyst::Response> object, see there for details.
-
-=head2 $c->stash
-
-Returns a hashref to the stash, which may be used to store data and pass
-it between components during a request. You can also set hash keys by
-passing arguments. The stash is automatically sent to the view. The
-stash is cleared at the end of a request; it cannot be used for
-persistent storage (for this you must use a session; see
-L<Catalyst::Plugin::Session> for a complete system integrated with
-Catalyst).

-method should only be used to store fatal error messages.

-=head2 $c->uri_for( $action, \@captures?, @args?, \%query_values? )
-
-Constructs an absolute L<URI> object based on the application root, the
-provided path, and the additional arguments and query parameters provided.
-When used as a string, provides a textual URI.
-
-If the first argument is a string, it is taken as a public URI path relative
-to C<< $c->namespace >> (if it doesn't begin with a forward slash) or
-relative to the application root (if it does). It is then merged with
-C<< $c->request->base >>; any C<@args> are appended as additional path
-components; and any C<%query_values> are appended as C<?foo=bar> parameters.
-
-If the first argument is a L<Catalyst::Action> it represents an action which
-will have its path resolved using C<< $c->dispatcher->uri_for_action >>. The
-optional C<\@captures> argument (an arrayref) allows passing the captured
-variables that are needed to fill in the paths of Chained and Regex actions;
-once the path is resolved, C<uri_for> continues as though a path was
-provided, appending any arguments or parameters and creating an absolute
-URI.
-
-The captures for the current request can be found in
-C<< $c->request->captures >>, and actions can be resolved using
-C<< Catalyst::Controller->action_for($name) >>. If you have a private action
-path, use C<< $c->uri_for_action >> instead.
