=head1 DESCRIPTION
-The key concept of Catalyst is DRY (Don't Repeat Yourself).
+Catalyst is a modern framework for making web applications without the pain usually associated with this process. This document is a reference to the main Catalyst application. If you are a new user, we suggest you start with L<Catalyst::Manual::Tutorial> or L<Catalyst::Manual::Intro>
See L<Catalyst::Manual> for more documentation.
=head1 METHODS

-Forwards processing to a private action. 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<$c-E<gt>req-E<gt>args>. Upon returning from the function,
+Forwards processing to another action, by it's private name. If you give a
+class name but no method, C<process()> is called. You may also optionally
+pass arguments in an arrayref. The action will receive the arguments in
+C<@_> and C<$c-E<gt>req-E<gt>args>. Upon returning from the function,
C<$c-E<gt>req-E<gt>args> will be restored to the previous values.
Any data C<return>ed from the action forwarded to, will be returned by the

+ $c->forward(qw/MyApp::Model::DBIC::Foo do_stuff/);
$c->forward('MyApp::View::TT');
+Note that forward implies an C<<eval { }>> around the call (well, actually
+C<execute> 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:
