The "C<$c>" here refers to the Catalyst context, which is used to access
the Catalyst application. In addition to many other things, the Catalyst
context provides access to "response" and "request" objects. (See
-L<Catalyst>, L<Catalyst::Response>, and
+L<Catalyst::Runtime>, L<Catalyst::Response>, and
L<Catalyst::Request>)
C<$c-E<gt>response-E<gt>body> sets the HTTP response (see
to the package C<Hello::Controller::Admin::Articles>, and the C<create>
method.

this is not a TT tutorial, we'll stick to only basic TT usage here (and
explore some of the more common TT features in later chapters of the
