+it works transparently without your intervention. For example, when you
+use the <a class="reference internal" href="loader.html"><em>Loader</em></a> class to load a view file,
+it&#8217;s automatically passed to the Output class, which will be called
+automatically by CodeIgniter at the end of system execution. It is
