Templates in CI

[eluser]scherman[/eluser]
Hi people. I use the Colin Williams's template for CI.
I red the user guide, but i didn't see how i can create another template.

I have the default template:

Code:

$template['default']['template'] = 'template.php';
$template['default']['regions'] = array(
   'header',
   'content',
   'footer',
);
$template['default']['parser'] = 'parser';
$template['default']['parser_method'] = 'parse';
$template['default']['parse_template'] = FALSE;

And, when i want to render this template I do this in the controller:

Code:

$this->template->render();

But, for example, if i want another template for the backend, how can i do that?.
I want to do this in the controller:

Code:

$this->template->set_template('backend');
$this->template->render();

but i don't know what i have to do in the config/template.php

Can someone help me?
