It allows one php file to output more than one template according to the address bar.

PHP Code:

// file.php?do=eggnog
if ($_REQUEST['do'] == 'eggnog')
{
    // Outputs the eggnog template
    eval('print_output("' . fetch_template('eggnog') . '");');
}

// file.php?do=vbulletin
elseif ($_REQUEST['do'] == 'vbulletin')
{
    // Outputs the vbulletin template
    eval('print_output("' . fetch_template('vbulletin') . '");');
}
