A little help needed with creating a library

[eluser]darkhouse[/eluser]
I don't see anything wrong off hand with your code. My config files load automatically. Here's some sample working code from my External library.

Code:

class CI_External {
    
    var $CI;

    function CI_External($groups = array()){    
        $this->CI =& get_instance();
        
        if(is_array($groups) && count($groups) > 0){
            //parse groups
        }
    }
    
    //...etc
}

And here's my config file...

Code:

$config = array(
    'all' => array(
        'css' => array(
            'css/reset.css',
            'css/shortcuts.css',
            array('.png_bg {behavior: url(iepngfix.htc)}', 'ie6_custom')
        ),
        'js' => array(
            'js/functions.js',
            array('var base_url = "'.base_url().'";', 'custom'),
            array('js/ie_png_fix.js', 'ie6')    
        )
    ),
    'default' => array('css' => 'css/master.css'),
    'admin' => array('css' => 'css/admin/master.css'),
    'beta' => array('css' => array('css/beta.css', 'css/960.css'))
);
