Custom Configuration File For Application

[eluser]carvingCode[/eluser]
The statements for part of the settings of the Pagination library. Instead of including them, as listed below, I thought I could place them in a app config file and just call an array. Is this where a 'hook' may come in handy?

Code:

$config['first_tag_open'] = ' | ';
$config['first_tag_close'] = ' |';
$config['last_tag_open'] = '| ';
$config['last_tag_close'] = '| ';
$config['num_tag_open'] = ' | ';
$config['next_tag_open'] = ' | ';
$config['next_tag_close'] = ' ';
