Text description for zone shipping methods

[choccybox]

Could somebody give me some idea as to what this text does in the zones.php file:

define('MODULE_SHIPPING_ZONES2_TEXT_DESCRIPTION', 'Text Here');

I can't seem to find anywhere on the website where this text appears.

Currently I have zones.php and zones2.php set up for two different shipping methods. What i'd like to do is add some text on the checkout shipping page below each option explaining each shipping method. How is that possible? I thought the above define would do it, but that text doesn't seem to appear anywhere.

Any help would be grateful!

That is used in the Admin on the right panel when the module is selected ...
