Multilingual Link to ToU in popup ?

Hello,

I've just read that readme.txt has an explanation in order to make ToU appear in a popup by pasting this code in template.php:

<?php
function THEMENAME_terms_of_use($terms, $node) {
$output = '<div id="terms-of-use" class="content clear-block">';
$output .= t('Terms of use of this page are available !here.', array('!here' => l('here', 'node/'."$node->nid")));
$output .= '</div>';
return $output;
}
?>

As far as I know this means that there will be a text which says "Terms of use of this page are available..." and I would like this text to be translatable, since my site is a multilingual site.

Regards
