Implement in framework

Hi there,

My framework has a (for me) complex code. Anybody know how to implement the wp-paginate code?
:

function xtreme_post_pagination() {
	global $wp_query;
	$options = get_option( XF_OPTIONS );
    $start = '<div class="pagination">';
    $end = '</div>';
    if ( xtreme_is_html5() ) {
        $start = '<nav class="pagination">';
        $end = '</nav>';
    }
    echo $start;
	if (!isset($options['xc_pagination']) || $options['xc_pagination']['pagination_type']['value'] != 1) : ?>
    <div class="previous_link"><?php previous_posts_link(__('Newer Posts <span>→</span>', XF_TEXTDOMAIN)) ?></div>
    <div class="next_link"><?php next_posts_link(__('<span>←</span> Older Posts', XF_TEXTDOMAIN)) ?></div>
    <?php else: ?>
	<?php
		$type = (isset($options['xc_pagination']['type']['value']) ? $options['xc_pagination']['type']['value'] : 'plain');
		$big = 999999999; // need an unlikely integer
		$page_links = paginate_links( array(
			'base' => str_replace( $big, '%#%', get_pagenum_link( $big ) ),
			'format' => '?paged=%#%',
			'current' => max( 1, get_query_var('paged') ),
			'total' => $wp_query->max_num_pages,
			'end_size' => (isset($options['xc_pagination']['end_size']['value']) ? (int)$options['xc_pagination']['end_size']['value'] : 1),
			'mid_size' => (isset($options['xc_pagination']['mid_size']['value']) ? (int)$options['xc_pagination']['mid_size']['value'] : 2),
			'show_all' => (isset($options['xc_pagination']['show_all']['value']) ? (bool)$options['xc_pagination']['show_all']['value'] : false),
			'prev_next' => (isset($options['xc_pagination']['prev_next']['value']) ? (bool)$options['xc_pagination']['prev_next']['value']: true),
			'type' => 'array'
		) );
		$page_links = apply_filters( 'xtreme_post_pagination', $page_links);
		if (is_array($page_links)) {
			switch($type) {
				case 'list':
					$r .= "<ul class='page-numbers'>\n\t<li>";
					$r .= join("</li>\n\t<li>", $page_links);
					$r .= "</li>\n</ul>\n";
					break;
				default:
					$r = join("\n", $page_links);
					break;
			}
		}else $r = (string)$page_links;
		echo $r;
	?>
	<?php endif;
	echo $end;
}

Jasper.
