Convert to Drupal 6

Hi Chris,

I like the idea of the module. I try the convert the first part of the "menu part" into Vers. 6, but i'm not good enough to do this with the whole thing. Are you able to transform it?

Cheers Kai

My part:
/**
* Implementation of hook_menu().
*/
function public_preview_menu() {
$items = array();
if ($may_cache) {

$items['admin/content/preview'] = array(
'title' => 'Content Preview',
'description' => 'Settings to allow users access to unpublished content.',
'page callback' => 'drupal_get_form',
'page arguments' => array('public_preview_admin_settings', 2),
// NOTE: as of Drupal 6.2, all menu items are *required* to have
// access control.
'access arguments' => array('administer site configuration'),
'type' => MENU_LOCAL_ITEM,
);
} else {
.....
