Code

function purr_messages_help($path, $arg) {
  if ($path == 'admin/settings/purr') {
    if (module_exists('libraries')) {
      if (!file_exists(libraries_get_path('jquery_purr/jquery.purr.js'))) {

          You need to download the Purr jquery file from
          <a href="http://jquery-purr.googlecode.com/files/jquery-purr0-1-0.zip">
          http://jquery-purr.googlecode.com/files/jquery-purr0-1-0.zip</a>.<br/>
          Decompress it and put just the jquery.purr.js file inside a directory
          called jquery_purr in your !libraries path. For example the final path
          could be: /sites/all/libraries/jquery_purr/jquery.purr.js', array(
          '!libraries' => l('Libraries', 'http://drupal.org/project/libraries'),
        ));

      else {
        return t('<strong>jQuery file status:</strong> The jquery file is in place.');
      }
    }
    else {
      return t('You must install the <a href="http://drupal.org/project/libraries">Libraries API</a>');
