Add language handling functionality and enables the translation of the user interface to languages other than English.

Code

function locale_block($op = 'list', $delta = 0) {
  if ($op == 'list') {
    $block[0]['info'] = t('Language switcher');
    // Not worth caching.
    $block[0]['cache'] = BLOCK_NO_CACHE;
    return $block;
  }

  // Only show if we have at least two languages and language dependent
  // web addresses, so we can actually link to other language versions.
  elseif ($op == 'view' && variable_get('language_count', 1) > 1 && variable_get('language_negotiation', LANGUAGE_NEGOTIATION_NONE) != LANGUAGE_NEGOTIATION_NONE) {
    $path = drupal_is_front_page() ? '<front>' : $_GET['q'];
    $languages = language_list('enabled');
    $links = array();
    foreach ($languages[1] as $language) {
      $links[$language->language] = array(
        'href' => $path,
        'title' => $language->native,
        'language' => $language,
        'attributes' => array('class' => 'language-link'),
      );
    }

    // Allow modules to provide translations for specific links.
    // A translation link may need to point to a different path or use
    // a translated link text before going through l(), which will just
    // handle the path aliases.
    drupal_alter('translation_link', $links, $path);

    $block['subject'] = t('Languages');
