/**
 * Attaches the batch behavior to progress bars.

  // This behavior attaches by ID, so is only valid once on a page.

    return;
  }
  $('#progress', context).addClass('batch-processed').each(function () {
    var holder = this;
    var uri = Drupal.settings.batch.uri;
    var initMessage = Drupal.settings.batch.initMessage;
    var errorMessage = Drupal.settings.batch.errorMessage;

    // Success: redirect to the summary.
