 * Uses drupal_execute() to programmatically create node translations when cron runs.
 * Based on code from http://drupal.org/node/131704, http://drupal.org/node/293663, 
 * and my own Amazon node import script (http://drupal.org/node/231612, comment #14).
 * See http://www.lullabot.com/articles/quick_and_dirty_cck_imports for general technique.
