Drupal 7 add Synonyms to Core Taxonomy

In my Drupal 7 Taxonomy Reinvented post I mentioned that the synonyms option for terms are removed in Drupal 7.

When searching for some other features I stumbled on the Synonyms module at drupal.org. This module does not only add back the option, but also integrates with the search module as well as making it easier to find related nodes.

I haven't tested it yet since I don't need this functionality for any of my projects (yet), but I thought I would mention it if you are looking for this functionality.

The module is also available for Drupal 5 and 6, except the part about adding back the synonym field.
