The Jquery.fields.js plugin and the Draft module.

I'm a total newbie to Drupal, so please forgive in advance. I have Drupal 6 up and running, and I have installed several modules already, so I know how to do this part.

The proble: I want to install the "Draft" module, and the release notes say, "Module relies on the Jquery.fields.js plugin in order to save the form data."

However, I can't find a plugin named "Jquery.fields.js" anywhere in the Drupal modules DB. Where is it, and how do I install it if it's different than traditional Drupal modules.

Am I missing something?

Thanks in advance!
