[jQuery] Download

I downloaded what I believe is the minified production version, it
shows up on the download page as jquery-1.3.2.min.js but when I
download it it is  jquery-1.3.2.min.download I tried running this (is
is some kind of self unpacking file format?  doesn't seem to be).  I
tried renaming it to .js, but as near as I can tell in attempting to
use it with the tutorial, it doesn't seem to be getting me anywhere.

Any thoughts?  (I think I need the pre-beginner tutorial)
