There is a new feature in WordPress 3.0 that allows to create some pretty cool menus. I'd like to know what to add to function.php and my header.php to get it to work.

When I add code to function.php, the Menus section does show in the Appearance subpanel, but I've been racking my brain all afternoon trying to get it to show up on the site.

Thanks for any help.
