Where do I enter the "Google™ Analytics Code"?

There is a new GA code (September 2010); http://www.google.com/support/analytics/bin/answer.py?answer=174090

The code needs to be entered in the source code of the page. The best way to integrate the new GA code is to use a Design Attribute in the Design Module "htmlHead" or to include it directly in the "htmlHead" , either way before </head>. (Formerly the code was placed at the end of the page).
