The navigational links are the same as in Section 6.5, “buildEmptyPage(): Set up an empty page”. Only the generic page title is different.

We set up a generic page title at this point because the desired page title will display the name of the selected region—but that comes from the CGI arguments, and we haven't even looked at those yet. Fortunately, the TCCPage class allows the titles to be changed after page creation.
