The "sitemap-extra" setting:

The sitemap-extra setting defines extra links to appear on the /sitemap web page as sub-items of the "Home Page" entry before the "Documentation Search" entry (if any). For skins that use the /sitemap page to construct a hamburger menu dropdown, new entries added here will appear on the hamburger menu.

This setting should be a TCL list divided into triples. Each triple defines a new entry:

• The first term is the display name of the /sitemap entry

• The second term is a hyperlink to take when a user clicks on the entry. Hyperlinks that start with "/" are relative to the repository root.

• The third term is an argument to the TH1 "capexpr" command. If capexpr evaluates to true, then the entry is shown. If not, the entry is omitted. "*" is always true.

The default value is blank, meaning no added entries.
