+@extra_breadcrumbs::
+ Additional links to be added to the start of the breadcrumb trail before
+ the home link, to pages that are logically "above" the gitweb projects
+ list, such as the organization and department which host the gitweb
+ server. Each element of the list is a reference to an array, in which
+ element 0 is the link text (equivalent to `$home_link_str`) and element
+ 1 is the target URL (equivalent to `$home_link`).
++
+For example, the following setting produces a breadcrumb trail like
+"home / dev / projects / ..." where "projects" is the home link.
