920:
921: =over
922:
923: =item startpage($r, $uame, $udom, $thisdisfn)
924:
925: Output the header of the page. This includes:
926: - The HTML header
927: - The H1/H3 stuff which includes the directory.
928:
929: startpage($r, $uame, $udom, $thisdisfn);
930: $r - The apache request object.
931: $uname - User name.
932: $udom - Domain name the user is logged in under.
933: $thisdisfn - Displayable version of the filename.
934:
935: =item getTitleString($fullname)
936:
937: Get the title string or "[untitled]" if the file has no title metadata:
938: Without the latter substitution, it's impossible to examine metadata for
939: untitled resources. Resources may be legitimately untitled, to prevent
940: searches from locating them.
941:
942: $str = getTitleString($fullname);
943: $fullname - Fully qualified filename to check.
