974: =over
975:
976: =item startpage($r, $uame, $udom, $thisdisfn)
977:
978: Output the header of the page. This includes:
979: - The HTML header
980: - The H1/H3 stuff which includes the directory.
981:
982: startpage($r, $uame, $udom, $thisdisfn);
983: $r - The apache request object.
984: $uname - User name.
985: $udom - Domain name the user is logged in under.
986: $thisdisfn - Displayable version of the filename.
987:
988: =item getTitleString($fullname)
989:
990: Get the title string or "[untitled]" if the file has no title metadata:
991: Without the latter substitution, it's impossible to examine metadata for
992: untitled resources. Resources may be legitimately untitled, to prevent
993: searches from locating them.
994:
995: $str = getTitleString($fullname);
996: $fullname - Fully qualified filename to check.
