899: =over
900:
901: =item startpage($r, $uame, $udom, $thisdisfn)
902:
903: Output the header of the page. This includes:
904: - The HTML header
905: - The H1/H3 stuff which includes the directory.
906:
907: startpage($r, $uame, $udom, $thisdisfn);
908: $r - The apache request object.
909: $uname - User name.
910: $udom - Domain name the user is logged in under.
911: $thisdisfn - Displayable version of the filename.
912:
913: =item getTitleString($fullname)
914:
915: Get the title string or "[untitled]" if the file has no title metadata:
916: Without the latter substitution, it's impossible to examine metadata for
917: untitled resources. Resources may be legitimately untitled, to prevent
918: searches from locating them.
919:
920: $str = getTitleString($fullname);
921: $fullname - Fully qualified filename to check.
