896: =over
897:
898: =item startpage($r, $uame, $udom, $thisdisfn)
899:
900: Output the header of the page. This includes:
901: - The HTML header
902: - The H1/H3 stuff which includes the directory.

905: $r - The apache request object.
906: $uname - User name.
907: $udom - Domain name the user is logged in under.
908: $thisdisfn - Displayable version of the filename.
909:
910: =item getTitleString($fullname)
911:
912: Get the title string or "[untitled]" if the file has no title metadata:
913: Without the latter substitution, it's impossible to examine metadata for
914: untitled resources. Resources may be legitimately untitled, to prevent
915: searches from locating them.
916:
917: $str = getTitleString($fullname);
918: $fullname - Fully qualified filename to check.
