902: =over
903:
904: =item startpage($r, $uame, $udom, $thisdisfn)
905:
906: Output the header of the page. This includes:
907: - The HTML header
908: - The H1/H3 stuff which includes the directory.

911: $r - The apache request object.
912: $uname - User name.
913: $udom - Domain name the user is logged in under.
914: $thisdisfn - Displayable version of the filename.
915:
916: =item getTitleString($fullname)
917:
918: Get the title string or "[untitled]" if the file has no title metadata:
919: Without the latter substitution, it's impossible to examine metadata for
920: untitled resources. Resources may be legitimately untitled, to prevent
921: searches from locating them.
922:
923: $str = getTitleString($fullname);
924: $fullname - Fully qualified filename to check.
