900: =head1 HANDLER SUBROUTINE
901:
902: This routine is called by Apache and mod_perl.

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