836: =head1 SUBROUTINES:
837:
838: =over
839:
840: =item startpage($r, $uame, $udom, $thisdisfn)
841:
842: Output the header of the page. This includes:
843: - The HTML header
844: - The H1/H3 stuff which includes the directory.
845:
846: startpage($r, $uame, $udom, $thisdisfn);
847: $r - The apache request object.
848: $uname - User name.
849: $udom - Domain name the user is logged in under.
850: $thisdisfn - Displayable version of the filename.
851:
852: =item getTitleString($fullname)
853:
854: Get the title string or "[untitled]" if the file has no title metadata:
855: Without the latter substitution, it's impossible to examine metadata for
856: untitled resources. Resources may be legitimately untitled, to prevent
857: searches from locating them.

863:
864: Put out a directory table row:
865:
866: putdirectory($r, $base, $here, $dirname, $modtime)
867: $r - Apache request object.
868: $reqfile - File in request.
869: $here - Where we are in directory tree.
870: $dirname - Name of directory special file.
871: $modtime - Encoded modification time.
872:
873: =item CategorizeFiles($location, $files)
874:
875: Categorize files in the directory.
876: For each file in a list of files in a file directory,
877: the file categorized as one of:
878: - directory
879: - sequence
