783:
784: =over
785:
786: =item startpage($r, $uame, $udom, $thisdisfn)
787:
788: Output the header of the page. This includes:
789: - The HTML header
790: - The H1/H3 stuff which includes the directory.
791:
792: startpage($r, $uame, $udom, $thisdisfn);
793: $r - The apache request object.
794: $uname - User name.
795: $udom - Domain name the user is logged in under.
796: $thisdisfn - Displayable version of the filename.
797:
798: =item getTitleString($fullname)
799:
800: Get the title string or "[untitled]" if the file has no title metadata:
801: Without the latter substitution, it's impossible to examine metadata for
802: untitled resources. Resources may be legitimately untitled, to prevent
803: searches from locating them.

809:
810: Put out a directory table row:
811:
812: putdirectory($r, $base, $here, $dirname, $modtime)
813: $r - Apache request object.
814: $reqfile - File in request.
815: $here - Where we are in directory tree.
816: $dirname - Name of directory special file.
817: $modtime - Encoded modification time.
818:
819: =item CategorizeFiles($location, $files)
820:
821: Categorize files in the directory.
822: For each file in a list of files in a file directory,
823: the file categorized as one of:
824: - directory
825: - sequence
826: - problem
827: - Other resource.
828:
829: For each file the modification date is determined as well.
830: Returned is a list of sublists:
831: (directories, sequences, problems, other)
832: each of the sublists contains entries of the following form (sorted by filename):
833: (filename, typecode, lastmodtime)
834:
835: $list = CategorizeFiles($location, $files)
836: $location - Directory in which the files live (relative to our execution)
