786:
787: =over
788:
789: =item startpage($r, $uame, $udom, $thisdisfn)
790:
791: Output the header of the page. This includes:
792: - The HTML header
793: - The H1/H3 stuff which includes the directory.
794:
795: startpage($r, $uame, $udom, $thisdisfn);

797: $uname - User name.
798: $udom - Domain name the user is logged in under.
799: $thisdisfn - Displayable version of the filename.
800:
801: =item getTitleString($fullname)
802:
803: Get the title string or "[untitled]" if the file has no title metadata:
804: Without the latter substitution, it's impossible to examine metadata for
805: untitled resources. Resources may be legitimately untitled, to prevent
806: searches from locating them.

814:
815: putdirectory($r, $base, $here, $dirname, $modtime)
816: $r - Apache request object.
817: $reqfile - File in request.
818: $here - Where we are in directory tree.
819: $dirname - Name of directory special file.
820: $modtime - Encoded modification time.
821:
822: =item CategorizeFiles($location, $files)
823:
824: Categorize files in the directory.
825: For each file in a list of files in a file directory,
826: the file categorized as one of:
827: - directory
828: - sequence
829: - problem
830: - Other resource.
831:
832: For each file the modification date is determined as well.
833: Returned is a list of sublists:
834: (directories, sequences, problems, other)
835: each of the sublists contains entries of the following form (sorted by filename):
836: (filename, typecode, lastmodtime)
837:
838: $list = CategorizeFiles($location, $files)
839: $location - Directory in which the files live (relative to our execution)
