835:
836: This module publishes a directory of files.

862:
863: =over
864:
865: =item startpage($r, $uame, $udom, $thisdisfn)
866:

868: - The HTML header
869: - The H1/H3 stuff which includes the directory.
870:
871: startpage($r, $uame, $udom, $thisdisfn);

874: $udom - Domain name the user is logged in under.
875: $thisdisfn - Displayable version of the filename.
876:
877: =item getTitleString($fullname)
878:
879: Get the title string or "[untitled]" if the file has no title metadata:
880: Without the latter substitution, it's impossible to examine metadata for
881: untitled resources. Resources may be legitimately untitled, to prevent

892: $r - Apache request object.
893: $reqfile - File in request.

895: $dirname - Name of directory special file.
896: $modtime - Encoded modification time.
897:
898: =item CategorizeFiles($location, $files)
899:
900: Categorize files in the directory.
901: For each file in a list of files in a file directory,
902: the file categorized as one of:
903: - directory
904: - sequence
905: - problem
906: - Other resource.
907:
908: For each file the modification date is determined as well.
909: Returned is a list of sublists:
910: (directories, sequences, problems, other)
911: each of the sublists contains entries of the following form (sorted by filename):
912: (filename, typecode, lastmodtime)
913:
914: $list = CategorizeFiles($location, $files)
915: $location - Directory in which the files live (relative to our execution)
