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

862: =head1 SUBROUTINES:
863:
864: =over
865:
866: =item startpage($r, $uame, $udom, $thisdisfn)
867:
868: Output the header of the page. This includes:
869: - The HTML header
870: - The H1/H3 stuff which includes the directory.
871:
872: startpage($r, $uame, $udom, $thisdisfn);
873: $r - The apache request object.
874: $uname - User name.
875: $udom - Domain name the user is logged in under.
876: $thisdisfn - Displayable version of the filename.
877:
878: =item getTitleString($fullname)
879:
880: Get the title string or "[untitled]" if the file has no title metadata:
881: Without the latter substitution, it's impossible to examine metadata for
882: untitled resources. Resources may be legitimately untitled, to prevent
883: searches from locating them.

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