810:
811: This module publishes a directory of files.
812:
813: This is part of the LearningOnline Network with CAPA project
814: described at http://www.lon-capa.org.

827:
828: start page output
829:
830: =item *
831:
832: run through list of files and attempt to publish unhidden files

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.
858:

860: $fullname - Fully qualified filename to check.
861:

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
880: - problem
881: - Other resource.
882:
883: For each file the modification date is determined as well.
884: Returned is a list of sublists:
885: (directories, sequences, problems, other)
886: each of the sublists contains entries of the following form (sorted by filename):
887: (filename, typecode, lastmodtime)
888:
889: $list = CategorizeFiles($location, $files)
890: $location - Directory in which the files live (relative to our execution)
891: $files - list of files.
