+
+=head1 INTRODUCTION
+
+This module publishes a directory of files.
+
+This is part of the LearningOnline Network with CAPA project
+described at http://www.lon-capa.org.
+
+=head1 HANDLER SUBROUTINE
+
+This routine is called by Apache and mod_perl.
+
+=over 4
+
+=item *
+
+read in information
+
+=item *
+
+start page output
+
+=item *
+
+run through list of files and attempt to publish unhidden files
+
+=back
+
+=head2 OTHER SUBROUTINES:
+
+=head3 startpage($r, $uame, $udom, $thisdisfn)
+
+Output the header of the page. This includes:
+ - The HTML header
+ - The H1/H3 stuff which includes the directory.
+
+ startpage($r, $uame, $udom, $thisdisfn);
+ $r - The apache request object.
+ $uname - User name.
+ $udom - Domain name the user is logged in under.
+ $thisdisfn - Displayable version of the filename.
+
+=head3 getTitleString($fullname)
+
+ Get the title string or "[untitled]" if the file has no title metadata:
+ Without the latter substitution, it's impossible to examine metadata for
+ untitled resources. Resources may be legitimately untitled, to prevent
+ searches from locating them.
+
+ $str = getTitleString($fullname);
+ $fullname - Fully qualified filename to check.
+
+=head3 putdirectory(r, base, here, dirname, modtime)
+
+ Put out a directory table row:
+
+ putdirectory($r, $base, $here, $dirname, $modtime)
+ $r - Apache request object.
+ $reqfile - File in request.
+ $here - Where we are in directory tree.
+ $dirname - Name of directory special file.
+ $modtime - Encoded modification time.
+
+=head3 CategorizeFiles($location, $files)
+
+ Categorize files in the directory.
+ For each file in a list of files in a file directory,
+ the file categorized as one of:
+ - directory
+ - sequence
+ - problem
+ - Other resource.
+
+ For each file the modification date is determined as well.
+ Returned is a list of sublists:
+ (directories, sequences, problems, other)
+ each of the sublists contains entries of the following form (sorted by filename):
+ (filename, typecode, lastmodtime)
+
+ $list = CategorizeFiles($location, $files)
+ $location - Directory in which the files live (relative to our execution)
+ $files - list of files.
