 =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.

 This routine is called by Apache and mod_perl.

 =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.
