=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
=head1 SUBROUTINES:
=over
=item 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.
$thisdisfn - Displayable version of the filename.
=item getTitleString($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);
$fullname - Fully qualified filename to check.
=item putdirectory($r, $base, $here, $dirname, $modtime, $targetdir, $bombs,
$numdir)
Put out a directory table row:
$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.
targetdir - Publication target directory.
bombs - Reference to hash of URLs with runtime error messages.
numdir - Reference to scalar used to track number of sub-directories
in directory (used in form name for each "actions" dropdown).
