   =head1 NAME
   
   lonpublisher - LON-CAPA publishing handler
   
   =head1 SYNOPSIS
   
   B<lonpublisher> is used by B<mod_perl> inside B<Apache>.  This is the
   invocation by F<loncapa_apache.conf>:
   
     <Location /adm/publish>
     PerlAccessHandler       Apache::lonacc
     SetHandler perl-script
     PerlHandler Apache::lonpublisher
     ErrorDocument     403 /adm/login
     ErrorDocument     404 /adm/notfound.html
     ErrorDocument     406 /adm/unauthorized.html
     ErrorDocument     500 /adm/errorhandler
     </Location>
   
   =head1 DESCRIPTION
   
   B<lonpublisher> takes the proper steps to add resources to the LON-CAPA
   digital library.  This includes updating the metadata table in the
   LON-CAPA database.
   
   B<lonpublisher> is many things to many people.  
   
   This module publishes a file.  This involves gathering metadata,
   versioning the file, copying file from construction space to
   publication space, and copying metadata from construction space
   to publication space.
   
   =head2 SUBROUTINES
   
   Many of the undocumented subroutines implement various magical
   parsing shortcuts.

 This module publishes a file.  This involves gathering metadata,  
 versioning the file, copying file from construction space to  
 publication space, and copying metadata from construction space  
 to publication space.  
   
 This is part of the LearningOnline Network with CAPA project  
 described at http://www.lon-capa.org.
