   48: =head1 NAME
   49: 
   50: lonpublisher - LON-CAPA publishing handler
   51: 
   52: =head1 SYNOPSIS
   53: 
   54: B<lonpublisher> is used by B<mod_perl> inside B<Apache>.  This is the
   55: invocation by F<loncapa_apache.conf>:
   56: 
   57:   <Location /adm/publish>
   58:   PerlAccessHandler       Apache::lonacc
   59:   SetHandler perl-script
   60:   PerlHandler Apache::lonpublisher
   61:   ErrorDocument     403 /adm/login
   62:   ErrorDocument     404 /adm/notfound.html
   63:   ErrorDocument     406 /adm/unauthorized.html
   64:   ErrorDocument     500 /adm/errorhandler
   65:   </Location>
   66: 
   67: =head1 OVERVIEW
   68: 
   69: Authors can only write-access the C</priv/domain/authorname/> space. 
   70: They can copy resources into the resource area through the 
   71: publication step, and move them back through a recover step. 
   72: Authors do not have direct write-access to their resource space.
   73: 
   74: During the publication step, several events will be
   75: triggered. Metadata is gathered, where a wizard manages default
   76: entries on a hierarchical per-directory base: The wizard imports the
   77: metadata (including access privileges and royalty information) from
   78: the most recent published resource in the current directory, and if
   79: that is not available, from the next directory above, etc. The Network
   80: keeps all previous versions of a resource and makes them available by
   81: an explicit version number, which is inserted between the file name
   82: and extension, for example C<foo.2.html>, while the most recent
   83: version does not carry a version number (C<foo.html>). Servers
   84: subscribing to a changed resource are notified that a new version is
   85: available.
   86: 
   87: =head1 DESCRIPTION
   88: 
   89: B<lonpublisher> takes the proper steps to add resources to the LON-CAPA
   90: digital library.  This includes updating the metadata table in the
   91: LON-CAPA database.
   92: 
   93: B<lonpublisher> is many things to many people.  
   94: 
   95: This module publishes a file.  This involves gathering metadata,
   96: versioning the file, copying file from construction space to
   97: publication space, and copying metadata from construction space
   98: to publication space.
   99: 
  100: =head2 SUBROUTINES
  101: 
  102: Many of the undocumented subroutines implement various magical
  103: parsing shortcuts.
