                     67: =head1 OVERVIEW
                     68: 
                     69: Authors can only write-access the C</~authorname/> space. They can
                     70: copy resources into the resource area through the publication step,
                     71: and move them back through a recover step. Authors do not have direct
                     72: 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.

                     87: =head1 DESCRIPTION
                     88: 
                     89: B<lonpublisher> takes the proper steps to add resources to the LON-CAPA
1.90      matthew    90: digital library.  This includes updating the metadata table in the
                     91: LON-CAPA database.
                     92: 
1.94      harris41   93: B<lonpublisher> is many things to many people.  
1.90      matthew    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: 
1.94      harris41  100: =head2 SUBROUTINES
                    101: 
                    102: Many of the undocumented subroutines implement various magical
                    103: parsing shortcuts.
