                     85: =head1 OVERVIEW
                     86: 
                     87: Authors can only write-access the C</~authorname/> space. They can
                     88: copy resources into the resource area through the publication step,
                     89: and move them back through a recover step. Authors do not have direct
                     90: write-access to their resource space.
                     91: 
                     92: During the publication step, several events will be
                     93: triggered. Metadata is gathered, where a wizard manages default
                     94: entries on a hierarchical per-directory base: The wizard imports the
                     95: metadata (including access privileges and royalty information) from
                     96: the most recent published resource in the current directory, and if
                     97: that is not available, from the next directory above, etc. The Network
                     98: keeps all previous versions of a resource and makes them available by
                     99: an explicit version number, which is inserted between the file name
                    100: and extension, for example C<foo.2.html>, while the most recent
                    101: version does not carry a version number (C<foo.html>). Servers
                    102: subscribing to a changed resource are notified that a new version is
                    103: available.

                    105: =head1 DESCRIPTION
                    106: 
                    107: B<lonpublisher> takes the proper steps to add resources to the LON-CAPA
1.90      matthew   108: digital library.  This includes updating the metadata table in the
                    109: LON-CAPA database.
                    110: 
1.94      harris41  111: B<lonpublisher> is many things to many people.  
1.90      matthew   112: 
                    113: This module publishes a file.  This involves gathering metadata,
                    114: versioning the file, copying file from construction space to
                    115: publication space, and copying metadata from construction space
                    116: to publication space.
                    117: 
1.94      harris41  118: =head2 SUBROUTINES
                    119: 
                    120: Many of the undocumented subroutines implement various magical
                    121: parsing shortcuts.
