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