=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.

=item B<metaeval>
Evaluates a string that contains metadata. This subroutine
stores values inside I<%metadatafields> and I<%metadatakeys>.
The hash key is a I<$unikey> corresponding to a unique id
that is descriptive of the parser location inside the XML tree.
Parameters:
=over 4
=item I<$metastring>
A string that contains metadata.

Returns:
nothing

This is the workhorse function of this module. This subroutine generates
backup copies, performs any automatic processing (prior to publication,
especially for rat and ssi files),
Returns a 2 element array, the first is the string to be shown to the
user, the second is an error code, either 1 (an error occured) or 0
(no error occurred)
