=head1 NAME

nl-search.pl - Script for searching the Norwegian national patron database

=head1 DESCRIPTION

This script will search the Norwegian national patron database, and let staff
import patrons from the natial database into the local database.

In order to use this, a username/password from the Norwegian national database
of libraries ("Base Bibliotek") is needed. A special key is also needed, in
order to decrypt and encrypt PIN-codes/passwords.

See http://www.lanekortet.no/ for more information (in Norwegian).
