=head1 NAME

MARCdetail.pl : script to show a biblio in MARC format

=head1 SYNOPSIS


=head1 DESCRIPTION

This script needs a biblionumber in bib parameter (bibnumber
from koha style DB.  Automaticaly maps to marc biblionumber).

It shows the biblio in a (nice) MARC format depending on MARC
parameters tables.

The template is in <templates_dir>/catalogue/MARCdetail.tmpl.
this template must be divided into 11 "tabs".

The first 10 tabs present the biblio, the 11th one presents
the items attached to the biblio
