  23 MARCdetail.pl : script to show a biblio in MARC format
  24
  25 =head1 SYNOPSIS
  26
  27 =cut
  28
  29 =head1 DESCRIPTION
  30
  31 This script needs a biblionumber as  parameter
  32
  33 It shows the biblio in a (nice) MARC format depending on MARC
  34 parameters tables.
  35
  36 The template is in <templates_dir>/catalogue/MARCdetail.tmpl.
  37 this template must be divided into 11 "tabs".
  38
  39 The first 10 tabs present the biblio, the 11th one presents
  40 the items attached to the biblio
