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