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