  25 opac-MARCdetail.pl : script to show a biblio in MARC format
  26
  27 =head1 SYNOPSIS
  28
  29 =cut

  31 =head1 DESCRIPTION
  32
  33 This script needs a biblionumber as  parameter
  34
  35 It shows the biblio in a (nice) MARC format depending on MARC
  36 parameters tables.
  37
  38 The template is in <templates_dir>/catalogue/MARCdetail.tt.
  39 this template must be divided into 11 "tabs".
  40
  41 The first 10 tabs present the biblio, the 11th one presents
  42 the items attached to the biblio
