  41 =head1 NAME
  42
  43 C4::Breeding : module to add biblios to import_records via
  44                the breeding/reservoir API.
  45
  46 =head1 SYNOPSIS
  47
  48     use C4::Scan;
  49     &ImportBreeding($marcrecords,$overwrite_biblio,$filename,$z3950random,$batch_type);
  50
  51     C<$marcrecord> => the MARC::Record
  52     C<$overwrite_biblio> => if set to 1 a biblio with the same ISBN will be overwritted.
  53                                 if set to 0 a biblio with the same isbn will be ignored (the previous will be kept)
  54                                 if set to -1 the biblio will be added anyway (more than 1 biblio with the same ISBN
  55                                 possible in the breeding
  56     C<$encoding> => USMARC
  57                         or UNIMARC. used for char_decoding.
  58                         If not present, the parameter marcflavour is used instead
  59     C<$z3950random> => the random value created during a z3950 search result.
  60
  61 =head1 DESCRIPTION
  62
  63     ImportBreeding import MARC records in the reservoir (import_records/import_batches tables).
  64     the records can be properly encoded or not, we try to reencode them in utf-8 if needed.
  65     works perfectly with BNF server, that sends UNIMARC latin1 records. Should work with other servers too.

 223 Parameters for Z3950 search are all passed via the $pars hash. It may contain isbn, title, author, dewey, subject, lccall, controlnumber, stdid, srchany.
 224 Also it should contain an arrayref id that points to a list of id's of the z3950 targets to be queried (see z3950servers table).
 225 This code is used in acqui/z3950_search and cataloging/z3950_search.
 226 The second parameter $template is a Template object. The routine uses this parameter to store the found values into the template.
