  39 =head1 NAME
  40
  41 C4::Breeding : module to add biblios to import_records via
  42                the breeding/reservoir API.
  43
  44 =head1 SYNOPSIS
  45
  46     use C4::Scan;
  47     &ImportBreeding($marcrecords,$overwrite_biblio,$filename,$z3950random,$batch_type);
  48
  49     C<$marcrecord> => the MARC::Record
  50     C<$overwrite_biblio> => if set to 1 a biblio with the same ISBN will be overwritted.
  51                                 if set to 0 a biblio with the same isbn will be ignored (the previous will be kept)
  52                                 if set to -1 the biblio will be added anyway (more than 1 biblio with the same ISBN
  53                                 possible in the breeding
  54     C<$encoding> => USMARC
  55                         or UNIMARC. used for char_decoding.
  56                         If not present, the parameter marcflavour is used instead
  57     C<$z3950random> => the random value created during a z3950 search result.
  58
  59 =head1 DESCRIPTION
  60
  61     ImportBreeding import MARC records in the reservoir (import_records/import_batches tables).
  62     the records can be properly encoded or not, we try to reencode them in utf-8 if needed.
  63     works perfectly with BNF server, that sends UNIMARC latin1 records. Should work with other servers too.

 221 Parameters for Z3950 search are all passed via the $pars hash. It may contain isbn, title, author, dewey, subject, lccall, controlnumber, stdid, srchany.
 222 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).
 223 This code is used in acqui/z3950_search and cataloging/z3950_search.
 224 The second parameter $template is a Template object. The routine uses this parameter to store the found values into the template.
