=head1 NAME
C4::Breeding : script to add a biblio in marc_breeding table.
=head1 SYNOPSIS
use C4::Scan;
&ImportBreeding($marcrecords,$overwrite_biblio,$filename,$z3950random);
C<$marcrecord> => the MARC::Record
C<$overwrite_biblio> => if set to 1 a biblio with the same ISBN will be overwritted.
if set to 0 a biblio with the same isbn will be ignored (the previous will be kept)
if set to -1 the biblio will be added anyway (more than 1 biblio with the same ISBN possible in the breeding
C<$encoding> => USMARC
or UNIMARC. used for char_decoding.
If not present, the parameter marcflavour is used instead
C<$z3950random> => the random value created during a z3950 search result.
=head1 DESCRIPTION
This module doesn't do anything.
