 135 $0: establish relationship to host items
 136
 137 Based on barcode in host field populates subfield 0 with host biblionumber and subfield 9 with host itemnumber.
 138
 139 Subfield 0 and 9 are used in Koha screns to display relationships between analytical records and host bibs and items.
 140
 141 NOT usable with UNIMARC data. You can use it only if you have tag 461 with also an items id (like barcode or item numbers). In UNIMARC this situation is very rare. If you have data coded in this way, send a mail to koha-dev mailing list and ask for the feature.

 143 Parameters:
 144     --run-update            run the synchronization
 145     --where condition       selects the biblios on a criterium (Repeatable)
 146     --help or -h            show this message.
