1388 If $mergeto is missing, the biblio field is deleted.
1389
1390 MARCfrom is used to determine if a cleared subfield in the authority record
1391 should be removed from a biblio. MARCto is used to populate the biblio
1392 record with the updated values; if you do not pass it, the biblio field
1393 will be deleted (same as missing mergeto).

1395 Normally all biblio records linked to $mergefrom, will be considered. But
1396 you can pass specific numbers via the biblionumbers parameter.
1397
1398 The parameter override_limit is used by the cron job to force larger
1399 postponed merges.
