Please note that field numbers are consistent with other commands (marc |

field number first), but somewhat counter-intuitive (destination and then |
657 |

source). |

You might want to use this command if you are just renaming subfields or |
660 |
|
using pre-processing modify_record in C<config.yml> and don't need any |
661 |
|
post-processing or want to preserve order of original subfields. |
