Koha::MarcModificationTemplates - Module to manage MARC Modification Templates |

|

=head1 DESCRIPTION |
| 64 |
|
| 65 |
MARC Modification Templates are a tool for marc batch imports, |
| 66 |
so that librarians can set up templates for various vendors' |
| 67 |
files telling Koha what fields to insert data into. |
