|
| 124 |
update_unimarc_100a_language.pl |
| 125 |
|
| 126 |
=head1 SYNOPSIS |
| 127 |
|
| 128 |
Update all biblio records' field 100a language value with the one |
| 129 |
defined in the "UNIMARC field 100 default language" system preference. |
| 130 |
|
| 131 |
=head1 DESCRIPTION |
| 132 |
|
| 133 |
Due to bug 8347, Koha forced UNIMARC 100 field code language to 'fre' |
| 134 |
This script aims to replace the value on all the records, or in a |
| 135 |
given set of records, for a new value defined by the new system |
| 136 |
preference "UNIMARC field 100 default language". |
| 137 |
|
| 138 |
=head1 REQUIRED ARGUMENTS |
| 139 |
|
| 140 |
The script must be ran with B<one and only one> of these two options: -a or -b (-biblionumber) |
| 141 |
|
