|
|
Lint: L<Catmandu::Importer::MARC::Lint> - a MARC syntax checker |
167
|
|
|
|
|

If set, then any errors when parsing MARC input will be skipped and ignored. Use the |
175
|
|
|
|
|
|
|
debug setting of catmandu to view all error messages: |
176
|
|
|
|
|
|
|
|
177
|
|
|
|
|
|
|
$ catmandu -D convert MARC --skip_errors 1 < /foo/bar.mrc |
