================

- Nothing changed yet.

==================

- Fix README; it was naming the csv-dialect option wrong.

================

- Added the ``--csv-dialect`` option so you can indicate the CSV
dialect to use.

- Added a ``europe`` dialect where the delimiter is ``;``, not
``,``. This to support Excel in Europe, as its CSV format is
locale-dependent. (why...)

================

- Initial public release.
