* Default file-based {@link DocumentConverter} implementation.

* This implementation passes document data to and from the OpenOffice.org
* service as file URLs.
* <p>
* File-based conversions are faster than stream-based ones (provided by
* {@link StreamOpenOfficeDocumentConverter}) but they require the
* OpenOffice.org service to be running locally and have the correct
* permissions to the files.
