296<p>A record is read from the input-source-file and the data is checked. If the
297record can be imported, it is <strong>appended</strong> to the file XXX_imported.csv,
298otherwise it is <strong>inserted</strong> into the file XXX_pending.csv, if no record
299with the exact same date already exists in the XXX_pending.csv. The check is
300done by comparing the md5-digests of the new record with the existing records.</p>
301<p>When doing the import in pending-only-mode the XXX_pending.csv is taken as
302input-source-file and if a record can now be imported it is appended to the
303XXX_imported.csv file and removed from XXX_pending.csv.</p>
304<p><strong>Caveat</strong>:</p>
305<blockquote>
306if an record is inserted into XXX_pending, it will only be removed by
307importing in pending-only-mode. If a new input-file contains a record for
308the same object, with different data, that will not be detected at the
309moment.</blockquote>
