the user whether he wants to recover the lost data or not. The user has the
possibility to view the differences between the original file and the recovered
one, too. The swap file is deleted after every save and on normal exit.</para>

have changed since the last sync. The user can disable the swap files syncing if
he wants, by checking the <guilabel>Disable swap file syncing</guilabel> box,
