    As a special exception, the authors of SANE give permission for
    additional uses of the libraries contained in this release of SANE.

    The exception is that, if you link a SANE library with other files
    to produce an executable, this does not by itself cause the
    resulting executable to be covered by the GNU General Public
    License.  Your use of that executable is in no way restricted on
    account of linking the SANE library code into it.

    This exception does not, however, invalidate any other reasons why
    the executable file might be covered by the GNU General Public
    License.
-

    If you submit changes to SANE to the maintainers to be included in
    a subsequent release, you agree by submitting the changes that
    those changes may be distributed with this exception intact.

    If you write modifications of your own for SANE, it is your choice
    whether to permit this exception to apply to your modifications.
