18    As a special exception, the authors of SANE give permission for
19    additional uses of the libraries contained in this release of SANE.
20 
21    The exception is that, if you link a SANE library with other files
22    to produce an executable, this does not by itself cause the
23    resulting executable to be covered by the GNU General Public
24    License.  Your use of that executable is in no way restricted on
25    account of linking the SANE library code into it.
26 
27    This exception does not, however, invalidate any other reasons why
28    the executable file might be covered by the GNU General Public
29    License.
30 
31    If you submit changes to SANE to the maintainers to be included in
32    a subsequent release, you agree by submitting the changes that
33    those changes may be distributed with this exception intact.
34 
35    If you write modifications of your own for SANE, it is your choice
36    whether to permit this exception to apply to your modifications.
