20    As a special exception, the authors of SANE give permission for
21    additional uses of the libraries contained in this release of SANE.
22 
23    The exception is that, if you link a SANE library with other files
24    to produce an executable, this does not by itself cause the
25    resulting executable to be covered by the GNU General Public
26    License.  Your use of that executable is in no way restricted on
27    account of linking the SANE library code into it.

29    This exception does not, however, invalidate any other reasons why
30    the executable file might be covered by the GNU General Public
31    License.
32 
33    If you submit changes to SANE to the maintainers to be included in
34    a subsequent release, you agree by submitting the changes that
35    those changes may be distributed with this exception intact.
36 
37    If you write modifications of your own for SANE, it is your choice
38    whether to permit this exception to apply to your modifications.
