As a special exception, the authors of SANE give permission for

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.

a subsequent release, you agree by submitting the changes that

those changes may be distributed with this exception intact.
