21   The exception is that, if you link a SANE library with other files

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.

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.

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.
