25 The exception is that, if you link a SANE library with other files
26 to produce an executable, this does not by itself cause the

28 License. Your use of that executable is in no way restricted on
29 account of linking the SANE library code into it.

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

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

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