19 As a special exception, the authors of SANE give permission for
20 additional uses of the libraries contained in this release of SANE.

22 The exception is that, if you link a SANE library with other files
23 to produce an executable, this does not by itself cause the
24 resulting executable to be covered by the GNU General Public
25 License. Your use of that executable is in no way restricted on
26 account of linking the SANE library code into it.

28 This exception does not, however, invalidate any other reasons why
29 the executable file might be covered by the GNU General Public
30 License.

32 If you submit changes to SANE to the maintainers to be included in
33 a subsequent release, you agree by submitting the changes that
34 those changes may be distributed with this exception intact.
35
36 If you write modifications of your own for SANE, it is your choice
37 whether to permit this exception to apply to your modifications.
