25 account of linking the SANE library code into it.

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.
