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

additional uses of the libraries contained in this release of SANE.

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

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.

This exception does not, however, invalidate any other reasons why

the executable file might be covered by the GNU General Public

License.

If you submit changes to SANE to the maintainers to be included in

a subsequent release, you agree by submitting the changes that

those changes may be distributed with this exception intact.

If you write modifications of your own for SANE, it is your choice
