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
