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

|
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
|

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
|

whether to permit this exception to apply to your modifications.
