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
|
|
whether to permit this exception to apply to your modifications.
|
|
If you do not wish that, delete this exception notice.
