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.

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
|
