+
+   If you submit changes to SANE to the maintainers to be included in
+   a subsequent release, you agree by submitting the changes that

+   If you write modifications of your own for SANE, it is your choice
+   whether to permit this exception to apply to your modifications.

+
+   This file implements a SANE backend for scanners based on the Mustek
+   MA-1509 chipset. Currently the Mustek BearPaw 1200F is known to work.
