Copyright (C) 1998 David Huggins-Daines, heavily based on the Apple
|

|
scanner driver (since Abaton scanners are very similar to old Apple
|
||
|
scanners), which is (C) 1998 Milon Firikis, which is, in turn, based
|
||
|
on the Mustek driver, (C) 1996-7 David Mosberger-Tang.

As a special exception, the authors of SANE give permission for

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

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.
