/* sane - Scanner Access Now Easy.

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.
