+Description: API library for scanners [transitional package]
+ SANE stands for "Scanner Access Now Easy" and is an application
+ programming interface (API) that provides standardized access to any
+ raster image scanner hardware (flatbed scanner, hand-held scanner,
+ video- and still-cameras, frame-grabbers, etc.). The SANE standard is
+ free and its discussion and development are open to everybody. The
+ current source code is written to support several operating systems,
+ including GNU/Linux, OS/2, Win32 and various Unices and is available
+ under the GNU General Public License (commercial applications and
+ backends are welcome, too, however).
+ .
+ This package is here to ensure smooth upgrades. It can be removed when
+ you see fit.
