 %description
 Scanner Access Now Easy (SANE) is a universal scanner interface.  The
 SANE application programming interface (API) provides standardized
 access to any raster image scanner hardware (flatbed scanner,
-hand-held scanner, video and still cameras, frame-grabbers, etc.). If
-they're using SANE, developers can write image-processing applications
-without having to think about the peculiarities of individual devices.
-SANE also makes it possible to write a device driver once, which can
-then be used by any SANE-compliant application. SANE currently
-includes drivers for some Epson SCSI scanners, HP ScanJet SCSI
-scanners, Microtek SCSI scanners, Mustek SCSI flatbed scanners, PINT
-devices, most UMAX SCSI scanners, Connectix QuickCam, and other SANE
-devices via network. Note that this package does not enable network
-scanning by default.  If you wish to enable network scanning, read the
-saned(1) manpage.  If you'd like to develop SANE modules, you should
-also install the sane-backends-devel package.
