+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.).
+sane-backends is the collection of scanner interface libraries.
