Collection of open-source SANE backends (device drivers).
SANE is a universal scanner interface providing standardized access to
any raster image scanner hardware: flatbed scanners, hand-held scanners,
video- and still-cameras, frame-grabbers, etc. For a list of supported
scanners, see http://www.sane-project.org/sane-backends.html.
