NAME
       sane-snapscan - SANE backend for AGFA SnapScan flatbed scanners

DESCRIPTION
       The sane-snapscan library implements a SANE (Scanner Access Now Easy)
       backend that provides access to AGFA SnapScan flatbed scanners. At
       present, the following scanners are supported from this backend: AGFA
       SnapScan 300, 310, 600, and 1236s, 1236u, 1212u, e20, e25, e40, e50,
       e60, Vuego 310s, Acer 300f, 310s, 610s, 610plus, Prisa 620s, Prisa
       620u, Prisa 620ut, Prisa 640u, Prisa 640bu, Prisa 1240, Prisa 3300,
       Prisa 4300, Prisa 5300 and Guillemot Maxi Scan A4 Deluxe (SCSI) (with
       varying success).

DEVICE NAMES
       This backend expects device names of the form:

              special

       Where special is the path-name for the special device that corresponds
       to a SCSI scanner. For SCSI scanners, the special device name must be a
       generic SCSI device or a symlink to such a device.  Under Linux, such a
       device name could be /dev/sga or /dev/sge, for example.  See
       sane-scsi(5) for details.

       For USB scanners the devicename must contain the keyword "usb", as in
       /dev/usbscanner or /dev/usb/scanner0.  For scanners that need a
       firmware upload before scanning add a line starting with "firmware"
       followed by the fully qualified path to your firmware file, e.g.

              firmware /usr/local/share/sane/snapscan/firmware.bin

       For further details read http://snapscan.sourceforge.net.


CONFIGURATION
       The contents of the snapscan.conf file is a list of device names that
       correspond to SnapScan scanners.  Empty lines and lines starting with a
       hash mark (#) are ignored.  See sane-scsi(5) on details of what
       constitutes a valid device name.


FILES
       /etc/sane.d/snapscan.conf
              The backend configuration file (see also description of
              SANE_CONFIG_DIR below).

       /usr/local/lib/sane/libsane-snapscan.a
              The static library implementing this backend.

       /usr/local/lib/sane/libsane-snapscan.so
              The shared library implementing this backend (present on systems
              that support dynamic loading).

ENVIRONMENT
       SANE_CONFIG_DIR
              This environment variable specifies the list of directories that
              may contain the configuration file.  Under UNIX, the directories
              are separated by a colon (`:'), under OS/2, they are separated
              by a semi-colon (`;').  If this variable is not set, the
              configuration file is searched in two default directories:
              first, the current working directory (".") and then in
              /etc/sane.d.  If the value of the environment variable ends with
              the directory separator character, then the default directories
              are searched after the explicitly specified directories.  For
              example, setting SANE_CONFIG_DIR to "/tmp/config:" would result
              in directories "tmp/config", ".", and "/etc/sane.d" being
              searched (in this order).

       SANE_DEBUG_SNAPSCAN
              If the library was compiled with debug support enabled, this
              environment variable controls the debug level for this backend.
              E.g., a value of 255 requests all debug output to be printed.
              Smaller levels reduce verbosity.
