+images from it.  You can photocopy multi-page documents and save, fax, print,
+or e-mail your scanned images.  It is highly configurable and exposes all
+device settings, letting you fine-tune the final result.  It can also be used
+as a GIMP plugin to acquire images directly from a scanner.
+
+XSane talks to scanners through the @acronym{SANE, Scanner Access Now Easy}
+back-end library, which supports almost all existing scanners.")
