     "XSane is a graphical interface for controlling a scanner and acquiring
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.")
