This file implements a SANE backend for the Kodak DC-240
digital camera. THIS IS EXTREMELY ALPHA CODE! USE AT YOUR OWN RISK!!
(feedback to: gphoto2-devel@fales-lorenz.net)
This backend is based somewhat on the dc25 backend included in this
package by Peter Fales, and the dc210 backend by Brian J. Murrell
