+ This file implements a SANE backend for the Kodak DC-25 (and
+ probably the DC-20) digital cameras. THIS IS EXTREMELY ALPHA CODE!
+ USE AT YOUR OWN RISK!!
+
+ (feedback to: dc25-devel@fales-lorenz.net)
+
+ This backend is based heavily on the dc20ctrl package by Ugo
+ Paternostro <paterno@dsi.unifi.it>. I've attached his header below:
