+   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:
