   True, I ran the whole Canon package.  I noticed the files whose naming was suggestive of a connection with SANE, but found SANE clearly had nothing to do with the whole package.  I notice the licence at (for example) http://support-au.canon.com.au/contents/AU/EN/0100084201.html includes the GPL, Version 2.

   Perhaps Wang would be good enough to clarify the matter?

   In relation to my previous post, if it's possible to accomodate manufacturers' sensitivities regarding proprietary code within the constraints of the GPL and overall SANE architecture (especially a major player such as Canon) the status of SANE as a de-facto standard would be greatly helped.
