Good!

Ok. Do you use it for saving in a different image format?
I don't want to add the --raw option, because that would open SANE for
non-SANE compliant frame types. So you convert e.g. from pnm to png?

Ok.

If they aren't too big (say <20 KB), send them to the list. Otherwise,
put them on a web server or send them to me.

Documentation (--help and manpage update) would be nice.

I think scanadf is older and was seperated from SANE for quite a long
time. Maybe the author of the --batch-scan commands didn't know or
didn't like it?
