It can, however, tell the frontend a list of settings that are
important, which are then to be saved into the output file by the
frontend. In the case of coolscan2, this could be exposure and focus
information, which would indeed be useful.

To sensibly do this, we need to amend the SANE standard, however, in
such a way that the backend can specify which options are to be saved.

I'm not familiar with EXIF, so would you mind if I asked what exactly
it is? Is it just information embedded into a JPG file, or can it be
used with other formats as well?
