And that is the problem: a user that only uses gscan2pdf won't know
the other options are there, and so won't report them missing.

Yes- your Perl bindings are most useful, hopefully you will find the
time to convert the app to use them :)

Hopefully the backend will breakup the options into reasonable sized
chunks with SANE_TYPE_GROUP options, and you could add a tab for each
group. Also, some options will have SANE_CAP_ADVANCED set, and you can
hide those until a user requests to see adv options.
