        don't touch the -I option unless you know what you are doing.
The default should be correct for the type of instrument you have
(Currently it's always 'A' type, because the Spectrolino/DTP41/i1pro
 all use incandescent illumination), and this will have been the
assumption in illumread as well, and it needs to match.
