This comes up on the mailing list every 6 months or so, but noone ever
says what the purpose is.

If you chose a supported scanner, sane will give you some code to work
from, but you likely wont be able to use it without significant
modification, if at all.

Every scanner is different, so without more info about your needs, i
dont think i can comment further.
