[sane-devel] fail: open driver for Epson Perfection V100

[m. allan noah]

Don't be discouraged. Writing a scanner driver is very difficult work,
especially if you lack documentation. Writing the epjitsu backend was
so frustrating, I doubt I will work on such a stupid scanner again.
Perhaps A. Imass will have some interest is continuing your work :)
