works fine for me.  The OS is preselected, just wishing it would put
focus in the product name entry field.

That "formerly Avasys" part makes it sound as if AVASYS CORPORATION was
assimilated by EPSON CORPORATION.  That not being the case, I'd for one
be happy to see it gone.  It'd be nice though if AVASYS CORPORATION were
mentioned as the author/developer, maintainer and packager.

I would strongly suggest to remove the word "driver" as the binary
packages include a SANE backend and a SANE-ish frontend that works with
it (and the SANE net backend).  The backend itself can be used without
any DFSG non-free bits for most models via other SANE frontends.  That
said, the binary packages that are distributed do contain DFSG non-free

Contrary to the YaST text, you do not have to install the iscan-plugin
package.  You loose deskew and autocrop support, that's all.  Besides,
this support is only activated for the GT-S50, GT-S55, GT-S80, GT-S85
models (as of writing) and their overseas variants.

# BTW, you can recompile with ENABLE_SANEI_MAGIC defined to a non-zero
# value to use a DFSG free implementation that is activated (but mostly
# untested!) for all models.

BTW, the official name for the software is "Image Scan! for Linux".
Also, "dependant" is a noun, you probably want to use the adjective
which is "dependent".

Hope this helps,
