This version of the Image Scan for Linux software
contains only free software.

Therefore all proprietary binary-only i386-only software was removed and
the rest was changed so that the proprietary binary-only i386-only software
is no longer needed for compilation so that it now compiles and runs natively
even on non-i386 platforms.

The free Image Scan version contains only the epkowa backend for SANE.
For documentation see "man sane-epkowa".

Drawbacks:

The free version of the epkowa backend cannot work for those scanners
which require proprietary binary-only i386-only libraries which are
only included in the original iscan package.
At the moment those scanners are the following models:
Perfection 1250 / Perfection 1250 PHOTO / GT-7200,
Perfection 1260 / Perfection 1260 PHOTO / GT-7300,
Perfection 3170 PHOTO / GT-9400,
Perfection 2480 PHOTO / Perfection 2580 PHOTO / GT-F500 / GT-F550,
Perfection 4180 PHOTO / GT-F600,
Perfection 3490 PHOTO / Perfection 3590 PHOTO / GT-F520 / GT-F570,
Perfection 4490 PHOTO / GT-X750.
Those models don't work with the free iscan version.
Those models require the original iscan package which is only
available for i386-compatible platforms.

Some scanners require proprietary firmware files which are available
in the package iscan-firmware.
At the moment those scanners are the following models:
Perfection 3170 PHOTO / GT-9400,
Perfection 2480 PHOTO / Perfection 2580 PHOTO / GT-F500 / GT-F550,
Perfection 4180 PHOTO / GT-F600,
Perfection 3490 PHOTO / Perfection 3590 PHOTO / GT-F520 / GT-F570,
Perfection 4490 PHOTO / GT-X750.

The frontend /usr/bin/iscan was removed because it requires
proprietary binary-only i386-only software.
This should cause no problem because the backend epkowa runs now
natively even on non-i386 platforms so that all the usual frontends
(like scanimage, xscanimage, xsane, kooka) can be used even on
non-i386 platforms.
