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

The proprietary binary-only i386-only "libesint*" driver libraries
are available in the separate package iscan-proprietary-drivers.

The "esfw*.bin" firmware files are available in the separate
package iscan-firmware.

The proprietary binary-only i386-only "libesmod" library is removed
from this package. It is required by the "/usr/bin/iscan" front-end.
This package is built without the front-end.

This package contains only the epkowa back-end for SANE, which
compiles and runs natively even on non-i386 platforms.
For documentation, see "man sane-epkowa".

Drawbacks:

The free version of the epkowa back-end cannot work for those scanners
that require proprietary binary-only i386-only libraries, available
in the separate package iscan-proprietary-drivers. At the moment,
those scanners are the following models:
Perfection 1250 / GT-7200U,
Perfection 1250 PHOTO,
Perfection 1260 / GT-7300U,
Perfection 1260 PHOTO,
Perfection 2480 PHOTO / GT-F500,
Perfection 2580 PHOTO / GT-F550,
Perfection 3170 PHOTO / GT-9400UF,
Perfection 3490 PHOTO / GT-F520,  
Perfection 3590 PHOTO / GT-F570,  
Perfection 4180 PHOTO / GT-F600,  
Perfection 4490 PHOTO / GT-X750,  
Perfection V10 / GT-S600,
Perfection V100 PHOTO / GT-F650,
Perfection V200 PHOTO / GT-F670,
Perfection V350 PHOTO / GT-F700.
Stylus CX4300,
Stylus CX4400,
Stylus CX5500,
Stylus CX5600,
Stylus DX4400.

Those models do not work with the free iscan version. Those models require
the original iscan package and the iscan-proprietary-drivers package, which
are only available for i386-compatible platforms.

Some scanners require proprietary firmware files that are available
in the package iscan-firmware. At the moment, those scanners are the
following models:
Perfection 2480 PHOTO / GT-F500,
Perfection 2580 PHOTO / GT-F550,
Perfection 3170 PHOTO / GT-9400UF,
Perfection 3490 PHOTO / GT-F520,
Perfection 3590 PHOTO / GT-F570,
Perfection 4180 PHOTO / GT-F600,
Perfection 4490 PHOTO / GT-X750,
Perfection V10 / GT-S600,
Perfection V100 PHOTO / GT-F650,
Perfection V200 PHOTO / GT-F670,
Perfection V350 PHOTO / GT-F700.

The front-end /usr/bin/iscan was removed because it requires the proprietary
binary-only i386-only "libesmod" library. This should cause no problem
because the back-end epkowa runs now natively even on non-i386 platforms
so that all the usual front-ends (like scanimage, xscanimage, xsane,
and kooka) can be used even on non-i386 platforms.
