<P>
Before we release a new version, I think a few documents should be
<BR>
updated.
<BR>
<P>The valid return values for sane_init() are unspecified. This was
<BR>
discussed in april (thread &quot;May sane_init fail?&quot;), where the problem
<BR>
was left unsolved. My proposal to require sane_init to return
<BR>
SANE_STATUS_GOOD before the backend could be used (this is how the dll
<BR>
backend works) was not accepted.
<BR>
<P>How to handle Automatic Document Feeders (ADF) is not documented.
<BR>
This is now handled by some backends and both scanimage and xsane, but
<BR>
as far as I know, the details are not written down anywhere.
<BR>
<P>Are there more topics that need to be resolved?
<BR>
<P>There should also be a new chapter in the documentation with
<BR>
information on the sanei API. As far as I know, there exist no
<BR>
documentation on this API.
<BR>
<P>The SANE Mustek 600 III EP Plus backend will need to be rewritten to
<BR>
use the sanei_pio API before I will accept it into the distribution.
<BR>
The author did not know about the sanei_pio API, and used Linux's
<BR>
ioperm() instead. I believe more documentation would have avoided
<BR>
this.
