The information on this page is copied from the <a

This files attempts to clarify the licensing situation for the SANE
|
|
distribution. In case of doubt, the copyright information contained in
|

each file overrides what is said here.

SANE consists of three parts each of which has its own licensing
|
|
terms:
|
|
</p>
|
|
<blockquote>
|
|
<dl>
|
|
<dt>
|
|
The frontend programs.
|
|
</dt>
|
|
<dd>
|
|
These programs are generally protected by the GNU General Public
|
|
License. (See file <a href="COPYING">COPYING</a>.)
|
|
</dd>
|
|
|
|
<dt>
|
|
The backend libraries.
|
|
</dt>
|
|
<dd>
|
|
Most backend libraries are protected by the GNU General Public License (see file <a
|
|
href="COPYING">COPYING</a>), but as an exception, it is permissible to link against such a
|
|
library without affecting the licensing status of the program that uses the libraries.
|
|
For details, see the copyright notice at the head of the backend files (e.g., <a
|
|
href="dll.c">backend/dll.c</a>).<br>
|
|
|
|
Note that not all of the backends apply the exception and that some have additional
|
|
licensing constraints. E.g., the DC210 backend uses JPG code that is licensed as
|
|
described in <a href="README.djpeg">README.djpeg</a>.
|
|
</dd>
|
|
|
|
<dt>
|
|
The SANE API and network protocol as put forth in the standard document.
|
|
</dt>
|
|
<dd>
|
|
The <a href="https://sane-project.gitlab.io/standard/">standard</a> is considered to be in the public domain. Anyone is
|
|
free to implement SANE interface conforming applications or libraries in any way he or she
|
|
sees fit.

Frequently Asked Questions about the SANE licensing:
|
|
</p>
|
|
<blockquote>
|
|
<dl>
|
|
<dt>
|
|
Why don't you use the GNU LPGL ?
|
|
</dt>
|
|
<dd>
|
|
The reason SANE isn't licensed under the GNU LGPL is very
|
|
simple: the GNU LGPL didn't exist at the time SANE was first
|
|
released. So, the SANE Exception was added to the GNU GPL.
|
|
</dd>
|
|
<dt>
|
|
Why don't you relicense SANE, now that the GNU LGPL is
|
|
available ?
|
|
</dt>
|
|
<dd>
|
|
To relicense the various pieces of code composing SANE, each
|
|
and every copyright holder needs to agree with the
|
|
relicensing. Unfortunately, some of the (original) backend
|
|
authors cannot be contacted any longer, for various reasons;
|
|
not to mention each and every contributor who
|
|
sent in a patch. This effectively makes it impossible for
|
|
the SANE Project to relicense SANE.
