<h1>SANE - License</h1>
</center>
<hr>
<p>
The information on this page is copied from the <a
href="LICENSE">LICENSE</a> file that is included in the sane-backends
distribution. It's only changed to use HTML and some links were added.
</p>
<p>
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.
</p>
<p>
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="html/">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.
</dd>
</dl>
