\title Qt Licensing
\brief Information about licenses and licensing issues.
Qt is available under different licensing options designed to accommodate
the needs of our various users:
\list
\li Qt licensed under \e commercial licenses is appropriate for
development of proprietary/commercial software where you do not want
to share any source code with third parties or otherwise cannot
comply with the terms of the GNU LGPL version 3.
\li Qt licensed under the \l{GNU Lesser General Public License (LGPL)}
version 3 is appropriate for the development of Qt applications
provided you can comply with the terms and conditions of the GNU LGPL
version 3 (or GNU GPL version 3).
\endlist
Qt contains also \l {Licenses Used in Qt}{third-party code} that is licensed
under specific open-source licenses from the original authors.
\note For open-source licensed Qt, some specific parts (modules) are not
available under the GNU LGPL version 3, but under the
\l {GNU General Public License (GPL)} instead. See
the list of \l {gpl-licensed-addons}{Qt modules} for details. For commercial
licensees, all modules are available under a single, commercial Qt
license.
\e {Qt documentation} is available under commercial licenses from
The Qt Company, and under the terms of the \l{GNU Free
Documentation License (FDL)} version 1.3, as published by the Free Software
Foundation.
\e {Qt examples} are available under commercial licenses from The Qt Company,
and under a \l{License of Qt examples}{BSD-3-clause} license.
See \l{http://qt.io/licensing/} for an overview of Qt licensing.

\title Licenses Used in Qt
\brief Information about other licenses and third-party code used in Qt.
Qt contains some code that is not provided under the
\l{GNU Lesser General Public License (LGPL)} or the
\l{Qt Commercial License}, but rather under specific licenses from the
original authors.
The Qt Company gratefully acknowledges these and other contributions to Qt.
We recommend that programs that use Qt also acknowledge these contributions,
and quote these license statements in an appendix to the documentation.
\note You only need to comply with (and acknowledge) the licenses of the
third-party components that you are using with your application.
Click the name of the component to see the licensing details.

\title Mesa llvmpipe
\ingroup licensing
\brief MIT License
Mesa is a 3-D graphics library with an API which is very similar to that of OpenGL.
The llvmpipe software renderer allows running of OpenGL applications without any
hardware / driver support.
Shipped as part of the binary packages for Windows (opengl32sw.dll).

(This is a heavily cut-down "BSD license".)
This differs from Colin Plumb's older public domain implementation in that
no exactly 32-bit integer data type is required (any 32-bit or wider
unsigned integer data type will do), there's no compile-time endianness
configuration, and the function prototypes match OpenSSL's. No code from
Colin Plumb's implementation has been reused; this comment merely compares
the properties of the two independent implementations.
The primary goals of this implementation are portability and ease of use.
It is meant to be fast, but not as fast as possible. Some known
optimizations are not included to reduce source code size and avoid
compile-time configuration.
