    \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).
      \li Qt components licensed under the \l{Qt Marketplace License Agreement}
          are appropriate for the development of Qt applications commonly with
          Qt software components licensed under the commercial or GNU LGPL
          version 3 (or GNU GPL version 3) terms and conditions.
    \endlist

    Qt contains also \l {Third-Party Code 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.

    //! TODO: Use grouping for automatically-generated list
    \details {Modules available under GNU General Public License v3}

    \enddetails

    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.

    \l {Qt Educational License}{Educational licenses} are available for students
    and educators in qualified educational institutions or universities.

    See \l{http://qt.io/licensing/} for an overview of Qt licensing.

    sales; see \l{http://www.qt.io/locations/} for contact details.

    \section1 Third-Party Code in Qt

    The following page documents the open-source licenses used in different
    parts of Qt:

    \list
        \li \l {Third-Party Code Used in Qt}
    \endlist

    \section1 Software Bill of Materials (SBOM)

    Starting from Qt 6.8, Software Bill of Materials (SBOM) documents of
    third-party components in Qt are available. Information such as copyrights,
    licenses, versions, source repositories, and other relevant information are
    declared in SPDX 2.3 format.

    \list
        \li \l {Software Bill of Materials}
    \endlist

    \section1 Export Controls

    Many jurisdictions impose export controls for various hardware and software
    products. In general, the mass-market Qt framework as well as the related
    tools provided by the Qt Group do not contain functionality that would
    cause them to be under tight regulations. The following page lists the
    relevant information about export controls.

    \title Third-Party Code Used in Qt
    \brief Information about third-party code used in Qt.

    Qt libraries and plugins can contain code that is not intellectual
    property of The Qt Company, but is available under specific open-source
    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 acknowledge and comply with the licenses of the
    third-party components that you are actually shipping with your
    application. Click the name of the component to see the licensing details.

    \b {Third-party Licenses}

    The following sections list third-party components in Qt \QtVersion, grouped by
    \l{All Modules}{Qt module}. If the third-party component itself consists of
    parts that are of a different origin (so-called
    4th-party or Nth-party code), these are listed, too.

    Starting from Qt 6.8, Software Bill of Materials (SBOM) documents of
    third-party components in Qt are available. Information such as copyrights,
    licenses, versions, source repositories, and other relevant information are
    declared in SPDX 2.3 format. For more information, visit the
    \l {Software Bill of Materials} page.

    claimed, and the software is hereby placed in the public domain.
    In case this attempt to disclaim copyright and place the software in the

    Redistribution and use in source and binary forms, with or without
    modification, are permitted.

    There's ABSOLUTELY NO WARRANTY, express or implied.

    (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.
