     \title The qtmain Library
     \ingroup licensing
     \brief Commercial and \l{BSD 3-clause "New" or "Revised" License}.

     qtmain is a helper library that enables the developer to write a
     cross-platform main() function on Windows.
     If you do not use \l qmake, \l {Qbs Manual}{qbs}, or other build tools such as
     \l{CMake Documentation}{CMake}, then you need to link against the
     \c qtmain library.

     The qtmain library is statically linked with the application.
     To avoid issues with static linking and the
     \l{GNU Lesser General Public License (LGPL)},
     it is licensed both under the commercial licenses,
     and the \l{BSD 3-clause "New" or "Revised" License}.

     \title The QtOpenGLExtensions Library
     \ingroup licensing
     \brief Commercial and \l{BSD 3-clause "New" or "Revised" License}.

     QtOpenGLExtensions is a library that contains auto-generated wrappers
     for OpenGL extensions from the Khronos registry.

     To include the definitions of the module, use the following directive:

     \code
         #include <QtOpenGLExtensions>
     \endcode

     To link against the module, add this line to your qmake .pro file:

     \code
         QT += openglextensions
     \endcode

     Because applications do typically use only few extensions, the library is
     statically linked with the application. To avoid issues with
     \l{GNU Lesser General Public License (LGPL)} in this case, the library is
     licensed both under the commercial licenses, and the
     \l{BSD 3-clause "New" or "Revised" License}.
