accessibility features such as text-to-speech, which is useful for end-users
who are visually challenged or cannot access the application for whatever
reason.  The most common use case where text-to-speech comes in handy is when
the end-user is driving and cannot attend the incoming messages on the phone.
In such a scenario, the messaging application can read out the incoming
message.")))

SIP comprises a code generator and a Python module.  The code generator
processes a set of specification files and generates C or C++ code, which
is then compiled to create the bindings extension module.  The SIP Python
module provides support functions to the automatically generated code.")

comes with the Shiboken2 CPython binding code generator, which can be used to
generate Python bindings for your C or C++ code.")

    (description
     "@code{libQGLViewer} is a C++ library based on Qt that eases the creation
of OpenGL 3D viewers.

It provides some of the typical 3D viewer functionalities, such as the
possibility to move the camera using the mouse, which lacks in most of the
other APIs.  Other features include mouse manipulated frames, interpolated
keyFrames, object selection, stereo display, screenshot saving and much more.
It can be used by OpenGL beginners as well as to create complex applications,
being fully customizable and easy to extend.")
