+
+Tk/Tcl has long been an integral part of Python. It provides a robust and
+platform independent windowing toolkit, that is available to Python programmers
+using the :mod:`Tkinter` module, and its extension, the :mod:`Tix` module.
+
+The :mod:`Tkinter` module is a thin object-oriented layer on top of Tcl/Tk. To
+use :mod:`Tkinter`, you don't need to write Tcl code, but you will need to
+consult the Tk documentation, and occasionally the Tcl documentation.
+:mod:`Tkinter` is a set of wrappers that implement the Tk widgets as Python
+classes. In addition, the internal module :mod:`_tkinter` provides a threadsafe
+mechanism which allows Python and Tcl to interact.
+
+:mod:`Tkinter`'s chief virtues are that it is fast, and that it usually comes
+bundled with Python. Although it has been used to create some very good
+applications, including IDLE, it has weak documentation and an outdated look and
+feel. For more modern, better documented, and much more extensive GUI
+libraries, see the :ref:`other-gui-packages` section.
