classes. In addition, the internal module :mod:`_tkinter` provides a threadsafe
mechanism which allows Python and Tcl to interact.
-Tk is not the only GUI for Python; see section :ref:`other-gui-packages` for
-more information on other GUI toolkits for Python.
+: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

+libraries, see the :ref:`other-gui-packages` section.
