- executable hosting the Python interpreter. If there isn't a script that will be

- to initialize ``sys.argv``, a fatal condition is signalled using

+ A boolean value indicating whether this thread is a daemon thread (True) or

+ threads created in the main thread default to :attr:`daemon` = ``False``.
The entire Python program exits when no alive non-daemon threads are left.

+ttk: Themed Widgets for Tk
+--------------------------
+
+Tcl/Tk 8.5 includes a set of themed widgets that re-implement basic Tk
+widgets but have a more customizable appearance and can therefore more
+closely resemble the native platform's widgets. This widget
+set was originally called Tile, but was renamed to Ttk (for "themed Tk")
+on being added to Tcl/Tck release 8.5.
+
+XXX write a brief discussion and an example here.
+
+The :mod:`ttk` module was written by Guilherme Polo and added in
+:issue:`2983`. An alternate version called ``Tile.py``, written by
+Martin Franklin and maintained by Kevin Walzer, was proposed for
+inclusion in :issue:`2618`, but the authors argued that Guilherme
+Polo's work was more comprehensive.
