The balance of this document describes the actual code of
the pageturner.py widget.
First there is a brief opening comment, the usual Python documentation string for the module:
"""pageturner.py: Tkinter widget for viewing a sequence of content pages
Do not edit this file. It is extracted automatically from its
documentation file. See:
http://www.nmt.edu/tcc/help/lang/python/examples/pageturner/
"""
Next is the obligatory importation of the Tkinter module.
