"""       xturtle-example-suite:

             xtx_peace.py

A very simple drawing suitable as a beginner's
programming example.

A bit more advanced than xtx_peace.py: uses a few
commands from xturtle.py (such as hideturtle() and
the xturtle vocabulary.

USe of variables makes it more versatile and adaptable
