	demo0.py

	This very simple application program merely adds two
	specified integers and prints out the resulting sum.
	It is written using the Python programming language,
	to illustrate the distinction between a "high-level"
	language and a "low-level" language (like assembly).
	This demo should be compared with 'demo2.s' which is
	a "low-level" version of this very same computation.

		execute using:  $ python demo0.py
