Steven, this text is fantastic! Well written and very interesting,
and yet not difficult to follow.
Thank you very much.
To help others with viewing trouble I've converted the text to unicode
HTML and put it online at

Steven - I hope you don't mind.
If anyone finds the HTML version useful (it should be viewable on any
system) - I am happy to do further conversions for subsequent lessons.
Looking forward to lesson two,
Walter
