	At the risk of being blunt, unless one understands what one is
	programming, one is in deep trouble.  (and, to be fair, the programmer
	_is_ asking.)  Its not hard to come up with a a program to spin some
	numbers.  The trick is to have them mean something.  As the Bumble Bee.

	Yeah Verily.  Wisdom in this...

	Like much else, its a learning process.  Having once (or twice or...)
	learnt something, hopefully it IS known.  And, hopefully the next
	<whatever> comes closer, with less tweaking....
