I would tell you if I could.

Karl, I copied this page to show others how little info there is on the
subject of modules and how useless that info is as an answer for a
simple question.  I.E.  What is a module?

I agree with you.  I too want to know what a module is.  The questions I
asked where potential answers that I hoped people who know more than me
would use as a guide.
