I’ve heavily updated this page, most notably including
specifying mandatory arguments. That all you’ll get out of
me on the subject of keyword arguments. Of course, if anyone
has any suggestions/bugs/comments, I’d be delighted to hear them.
sir Gavin, I’m actually browsing the page now, including the main page. I
would suggest you put it under CodingInRuby->CodeSnippets&Examples. This way
I see big picture of your page 
Many thanks.
Gavin
