Richard Suchenwirth 2014-01-19 - The following code snippet does nothing special. It just inserts a famous (though mutilated, Latin) text (which is often used to simulate more meaningful text in layout tests) into a suitable Tk widget - best use text.
For background information, see https://en.wikipedia.org/wiki/Lorem_ipsum
proc lorem {{w .t}} {
$w insert end "Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.
