Well, it *is* GNU software...
Reminds me of a story where a Ph.D. student put the following footnote on
page 50 of his thesis: "I owe you a beer". Then, on page 150 of his
thesis, he put another footnote: "I owe you a case of beer". His advisor
comes to the defense and opens up with: "I read your thesis, and you owe
me a beer".
In other words, they are just checking if you're paying attention.
Apparently, you are.
