The Lions Book
Since source code was available and the license was not explicit enough to forbid it, V6 was taken up as a teaching tool, notably by the University of California, Berkeley, Johns Hopkins University and the University of New South Wales (UNSW). Berkeley distributed a set of add-on program called the First Berkeley Software Distribution or 1BSD, which later became a full-fledged operating system. UNSW professor John Lions' famous Commentary on UNIX 6th Edition was an edited selection of the main parts of the kernel as implemented for a Digital PDP-11/40, and was the main source of kernel documentation for many early Unix developers. Due to license restrictions on later Unix versions, the book was mainly distributed by samizdat photo-copying.

Famous quotes containing the words lions and/or book:
“these heroic happy dead
who rushed like lions to the roaring slaughter
they did not stop to think they died instead
then shall the voice of liberty be mute?
He spoke. And drank rapidly a glass of water”
—E.E. (Edward Estlin)
“The trouble with writing a book about yourself is that you can’t fool around. If you write about someone else, you can stretch the truth from here to Finland. If you write about yourself the slightest deviation makes you realize instantly that there may be honor among thieves, but you are just a dirty liar.”
—Groucho Marx (1895–1977)
