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:
“No stout
Lesson showed how to chat with death. We brought
No brass fortissimo, among our talents,
To holler down the lions in this air.”
—Gwendolyn Brooks (b. 1917)
“Today I begin to understand what love must be, if it exists.... When we are parted, we each feel the lack of the other half of ourselves. We are incomplete like a book in two volumes of which the first has been lost. That is what I imagine love to be: incompleteness in absence.”
—Edmond De Goncourt (1822–1896)
