<publication> "The Design and Implementation of the 4.3BSD
Unix Operating System", by Samuel J. Leffler, Marshall Kirk
McKusick, Michael J. Karels, and John S. Quarterman
(Addison-Wesley Publishers, 1989, ISBN 0-201-06196-1).
The standard reference book on the internals of BSD Unix.
So called because the cover has a picture depicting a little
devil (a visual play on daemon) in sneakers, holding a
pitchfork (referring to one of the characteristic features of
Unix, the "fork(2)" system call).
