:Dragon Book: n. The classic text "Compilers: Principles,
Techniques and Tools", by Alfred V. Aho, Ravi Sethi, and Jeffrey D.
Ullman (Addison-Wesley 1986; ISBN 0-201-10088-6), so called because
of the cover design featuring a dragon labeled `complexity of
compiler design' and a knight bearing the lance `LALR parser
generator' among his other trappings. This one is more
specifically known as the `Red Dragon Book' (1986); an earlier
edition, sans Sethi and titled "Principles Of Compiler Design"
(Alfred V. Aho and Jeffrey D. Ullman; Addison-Wesley, 1977; ISBN
0-201-00022-9), was the `Green Dragon Book' (1977). (Also `New
Dragon Book', `Old Dragon Book'.) The horsed knight and the
Green Dragon were warily eying each other at a distance; now the
knight is typing (wearing gauntlets!) at a terminal showing a
video-game representation of the Red Dragon's head while the rest
of the beast extends back in normal space. See also {{book
titles}}.
