<PUblication> "Introduction to Automata Theory, Languages, and ComPUtation", by John Hopcroft and Jeffrey Ullman, (Addison-Wesley, 1979). So called because the cover depicts a girl (PUtatively Cinderella) sitting in front of a Rube Goldberg device and holding a rope coming out of it. On the back cover, the device is in shambles after she has (inevitably) PUlled on the rope. See also book titles. [Jargon File] (1996-12-03)
