// Description: The Curses! program is a random text generator. This program
// generates curses such as "May a thousand flees merrily infest
// your red Corvette!" Curses! was originally conceived by
// Tom Dwyer and Margot Crichfield in 1978. This version is
// based on Russ Walter's description of their work.
//
// This program works by maintaining three arrays of
// words/phrases; nouns, verbs, and objects. The computer
// randomly selects from each array and fills in the template:
//
// May noun verb your object !
//
// Templates are often employed to produce textual output that
// is human readable. However in production systems words and
// phrases are rarely chosen so randomly.
