count-wordscount-words is an interactive compiled Lisp function in `
simple.el'. (count-words START END) Count words between START and END. If called interactively, START and END are normally the start and end of the buffer; but if the region is active, START and END are the start and end of the region. Print a message reporting the number of lines, words, and chars. If called from Lisp, return the number of words between START and END, without printing any message.
