eintr: Why Count Words

 
 Counting words
 ==============
 
 The standard Emacs distribution contains functions for counting the
 number of lines and words within a region.
 
    Certain types of writing ask you to count words.  Thus, if you write
 an essay, you may be limited to 800 words; if you write a novel, you may
 discipline yourself to write 1000 words a day.  It seems odd, but for a
 long time, Emacs lacked a word count command.  Perhaps people used Emacs
 mostly for code or types of documentation that did not require word
 counts; or perhaps they restricted themselves to the operating system
 word count command, ‘wc’.  Alternatively, people may have followed the
 publishers’ convention and computed a word count by dividing the number
 of characters in a document by five.
 
    There are many ways to implement a command to count words.  Here are
 some examples, which you may wish to compare with the standard Emacs
 command, ‘count-words-region’.
