;;; Commentary:
-; Steve Strassmann (straz@media-lab.media.mit.edu) didn't write
-; this, and even if he did, he really didn't mean for you to use it
-; in an anarchistic way.
-; May 1987
-
-; To use this:
-; Make sure you have the variable SPOOK-PHRASES-FILE pointing to
-; a valid phrase file. Phrase files are in the same format as
-; zippy's yow.lines (ITS-style LINS format).
-; Strings are terminated by ascii 0 characters. Leading whitespace ignored.
-; Everything up to the first \000 is a comment.
-;
-; Just before sending mail, do M-x spook.
-; A number of phrases will be inserted into your buffer, to help
-; give your message that extra bit of attractiveness for automated
-; keyword scanners.
