  28 ;;; Commentary:
  29
  30 ;; This program was written to protest the miss-named "Communications
  31 ;; Decency Act of 1996. This Act bans "indecent speech", whatever that is,
  32 ;; from the Internet. For more on the CDA, see Richard Stallman's essay on
  33 ;; censorship, included in the etc directory of emacs distributions 19.34
  34 ;; and up. See also http://www.eff.org/blueribbon.html.
  35
  36 ;; For many years, emacs has included a program called Spook. This program
  37 ;; adds a series of "keywords" to email just before it goes out. On the
  38 ;; theory that the NSA monitors people's email, the keywords would be
  39 ;; picked up by the NSA's snoop computers, causing them to waste time
  40 ;; reading your meeting schedule notices or other email boring to everyone
  41 ;; but you and (you hope) the recipient. See below (I left in the original
  42 ;; writeup when I made this conversion), or the emacs documentation at
  43 ;; ftp://prep.ai.mit.edu/pub/gnu/emacs-manual*.
  44
  45 ;; Bruce is a direct copy of spook, with the word "spook" replaced with
  46 ;; the word "bruce". Thanks to "esr", whoever he, she or it may be, this
  47 ;; conversion was an extremely easy piece of editing, suitable for a first
  48 ;; essay at elisp programming.
  49
  50 ;; You may think of the name as having been derived from a certain Monty
  51 ;; Python routine. Or from Lenny Bruce, who opposed censorship in his own
  52 ;; inimitable way. Bruce does exactly what Spook does: it throws keywords
  53 ;; into your email messages or other documents.
  54
  55 ;; However, in order to comply with the CDA as interpreted by Richard
  56 ;; Stallman (see the essay on censorship), bruce is distributed without a
  57 ;; data file from which to select words at random. Sorry about that. I
  58 ;; believe the average user will be able to come up with a few words on
  59 ;; his or her own. If that is a problem, feel free to ask any American
  60 ;; teenager, preferably one who attends a government school. Failing
  61 ;; that, you might write to Mr. Clinton or Ms Reno or their successors and
  62 ;; ask them for suggestions. Think of it as a public spirited act: the
  63 ;; time they spend answering you is time not spent persecuting someone
  64 ;; else. However, do ask them to respond by snail mail, where their
  65 ;; suggestions would be legal.
  66
  67 ;; To build the data file, just start a file called bruce.lines in the etc
  68 ;; directory of your emacs distribution. Note that each phrase or word has
  69 ;; to be followed by an ascii 0, control-@. See the file spook.lines in
  70 ;; the etc directory for an example. In emacs, use c-q c-@ to insert the
  71 ;; ascii 0s.
  72
  73 ;; Once you have edited up a data file, you have to tell emacs how to find
  74 ;; the program bruce. Add the following two lines to your .emacs file. Be
  75 ;; sure to uncomment the second line.
  76
  77 ;; for bruce mode
  78 ;; (autoload 'bruce "bruce" "Use the Bruce program to protest the CDA" t)
  79
  80 ;; Shut down emacs and fire it up again. Then "M-x bruce" should put some
  81 ;; shocking words in the current buffer.
  82
  83
  84 ;; Please note that I am not suggesting that you actually use this program
  85 ;; to add "illegal" words to your email, or any other purpose. First, you
  86 ;; don't really need a program to do it, and second, it would be illegal
  87 ;; for me to suggest or advise that you actually break the law. This
  88 ;; program was written as a demonstration only, and as an act of political
  89 ;; protest and free expression protected by the First Amendment, or
  90 ;; whatever is left of it.
  91
  92
  93 ;; We now return to the original writeup for spook:
  94
  95 ;; Steve Strassmann <straz@media-lab.media.mit.edu> didn't write the
  96 ;; program spook, from which this was adapted, and even if he did, he
  97 ;; really didn't mean for you to use it in an anarchistic way.
  98 ;;
  99 ;; To use this:
 100 ;;  Just before sending mail, do M-x spook.
 101 ;;  A number of phrases will be inserted into your buffer, to help
 102 ;;  give your message that extra bit of attractiveness for automated
 103 ;;  keyword scanners.  Help defeat the NSA trunk trawler!
