  25 ;;; Commentary:
  26
  27 ;; This program was written to protest the miss-named "Communications
  28 ;; Decency Act of 1996. This Act bans "indecent speech", whatever that is,
  29 ;; from the Internet. For more on the CDA, see Richard Stallman's essay on
  30 ;; censorship, included in the etc directory of emacs distributions 19.34
  31 ;; and up. See also http://www.eff.org/blueribbon.html.
  32
  33 ;; For many years, emacs has included a program called Spook. This program
  34 ;; adds a series of "keywords" to email just before it goes out. On the
  35 ;; theory that the NSA monitors people's email, the keywords would be
  36 ;; picked up by the NSA's snoop computers, causing them to waste time
  37 ;; reading your meeting schedule notices or other email boring to everyone
  38 ;; but you and (you hope) the recipient. See below (I left in the original
  39 ;; writeup when I made this conversion), or the emacs documentation at
  40 ;; ftp://prep.ai.mit.edu/pub/gnu/emacs-manual*.
  41
  42 ;; Bruce is a direct copy of spook, with the word "spook" replaced with
  43 ;; the word "bruce". Thanks to "esr", whoever he, she or it may be, this
  44 ;; conversion was an extremely easy piece of editing, suitable for a first
  45 ;; essay at elisp programming.
  46
  47 ;; You may think of the name as having been derived from a certain Monty
  48 ;; Python routine. Or from Lenny Bruce, who opposed censorship in his own
  49 ;; inimitable way. Bruce does exactly what Spook does: it throws keywords
  50 ;; into your email messages or other documents.
  51
  52 ;; However, in order to comply with the CDA as interpreted by Richard
  53 ;; Stallman (see the essay on censorship), bruce is distributed without a
  54 ;; data file from which to select words at random. Sorry about that. I
  55 ;; believe the average user will be able to come up with a few words on
  56 ;; his or her own. If that is a problem, feel free to ask any American
  57 ;; teenager, preferably one who attends a government school. Failing
  58 ;; that, you might write to Mr. Clinton or Ms Reno or their successors and
  59 ;; ask them for suggestions. Think of it as a public spirited act: the
  60 ;; time they spend answering you is time not spent persecuting someone
  61 ;; else. However, do ask them to respond by snail mail, where their
  62 ;; suggestions would be legal.
  63
  64 ;; To build the data file, just start a file called bruce.lines in the etc
  65 ;; directory of your emacs distribution. Note that each phrase or word has
  66 ;; to be followed by an ascii 0, control-@. See the file spook.lines in
  67 ;; the etc directory for an example. In emacs, use c-q c-@ to insert the
  68 ;; ascii 0s.
  69
  70 ;; Once you have edited up a data file, you have to tell emacs how to find
  71 ;; the program bruce. Add the following two lines to your .emacs file. Be
  72 ;; sure to uncomment the second line.
  73
  74 ;; for bruce mode
  75 ;; (autoload 'bruce "bruce" "Use the Bruce program to protest the CDA" t)
  76
  77 ;; Shut down emacs and fire it up again. Then "M-x bruce" should put some
  78 ;; shocking words in the current buffer.
  79
  80
  81 ;; Please note that I am not suggesting that you actually use this program
  82 ;; to add "illegal" words to your email, or any other purpose. First, you
  83 ;; don't really need a program to do it, and second, it would be illegal
  84 ;; for me to suggest or advise that you actually break the law. This
  85 ;; program was written as a demonstration only, and as an act of political
  86 ;; protest and free expression protected by the First Amendment, or
  87 ;; whatever is left of it.
  88
  89
  90 ;; We now return to the original writeup for spook:
  91
  92 ;; Steve Strassmann <straz@media-lab.media.mit.edu> didn't write the
  93 ;; program spook, from which this was adapted, and even if he did, he
  94 ;; really didn't mean for you to use it in an anarchistic way.
  95 ;;
  96 ;; To use this:
  97 ;;  Just before sending mail, do M-x spook.
  98 ;;  A number of phrases will be inserted into your buffer, to help
  99 ;;  give your message that extra bit of attractiveness for automated
 100 ;;  keyword scanners.  Help defeat the NSA trunk trawler!
