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