Just in time to make your April Fools jokes, another wasteful UNIX
filter: ransom! This program will enhance your text with randomly
assigned troff codes to control fonts, sizes and minor vertical
perturbations. The result is text that doesn't look enough like you
cut words out of the Times and glued them to a sheet to make an
untraceable ransom note. Please do not use this program to commit
crimes, but if you happen to collect some money, I think it would be
fair to send a few percent to me (in unmarked bills).
#! /bin/sh
# This is a shell archive, meaning:
# 1. Remove everything above the #! /bin/sh line.
# 2. Save the resulting text in a file.
# 3. Execute the file with /bin/sh (not csh) to create:
# ransom.1
# ransom.c
export PATH; PATH=/bin:/usr/bin:$PATH
if test -f 'ransom.1'
then
echo shar: "will not over-write existing file 'ransom.1'"
else
cat << \SHAR_EOF > 'ransom.1'

.SH NAME
ransom \- generate a ransom letter for troff
.SH USAGE
.I ransom
[commands]
.SH DESCRIPTION
.I ransom
reads plain text from the standard input for which it
randomly assigns font, size, and vertical motion control codes
to individual words.
The output should be processed by
.I troff.
The goal is to produce text that looks like it has been
cut out from newspapers and haphazardly glued to a ransom note.
Optionally,
.I troff
commands can be supplied on the command line to aid in the
formatting of the ransom note.
.SH EXAMPLE
The following example makes a fortune look like a ransom note.
It puts the fortune in no-file mode, sets the page offset to one inch,
and spaces one inch before the fun begins.
.ce
fortune | ransom .nf .po1i ".sp 1i" | troff
.SH BUGS
The output is hard to read.
.SH "SEE ALSO
jive(1), valspeak(1), fortune(1) for other wastes of time.
.SH AUTHOR
We need not use any names here.
