You're not going to defeat this by being clever enough, the same way you can't change the value of pi by being clever enough.

The kind of security you want can be achieved by not letting their computer read it.

i understand what you're saying. but there's been quite a few things that i've read couldn't be done, but ended up being doable. they just required "being clever" enough, and having the excessive dedication time it takes to actually write something noone in their right mind would want to try to break unless given a massive monetary incentive to do so. and even then, you'd have to be in the mind of the coder to know what he's doing, especially if the script or code is large in size, void of comments, and not written in a way that makes it easily comprehended. but thanks for your input. much appreciated.

a5booklet

A5BOOKLET(1)						      General Commands Manual						      A5BOOKLET(1)

NAME

       a5booklet - copy two A5 pages from a .dvi file to one A4 page in another.

SYNOPSIS

       a5booklet file[.dvi]

DESCRIPTION

       A5booklet  is  a  little  script that allows you to typeset two A5 pages next to eachother on a single A4 page (landscape), combining pages
       from the original file in such a way that after double sided printing and some reshuffeling of the pages you get a nice a5 booklet that	is
       ready for a staple in the middle.

       The script calls a very clever program dvidvi, written by Tomas Rokicki (the author of dvips), that does the real work.

       The output is written to two files, file-1.dvi and file-2.dvi

       dvips -ta4 -tlandscape file-1

       then put the stack upside doen in the printer, and print the second file using

       dvips -ta4 -tlandscape file-2

       Make  sure  that  the  bottom  of  the A5-pages is on the correct side of the paper when you put the stack back for printing the back side.
       After the two print jobs, you must re-shuffle the paper stack before you can staple it.

SEE ALSO

       tex(1), dvips(1), dvidvi(1).

BUGS

       The script has A4 papersize hardwired into it.  Admittedly, a European-centered way of thinking.

       Page number 1 is always the first page in the original .dvi file, not the page numbered 1 by TeX's numbering scheme.

AUTHOR

       A5booklet is written by David A. van Leeuwen (david@ElseWare.cistron.nl), but is is not original in any way.  The main two  lines  that	do
       the work are inspired from the man page of dvidvi.  A5booklet is available under the conditions of the Gnu Public Licence.
