OK, Many thanks to everyone on the helpful replies to my last request.  Especially that last one as it worked perfectly! (Skwire).

I have a situation where I need to do something with a pdf that I cannot find much information on other than the fact it exists.
Just like in CS5 and some other art programs, Adobe PDF's supposedly can be made with a background property of transparent.
I would like to be able to use this ability to stack multiple transparent overlays on top of on regular pdf that has normal black and white text.
Each of the overlays would need to be a separate file-name.pdf.  Each would need to allow only a single color for the text written on it.

The result would be an electronic version of an overlay book.  I need to keep it in pdf due to the (at least passable) security offered by pdf files.
I wish i knew of something better for security though.   I have talked to a place called lock-lizard but could not get any real feel for how much better
if any, their protection scheme might be.  So I guess a 2nd request would be for any kind of protection that can be placed on a document.  The intent is to prevent copying, printing, editing.  The usual stuff.  But it has to be put on a webpage so... not much I can do.

Yes, exactly!  The "sub sites" each have their own "door" to the main site; their own "Index.php". 
Being able to run a quick list of working hyperlinks whenever I need a current one would be very handy.  The "sub-sites" change.  Sometimes new ones, sometimes old ones gone.  One problem is the APACHE layout included a single main "sub-site" sub-directory called "\webroot\" that shows when I pull a "DIR" command.  It  can't be left in the hyperlink or it wont work. "www.abc.com\webroot\name\project\index.php" is the best I can get. Then delete the "/webroot" afterward.

I ran across the perfect script to do this somewhere years back but I have no idea what it was or where I found it :(

This is probably too easy for most of you but I just can't seem to put the parts together right.

I need a simple script or batch file that will create a list of WEBSITE hyperlinks from the subfolders in a main directory.  The main directory is the main website but each person in the class has their own projects that can each be entered directly by going straight to their own index.php file

Example  Main directory would be www.example.com
First level Subdirectories would be names  like "john", mary", "bill"  etc
Third level Subdirectories would be their sites.  The names could be anything.
maybe first_try, second_try, third_try

The end result would be a word document full of working weblinks:  www.example.com/john/first_try
then www.example.com/john/second_try, then www.example.com/john/third_try

Then on to the next person in the 2nd level and each of their projects and so on.

This is for a setup where the people (second subdir level) as well as each one's projects (third level subdir)
will change and each time it does I have to retype the whole list.  I used to have a program that did this to some extent but dont remember the name.  My efforts at doing it using variables in a batch file are not coming along too well and this month it would almost be faster to type them one at a time.
Currently that would total about 150 weblinks :(  SO..  I was hoping someone better than me might have a solution :)
