Trying to combine .pptx files using javascript

I found this on google docs that will allow automated ppt combining.

http://code.google.com/p/powerpointjoin/

I combine over 50 ppt's daily, and I'd like to automate it so I can have a nice cup of coffee in the time I save...

The code posted to google supports .ppt files, but works with .pptx if you have a .ppt file open whenever you run the .js file that the .hta program uses.


What I need to learn how to do is 2 fold:

1. (Most Importantly) - modify the .js file to open each .ppt file using the 'source formatting' option like you'd have if you were manually pasting a copy. Each of my files has a different and important formatting that needs to remain in my combined file.

2. (Just an update) - modify the .js file to work properly with .pptx files like the original creator of this intended.

pptjoin.functions.js exact text [all within the .zip file on google docs]:
function $(id) {
return document.getElementById(id);
}
function init() {
window.resizeTo(500, 300);
$('step1').innerHTML = STRINGS.STEP1;
