--Awesome script, simple question!--

Hello all,
I came across an awesome script that creates a dynamic booklet through which you can flip the pages in a very realistic and convincing matter.

The open source .fla can be found here:

Now I have a simple question (please pardon my actionscript ignorance):
I want the booklet to read right-to-left instead of left-to-right. This means the booklet will actually start from the last page, and users will flip it backwards.

I know this is quite simple for anyone who knows his way with actionscript.
Could you please help me?
