Need src of iutil.prestashop-modifications.js

[Frank84]

Hi all.

At the front office I'd like to use jquery.tools library. Tabs in particular
http://flowplayer.org/tools/

I found that Tabs forces an error in jQuery "too much recursion". But jquery.tools is proven library so I tried to find what script of Presta conflicts. It is iutil.prestashop-modifications.js Without it fancy add-to-cart animation doesn't work. Where can I find source code of iutil with modifications what was 16 september 2008 according to comments in this file?

Thanks in advance.
