Blender 2.4x Apply Deformation script in 2.53?

I was wondering how to use blender’s previous “Apply Deformation” script with Blender 2.53. I think I found the .py file online, but when I try to install it into the Add-ons section, absolutely nothing happens. Any advice?:confused:

Give us(me) a link to the source (than maybe I could help making it work [again])

I found the script he was talking about, I was wondering if you could help me updating it for the most recent blender version
