Clone of Facebook Share Script

I am trying to clone the functionality of this site: [login to view URL] You'll notice the JavaScript files are publicly viewable, and many are open source. I have copied everything I could and installed it here: [login to view URL] It looks like in there is a reference to the following files in [login to view URL] ( /js/[login to view URL] ) [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] these are closed source files.. so.. it seems the easiest way to clone this would be to figure out what functionality / output is required of these files, and create new versions of them. alternately, if someone has something similar or could create something from scratch that would have the functionality of the above site, I'd be open to looking at that.
