Google Page Rank Script

I was searching on the internet for a page rank script but couldn't find one -- but I found one that returns the checksum of a website, so I decided to make a modification of it that would query google and return the page rank. For those who do not know what page rank is, it is the algorithm in which Google has created to rank pages and is one of the many factors used in determining search engine placement or serps for short. This script is one of the only available ones for download I'm sure that is open for users to view the source.
