I just love Google they make life so easy! Say you wanted to write a program that automatically retrieves text from your emails and automatically sends reply mails according to that text.
You would fantasize `wouldn't it be great if I could just go to some website, maybe a good name for it would be `script.google.com', and just start writing something that looks like gmail and I would get suggestions about script commands that can do what I want'
Well , this fantasy is a reality
