Google introduced a new robots.txt tool
 

The Google Sitemaps team just introduced a new robots.txt tool into Sitemaps. The robots.txt file is one of the easiest things for a webmaster to make a mistake on. Brett Tabke’s Search Engine World has a great robots.txt tutorial and even a robots.txt validator.

How is it different from standars Robots.txt

As per my idea that each search engine has different method to use robots.txt

Google permits wildcards (*) and the “Allow:” directive, so google has its own new robots.txt guidelines for webmaster so that there will be no mistake by webmasters.
