New User Agent for News

Today we are announcing a new user agent for robots.txt called Googlebot-News that gives publishers even more control over their content.
Site owners can just add Googlebot-News specific directives to their robots.txt file. Similar to the Googlebot and Googlebot-Image user agents, the new Googlebot-News user agent can be used to specify which pages of a website should be crawled and ultimately appear in Google News.
Include pages in Google web search, but not in News:
User-agent: Googlebot
Disallow:

User-agent: Googlebot-News
Disallow: /
