Update: Code Search Sitemaps are no longer supported. More information.

The Sitemaps team is continuing its trend of extending the Sitemap Protocol for specific products and content types. Our latest work with the Google Code Search team now enables you to create Sitemaps that contain information about public source code you host and would like to include in Code Search. There's more information about this new functionality on the Google Code blog. If you're eager to get going, take a look at our Help Center documentation, create a Code Search Sitemap, sign into Google Webmaster Tools, and submit a Sitemap for Code Search!
