Razor ViewEngine: How do I escape the "@" symbol?

If you are adding Twitter meta tags

and your Twitter username is, say, foobar

it should look like this

<meta name="twitter:site" content=@("@foobar")>

You have to use @@ to escape the @ symbol.

One important thing to notice is that you DO NOT need to escape the @ symbol when it exists within an email address. Razor should be smart enough to figure that out on its own.
