The purpose of Antlr package in Visual Studio 2013 ASP.NET project

antlrasp.netnuget-packagevisual-studio-2013

The ASP.NET (web forms) project template in Visual Studio 2013 includes several packages. I'm trying to figure out which ones are essential (may need to create a separate question for this). The post at http://blogs.msdn.com/b/webdev/archive/2013/10/16/asp-net-features-in-new-project-templates-in-visual-studio-2013.aspx explains the purpose of some of them, but I cannot figure out which need Antlr serves. Can someone clarify?

It is a transitive dependency declared in the WebGrease package, where it is used for a CSS lexer and parser.
