What is the purpose of Antlr package in Visual Studio 2013 ASP.NET project?

antlr, asp.net, nuget-package, visual-studio-2013

Solution

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

Problem

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?
