title: Add a new language to Visual Studio 2010 with syntax highlighting and intellisense
body: <p>I am trying to add support for a different language in Visual Studio 2010. I was hoping to add custom syntax highlighting, and have some sort of basic intellisense work with it. The language I am trying to add is 4Js Genero (a newer version of Informix-4GL). I basically just need support for the <code>.4gl</code> and .<code>per</code> file extensions that are used in Genero/4GL. Does anyone know how to do this, or can point me in the right direction?</p>
