I went through the website, and still don't really know what this symphony is supposed to be. Yes, I understand it's a "Framework", and I assume this to describe a kind of library or IDE for php based web design, but for what? That is rather cloudy. The web site reads like ads for tampons: "you can swim with it, play tennis with it, climb mountains with it."

I really miss a meaningful description of what this is supposed to be.
