+Inspired by ctemplate, Mustache is a framework-agnostic way to render
+logic-free views.
+
+As ctemplates says, "It emphasizes separating logic from presentation:
+it is impossible to embed application logic in this template
+language.
+
+Think of Mustache as a replacement for your views. Instead of views
+consisting of ERB or HAML with random helpers and arbitrary logic,
+your views are broken into two parts: a Ruby class and an HTML
+template.
