Histone is a powerful and flexible template engine used to produce HTML code as well as any other text formats. Histone can be run on the client (JavaScript) as well as server (Java, PHP) side without modifying your templates. Its built-in extensions API allows you to add your own methods and attributes that are specific to your project. The resulting templates have clean and intuitive syntax, you can store them in either original or "optimized" form that will not require parsing, depending on whether or not you need an extra performance.
