small but fast and easy to use stand-alone template engine

 Jinja provides a Django-like non-XML syntax and compiles templates
 into executable Python code. It's basically a combination of Django templates
 and Python code.
 .
 Philosophy: application logic is for the controller but don't try to make the
 life for the template designer too hard by giving him too few functionality.
 .
 Features:
  * Simple API.
  * Extremely lightweight.
  * The whole engine is completely sandboxed. A template designer won't be able
    to modify application data or execute dangerous code
  * You can use nearly every Python expression. Not supported are the binary
    operators and list comprehensions / generator expressions.
  * Uses the same concept for inheritance Django uses. It's very powerful
    and easy to understand.
  * Provides so called macros that allow you to put often used template
    snippets into callable blocks
  * Designer friendly. Jinja simplifies many things for a template designer.
    Loops can be used in a recursive way, filters are available to format
    values, loops know about their iteration etc.
  * Dynamic syntax. You don't like the Django block syntax? You can override
    the syntax elements on environment initialisation. It's no problem to use
    ASP/PHP/Ruby syntax, html comments for blocks etc.
