pyratemp is probably (one of) the smallest complete template-engines for Python (with less than 500 LOC). It has a very small set of special syntax in the templates. These features reduce complexity and the probability of bugs and lead to an easy-to-use and intuitive user-interface. It uses embedded Python-expressions (in a "sandbox"), is well documented, has full Unicode-support, and produces very good error-messages, which is very useful when creating new templates.
