The Template Toolkit is a fast, flexible and highly extensible template processing system. It is Free (in both senses: free beer and free speech), Open Source software and runs on virtually every modern operating system known to man. It is mature, reliable and well documented, and is used to generate content for countless web sites ranging from the very small to the very large.

It is written in the Perl programming language but you don't need to know any Perl to use it. In fact, it was specifically created to allow web designers and developers to concentrate on generating web pages without getting bogged down in programming matters. We call this a "Clear Separation of Concerns" and it makes the whole processes of building, updating and maintaining a web site or web application significantly easier.
