The Template Toolkit is a collection of modules that implements a fast, flexible, powerful, and extensible template processing system. It was originally designed for generating dynamic web content, but it can be used equally well for processing any other kind of text-based documents (HTML, XML, POD, PostScript, LaTeX, etc.).

It can be used as a standalone Perl module or embedded within an Apache/mod_perl server for generating highly configurable dynamic web content. A number of Perl scripts are also provided that can greatly simplify the process of creating and managing static web content and other offline document systems.

The Apache::Template module provides a simple mod_perl interface to the Template Toolkit.

Available from CPAN. It's covered in Appendix D and at http://tt2.org/.
