NAME
Template::Toolkit - Template Processing System

Introduction
The Template Toolkit is a collection of Perl modules which implement a fast, flexible,
powerful and extensible template processing system.

It is "input-agnostic" and can be used equally well for processing any kind of text
documents: HTML, XML, CSS, Javascript, Perl code, plain text, and so on. However, it is
most often used for generating static and dynamic web content, so that's what we'll focus
on here.

Although the Template Toolkit is written in Perl, you don't need to be a Perl programmer
to use it. It was designed to allow non-programmers to easily create and maintain
template-based web sites without having to mess around writing Perl code or going crazy
with cut-n-paste.

However, the Template Toolkit is also designed to be extremely flexible and extensible. If
you are a Perl programmer, or know someone who is, then you can easily hook the Template
Toolkit into your existing code, data, databases and web applications. Furthermore, you
can easily extend the Template Toolkit through the use of its plugin mechanism and other
developer APIs.

Whatever context you use it in, the primary purpose of the Template Toolkit is to allow
you to create a clear separation between the presentation elements of your web site and
everything else.

If you're generating static web pages, then you can use it to separate the commonly
repeated user interface elements on each page (headers, menus, footers, etc.) from the
core content. If you're generating dynamic web pages for the front end of a web
application, then you'll also be using it to keep the back-end Perl code entirely separate
from the front-end HTML templates. Either way, a clear separation of concerns is what
allow you to concentrate on one thing at a time without the other things getting in your
way. And that's what the Template Toolkit is all about.

Documentation
The documentation for the Template Toolkit is organised into five sections.

The Template::Manual contains detailed information about using the Template Toolkit. It
gives examples of its use and includes a full reference of the template language,
configuration options, filters, plugins and other component parts.

The Template::Modules page lists the Perl modules that comprise the Template Toolkit. It
gives a brief explanation of what each of them does, and provides a link to the complete
documentation for each module for further information. If you're a Perl programmer looking
to use the Template Toolkit from your Perl programs then this section is likely to be of
interest.

Most, if not all of the information you need to call the Template Toolkit from Perl is in
the documentation for the Template module. You only really need to start thinking about
the other modules if you want to extend or modify the Template Toolkit in some way, or if
you're interested in looking under the hood to see how it all works.

The documentation for each module is embedded as POD in each module, so you can always use
"perldoc" from the command line to read a module's documentation. e.g.

$ perldoc Template
$ perldoc Template::Context
...etc...

It's worth noting that all the other documentation, including the user manual is available
as POD. e.g.

$ perldoc Template::Manual
$ perldoc Template::Manual::Config
...etc...

The Template::Tools section contains the documentation for Template::Tools::tpage and
Template::Tools::ttree. These are two command line programs that are distributed with the
Template Toolkit. tpage is used to process a single template file, ttree for processing
entire directories of template files.

The Template::Tutorial section contains two introductory tutorials on using the Template
Toolkit. The first is Template::Tutorial::Web on generating web content. The second is
Template::Tutorial::Datafile on using the Template Toolkit to generate other data formats
including XML.

The final section of the manual is Template::FAQ which contains answers to some of the
Frequently Asked Questions about the Template Toolkit.

You can read the documentation in HTML format either online at the Template Toolkit web
site, <http://template-toolkit.org/>, or by downloading the HTML version of the
documentation from <http://template-toolkit.org/download/index.html#html_docs> and
unpacking it on your local machine.
