/**
 * Read, parse and handle everything related with the templates.

 * A web template system uses a template processor to combine web templates to
 * form finished web pages, possibly using some data source to customize the
 * pages or present a large amount of content on similar-looking pages. It is a
 * web publishing tool present in content management systems, web application
 * frameworks, and HTML editors.
 *
 * Web templates can be used like the template of a form letter to either
 * generate a large number of "static" (unchanging) web pages in advance, or to
 * produce "dynamic" web pages on demand.
