FreeMarker is a "template engine"; a generic tool to
generate text output (anything from HTML or RTF to
autogenerated source code) based on templates.
FreeMarker is designed to be practical for the generation
of HTML Web pages, particularly by servlet-based applications
following the MVC (Model View Controller) pattern.
Although FreeMarker has some programming capabilities,
it is not a full-blown programming language like PHP. Instead,
Java programs prepare the data to be displayed, and FreeMarker
just generates textual pages that display the prepared data
using templates.
FreeMarker is not a Web application framework. It is suitable
for a component in a Web application framework, but the
FreeMarker engine itself knows nothing about HTTP or servlets.
