Google App Engine compliant variation of FreeMarker. FreeMarker is a "template engine"; a generic tool to generate text output based on templates.

There is a newer version: 2.3.33

The {@link freemarker.template.DefaultObjectWrapper default object wrapper} of FreeMarker uses
this to expose Java Beans and POJO-s to templates, but it can also be used in itself as a
better alternative {@link freemarker.template.ObjectWrapper}.

Most of the issues dealing with beans are handled by the 
{@link freemarker.ext.beans.BeansWrapper#wrap(Object)}and {@link 
freemarker.ext.beans.BeansWrapper#getStaticModels()} methods. In normal cases, 
 these are the only methods
you should use to turn an arbitrary Java object into a 
FreeMarker {@link freemarker.template.TemplateModel}. Additionally, you can manually create 
instance of any wrapper class using its constructors.
Note, however that in such cases you bypass the eventual model caching
of the wrapper.
