StringTemplate templating engine for Java

 StringTemplate is a Java template engine for generating source code,
 web pages, emails, or any other formatted text output. StringTemplate
 is particularly good at multi-targeted code generators, multiple site
 skins, and internationalization/localization.
 .
 Its distinguishing characteristic is that unlike other engines,
 it strictly enforces model-view separation. Strict separation makes websites
 and code generators more flexible and maintainable; it also provides
 an excellent defense against malicious template authors.
