There are two approaches:

- FreeMarker does NOT assume that the templates are real files.
  Write a custom freemarker.cache.TemplateLoader,
  (http://freemarker.org/docs/api/freemarker/cache/TemplateLoader.html)
  and plug it into the Configuration as the "template loader" setting,
  and that's it.

- You can create Template objects from whatever string-like value by
  using the Template(java.lang.String name, java.io.Reader reader, Configuration cfg)
  constructor. However, note that in this case solving template caching is up
  to you. Also note that dependencies will be loaded through the "cfg",
  using the "name" to deduce the base path.

- A solution that is kind of between the above two:
  Use freemarker.cache.StringTemplateLoader.
