Note that you can also use your own TemplateDirectiveModel for this,
like

<@my.pack>
  <#list ...>
    ...
  </#list>
</@my.pack>

however that will act on the output of the template, which means
runtime overhead. But sometimes it's more appropriate...

cfg.setDirectoryForTemplateLoading is just a convenient shorthand for
cfg.setTemplateLoader(new FileTemplateLoader(theDir)), so it replaces
your template loader.
