It's completely up to the framework that embeds FreeMarker...
FreeMarker doesn't interfere with this business. So if the embedding
framework doesn't provide a FreeMarker directive for this (something
like <@foo.log "Till here's OK" />), you will have to provide a such
directive yourself: implement TemplateDirectiveModel, and either put
it onto the data-model (even with config.setSharedVariable(...), if
you can access the freemarker.template.Configuration object at its
initialization), or put it into your application-specific
#import/#include file with <#assign log =
"com.example.MyLoggerDirective"?new()>
