@matthiasblaesing: so far I have been excluding template files from Rat.
They are user visible as far as I can tell and I don't believe it's good for
NetBeans to have that. Maybe there is some flag or something in the non-dev
builds that hide the licese... I have yet to see the license header disappear
when shown.---
