If you are looking for a tool with a good Eclipse integration (and a nice GUI), I suggest: Eclipse Copyright Generator
This adds:
- a new Panel in the preferences (global or project based) with:
Menu > Windows > Preferences > General > Copyright. - a Menu Menu > Project > Apply Copyright…
- a realy nice Wizard with a lot of options and some default template for Open-Source licence (Apache, EPL, …)
I just tried it with eclipse 3.6 and it work fine.
There is an update site to install it:
