Someone was just asking for it and I had written these two plugins already some months ago,
so I'm now publishing them here.
-[`copyright.pm`](http://www.schwinge.homeip.net/~thomas/tmp/copyright.pm)
+[`copyright.pm`](http://schwinge.homeip.net/~thomas/tmp/copyright.pm)
and
-[`license.pm`](http://www.schwinge.homeip.net/~thomas/tmp/license.pm)
+[`license.pm`](http://schwinge.homeip.net/~thomas/tmp/license.pm)
Usage instructions are found inside the two plugin files.
