actually that's used by tcl NVIZ so still in use. wx NVIZ is not yet
to the point where it can replace the tcl version.
(btw, we should rename visualization/nviz2/ to be wxNViz or something;
the tcl version is already version 2.2)

I added a new lib/external/README.license file to explain things.
AFAICT the SUBMITTING file and RFCs do not require adjustment.
