[Radiance-general] CIE version in gensky

[Andrew McNeil]

The old radiance websites still exist, if you know how to get to them:
http://radsite.lbl.gov/radiance/
https://www.radiance-online.org:447/
Your browser will probably complain about the security of the second one,
and if you have an overzealous IT department you might not be able to use
port 447
