Thanks to the diligent efforts of Terry Mc Minn, we now have an updated list of manual page entries on the Radiance website, accessible via the usual means from:
http://radsite.lbl.gov/radiance/refer/
For jollies, I added a link where you can download all the HTML pages if you prefer to have a local copy.
I have updated the abbreviated and comprehensive lists as well as the PDF of all man pages, so everything _should_ be there. If you spot an omission, please write to me directly and I'll see what I can do.
