[Radiance-general] Experimental Radiance build scripts

[R Fritz]

I have written a set of scons scripts which build Radiance on Linux,  
Windows (using MSVC), and Mac OS X. The scripts are simple and  
generally follow the library model used in makeall. They work with the  
current Radiance head and are very alpha--the scripts do not install  
the built files and there are other limitations--but I think they  
might be interesting for experimentation. If anyone is interested in  
experimenting with them, I would be delighted to share them.
