[Radiance-general] Newbie Install Question

[Sean Smallman]

Thanks a lot Tom!

I believe everything is working, I just need to get my files from  
class to actually check it all out.

Thanks a lot for taking the time to spell everything out, it really  
made everything easy for someone who is very new to playing around in  
the terminal.

Thanks!

-Sean
