If you want to make a code change and you want to allow many people to 
use it without much hassle, then you want to distribute as little as 
possible, usually only the viewer executable, and let others just drop 
it into the existing installation.  This means the stable version and 
the release candidates and an occasional First Look.

I have never built from the trunk and I don't see any reason I would 
want to. :-)
