this sounds very interesting indeed. So far, I debugged my scripts by 
stepping through the build with a debugger (Eclipse+pydev)...or by 
"print" statements in the more simple cases. I don't know of any similar 
SConstruct parser out there, so let's hear more about your solution. ;)

Is there a repo somewhere? Then I'd take a look...
