2 is what is it supposed to mean.  I am updating the documentation in 
that file to note the change.

On the topic of the build system I finally had time to review some of 
the changes you made and I have a few comments:

- I think we should remove the ";"'s at the end of some of the lines.  
It is not needed for python and it is probably better to have the entire 
file be consistent.
- Some of the helper methods could be moved to a separate file like 
"tools/scons-build/helpers.py" or something similar.  This could make 
the main SConstruct file a bit less intimidating.
- There is still a lot of things that could be improved but I think most 
of these owe to the fact that the variant and environment builder code I 
wrote is still very rough and undocumented.  I will see what I can do on 
this with the limited time I have right now.
