'TUP' is the fastest build system of the all? I believe many build 
systems leverage or imitate what TUP does. I've read that for hand 
crafting a specific build system, TUP is the most fundamental of the 
building blocks. Here are a few links, there are many for your perusal::

I think TUP would really shine in a build system for embedded and 
otherwise constrained build environments (limited resources) but I have 
not vetted that theory out, as I usually lean on others with greater 
depth of understanding in such matters. Still, from what I read, TUP 
warrants monitoring as new code contributions keep moving this blazingly 
fast build system tool forward. If others have first hand experience 
with TUP, I'd very much like to read about their comments and 
experiences with TUP.
