I found the beginning of the tutorial very clear. I really liked 
that it can produce a png of the build graph. I also liked the 
Lua build description for DMD. Much more legible than the make 
file.

However, once I got to the "Going Meta: Building the Build 
Description" section of the tutorial, I got a little confused.

I found it a little weird that the json output towards the end of 
the tutorial don't always match up. Like, where did the .h files 
go from the inputs? (I get that they aren't needed for running 
gcc, but you should mention that) Why is it displaying cc instead 
of gcc? I just feel like you might be able to split things up a 
little and provide a few more details. Like, this is how to do a 
base version, then say this is how you can customize what is 
displayed. Also, it's a little terse on the details of things 
like what the cc.binary is doing. Always err on the side of 
explaining things too much rather than too little, IMO.
