Writing gyp files directly still doesn't solve the "explicitly
specifying the LLVM domain specific component organization problem".
Gyp is written in Python, and while I haven't looked at the code, I
imagine it could be tied in tightly (i.e., programmatically) if that
proved interesting -- that would give us all the features of gyp with
a concise LLVM specific component description syntax.

I don't generally believe it is tractable to generate great project
files for a specific project from a generic configuration language.
