I've beat this drum before, and I'll beat it again here. The build configuration for every large project eventually becomes turing complete (requiring loops, conditionals, subroutines, what have you). Why is it then, that every new build tool that comes to town is declarative? Just give me a nice library full of handy build functions and I can write a build script in fewer lines than any build tool configuration -- and be more readable to boot.
