Problem: build systems are horrid

[hintjens]

I've been playing with GYP which turns out to be stupidly simple. For instance there is no configure phase. You know what platforms you support, and you provide the macros that platform needs. I look at project.xml -> configure.ac -> configure -> make -> sh and I can't help wonder if there's not a much simpler way.

Solution: add shell target. This would generate shell scripts (bash, Windows batch) to compile/link a project.
