This revision now requires changes to proceed.

I've tried using the patch, and I got blocked at the following: CTU options are only exposed when one goes through `analyze-build` frontend, which requires `compile_commands.json` to be present. I've used `libear` to generate `compile_commands.json`, but the generated JSON does not contain the `command` field, which causes `@require` before `run` to die (also, due to the passing style this error was unnecessarily difficult to debug).
So could you write a short documentation somewhere how all pieces fit together? What entry point should be used, what should people do who don't have a build system-generated `compile_commands.json`etc. etc.
