    <p>Hello,</p>
    <p>A quick note about that 'make.md' document: it's meant as a quick
      reference/cheatsheet (hence the _very_ lightweight format) for
      people familiar with the make build system. Hadrian's README [1]
      is a better place to start from in general and in fact answers or
      points to documents that answer some of your questions. I would
      perhaps recommend that you (and others) wander through that
      document and any other doc that seems relevant to your
      interests/workflow (e.g testsuite.md, user-settings.md in your
      case)<br>
    </p>
    <p>Hadrian is however currently lacking some knobs that are needed
      to support some of the things you're asking about. None of this
      implies a lot of work and they're all on my TODO. I will certainly
      make sure to post an update once this is taken care of, in
      addition to augmenting the relevant documents of course. For
      instance, we don't have a 'validate' rule at the moment, but we've
      now got all the pieces we need to write it.</p>
    <p>Once I get around to adding those knobs, I'll make sure that all
      your questions are answered in the documentation.</p>
    <p>Thanks for your initial feedback on this document!<br>
    </p>
