<p>Hello,<span style="font-size:11.0pt"><o:p></o:p></span></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)<o:p></o:p></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.<o:p></o:p></p>
<p>Once I get around to adding those knobs, I'll make sure that all your questions are answered in the documentation.<o:p></o:p></p>
<p>Thanks for your initial feedback on this document!<o:p></o:p></p>
