I would propose to use a DH Sequence rather than a build system. Mainly
the greatest advantage of build systems are that they are auto-chosen,
but this is disabled for third party build systems, so...

Personally I do have some experience, but I have quite a few things on
my plate. I fear it may be a while before I can dedicate myself to this
