The comment is slightly wrong, yes. For correct results you need to
either:
1. inherit module (not module-base), which does:
addtask make_scripts after do_patch before do_compile
and will ensure that the scripts are built before your module is
compiled without you needing to do anything else. Or...
2. inherit module-base and arrange to call do_make_scripts() explicitly
from your own recipe.
