            5 # TODO:
            6 # * remove network access from npm ci
            7 # * use supported versions of LLVM and binaryen (current it requires git head)
            8 # * enable tests
            9 # * use the python eclass properly
           10 # * fperms +x is wrong
           11 # * fix many QA issues
