The next two commands do the same:

make -C test_dir test_name.pid
make -C test_dir test_name.out

If you want to have this functionality in our tree, I would like to have
it in zdtm.sh. For example your script is not able to execute test cases
in a new set of namespaces, but zdtm.sh can do that.

Thanks.
