Do you want to test that runtest is working with pipe?
I considered anything but shell script with getopt parameters a bit strange and
thought it'd be removed in new shell runner. But obviously you want to keep it.

But in case of failure script don't detect it. e.g.:

echo "SUCCESS" | cat /asdf
cat: /asdf: No such file or directory

=> there is no TFAIL/TBROK/TCONF. Not sure if all users check exit status (which
they should now, because that is the only common thing so far).

Kind regards,
Petr
