You're right. I pushed the commit (no matter the state of the code, bashisms
should be fixed).

Sorry for pointing to runltp-ng, which might not be yet ready for using/testing.
I meant that more like info for users, not to waste time with something
which should have been either rewritten from scratch or replaced.

I haven't looked into the code myself (planning to), but it's really promising :).

Kind regards,
