Elek, Marton commented on HDDS-190:
-----------------------------------
I prefer to fix it in a generic way as it's required for HDDS-174 as well. And
as we have not so good documentation at least we need proper help at the
console output...
Sorry to hijack, I just uploaded a bigger patch to change the argument parsing
to use picocli. All the unit tests and acceptance tests are passed.
