Remko Popma commented on HDDS-453:
----------------------------------
Picocli allows you to have both if desired:
You can declare an option as
{code}
@Option(names = {"-init", "--init"}, description = "...")
String init;
{code}
It is even possible to make the {{-init}} option a _hidden_ option so it does
not appear in the usage help message but the parser will recognize the option
to smoothen the transition and avoid backwards compatibility issues.
> om and scm should use piccoli to parse arguments
