Needs "standalone" options that can be used even if required options are not set
--------------------------------------------------------------------------------
Key: CLI-179
URL: https://issues.apache.org/jira/browse/CLI-179
Project: Commons CLI
Issue Type: Improvement
Components: Parser
Affects Versions: 1.2
Reporter: Joël Royer
it is currently impossible to have options like "help" or "version" if we also
have some required options. The parsing results in an error "Missing
parameters".
But for an "help" or "version" option, it would be usefull to display the
wanted information, even if required options are not set.
