title: How to add command line parameter dependency using JCommander?
body: <p>I am using JCommander for command line parameters parsing. I would like to add parameter dependency, but from the JCommander documentation, I am not able to find out if it is even supported. Has anyone tried it ?
  For example, java -jar Some.jar -a Foo -b Hola
  So, option -b shall only accompany with option -a.</p>
  
  <p>This is <a href="http://args4j.kohsuke.org/args4j/apidocs/org/kohsuke/args4j/Option.html#depends()" rel="nofollow">supported in args4j</a>. However, I can't use args4j because it does not support <a href="http://jcommander.org/apidocs/com/beust/jcommander/Parameter.html#names()" rel="nofollow">multiple values as JCommander</a>.</p>
  
  <p>Thanks</p>
