• entity Create new entity -> entity Creates new entity

• Not clear how to execute screen commands:

  screen      Screen related commands
    Usage: screen [options]       [command] [command options]
      Commands:
        custom      Creates new screen
          Usage: custom [options]
  
        extend      Extends login and main screens

          Usage: browse [options]

  Can we add screen to usage examples and remove Usage: screen [options] [command] [command options] line? For example:

        custom      Creates new screen
          Usage: screen custom [options]

Can we add screen to usage examples and remove Usage: screen [options] [command] [command options] line?

For now, the help message is completely generated by jcommander, and it is hardly possible to influence its structure. I suggest not to change this until Release 1.0.
