  === Built-in Help Subcommand
  From 3.0, picocli provides a `help` subcommand (`picocli.CommandLine.HelpCommand`) that can be installed as a subcommand on any application command to provide usage help for the parent command or sibling subcommands. For example:
  
  [source,java]

  For example, the following command prints usage help for a subcommand:
  [source,bash]
  ----
  myapp help subcommand

  To print usage help for the main command:
  [source,bash]
  ----
  myapp help
