Usage:  origen pl
        origen pl [plugin name]
        origen pl [CMD] [options]

Quickstart Examples:
  origen pl                             # Displays the current plugin
  origen pl added                       # Lists the included plugins
  origen pl [plugin_name]               # Sets the specified plugin as current plugin
  origen pl reset                       # Resets the current plugin to none

The following commands are available:

  added                               Displays all plugins that are currently included in this app locally

The following options are available:
  EOT
  opts.on('-d', '--debugger', 'Enable the debugger') {  options[:debugger] = true }
  opts.on('-h', '--help', 'Show this message') { puts opts; exit }
end
