Good question. Can you give me an example.
When I created this there was much debate over whether
to make this a module or a class. IIRC, class was used
becuase it was thought that any mixed in functionality
should really go in its own class to have SOI. The app
class is really just to handle the interface with the user.
So, a standard app would look like so:

  class MyApp < CommandLine::Application
    def initialize
    end
    def main
      # keep SOI
      MyBigWorkingClass.new(@option_data)
    end
  end

No. CommandLine has its own (more powerful) parser called
CommandLine::OptionParser.
