```ruby
module Troo
  module CLI
    class ThorFixes < Thor
      def self.banner(command, namespace = nil, subcommand = false)
        if subcommand
          "#{basename} #{@package_name} #{command.usage}"
        else
          "#{basename}#{@package_name} #{command.usage}"
        end
      end
    end
  end
end
```
