module RailsAppGenerator
  # Option for the rails generator
  #
  # This class maps closely (but not exactly) to Thor's options
  # The pattern is not exactly the same, it is easy to map the options
  # you need from other generators such as: railties/lib/rails/generators/app_base.rb
  #
  # @example
  # class_option    :skip_git, type: :boolean, default: false, desc: "Skip .gitignore file"
  # becomes
  # register_option :skip_git, type: :boolean, default: false, desc: "Skip .gitignore file"
