$ bundle install

    create  config/cucumber.yml
    create  script/cucumber
     chmod  script/cucumber
    create  features/step_definitions
    create  features/support
    create  features/support/env.rb
     exist  lib/tasks
    create  lib/tasks/cucumber.rake
      gsub  config/database.yml
      gsub  config/database.yml
     force  config/database.yml

or alternatively, you can check the options before executing the installation script.
