puts "\nThank you for using our application! This script is designed to help you set your configuration action_mailer. These action_mailer are things that you will probably never need to change, though if you do, all you need to do is run this script again. If the script should fail for any reason, no changes will be saved; this prevents half-configured applications. You will need to know a few parameters, namely the action_mailer for your mail server and your CAS (Central Authentication Service) server (if you plan on using CAS.)\n\n"
puts "Note that this script saves changes to your config/environment.rb and config/initializers/login_action_mailer.rb files. If you need to manually adjust any of these settings, you can directly edit those files, though caution is advised. You can also run this script again to reconfigure. But a word of warning:if you run this script after your initial deployment, there is a possibility that you will break some aspects of your application. Your database should still be intact (so you won't lose any data), but you may run into other problems.\n\n"
puts "NOTE: After running this script, you will need to restart your server before any changes will take effect. The process for doing this varies depending on your exact deployment method. Consult your deployment instructions or ask your favorite Rails developer if you have any difficulties.\n\n"
puts "And as with all things, feel free to ask the developers if you have trouble! The original team can be contacted via our git repository at, and we'll be happy to try and answer any questions posted to the wiki or issues tracker there or emailed to us personally.\n\n"
