My rails 3 app receives emails. Some of them are plain text. When the app displays them to the user I want them to be properly formatted. In other word I want to encode plain text into html. For example: "Hello\n\nHello" => HelloHello (or something like it).
Of course I can write my own 4 lines of code but I am sure those 4 lines have already be written, tested and wrapped in some nice method call.
