digestive-functors-0.7.1.5: A practical formlet library

Digestive functors is a library inspired by formlets:

It is intended to be an improvement of the Haskell formlets library, with as main advantages:

• better error handling, so a web page can display input errors right next to the corresponding fields;
• the ability to easily add <label> elements;
• separation of the validation model and the HTML output.
