Add to Calendar Date Augmenter

This module provides links to add an event to a calendar, without relying on external dependencies or libraries. This module leverages the Date Augmenter API to provide a plugin that will add these links to another formatter, instead of forcing you to choose a formatter that only adds add to calendar links. So you can use a feature-rich formatter (providing it also supports this API) and add the links to its output.

Because the Smart Date module supports the Date Augmenter API as well as recurring dates, using this combination allows your site to provide links that will add the entire recurring series to a calendar.
