Event Calendar Snippet Markup (works in Revo 2.0.8, not in 2.1.5)

<?php
/**
 * @name EasyEvents_ListMini
 * @package Easy Events
 *
 * This snippet does all the processing necessary to load a mini calendar and
 * the event list/details on a page.
 *
 * Snippet parameters
 *
 * nodes (REQUIRED)
 * A single document id, or a string of comma separated document IDs that serve
 * as starting points under which events will be searched. You must have at
 * least one node.
 *
 * calHolder, listHolder (Optional)
 * These are the placeholder names you'll use to load the calendar and
 * list/details respectively. If not specified, the default from the config file
 * will be used. The only time you might want to specify this explicitly is when
 * you have more than one mini calendar and list/details on a page and you need
 * to separate them.
 *
 * calDiv, listDiv (Optional)
 * These are the divs in which the placeholders (above) reside. Like the
 * placeholders, these will default to the config file setting and don't
 * generally need to be defined.
