/*
Plugin Name: WP Events Calendar
Plugin URI: http://www.wp-eventscalendar.com
Description: There are options under the widget options to specify the view of the calendar in the sidebar. The widget can be a list for upcoming events or a calendar. If you do not have a widget ready theme then you can place `&lt;?php SidebarEventsCalendar();?&gt;`, or `&lt;?php SidebarEventsList();?&gt;` for an event list, in the sidebar.php file of your theme. If you want to display a large calendar in a post or a page, simply place `[events-calendar-large]` in the html of the post or page. Make sure to leave off the quotes.
Version: 6.7.8
