+ * A simple iCal parser. Should take care of most stuff for ya
+ * http://github.com/fangel/SG-iCalendar
+ *
+ * Roadmap:
+ *  * Finish FREQUENCY-parsing.
+ *  * Add API for recurring events
+ *
+ * A simple example:
+ * <?php
+ * $ical = new SG_iCalReader("http://example.com/calendar.ics");
+ * foreach( $ical->getEvents() As $event ) {
+ *   // Do stuff with the event $event
+ * }
+ * ?>
