+ * This script extracts event data from a table on a webpage and generates an iCalendar (.ics) file for download.
+ * It looks for a table with specific headers ('event', 'date', 'venue', 'address'), parses the event details,
+ * and then creates an iCalendar file with the extracted event information. The file is then automatically
+ * downloaded to the user's device.
