From CA Smith:
No more output limitations for iCal! This indispensable utility will list all Events from a chosen list of iCal calendars within a specified date range. The list is created and placed into the clipboard as either plain text, or (X)HTML formatted text, and can thus be pasted into any word processing or text editing software you like. Calendar and Event data is drawn directly from the Calendar Store database, therefore, iCal need not be running to use this application. The unbelievably simple interface will have you more organized moments after downloading!Please visit the Web Site to view the complete Help Book, detailed screenshots, and short video demonstrations.
