Mozilla Sunbird is a full blown enterprise ready calendar and task
management application, using Mozilla XUL framework. It supports local
and remote calendar using CalDAV or WCAP protocols, and subscription
to iCal/.ics invitations.
Lightning provides the calendar/task management extension for Mozilla
Thunderbird.
Port heavily based on mail/mozilla-thunderbird.
