A web based Calendar/Scheduler that can be used for scheduling meetings, events, vacations, menus, or just about anything else. The browser interface provides viewing, editing and administration of the calendar. iCal is not a CGI program that requires an existing Web Server environment. A small dedicated Web Server is built into iCal. When you start the iCal program you are also starting a Web Server. Because of this built in server, you can immediately have your calendar up and running, and available to anyone on your network. Since you can specify the port number of the iCal Server, it can co-exist with any other Web Server you may have running on your system. Any number of calendarscan be created. A security system defines passwords for who is permitted to make changes to the calendars.
