ICalManager holds functions related to ICalendar management. Important role plays configuration - almost all data sources are defined via SysConfig settings. Data sources are related to the TicketObject (dynamic fields, ticket owner, customer etc.). ICalManager supports multiple configuration profiles, thus it is possible to define different sources for single person and team. CGI script 'ical.pl' provides a front-end functionality - it loads specified arguments and creates ICal file according to configuration. Resulting file is streamed as attachment - this means user can set up internet calendar in MS Outloook or other application (internet calendar is set as a link containing arguments for ical.pl).
