A calendar module for Roundcube ------------------------------- This plugin currently supports a local database as well as a Kolab groupware server as backends for calendar and event storage. For both drivers, some initialization of the local database is necessary. To do so, execute the SQL commands in drivers//SQL/.initial.sql The client-side calendar UI relies on the "fullcalendar" project by Adam Arshaw with extensions made for the use in Roundcube. All changes are published in an official fork at https://github.com/roundcube/fullcalendar For some general calendar-based operations such as alarms handling or iCal parsing/exporting this plugins requires the `libcalendaring` plugin which is also part of the Kolab Roundcube Plugins repository. Make sure that plugin is installed and configured correctly. For recurring event computation, some utility classes from the Horde project are used. They are packaged in a slightly modified version with this plugin. IMPORTANT --------- The calendar module makes heavy use of PHP's DateTime as well as DateInterval classes. The latter one requires at least PHP 5.3.0 to run.
