Description:
Sync personal information data via SyncML/CalDAV/CardDAV (GTK+ GUI)
SyncEvolution synchronizes contact, calendar and task items via SyncML and CalDAV/CardDAV with other servers or devices. It uses the Evolution Data Server to sync PIM data in Evolution, but a plain file storage is also supported. Data exchange can happen via HTTP(S) and Bluetooth. Full, one-way and incremental synchronization of items are supported. SyncEvolution can act as a SyncML/DAV client and SyncML server. . This package provides a GTK+ graphical user interface.
