These days I stumbled upon #vdirsyncer. I was looking for a good solution to be able to display and edit my #CalDAV calendars and to synchronize them.
Until today I used #thunderbird, because I didn't find a good terminal based tool. Then I found #khal which is pretty nice I think. Now I can test it in everyday-life 🙂
vdirsyncer can sync local calendars with servers and server to server as well. I'm very excited 🙂
