Hi!
To be able to use calcurse(1), it would be nice if abook supported
exporting the birthdays in iCalendar format. I've implemented this
and sent a merge request upstream.
As I'm not sure what's the upstream state, I'm sending it here too
in the hope that it might be mergeable in Debian regardless of the
upstream situation. Otherwise, it is just a nicer way to track the
progress. :)
Thanks,
Guillem

Subject: [PATCH] Add support for iCalendar export format
This will export the birthday data into an iCalendar formatted file,
as aspecified in RFC 5545.
