Hi list! I decided to give org-contacts a try. Since there doesn't seem to be a facility for importing contacts in vcard format, I wrote a little Python script for that. Perhaps someone on this list finds it useful.
https://gist.github.com/tmalsburg/9747104 The script uses the Python package vobject for parsing vcard files. On Debian-like systems this package is available as python-vobject. I tested the script with contacts exported from Apple's iCloud service and that worked well. However, the vcard format is somewhat messy and I don't know what happens with vcard files generated in other contact managers. Use at your own risk. If there's interest, I might migrate the script to a proper Github repository and develop it further, i.e., merge your pull-requests ;-) Titus
