[Tfug] Any recommendations for address management?

[Glen Pfeiffer]

I've recently switched to Mutt for email and one thing I've not 
yet implemented is my email address book.

I was using the Thunderbird/Icedove Address Book which allows for 
much more than just name and email address. I included things 
such as residential address, phone numbers, etc. I want to 
migrate all this data into another storage format that I can 
access from Mutt. LDAP seems to be the most obvious answer but I 
want to consider other options because I don't really like LDAP. 
I want a format that has a very stable future so I do not need to 
migrate this data again.

Any recommendations?
