addressbook2pine is a utility that allows you to sync your OS X address book with pine's addressbook. Simply launch addressbook2pine and it will process all of your contacts in your address book and create a tab delimited file readable by pine. A prompt will ask you where you wish to save the new pine-readable .addressbook file.
