Collect your contacts with the Blackbook Gem
Dave Myron of Contentfree wrote a great Gem that he’s
named Blackbook. The Gem is hosted in the
Contentfree collection on Ruby
Forge. Blackbook imports
contacts from a number of sources and currently supports AOL Mail, GMail, Hotmail,
Yahoo! Mail, and contacts from CSV file. Blackbook exports the contacts that have
been collected as XML and VCard formatted text or as an Array of Hashes
with :name and :email keys.
