This package uses the Notmuch database to output the names and e-mail addresses of the people you have exchanged e-mails with, most used ones first. This works neatly as address completer for the Notmuch Emacs interface.

The program works by invoking from a shell. The only argument it takes is a string, which is searched for in the e-mail addresses contained in the headers of the messages indexed by Notmuch.
