;; USAGE NOTE
|
|
;;
|
|
;; You will need to configure mairix first, which involves setting up your
|
|
;; .mairixrc in your home directory. Once it is working, you should set up
|
|
;; your way to display results in your favorite way -- usually a MUA.
|
|
;; Currently gnus and mutt are supported.
|
|
;;
|
|
;; After both steps are done, all you should need to hook mairix, org
|
|
;; and your MUA together is to do (require 'org-mairix) in your
|
|
;; startup file. Everything can then be configured normally through
|
|
;; Emacs customisation.
