I started from the 78ec8e commit then cherry-picked and squashed commits that have been done in master since then, except the bad commits that overwrote the tree (in master) with the tree in maint. This commit also bumps the version number to 7.8.06. The only "fix" that was made between 78ec8e and the previous commit is e0072f which has been reported to break stuff.

;; 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.
