;;; Commentary:
|
|
|
|
;; This is an interface to the mairix mail search engine. Mairix is
|
|
;; written by Richard Curnow and is licensed under the GPL. See the
|
|
;; home page for details:
|
|
;;
|
|
;; http://www.rpcurnow.force9.co.uk/mairix/
|
|
;;
|
|
;; Features of mairix.el:
|
|
;;
|
|
;; * Query mairix with a search term.
|
|
;; * Currently supported Emacs mail programs: RMail, Gnus (mbox only),
|
|
;; and VM.
|
|
;; * Generate search queries using graphical widgets.
|
|
;; * Generate search queries based on currently displayed mail.
|
|
;; * Save regularly used searches in your .emacs customize section.
|
|
;; * Major mode for viewing, editing and querying saved searches.
|
|
;; * Update mairix database.
|
|
;;
|
|
;; Please note: There are currently no pre-defined key bindings, since
|
|
;; I guess these would depend on the used mail program. See the docs
|
|
;; for an overview of the provided interactive functions.
|
|
;;
|
|
;; Attention Gnus users: If you use Gnus with maildir or nnml, you
|
|
;; should use the native Gnus back end nnmairix.el instead, since it
|
|
;; has more features and is better integrated with Gnus. This
|
|
;; interface is essentially a stripped down version of nnmairix.el.
|
|
;;
|
|
;; Currently, RMail, Gnus (with mbox files), and VM are supported as
|
|
;; mail programs, but it is pretty easy to interface it with other
|
|
;; ones as well. Please see the docs and the source for details.
|
|
;; In a nutshell: include your favourite mail program in
|
|
;; `mairix-mail-program' and write functions for
|
|
;; `mairix-display-functions' and `mairix-get-mail-header-functions'.
|
|
;; If you have written such functions for your Emacs mail program of
|
|
;; choice, please let me know, so that I can eventually include them
|
|
;; in future version of mairix.el.
|
|

|
;; 07/28/2008: version 0.2. Added VM interface, written by Ulrich
