;;; Commentary:
;; This library provides an interface to the ecomplete package as
;; an EUDC data source.
;;; Usage:
;; No setup is required, since there is an entry for this backend
;; in `eudc-server-hotlist' by default.
;;
;; For example, if your `ecomplete-database-file' (typically
;; ~/.emacs.d/ecompleterc) contains:
;;
;; ((mail ("larsi@gnus.org" 38154 1516109510 "Lars <larsi@ecomplete.org>")))
;;
;; Then:
;;
;; C-x m lars C-u M-x eudc-expand-try-all RET
;;
;; should expand the email address into the To: field of the new
;; message.
;;; Code:
(require 'eudc)
(require 'ecomplete)
(require 'mail-parse)
(defvar eudc-ecomplete-attributes-translation-alist
'((email . mail))
"See `eudc-protocol-attributes-translation-alist'.
The back-end-specific attribute names are used as the \"type\" of
entry when searching, and they must hence match the types you use
in your ecompleterc database file.")
