;;; Commentary:
|
|
;; This package provides a common interface to query directory servers using
|
|
;; different protocols such as LDAP, CCSO PH/QI or BBDB. Queries can be
|
|
;; made through an interactive form or inline. Inline query strings in
|
|
;; buffers are expanded with appropriately formatted query results
|
|
;; (especially used to expand email addresses in message buffers). EUDC
|
|
;; also interfaces with the BBDB package to let you register query results
|
|
;; into your own BBDB database.
|
|
|
|
;;; Usage:
|
|
;; EUDC comes with an extensive documentation, please refer to it.
|
|
;;
|
|
;; The main entry points of EUDC are:
|
|
;; `eudc-query-form': Query a directory server from a query form
|
|
;; `eudc-expand-inline': Query a directory server for the e-mail address
|
|
;; of the name before cursor and insert it in the
|
|
;; buffer
|
|
;; `eudc-get-phone': Get a phone number from a directory server
|
|
;; `eudc-get-email': Get an e-mail address from a directory server
|
|
;; `eudc-customize': Customize various aspects of EUDC
