;;; 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
