;;; Commentary:

;; This mode connects the BBDB to ERC.  Whenever a known nick
;; connects, the corresponding BBDB record pops up.  To identify
;; users, use the irc-nick field.  Define it, if BBDB asks you about
;; that.  When you use /WHOIS on a known nick, the corresponding
;; record will be updated.

;;; History

;; Andreas Fuchs <> wrote zenirc-bbdb-whois.el, which was
;; adapted for ERC by Mario Lang <>.

;; Changes by Edgar Gon�alves <>
;; May 31 2005:
;;     - new variable: erc-bbdb-bitlbee-name-field - the field name for the
;;       msn/icq/etc nick
;;     - nick doesn't go the the name. now it asks for an existing record to
;;       merge with. If none, then create a new one with the nick as name.
