+
+;;; Commentary:
+
+;; This file defines the ERC module `erc-capab-identify', which allows
+;; flagging of unidentified users on servers running dancer-ircd or
+;; hyperion.  freenode.net supports this capability, for example.
+
+;; With CAPAB IDENTIFY-MSG and IDENTIFY-CTCP enabled, messages from
+;; users who have identified themselves to NickServ will have a plus
+;; sign and messages from unidentified users will have a minus sign
+;; added as a prefix.  Note that it is not necessary for your nickname
+;; to be identified in order to receive these marked messages.
+
+;; The plus or minus sign is removed from the message, and a prefix,
+;; `erc-capab-identify-prefix', is inserted in the front of the user's
+;; nickname if the nickname is not identified.
+
+;; Please note that once this has been enabled on a server, there is no
+;; way to tell the server to stop sending marked messages.  If you
+;; disable this module, it will continue removing message flags, but the
+;; unidentified nickname prefix will not be added to messages.
+
+;; Visit <http://freenode.net/faq.shtml#spoofing> and
+;; <http://freenode.net/faq.shtml#registering> to find further
+;; explanations of this capability.
+
+;; From freenode.net's web site (not there anymore) on how to mark
+;; unidentified users:
+;; "We recommend that you add an asterisk before the nick, and
+;;  optionally either highlight or colourize the line in some
+;;  appropriate fashion, if the user is not identified."
+
+;;; Usage:
+
+;; Put the following in your ~/.emacs file.
+
+;; (require 'erc-capab)
+;; (erc-capab-identify-mode 1)
+
+;; `erc-capab-identify-prefix' will now be added to the beginning of
+;; unidentified users' nicknames.  The default is an asterisk, "*".  If
+;; the value of this variable is nil or you disable this module (see
+;; `erc-capab-identify-disable'), no prefix will be inserted, but the
+;; flag sent by the server will still be stripped.
