+;;; Commentary:
+
+;; This file replaces erc-complete.el.  It provides nick completion
+;; for ERC based on pcomplete.  If you do not have pcomplete, you may
+;; try to use erc-complete.el.
+;;
+;; To use, (require 'erc-auto) or (require 'erc-pcomplete), then
+;;   (erc-pcomplete-mode 1)
+;;
+;; If you want nickname completions ordered such that the most recent
+;; speakers are listed first, set
+;; `erc-pcomplete-order-nickname-completions' to `t'.
+;;
+;; See CREDITS for other contributors.
