  26
  27 ;; This file includes stuff to work with pattern matching in ERC. If
  28 ;; you were used to customizing erc-fools, erc-keywords, erc-pals,
  29 ;; erc-dangerous-hosts and the like, this file contains these
  30 ;; customizable variables.
  31
  32 ;; Usage:
  33 ;; Put (erc-match-mode 1) into your ~/.emacs file.
