Source Code

;; Defined in /usr/src/emacs/lisp/erc/erc-common.el.gz
;; The default values of some ERC's options contain items defined in
;; other libraries that may not be loaded when `setopt' is invoked on
;; the option, which results in an unfriendly warning.  User configs can
;; simply `require' such dependencies beforehand, but that's often
;; undesirable in ERC's own library code.
