;;; Commentary:

;;; !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
;;; Special formatting conventions are used in this file!
;;;
;;; A backslash-newline is used at the beginning of a documentation string
;;; when that string should be stored in the file etc/DOCnnn, not in core.
;;;
;;; Such strings read into Lisp as numbers (during the pure-loading phase).
;;;
;;; But you must obey certain rules to make sure the string is understood
;;; and goes into etc/DOCnnn properly.
;;;
;;; The doc string must appear in the standard place in a call to
;;; defun, autoload, defvar or defconst.  No Lisp macros are recognized.
;;; The open-paren starting the definition must appear in column 0.
;;;
;;; In defvar and defconst, there is an additional rule:
;;; The double-quote that starts the string must be on the same
;;; line as the defvar or defconst.
;;; !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
