  28 ;;; !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
  29 ;;; Special formatting conventions are used in this file!
  30 ;;;
  31 ;;; a backslash-newline is used at the beginning of a documentation string
  32 ;;; when that string should be stored in the file etc/DOCnnn, not in core.
  33 ;;;
  34 ;;; Such strings read into Lisp as numbers (during the pure-loading phase).
  35 ;;;
  36 ;;; But you must obey certain rules to make sure the string is understood
  37 ;;; and goes into etc/DOCnnn properly.
  38 ;;;
  39 ;;; The doc string must appear in the standard place in a call to
  40 ;;; defun, autoload, defvar or defconst.  No Lisp macros are recognized.
  41 ;;; The open-paren starting the definition must appear in column 0.
  42 ;;;
  43 ;;; In defvar and defconst, there is an additional rule:
  44 ;;; The double-quote that starts the string must be on the same
  45 ;;; line as the defvar or defconst.
