;;; Commentary:
;; Byte compile the .EL files necessary to dump out xemacs.
;; Use this file like this:
;; temacs -batch -l ../lisp/update-elc.el $lisp
;; where $lisp comes from the Makefile. .elc files listed in $lisp will
;; cause the corresponding .el file to be compiled. .el files listed in
;; $lisp will be ignored.
;; (the idea here is that you can bootstrap if your .ELC files
;; are missing or badly out-of-date)
;; See also update-elc-2.el
