+;;; 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+;; are missing or badly out-of-date)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
