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40 ;; are missing or badly out-of-date)
