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41 ;; are missing or badly out-of-date)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