30 ;; Byte compile the .EL files necessary to dump out xemacs.
|
|
|
31 ;; Use this file like this:
|
|
|
32 ;;
|
|
|
33 ;; temacs -batch -l ../lisp/update-elc.el $lisp
|
|
|
34 ;;
|
|
|
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.
|
|
|
38 ;;
|
|
|
39 ;; (the idea here is that you can bootstrap if your .ELC files
|
|
|
40 ;; are missing or badly out-of-date)
|
|
|
41
|
|
|
42 ;; Currently this code gets the list of files to check passed to it from
|
|
|
43 ;; src/Makefile. This must be fixed. -slb
