28 | ;; A smart editing mode for m4 macro definitions. It seems to have most of the | |
29 | ;; syntax right (sexp motion commands work, but function motion commands don't). | |
30 | ;; It also sets the font-lock syntax stuff for colorization | |
31 | ||
32 | ;; To Do's: | |
33 | ||
34 | ;; * want to make m4-m4-(buffer|region) look sorta like M-x compile look&feel ? | |
35 | ;; * sexp motion commands don't seem to work right | |
